I'm trying to create a JQM survey with branching questions--i.e. in a survey with questions 1-3, if you choose a particular answer on question 1, a question is dynamically added between questions 1 and 2.
UPDATE: I made an attempt ( https://dl.dropbox.com/u/17841063/site2/index-c1.html#page2 ) that works by matching the value of a radio button to the name of a hidden div--if there's a match, it unhides the div. The problem right now is that if you change your answer back to an option that wouldn't trigger the conditional question, it doesn't re-hide. For example, clicking No or Unsure in question A1 causes question A2 to appear, but if you then click Yes in A1, A2 still remains...
<script type="text/javascript">
// Place in this array the ID of the element you want to hide
var hide=['A2','A4'];
function setOpt()
{
resetOpt(); // Call the resetOpt function. Hide some elements in the "hide" array.
for(var i=0,sel=document.getElementsByTagName('input');i<sel.length;i++)
{
sel[i].onchange=function()
{
if(this.parentNode.tagName.toLowerCase()!='div')
resetOpt(); // Hides the elements in "hide" array when the first select element is choosen
try
{
document.getElementById(this.value).style.display='';
}
catch(e){} ; // When the value of the element is not an element ID
}
}
}
window.addEventListener?window.addEventListener('load',setOpt,false):
window.attachEvent('onload',setOpt);
function resetOpt()
{
for(var i=0;i<hide.length;i++)
document.getElementById(hide[i]).style.display='none'; // Hide the elements in "hide" array
}
</script>
Here's are the radio buttons that use the script above:
<div data-role="fieldcontain">
<fieldset data-role="controlgroup" data-type="horizontal">
<legend>(Question A1) A prominent accident smokes on top of the blessed reactionary?</legend>
<input type="radio" name="aaa" id="aaa_0" value="notA2" />
<label for="aaa_0">Yes</label>
<input type="radio" name="aaa" id="aaa_1" value="A2" />
<label for="aaa_1">No</label>
<input type="radio" name="aaa" id="aaa_2" value="A2" />
<label for="aaa_2">Unsure</label>
</fieldset>
</div>
<div id="A2" data-role="fieldcontain">
<fieldset data-role="controlgroup" data-type="horizontal">
<legend>(Question A2) Does a married composite remainder the shallow whistle??</legend>
<input type="radio" name="bbb" id="bbb_0" value="" />
<label for="bbb_0">Yes</label>
<input type="radio" name="bbb" id="bbb_1" value="" />
<label for="bbb_1">No</label>
<input type="radio" name="bbb" id="bbb_2" value="" />
<label for="bbb_2">Unsure</label>
</fieldset>
</div>
If anyone has ideas about fixing this, or examples of other ways to do branching forms, I'd be very grateful!
Thanks,
Patrick
I played around a little bit with your example, removed all your plain JavaScript and added some jQuery Mobile style script, see working example here
<script>
$("input[type='radio']").bind( "change", function(event, ui) {
var mySelection = $('input[name=aaa]:checked').val();
//alert(mySelection);
if (mySelection == "A2") {
$('#A2').removeClass('ui-hidden-accessible');
} else {
$('#A2').addClass('ui-hidden-accessible');
};
});
</script>

I would like to create a validator for abide for a set of checkboxes.
Let's consider a set of 5 checkboxes. The user is asked to check 3 max, and at least 1.
So, here is my work-in-progress code:
<div data-abide-validator='checkboxes' data-abide-validator-values='1,3'>
<input type="checkbox"/>
<input type="checkbox"/>
<input type="checkbox"/>
<input type="checkbox"/>
<input type="checkbox"/>
</div>
<script>
$(document).foundation({
validators: {
checkboxes: function(el, required, parent) {
var countC = el.find(':checked').length;
alert(countC);
}
}
});
</script>
At this point, I just try to count the checked inputs. But it seems I can't even trigger the validator... I think I could manage to code my validation stuff if only I could figure out how to trigger it.
Indeed I didn't find many examples of the custom validator, and the official doc did not help me much.
Your HTML markup is not really "correct" for abide. You should be attaching the data-abide-validator attribute to the inputs, not the parent div. Additionally, you need some better markup so abide's default error display can work (and some better use of foundation's grid system to lay it out). I would point you toward the Abide Validation Page on Zurb's site for some examples of form markup.
