How to disable submit button? [duplicate] - javascript

I wrote this code to disable submit buttons on my website after the click:
$('input[type=submit]').click(function(){
$(this).attr('disabled', 'disabled');
});
Unfortunately, it doesn't send the form. How can I fix this?
EDIT
I'd like to bind the submit, not the form :)

Do it onSubmit():
$('form#id').submit(function(){
$(this).find(':input[type=submit]').prop('disabled', true);
});
What is happening is you're disabling the button altogether before it actually triggers the submit event.
You should probably also think about naming your elements with IDs or CLASSes, so you don't select all inputs of submit type on the page.
Demonstration: http://jsfiddle.net/userdude/2hgnZ/
(Note, I use preventDefault() and return false so the form doesn't actual submit in the example; leave this off in your use.)

Specifically if someone is facing problem in Chrome:
What you need to do to fix this is to use the onSubmit tag in the <form> element to set the submit button disabled. This will allow Chrome to disable the button immediately after it is pressed and the form submission will still go ahead...
<form name ="myform" method="POST" action="dosomething.php" onSubmit="document.getElementById('submit').disabled=true;">
<input type="submit" name="submit" value="Submit" id="submit">
</form>

Disabled controls do not submit their values which does not help in knowing if the user clicked save or delete.
So I store the button value in a hidden which does get submitted. The name of the hidden is the same as the button name. I call all my buttons by the name of button.
E.g. <button type="submit" name="button" value="save">Save</button>
Based on this I found here. Just store the clicked button in a variable.
$(document).ready(function(){
var submitButton$;
$(document).on('click', ":submit", function (e)
{
// you may choose to remove disabled from all buttons first here.
submitButton$ = $(this);
});
$(document).on('submit', "form", function(e)
{
var form$ = $(this);
var hiddenButton$ = $('#button', form$);
if (IsNull(hiddenButton$))
{
// add the hidden to the form as needed
hiddenButton$ = $('<input>')
.attr({ type: 'hidden', id: 'button', name: 'button' })
.appendTo(form$);
}
hiddenButton$.attr('value', submitButton$.attr('value'));
submitButton$.attr("disabled", "disabled");
}
});
Here is my IsNull function. Use or substitue your own version for IsNull or undefined etc.
function IsNull(obj)
{
var is;
if (obj instanceof jQuery)
is = obj.length <= 0;
else
is = obj === null || typeof obj === 'undefined' || obj == "";
return is;
}

Simple and effective solution is
<form ... onsubmit="myButton.disabled = true; return true;">
...
<input type="submit" name="myButton" value="Submit">
</form>
Source: here

This should take care of it in your app.
$(":submit").closest("form").submit(function(){
$(':submit').attr('disabled', 'disabled');
});

A more simplier way.
I've tried this and it worked fine for me:
$(':input[type=submit]').prop('disabled', true);

Want to submit value of button as well and prevent double form submit?
If you are using button of type submit and want to submit value of button as well, which will not happen if the button is disabled, you can set a form data attribute and test afterwards.
// Add class disableonsubmit to your form
$(document).ready(function () {
$('form.disableonsubmit').submit(function(e) {
if ($(this).data('submitted') === true) {
// Form is already submitted
console.log('Form is already submitted, waiting response.');
// Stop form from submitting again
e.preventDefault();
} else {
// Set the data-submitted attribute to true for record
$(this).data('submitted', true);
}
});
});

Your code actually works on FF, it doesn't work on Chrome.
This works on FF and Chrome.
$(document).ready(function() {
// Solution for disabling the submit temporarily for all the submit buttons.
// Avoids double form submit.
// Doing it directly on the submit click made the form not to submit in Chrome.
// This works in FF and Chrome.
$('form').on('submit', function(e){
//console.log('submit2', e, $(this).find('[clicked=true]'));
var submit = $(this).find('[clicked=true]')[0];
if (!submit.hasAttribute('disabled'))
{
submit.setAttribute('disabled', true);
setTimeout(function(){
submit.removeAttribute('disabled');
}, 1000);
}
submit.removeAttribute('clicked');
e.preventDefault();
});
$('[type=submit]').on('click touchstart', function(){
this.setAttribute('clicked', true);
});
});
</script>

