Submit Search on Enter Key? - forms

What needs to be done to have this form submitted when someone hits the 'enter' key?
<form id="search" onsubmit="javascript:search(document.getElementById('searchText'))">
<input type='text' id='searchText' autofocus />
<input type='button' onclick="search(document.getElementById('searchText'))" value='Search' />
</form>

You can just use a form as below, with input type submit, which in this case, if you press enter in any input - if you had more of them - it will be a default behaviour of the form to be submitted:
<form id="search">
<input type='text' id='searchText' />
<input type='submit' value='Search' />
</form>
or, as it shows, you want to use the onsubmit function and handle the "submit" of the form, so you can do this:
<form id="search" action="#">
<input type="text" id='searchText' name="myinput" onkeypress="handle" />
</form>
<script>
function handle(e){
if(e.key === "Enter"){
alert("Enter was just pressed.");
}
return false;
}
</script>
A code, quite the same, can be found on this similar question: How to capture Enter key press?
Hope I answered your question, even out of time.

This example worked perfectly for me:
var input = document.getElementById("myInput");
// Execute a function when the user releases a key on the keyboard
input.addEventListener("keyup", function(event) {
// Number 13 is the "Enter" key on the keyboard
if (event.keyCode === 13) {
// Cancel the default action, if needed
event.preventDefault();
// Trigger the button element with a click
document.getElementById("myBtn").click();
}
});
I took the example at w3schools.

clear form values with reset button

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.

Text form that follows link

I have to create a form with a submit bottom following a link
<form action="http://domain/**(((MY TEXT INPUT VALUE)))**.htm">
<input type="text" name="verb">
<input type="submit" value="Conjugate">
</form>
something like this.
please note that every link should be different.
I also want that the new page be opened in a new tab/window
could you please help me, and also make changes to the form code if there is sth under newer standards. Thank you!
You need to use javascript to get the TEXTBOX value and then place it into the form action.
You can create the submit button with an onclickevent.
Or you can use jQuery
$('#btnSubmit').click(function(){
var sTextValue = $("#MyText").val();
$('#MyForm').attr('action', 'htttp://domain/' + sTextValue + '.htm');
$('#MyForm').submit();
});
And the HTML
<form id="MyForm" action="">
<input id="MyText" type="text" name="verb">
<input id="btnSubmit" type="button" value="Conjugate">
</form>
There are many ways to accomplish this. That's just one of them.
<form action="http://domain/**(((MY TEXT INPUT VALUE)))**.htm" id="btnForm">
<input type="text" name="verb" onchange='javascript:document.getElementById("btnForm").action = "http://domain/"+ this.value +".htm"'>
<input type="submit" value="Conjugate" >
</form
This would update as soon you type the text. It wouldn't require jquery. it makes use of onchange event handler of input type text
<form action="http://domain/**(((MY TEXT INPUT VALUE)))**.htm" id="btnForm">
<input type="text" name="verb" onchange='updateFormAction(this.value)'>
<input type="submit" value="Conjugate" >
</form>
<script type="text/javascript">
function updateFormAction(value){
var btnForm = document.getElementById("btnForm");
btnForm.action = "http://domain/"+ value +".htm";
}
</script>
This is more explanatory form. Its based on onchange event handler for text types.

Adding an extra relative value to an input value field

I'm currently creating a form that is very similar to the following code.
<form name="test" action="/go/test" method="post">
<input type=hidden name="hotspot_url" value="http://www.test.com/">
<input name="cky" value="<%write(cky);%>" type="hidden">
<input name="accept" value="Accept" type="hidden">
<input name="saccept" size="20" value="I Accept" onClick="hotspot.accept.value='Accept'" type="submit">
<input name="sdisconnect" size="20" value="I Decline" onClick="hotspot.accept.value='Decline'" type="submit">
</form>
However, the new form has a text input field. What I want to achieve is that the value entered in that text field is placed, upon send, after the test.com value (location marked with xxx)
<input type=hidden name="hotspot_url" value="http://www.test.com/xxx">
I've looked around - but i can't seem to find a solution.
What would be the best way to get this done?
You can use a buttons onclick event, which is not of type submit. When onclick occurs, you can first change the value of hidden field and then submit the form.
Or if you use JQuery, you can use the following jQuery code to do something before the form is submitted:
$(function() {
$('#form').submit(function() {
// DO STUFF
return true; // return false to cancel form action
});
});
You can give both inputs an id, and do something like this:
give the form an "onsumbit= doThis()"
function doThis(){
var hiddeninput= $('#hiddeninput').val();
var input = $('#input').val();
$('#hiddeninput').val(hiddeninput+input);
return true;
}
this is very simple nothing fancy.

HTML required readonly input in form

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>

onsubmit() does not call my function but the form does get submitted

I have a external js file that has the following function in it. It is supped to be called by the forms onsubmit but it doesn't appear to be happening. The form is just submitted without validation. At one point this was working but now it is not. Where am I going wrong? Any help is appreciated.
function validateDelete(form)
{
alert("Validation Started!");
var photoName=form.deleteName;
if (photoName === "")
{
alert("Photo Name Required");
return false;
}
}
<script src="galleryScripts/validation.js" type="text/javascript" ></script>
<form action="galleryScripts/deletePhoto.php?submit=true" name="deleteForm" onsubmit="return validateDelete(this);" id="deleteForm" method="post">
<label>
File Name: <input name="deleteName" type="text" id="deleteName">
</label>
<label>
<input type="submit" name="deleteButton" id="deleteButton" value="Delete" />
</label>
</form>
Make sure that your js is included.
For example under mozilla press CTRL+U and click on a link to your validation.js file.
Also you can just paste in tag in your tag it should work.