I've taken the liberty of restructuring your markup to be something that is more becoming of a foundation layout:
<form action="/echo/html/" method="POST" data-abide>
<div class="row">
<div class="small-12 columns checkbox-group" data-abide-validator-limit="1,3">
<label>Check some boxes</label>
<small class="error">You have checked an invalid number of boxes.</small>
<ul class="small-block-grid-3">
<li>
<label>
<input type="checkbox" data-abide-validator="checkbox_limit" value="1" /> 1
</label>
</li>
<li>
<label>
<input type="checkbox" data-abide-validator="checkbox_limit" value="2" /> 2
</label>
</li>
<li>
<label>
<input type="checkbox" data-abide-validator="checkbox_limit" value="3" /> 3
</label>
</li>
<li>
<label>
<input type="checkbox" data-abide-validator="checkbox_limit" value="4" /> 4
</label>
</li>
<li>
<label>
<input type="checkbox" data-abide-validator="checkbox_limit" value="5" /> 5
</label>
</li>
</ul>
</div>
</div>
<div class="row">
<div class="small-12 columns">
<button type="submit">Submit</button>
</div>
</div>
</form>
As to your JS code. It's not correct either. You need to address the abide -> validators namespace of the options, not just validators. I've rewritten your JS code to not only do that, but give the desired effect you wanted:
$(document).foundation({
abide: {
validators: {
checkbox_limit: function(el, required, parent) {
var group = parent.closest( '.checkbox-group' );
var limit = group.attr('data-abide-validator-limit').split(',');
var countC = group.find(':checked').length;
if( countC >= limit[0] && countC <= limit[1] ) {
group.find('small.error').hide();
//return true so abide can clear any invalid flags on this element
return true;
} else {
group.find('small.error').css({display:'block'});
//return false and let abide do its thing to make sure the form doesn't submit
return false;
}
}
}
}
});
In order to check adjacent elements when doing custom validation, you need to have something to target. The el variable in the validation function will be the DOM element of the input/field that is being validated. The required variable will tell you if the field is flagged as being required or not (boolean). The parent variable will be set to the "parent" of the field. I say "parent" because although the label tag is technically the parent of the input element, abide is smart enough to realize that the label is part of the field's element structure and skip over it to the li element instead.
From there, you need a way to identify a common parent. So I added the checkbox-group class to whatever element I decided to make the "parent" of all the checkboxes in the group. This is not a Foundation or Abide "magic" class, but rather something of my own creation for use in the validation function.
From there, you can easily trace the few lines of the validation function to see the workflow: Find the group container object, parse the limits off the container's data-abide-validator-limits attribute, count the number of checked inputs in the container, check if the number checked is between the limits, display/hide the error message and return true/false so abide knows if the field validated or not.
I've got a working Fiddle of it if you care to check it out yourself ;) Hopefully this was informative for you, and I wish you the best of luck playing with the awesome that is Foundation!
Here's what I have, below, trying to use bits from similar answers here, plus items from the parsley site.. Nothing happens..User is not alerted that at least 1 box must be checked. Do I have this all wrong? Thank you in advance for any clues!
<form action="success.html" id="contact-form" data-parsley-validate>
<label for="language">Please Choose your Language:<br>
<input type="checkbox" class="checkbox" name="language" value="english" parsley-group="language" parsley-mincheck="1">English<br>
<input type="checkbox" class="checkbox" name="language" value="spanish" parsley-group="language" >Spanish<br>
<input type="checkbox" class="checkbox" name="language" value="french" parsley-group="language" >French
</label>
You have some problems with your code:
parsley-group doesn't exist. There is a data-parsley-group and is applicable if you want to validate a portion of your form.
parsley-mincheck="1" doesn't exist. There is a data-parsley-mincheck="1".
Assuming that you require at least one language, but can accept more, this code should do the trick:
<form action="success.html" id="contact-form" data-parsley-validate>
<label for="language">Please Choose your Language:<br>
<input type="checkbox" class="checkbox" name="language[]"
value="english" required>English<br>
<input type="checkbox" class="checkbox" name="language[]"
value="spanish" required>Spanish<br>
<input type="checkbox" class="checkbox" name="language[]"
value="french" required >French</label>
<button type="submit" id="submit-button">Submit form</button>
</form>
$(document).ready(function() {
// bind parsley to the form
$("#contact-form").parsley();
// on form submit, validate form and, if valid, show valid in the console
$("#contact-form").submit(function() {
$(this).parsley("validate");
if ($(this).parsley("isValid")) {
console.log('valid');
}
event.preventDefault();
});
});
If you want the user to select one and only one option, I advice you to use radio buttons.
I'm making a form. And on one input tag is an OnClick event handler, which is opening a popup, where you can choose some stuff, and then it autofills the input tag.
That input tag is also readonly, so only right data will be entered.