How to disable submit button
just call a function on onclick event and... return true to submit and false to disable submit.
OR
call a function on window.onload like :
window.onload = init();
and in init() do something like this :
var theForm = document.getElementById(‘theForm’);
theForm.onsubmit = // what ever you want to do

The following worked for me:
var form_enabled = true;
$().ready(function(){
// allow the user to submit the form only once each time the page loads
$('#form_id').on('submit', function(){
if (form_enabled) {
form_enabled = false;
return true;
}
return false;
});
});
This cancels the submit event if the user tries to submit the form multiple times (by clicking a submit button, pressing Enter, etc.)

I have been using blockUI to avoid browser incompatibilies on disabled or hidden buttons.
http://malsup.com/jquery/block/#element
Then my buttons have a class autobutton:
$(".autobutton").click(
function(event) {
var nv = $(this).html();
var nv2 = '<span class="fa fa-circle-o-notch fa-spin" aria-hidden="true"></span> ' + nv;
$(this).html(nv2);
var form = $(this).parents('form:first');
$(this).block({ message: null });
form.submit();
});
Then a form is like that:
<form>
....
<button class="autobutton">Submit</button>
</form>

Button Code
<button id="submit" name="submit" type="submit" value="Submit">Submit</button>
Disable Button
if(When You Disable the button this Case){
$(':input[type="submit"]').prop('disabled', true);
}else{
$(':input[type="submit"]').prop('disabled', false);
}
Note: You Case may Be Multiple this time more condition may need

Easy Method:
Javascript & HTML:
$('form#id').submit(function(e){
$(this).children('input[type=submit]').attr('disabled', 'disabled');
// this is just for demonstration
e.preventDefault();
return false;
});
<!-- begin snippet: js hide: false console: true babel: false -->
<form id="id">
<input type="submit"/>
</form>
Note: works perfectly on chrome and edge.

The simplest pure javascript solution is to simply disable the button:
<form id="blah" action="foo.php" method="post" onSubmit="return checkForm();">
<button id="blahButton">Submit</button>
</form>
document.getElementById('blahButton').disabled = true ;
It works with/without onSubmit. Form stays visible, but nothing can be sumbitted.

In my case i had to put a little delay so that form submits correctly and then disable the button
$(document).on('submit','#for',function()
{
var $this = $(this);
setTimeout(function (){
$this.find(':input[type=submit]').attr('disabled', 'disabled')
},1);
});

How to have multiple submit buttons for a quiz on one page

I'm creating a language quiz and it requires multiple submit buttons on one page through which one can check their answers. Having one submit button works fine. But so far, having multiple submit buttons creates issues where one submit button, when pressed, generates two (if there are 2 questions) of the same answers under both submit buttons. So after one click you will see 4 of the same answers. And only one submit button will be disabled. See scripts below for more info.
Below you'll find the html form for 1 of the quiz questions.
<form id="formId">
<h5>1. I am strong</h5>
<p>Translate the above sentence.</p>
<input type="text" id="q1" /><br><br>
<input type="submit" class="btn btn-outline-primary" id="submitId" value="Check answer" />
</form>
Below you'll find the javascript that gives the answer when submit button is clicked.
<script>
var answers = {
"q1": ["Ik ben sterk"]
};
function markAnswers(){
$("input[type='text']").each(function(){
console.log($.inArray(this.value, answers[this.id]));
if($.inArray(this.value, answers[this.id]) === -1){
$(this).parent().append("<br>The correct answer: Ik ben sterk");
} else {
$(this).parent().append("<br><font style='color:green;'>Correct!</font>");
}
})
}
$("form").on("submit", function(e){
e.preventDefault();
markAnswers();
});
</script>
The script below is to make sure user cannot submit answer again.
<script>
var form = document.getElementById('formId');
var submitButton = document.getElementById('submitId');
form.addEventListener('submit', function() {
// Disable the submit button
submitButton.setAttribute('disabled', 'disabled');
// Change the "Submit" text
submitButton.value = 'Check answer';
}, false);
</script>
Above scripts are just for one question. If I add another question and I copy paste scripts and change the ID's to q2, formId2 and submitId2 it will not work as described earlier. What do I need to change to the scripts in order for this to work? Any suggestion is welcome. Thanks.
Your markAnswers function is looping through all inputs, that's why you're getting the answers for all of them when you click any of the buttons.
You can fix this by changing the id of the forms to be like formId1, formId2 etc., then giving that id to the markAnswers function.
Example:
function markAnswers(id) {
$(`#q${id}`).each(function () {\
if ($.inArray(this.value, answers[this.id]) === -1) {
$(this).parent().append(`<br>The correct answer: ${answers[this.id]}`);
} else {
$(this).parent().append("<br><font style='color:green;'>Correct!</font>");
}
});
}
$("form").on("submit", function (e) {
e.preventDefault();
const id = e.target.id.replace("formId", "")
markAnswers(id);
});
Additionally, you can disable the button in the same submit event as well:
$("form").on("submit", function (e) {
...
$(`#submitId${id}`).each(function () {
this.setAttribute('disabled', true);
this.value = "Check answers"
})
});
Here's a working example: Codesandbox

