Checkbox on change event is not working on Safari

Thanks in advance for the help on this. I have a special requirement on my page where I needed a checkbox to "act" like a radio button, so only one can be checked at a time. To achieve that I used this snippet below"
<script>
$('input:checkbox').on('change', function() {
$('input:checked').not($(this)).closest('.w-checkbox').click();
});
</script>
It works perfectly on Chrome. However, it doesn't work on Safari and allows more than one checkbox to be clicked. I was wondering if anyone had ideas on how to solve this because I have tried many alternatives and unfortunately need to have the checkbox

The proper way to uncheck a checkbox is by changing the checked property.
$('input:checkbox.w-checkbox').change(function() {
$('input:checkbox.w-checkbox').not(this).prop('checked', false);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" class="w-checkbox" />
<input type="checkbox" class="w-checkbox" />
<input type="checkbox" class="w-checkbox" />

Having trouble using jQuery change() with checkboxes

I'm trying to add/remove a class and attribute to a few labels and input boxes depending on whether or not a checkbox is checked or not.
By default my check box is set up to be not checked. Here is my existing code...
$("#built").change(function()
{
$("label.readonly").removeClass("readonly");
$("input.readonly").removeAttr("readonly");
}).change();
For some reason the event isn't firing. What am I doing wrong? Thanks!
Update:
Here is my html code
<label for="address1" class="readonly">Address Line 1</label>
<input type="text" name="address1" class="readonly" readonly="readonly" value="" />
Also, upon the check box being unchecked I would like the labels and inputs to revert back to its original state of having the readonly class and attribute respectively.

Remove the .change() after the function and add a ;.
eg:
$("#built").change(function(){
$("label.readonly").removeClass("readonly");
$("input.readonly").removeAttr("readonly");
});

There is no reason your code won't work, maybe just indentation or something like this.
Here is a jsfiddle with your function and it's working.
I just removed the line break like this:
$("#build").change(function() {
$("label.readonly").removeClass("readonly");
$("input.readonly").removeAttr("readonly");
});
Maybe there are other javascript problems somewhere else in the page?

Reload div at checkbox click

Is it possible for me to reload a div when a checkbox in the same document is clicked?
<html:checkbox property="checkbox" styleId="checkbox">
<div id="divToBeRefreshed">
//content
</div>
I'd rather do it using pure javascript but ajax is ok too if there isn't another solution.

Well the answer by #karthick is for change event it will reload the content if the checkbox is unchecked also you can use the below code
$('#checkbox').change(function(){
if($(this).is(':checked')){
// Checkbox is checked.
$("#divToBeRefreshed").html('your content');
}else{
// Checkbox is not checked.
}
});
make your id of checkbox is set to
id='checkbox'
Hope this help you

try this
$("#checkbox").on('change',function(){
$("#divToBeRefreshed").html('your content');
});

The change event is sent to an element when its value changes. This event is limited to <input> elements, <textarea> boxes and <select> elements. For select boxes, checkboxes, and radio buttons, the event is fired immediately when the user makes a selection with the mouse.Hope this is what u meant mate
HTML
<input type="checkbox" name="vehicle" value="Bike">I have a bike<br>
<input type="checkbox" name="vehicle" value="Car">I have a car
<div id="divToBeRefreshed">
</div>
JS
$("input[name=vehicle]").on('change',function(){
$("#divToBeRefreshed").html($(this).val());
});
if you want to fire an event when a checkbox is checked / unchecked: use the below code too.
if( $(this).is(':checked') )

How can I disable the radio button once the user clicks on it
because the update() function changes the values when user clicks on radio button
if he keeps clicking like that then values change each time he clicks
or if he clicks on sibling radio button
so please can anyone tell me how to disable radio button
once user clicks on it
like for instance in match1
if user selects teamA radio button then i want to disable both teamA and teamB radio buttons
same for match2 if he clicks then disable the clciked radio and sibling radio aswell
Thanks for reading this can anyone help me please
I can use plain js, jquery or libraries

Use this:
$(":radio").click(function(){
var radioName = $(this).attr("name"); //Get radio name
$(":radio[name='"+radioName+"']").attr("disabled", true); //Disable all with the same name
});
What we're doing, is, when a user clicks a radio button, disable all radios with the same name.
Hope this helps.
Cheers.

Using Javascript, you can use a solution like this:
document.getElementById("IDOfButtonElement").onclick = function(){
document.getElementById("IDOfButtonElement").disabled=true;
}

jsfiddle example
http://jsfiddle.net/nhZXg/
code
$(":radio").click(function(){
$(this).attr('disabled','disabled');
});
this is the general way of doing it.
jQuery("input:radio").attr('disabled',true);
or
jQuery("input:radio").attr('disabled','disabled');

Try this:
this.setAttribute('disabled','disabled');
I suggest you to add label tag around your inputs. It cause when user clicks on the text radio button changes.
<label>teamA <input type="radio" name="match1" onclick="update('ab');" /></label>

onclick="update('ad', this);"
function onclick(word, element){
$(element).attr('disabled', 'disabled');
}

HTML checkbox onclick called in Javascript

I am having a bit of trouble trying to figure out how to get a certain part of my code to work.
<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All" onclick="selectAll(document.wizard_form, this);">
<label for="check_all_1" onclick="toggleCheckbox('check_all_1'); return false;">Select All</label>
This is my HTML which works as it should (clicking the text will click the box). The javascript for it is pretty simple:
function toggleCheckbox(id) {
document.getElementById(id).checked = !document.getElementById(id).checked;
}
However I want the onclick to happen for the input when the label is what makes the checkbox to be clicked. At this current time the onClick js does not go. What is one suggestion on how to do this?
I tried to add the onclick of the input to the onclick of the label but that doesn't work.
Any suggestions/solutions would be wonderful.

How about putting the checkbox into the label, making the label automatically "click sensitive" for the check box, and giving the checkbox a onchange event?
<label ..... ><input type="checkbox" onchange="toggleCheckbox(this)" .....>
function toggleCheckbox(element)
{
element.checked = !element.checked;
}
This will additionally catch users using a keyboard to toggle the check box, something onclick would not.

Label without an onclick will behave as you would expect. It changes the input. What you relly want is to execute selectAll() when you click on a label, right?
Then only add select all to the label onclick. Or wrap the input into the the label and assign onclick only for the label
<label for="check_all_1" onclick="selectAll(document.wizard_form, this);">
<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All">
Select All
</label>

You can also extract the event code from the HTML, like this :
<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All" />
<label for="check_all_1">Select All</label>
<script>
function selectAll(frmElement, chkElement) {
// ...
}
document.getElementById("check_all_1").onclick = function() {
selectAll(document.wizard_form, this);
}
</script>

jQuery has a function that can do this:
include the following script in your head:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js"></script>
(or just download the jQuery.js file online and include it locally)
use this script to toggle the check box when the input is clicked:
var toggle = false;
$("#INPUTNAMEHERE").click(function() {
$("input[type=checkbox]").attr("checked",!toggle);
toggle = !toggle;
});
That should do what you want if I understood what you were trying to do.