This is the code of the input tag:
<input type="text" name="formAfterRederict" id="formAfterRederict" size="50" required readonly="readonly" OnClick="choose_le_page();" />
But the required attribute isn't working in Chrome. But the field is required.
Does anybody know how I can make it work?
I had same requirement as yours and I figured out an easy way to do this.
If you want a "readonly" field to be "required" also (which is not supported by basic HTML), and you feel too lazy to add custom validation, then just make the field read only using jQuery this way:
IMPROVED
form the suggestions in comments
<input type="text" class="readonly" autocomplete="off" required />
<script>
$(".readonly").on('keydown paste focus mousedown', function(e){
if(e.keyCode != 9) // ignore tab
e.preventDefault();
});
</script>
Credits: #Ed Bayiates, #Anton Shchyrov, #appel, #Edhrendal, #Peter Lenjo
ORIGINAL
<input type="text" class="readonly" required />
<script>
$(".readonly").keydown(function(e){
e.preventDefault();
});
</script>
readonly fields cannot have the required attribute, as it's generally assumed that they will already hold some value.
Remove readonly and use function
<input type="text" name="name" id="id" required onkeypress="return false;" />
It works as you want.
Required and readonly don't work together.
But readonly can be replaced with following construction:
<input type="text"
onkeydown="return false;"
style="caret-color: transparent !important;"
required>
1) onkeydown will stop manipulation with data
2) style="caret-color: transparent !important;" will hide cursor.
3) you can add style="pointer-events: none;" if you don't have any events on your input, but it was not my case, because I used a Month Picker. My Month picker is showing a dialog on click.
This is by design. According to the official HTML5 standard drafts, "if the readonly attribute is specified on an input element, the element is barred from constraint validation." (E.g. its values won't be checked.)
Yes, there is a workaround for this issue. I found it from https://codepen.io/fxm90/pen/zGogwV site.
Solution is as follows.
HTML File
<form>
<input type="text" value="" required data-readonly />
<input type="submit" value="Submit" />
</form>
CSS File
input[data-readonly] {
pointer-events: none;
}
If anyone wants to do it only from html, This works for me.
<input type="text" onkeydown="event.preventDefault()" required />
I think this should help.
<form onSubmit="return checkIfInputHasVal()">
<input type="text" name="formAfterRederict" id="formAfterRederict" size="50" required readonly="readonly" OnClick="choose_le_page();" />
</form>
<script>
function checkIfInputHasVal(){
if($("#formAfterRederict").val==""){
alert("formAfterRederict should have a value");
return false;
}
}
</script>
You can do this for your template:
<input required onfocus="unselect($event)" class="disabled">
And this for your js:
unselect(event){
event.preventDefault();
event.currentTarget.blur();
}
For a user the input will be disabled and required at the same time, providing you have a css-class for disabled input.
Based on answer #KanakSinghal but without blocked all keys and with blocked cut event
$('.readonly').keydown(function(e) {
if (e.keyCode === 8 || e.keyCode === 46) // Backspace & del
e.preventDefault();
}).on('keypress paste cut', function(e) {
e.preventDefault();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" class="readonly" value="test" />
P.S. Somebody knows as cut event translate to copy event?
Required and readonly don't work together.
Although you can make two inputs like this:
<input id="One" readonly />
<input id="Two" required style="display: none" /> //invisible
And change the value Two to the value that´s inside the input One.
I have the same problem, and finally I use this solution (with jQuery):
form.find(':input[required][readonly]').filter(function(){ return this.value === '';})
In addition to the form.checkValidity(), I test the length of the above search somehow this way:
let fcnt = $(form)
.find(':input[required][readonly]')
.filter(function() { return this.value === '';})
.length;
if (form.checkValidity() && !fcnt) {
form.submit();
}
function validateForm() {
var x = document.forms["myForm"]["test2"].value;
if (x == "") {
alert("Name missing!!");
return false;
}
}
<form class="form-horizontal" onsubmit="return validateForm()" name="myForm" action="" method="POST">
<input type="text" name="test1">
<input type="text" disabled name="test2">
<button type="submit">Submit</button>
</form>
what I want to create is a select element that has values determined by a selection in a pair of radio-button ('parent'):
<p>
How many dimensions?