Change submit button text and disable it in iOs

I have this piece of js code, it works on pc (change text to 'adding...' and disables a button). But on iOs devices only form is submitted, text is not changing. Any ideas?
$(".moveToBasket").click(function() {
var form = $(this).closest('form');
var button = $(this);
button.attr('value', 'Adding...');
form.on('submit', function() {
button.prop("disabled", true);
});
});
P.S. .moveToBasket class html element is 'input type="submit"'
I had the same problem a few days ago. It seems there are other people who confirmed the bug in Safari: https://github.com/rails/jquery-ujs/issues/306
I solved it like this:
$('body').on('submit', form, function formSubmitHandler(event){
// Shadow the form to prevent infinite loop
var form = event.target;
event.preventDefault();
// If <input type="submit">
button.attr('value', 'Adding...');
// If <button>Add</button>
button.text('Adding...');
button.prop('disabled', true);
// Submit the form in a different tick
setTimeout(function() {
form.submit();
}, 10);
});
I hope it helps.
Can you send me the HTML so I can see what needs to be done,
If it's a button element, you can do button.text('adding...')

Submit form with two submit buttons, each performing different actions issue

I have a JSP page, which has standard form on it. I have two buttons, each perform a different action when pressed, and the form is submitted - action 1 and action 2.
I originally had this set up for one button, so it was all done through the following and worked fine:
$('#form').submit( function() { .... }
But now I have two buttons, I want it to do the same, but how to find which button I pressed.
I could do this through the .click function, but I dont want to break my existing form.submit functionality.
Below is my code for this - which doesn't work:
$('#form').submit( function() {
// Set the field array variables with data
$('button[name="action1"], [name="action2"]').each(function(index) {
alert('index : ' + index );
alert('value : ' + this.value);
});
$('button[name="action1"]').click(function(e) {
alert('ac1 clicked');
});
$('button[name="action2"]').click(function(e) {
alert('ac2 clicked');
});
my html buttons are:
<button id="submitButton" name="action1" value="action1" type="submit">action 1</button>
<button id="submitButton" name="action2" value="action2" type="submit">action 2</button>
Is there a way I can do this inside my form.submit, or a way to do the .click, which then submits the form. I am a little lost for a solution on this?
Please help :)
You can read the related target of the event object.
$('#form').on('submit', function(evt) {
if (evt.relatedTarget && $(relEl).is('input[type=submit]')) {
/* related element is a button - do something */
}
evt.preventDefault(); //cancel form submit, as required
});
In the button's click handler, set a hidden field before submitting the form. Then read the value of that hidden field in the request handler to find out which action was requested.
Bind a event handler to your buttons
$('button').on('click', function(e) {
var buttonId = $(this).attr('name');
if(buttonId = 'action1') {
// action1 was pressed
} else {
// action2 was pressed
}
$('#form').trigger('submit'); // trigger submit of form.
e.preventDefault();
});
First of, never include two dom elements with the same id on the same page. The class attribute is for such things. Change the id's of the buttons to submitButton1 and submitButton2 respectively and then this ought to work:
$('#submitButton1').closest('#form').submit(function() {
// first button action
});
$('#submitButton2').closest('#form').submit(function() {
// second button action
});
For standard HTML form submission :
HTML:
<form method="..." action="...">
...
<input type="hidden" name="action">
<input value="action1" type="submit" value="action 1" />
<input value="action2" type="submit" value="action 2" />
...
</form>
Javascript:
$('button[type="submit"]').on('click', function() {
$("#action").val(this.value);//where "#action" selects an input field (in the same form) of type="hidden"
});
For AJAX submission, do the same but read the action field's value back into javascript in the submit handler.

