I want to reset a form which will blank all input field and checkbox.
But here's my code doesn't work.
<form id="rwdPromotionDetailsAdd">
<input type="button" onclick="resetForm()" value="Reset form">
</form>
<script>
function resetForm() {
document.getElementById("rwdPromotionDetailsAdd").reset();
}
<script>
How can i reset a form ? Any better suggestion ?
You just need to insert this within a form
<input type="reset" value="Reset form">
Don't even have to attach a listener to it
<form id="rwdPromotionDetailsAdd">
<input type="button" onclick="resetForm($('#rwdPromotionDetailsAdd'))" value="Reset form">
</form>
<script>
function resetForm($form) {
$form.find('input:text, input:password, input:file, select, textarea').val('');
$form.find('input:radio, input:checkbox').removeAttr('checked').removeAttr('selected');
}
<script>
Alright I could use a small tip here:
I have a form with two buttons, one has to submit the form and the other one has to reset the complete form.
The text - field keeps its value after every submit, but I would like to clear it completely with the reset button
<form method="post">
<input type="text" name="text" value="Clear Me Please">
<button type="submit" name="submit">Submit</button>
<button type="reset" name="reset">Reset</button>
</form>
I have a input field, submit button and a reset button. Upon submiting the form the user input will be inserted as value, because I dont want to lose the input. Now, when I type something into the field I can reset the form as planed, but after submiting the value now stays as supposed, but pressing the reset button resets the input to the value.
Example: I type in "TEXT", press Reset, gets reseted to "". Type "TEXT2", press Submit, gets submited, put in as value, field has now "TEXT2" written in. Replace "TEXT2" with "TEXT3", press Reset, now field contains "TEXT2" instead of "". I hope this is explaination enough.
may a little bit more you have to do

I am using parsley.js 2.0.2. for client side form validation.
Now I noticed on the Parsley Website that parsley 2.x has dynamic form validation.
I have a form on my page with parsley. It works correctly and does validate. Now on the same page I have a link that dynamically adds a form from an external file. Issue is now parsley.js won't validate the newly added form.
On the parsley website they have an example where one can use JavaScript to validate but I tried it and it does not work. Here is the snippet code of the example:
<script src="jquery.js"></script>
<script src="parsley.min.js"></script>
<form id="form">
...
</form>
<script type="text/javascript">
$('#form').parsley();
</script>
I am aware that the content in the DOM changed but is there a way that I can tell parsley to validate this newly added form or something that will trigger the validation process?
I will appreciate the help!
Thanks
Here is my form on the index.php page (This form does successfully validate):
<form action="server.php" method="post" name="main-form" id="myForm" data-parsley-validate>
<div>
<label for="njsform-name">Name</label>
<input name="name" type="text" id="njsform-name" placeholder="Mike" data-parsley-required="true" data-parsley-minlength="2">
</div>
<div>
<label for="njsform-email">Surname</label>
<input name="email" type="text" id="njsform-email" placeholder="Gates" data-parsley-required="true" parsley-minlength="2">
</div>
<div class="submitWrap">
<input class="submit" type="submit" value="Apply Now" />
</div>
Here is the link that gets the external content
<ul class="services-list">
<li><a class="s-option" href="views/form-short_term_loans.php">My Link</a></li>
</ul>
Here is the code I am using to dynamically change the content (does successfully retrieve external form and populates):
$(document).ready(function() {
var hash = window.location.hash.substr(1);
var href = $('.services-list li a').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-5)){
var toLoad = hash+'.html #form-section';
$('#form-section').load(toLoad)
}
});
$('.services-list li a').click(function(){
var toLoad = $(this).attr('href')+' #form-section';
$('#form-section').hide('fast',loadContent);
$('#load').remove();
$('#intro-section').append('<span id="load">Getting required form...</span>');
$('#load').fadeIn('normal');
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-5);
function loadContent() {
$('#form-section').load(toLoad,'',showNewContent())
}
function showNewContent() {
$('#form-section').show('normal',hideLoader());
}
function hideLoader() {
$('#load').fadeOut('normal');
}
return false;
});
});
The second form is just a duplicate but the form id is myForm2 and the name second-form
Add a call to
$('#xxxxxx').parsley();
After the load of the new form. With xxxxx the id of the new form inserted in the DOM
So I wrote this code so that every time someone clicks the submit button, a javascript
function, called check, will see if the text area is empty. If it is not, then the form will be submitted.
This is my code. Why isn't it working?
<form method=post name='form_post' id='form_post' action='SUBMITIT.PHP'>
<textarea id=message name=message class=post onfocus=this.className='post_focus';
placeholder='Share your thoughts' maxlength=500></textarea>
<br>
<button onclick='check()' id=button name=button>Post</button>
</form>
<script type="text/javascript">
function check()
{
if(!document.textArea.message.value=="")
{
document.forms["form_post"].submit();
}
}
</script>
Thanks!
EDIT: I finally got it to work. Here's a template if you are having a similar problem.
<!--The form-->
<form action="mypage.php" method="post" name="myForm" id="myForm">
<textarea name=myTextArea id=myTextArea>
</textarea>
</form>
<br>
<button onclick='check()'>
Post
</button>
<!--The script that checks-->
<script type="text/javascript">
function check(){
String.prototype.trim = function() { return this.replace(/^\s+|\s+$/g, ""); };
var textAreaValue=document.getElementById('myTextArea').value;
var trimmedTextAreaValue=textAreaValue.trim();
if(trimmedTextAreaValue!="") {
document.forms["myForm"].submit();
}
}
</script>
The following woks, and it also wipes unnecessary spaces, the form will only submit when given a character
<form action="yourpage.php" method="post" onsubmit="return check(this)">
<textarea id="message"></textarea>
<input type="submit" value="Post" />
</form>
<script>
function check(form){
if (form.message.value.trim() == ""){
return false
}
}
</script>
This is the most simple way to do this, and the advised one.
You could simply add "required" to the textarea field in HTML.
Note: Although the question is quite old, I am adding the answer for the future references.
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>

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>