<input type="radio" name="dimension" value="2D" data-bind="checked: dimSelect" />2D
<input type="radio" name="dimension" value="3D" data-bind="checked: dimSelect" />3D
</p>
<p data-bind="text: dimSelect"></p>
<p data-bind="visible: dimSelect">
Which geometry? <select data-bind="options: geometry, optionsCaption: 'Choose'"></select>
</p>
My viewmodel now is:
<script type="text/javascript">
function viewModel(){
dimSelect = ko.observable();
if (dimSelect() == '2D') {
alert('2D: ' + dimSelect());
geometrie = ko.observableArray(['Circle', 'Quadrant', 'Triangle']);
} else {
alert('3D: ' + dimSelect());
geometrie = ko.observableArray(['Cilinder', 'Cube', 'Widge']);
};
}
ko.applyBindings(new viewModel());
</script>
But for some reason I can get the dimSelect value represented in the text binder but not in the if statement in my viewModel. It is undefined (so 3D applies).
I'm probably doing some newbie thing wrong like the entire theoretical approach, so please keep your answer as practical/understandable as possible.
Thanks for your time and patience!
There are several ways that you can approach this one.
In your current code, you are creating some global variables in your constructor function rather than attaching them to the new instance of the object that you are creating (this).
Here is another way to do it:
<p>
How many dimensions?
<input type="radio" name="dimension" value="2D" data-bind="checked: dimSelect" />2D
<input type="radio" name="dimension" value="3D" data-bind="checked: dimSelect" />3D
</p>
<p data-bind="text: dimSelect"></p>
<p data-bind="with: dimSelect">
Which geometry? <select data-bind="options: $root.dimensions[$data], optionsCaption: 'Choose'"></select>
</p>
js:
function ViewModel() {
this.dimSelect = ko.observable();
this.dimensions = {
'2D': ['Circle', 'Quadrant', 'Triangle'],
'3D': ['Cilinder', 'Cube', 'Widge']
};
}
ko.applyBindings(new ViewModel());

This question already has answers here:
Using the HTML5 "required" attribute for a group of checkboxes?
(16 answers)
Closed 6 years ago.
I have a list of checkboxes with the same name attribute, and I need to validate that at least one of them has been selected.
But when I use the html5 attribute "required" on all of them, the browser (chrome & ff) doesn't allow me to submit the form unless all of them are checked.
sample code:
<label for="a-0">a-0</label>
<input type="checkbox" name="q-8" id="a-0" required />
<label for="a-1">a-1</label>
<input type="checkbox" name="q-8" id="a-1" required />
<label for="a-2">a-2</label>
<input type="checkbox" name="q-8" id="a-2" required />
When using the same with radio inputs, the form works as expected (if one of the options is selected the form validates)
According to Joe Hopfgartner (who claims to quote the html5 specs), the supposed behaviour is:
For checkboxes, the required attribute shall only be satisfied when one or more of the checkboxes with that name in that form are checked.
For radio buttons, the required attribute shall only be satisfied when exactly one of the radio buttons in that radio group is checked.
am i doing something wrong, or is this a browser bug (on both chrome & ff) ??
You can make it with jQuery a less lines:
$(function(){
var requiredCheckboxes = $(':checkbox[required]');
requiredCheckboxes.change(function(){
if(requiredCheckboxes.is(':checked')) {
requiredCheckboxes.removeAttr('required');
}
else {
requiredCheckboxes.attr('required', 'required');
}
});
});
With $(':checkbox[required]') you select all checkboxes with the attribute required, then, with the .change method applied to this group of checkboxes, you can execute the function you want when any item of this group changes. In this case, if any of the checkboxes is checked, I remove the required attribute for all of the checkboxes that are part of the selected group.
I hope this helps.
Farewell.
Sorry, now I've read what you expected better, so I'm updating the answer.
Based on the HTML5 Specs from W3C, nothing is wrong. I created this JSFiddle test and it's behaving correctly based on the specs (for those browsers based on the specs, like Chrome 11 and Firefox 4):
<form>
<input type="checkbox" name="q" id="a-0" required autofocus>
<label for="a-0">a-1</label>
<br>
<input type="checkbox" name="q" id="a-1" required>
<label for="a-1">a-2</label>
<br>
<input type="checkbox" name="q" id="a-2" required>
<label for="a-2">a-3</label>
<br>
<input type="submit">
</form>
I agree that it isn't very usable (in fact many people have complained about it in the W3C's mailing lists).
But browsers are just following the standard's recommendations, which is correct. The standard is a little misleading, but we can't do anything about it in practice. You can always use JavaScript for form validation, though, like some great jQuery validation plugin.
Another approach would be choosing a polyfill that can make (almost) all browsers interpret form validation rightly.
To provide another approach similar to the answer by #IvanCollantes.
It works by additionally filtering the required checkboxes by name. I also simplified the code a bit and checks for a default checked checkbox.
jQuery(function($) {
var requiredCheckboxes = $(':checkbox[required]');
requiredCheckboxes.on('change', function(e) {
var checkboxGroup = requiredCheckboxes.filter('[name="' + $(this).attr('name') + '"]');
var isChecked = checkboxGroup.is(':checked');
checkboxGroup.prop('required', !isChecked);
});
requiredCheckboxes.trigger('change');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form target="_blank">
<p>
At least one checkbox from each group is required...