Is there a way to check if a postback is in progress?

In the case that a button is clicked multiple times on a page - Is there a way to figure out using javascript/jquery that a postback is already in progress and cancels the new attempt to submit the page?
Thanks
You can avoid users from double clicking by disabling whatever form elements can cause a form submit.
Checkout http://greatwebguy.com/programming/dom/prevent-double-submit-with-jquery/ for an example.
You can disable the button on first click, so that you could not click it when the post is in progress, and re enable it when the post-back has finished.
<script type="text/javascript" language="JavaScript">
var submitted = false;
function SubmitTheForm() {
if(submitted == true) { return; }
document.myform.submit();
document.myform.mybutton.value = 'Thank You!';
document.myform.mybutton.disabled = true;
submitted = true;
}
</script>
<form method="post" action="#">
<input type="submit" onclick=return SubmitTheForm()>
</form>
you could always just disable the button in the onclick handler.
$('input[type="submit"]').click(function(e) {
e.preventDefault();
var self = this;
$(self).attr('disabled', 'disabled');
$.post('url',$(self).closest('form').serialize(), function() {
$(self).removeAttr('disabled'); // re-enable after request complete.
});
});
You could have your click event set a variable in your click handler to true and only allow the handler to proceed when the value is false. Of course you will have to set it to false again when your callback finishes.
if (!processInProgress) {
processInProgress = 1
// start the process
}

properly disabling the submit button

this is the code that I use to disable the button
$("#btnSubmit").attr('disabled', 'disabled')
$("#btnSubmit").disabled = true;
and this is my submit button
<input id="btnSubmit" class="grayButtonBlueText" type="submit" value="Submit" />
the button although looks disabled, you can still click on it.. This is tested with FF 3.0 and IE6
Am I doing something wrong here?
If it's a real form, ie not javascript event handled, this should work.
If you're handling the button with an onClick event, you'll find it probably still triggers. If you are doing that, you'll do better just to set a variable in your JS like buttonDisabled and check that var when you handle the onClick event.
Otherwise try
$(yourButton).attr("disabled", "true");
And if after all of that, you're still getting nowhere, you can manually "break" the button using jquery (this is getting serious now):
$(submitButton).click(function(ev) {
ev.stopPropagation();
ev.preventDefault();
});
That should stop the button acting like a button.
Depending on how the form submission is handled you might also need to remove any click handlers and/or add one that aborts the submission.
$('#btnSubmit').unbind('click').click( function() { return false; } );
You'd have to add the click handler's again when (if) you re-enable the button.
You need to process Back/Prev button into browser.
Example bellow
1) Create form.js:
(function($) {
$.enhanceFormsBehaviour = function() {
$('form').enhanceBehaviour();
}
$.fn.enhanceBehaviour = function() {
return this.each(function() {
var submits = $(this).find(':submit');
submits.click(function() {
var hidden = document.createElement('input');
hidden.type = 'hidden';
hidden.name = this.name;
hidden.value = this.value;
this.parentNode.insertBefore(hidden, this)
});
$(this).submit(function() {
submits.attr("disabled", "disabled");
});
$(window).unload(function() {
submits.removeAttr("disabled");
})
});
}
})(jQuery);
2) Add to your HTML:
<script type="text/javascript">
$(document).ready(function(){
$('#contact_frm ).enhanceBehaviour();
});
</script>
<form id="contact_frm" method="post" action="/contact">
<input type="submit" value="Send" name="doSend" />
</form>
Done :)