</p>
<fieldset>
<legend>Checkboxes Group test</legend>
<label>
<input type="checkbox" name="test[]" value="1" checked="checked" required="required">test-1
</label>
<label>
<input type="checkbox" name="test[]" value="2" required="required">test-2
</label>
<label>
<input type="checkbox" name="test[]" value="3" required="required">test-3
</label>
</fieldset>
<br>
<fieldset>
<legend>Checkboxes Group test2</legend>
<label>
<input type="checkbox" name="test2[]" value="1" required="required">test2-1
</label>
<label>
<input type="checkbox" name="test2[]" value="2" required="required">test2-2
</label>
<label>
<input type="checkbox" name="test2[]" value="3" required="required">test2-3
</label>
</fieldset>
<hr>
<button type="submit" value="submit">Submit</button>
</form>
i had the same problem, my solution was apply the required attribute to all elements
<input type="checkbox" name="checkin_days[]" required="required" value="0" /><span class="w">S</span>
<input type="checkbox" name="checkin_days[]" required="required" value="1" /><span class="w">M</span>
<input type="checkbox" name="checkin_days[]" required="required" value="2" /><span class="w">T</span>
<input type="checkbox" name="checkin_days[]" required="required" value="3" /><span class="w">W</span>
<input type="checkbox" name="checkin_days[]" required="required" value="4" /><span class="w">T</span>
<input type="checkbox" name="checkin_days[]" required="required" value="5" /><span class="w">F</span>
<input type="checkbox" name="checkin_days[]" required="required" value="6" /><span class="w">S</span>
when the user check one of the elements i remove the required attribute from all elements:
var $checkedCheckboxes = $('#recurrent_checkin :checkbox[name="checkin_days[]"]:checked'),
$checkboxes = $('#recurrent_checkin :checkbox[name="checkin_days[]"]');
$checkboxes.click(function() {
if($checkedCheckboxes.length) {
$checkboxes.removeAttr('required');
} else {
$checkboxes.attr('required', 'required');
}
});
Here is improvement for icova's answer. It also groups inputs by name.
$(function(){
var allRequiredCheckboxes = $(':checkbox[required]');
var checkboxNames = [];
for (var i = 0; i < allRequiredCheckboxes.length; ++i){
var name = allRequiredCheckboxes[i].name;
checkboxNames.push(name);
}
checkboxNames = checkboxNames.reduce(function(p, c) {
if (p.indexOf(c) < 0) p.push(c);
return p;
}, []);
for (var i in checkboxNames){
!function(){
var name = checkboxNames[i];
var checkboxes = $('input[name="' + name + '"]');
checkboxes.change(function(){
if(checkboxes.is(':checked')) {
checkboxes.removeAttr('required');
} else {
checkboxes.attr('required', 'required');
}
});
}();
}
});
A little jQuery fix:
$(function(){
var chbxs = $(':checkbox[required]');
var namedChbxs = {};
chbxs.each(function(){
var name = $(this).attr('name');
namedChbxs[name] = (namedChbxs[name] || $()).add(this);
});
chbxs.change(function(){
var name = $(this).attr('name');
var cbx = namedChbxs[name];
if(cbx.filter(':checked').length>0){
cbx.removeAttr('required');
}else{
cbx.attr('required','required');
}
});
});
Building on icova's answer, here's the code so you can use a custom HTML5 validation message:
$(function() {
var requiredCheckboxes = $(':checkbox[required]');
requiredCheckboxes.change(function() {
if (requiredCheckboxes.is(':checked')) {requiredCheckboxes.removeAttr('required');}
else {requiredCheckboxes.attr('required', 'required');}
});
$("input").each(function() {
$(this).on('invalid', function(e) {
e.target.setCustomValidity('');
if (!e.target.validity.valid) {
e.target.setCustomValidity('Please, select at least one of these options');
}
}).on('input, click', function(e) {e.target.setCustomValidity('');});
});
});
var verifyPaymentType = function () {
//coloque os checkbox dentro de uma div com a class checkbox
var inputs = window.jQuery('.checkbox').find('input');
var first = inputs.first()[0];
inputs.on('change', function () {
this.setCustomValidity('');
});
first.setCustomValidity( window.jQuery('.checkbox').find('input:checked').length === 0 ? 'Choose one' : '');
}
window.jQuery('#submit').click(verifyPaymentType);
}
