I have a simple bit of jquery which is running a trigger on click of a radio button to check my check boxes.
<script>
jQuery('#op5').click(function () {
$('input[type=checkbox]').trigger('click');
});
</script>
These are my checkboxes they have labels to give them a custom style.
<input type="checkbox" certificate="true" checked="checked" id="gridcb0" siteid="1381" value="72218" class="custom selector checkedFocus">
<label for="gridcb0" class="white"> </label>
And this is the radio button I am clicking to check the checkboxes
<input type="radio" id="op5" value="1" name="options2" class="custom">
However it is not checking my check boxes on first click it requires me to click on the radio button op5 twice to check the boxes, I do not want to run the line below twice to highlight these check boxes
<input type="radio" id="op5" value="1" name="options2" class="custom">
Suggestions?
Use .prop() property and add value checked instead of trigger click
If you are using jQuery 1.6+
jQuery('#op5').click(function () {
$('input[type=checkbox]').prop('checked', true);
});
Docs: https://api.jquery.com/prop/
try below code
jQuery('#op5').click(function () {
$('input[type=checkbox]').attr('checked', true);
});
Which version of jQuery you are using
For jQuery 1.6+, Use the new .prop() function and for jQuery 1.5.x and below, use .attr() function
// jQuery 1.6+
$('#op5').click(function () {
$('#gridcb0').prop('checked', true);
});
// jQuery 1.5.x and below
$('#op5').click(function () {
$('#gridcb0').attr('checked', true);
});
Check this post for more details -
Setting "checked" for a checkbox with jQuery?
Try prop() and trigger():
Since you have id, you can use id selector
$('#gridcb0').prop('checked', true).trigger('click');
If you still want to target all checkbox:
$('input[type=checkbox]').prop('checked', true).trigger('click');

Quick question. Can anyone tell me why this function is working backwards? For example, when I check it, it unchecks all of my checkboxes and when I uncheck it, it checks all of checkboxes.
The function was working fine until I added the .click() method at the end. However I need this so that the boxes call the function when clicked. Any help is appreciated!
Jquery:
$("#checkAll").click(function () {
$('input:checkbox').not(this).prop('checked', this.checked).click();
});
HTML Master Checkbox:
<div id="masterButton">
<input type="checkbox" id="checkAll" checked>Check/UnCheck All<br>
</div>
HTML All other checkboxes:
<input id="bus0" type="checkbox" value="0">
You want to click all the checkboxes that are not checked the same as your primary checkbox. So just add a ! and you're fine:
$("#checkAll").click(function () {
$('input:checkbox').not(this).prop('checked', !this.checked).click();
});
the question is too difficult for me:
I have two button:
#Inca
and
#Maya
If #Inca checked, i want disabled #Inca and to remove (if there is) the check on button #Maya .
But than, if i check #Maya, i want disabled #Maya, abled #Inca but to remove the check on button #Inca (but this doesn't work).
In this way if i want, i can check button #Inca and the "loop" start again.
This is the code:
$('#incas, #maya').change(function () {
if ($('#incas').attr("checked")) {
$('#incas').attr('disabled', true);
$('#maya').attr('disabled', false);
}
if ($('#maya').attr("checked")){
$('#maya').attr('disabled', true);
$('#incas').attr('disabled', false);
$('#incas').attr('checked', false);
}
});
and this is jsfiddle:

You should not use checkboxes in this case. Use radio buttons and you won't need any JS:
<div id="noneAbove">
<p>
<input id="inca" name="foo" type="radio" />
inca </p>
<p>
<input id="support" name="foo" type="radio" />Blah Blah</p>
</div>
Use class to enable and disable buttons: less code, more efficient and clean.
using single style class for enabled and disabled button
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') )

i want to select a checkbox when a button is clicked.
<form action="" method="post" id="form2">
<input type="checkbox" id="checkone" value="one" name="one" />
<input type="button" value="Click me" id="buttonone"/>
</form>
when i tried the following, the checkbox was not getting selected
$('#buttonone').click(function() {
$('#checkone').checked=true;
});
then i tried:
$('#buttonone').click(function() {
document.getElementById('checkone').checked=true;
});
this time the checkbox got selected. why isn't it getting selected with the jquery $ function?
Try
$('#checkone').attr('checked', true);
or
$('#checkone').get(0).checked = true;
or
$('#checkone')[0].checked = true; // identical to second example
The reason your first code didn't work is because you were trying to set the checked property on a jQuery object which will have no visible effect as it only works on the native DOM object.
By calling get(0) or accessing the first item [0], we retrieve the native DOM element and can use it normally as in your second example. Alternatively, set the checked attribute using jQuery's attr function which should work too.
You need to use .attr() for the jQuery object, like this:
$('#buttonone').click(function() {
$('#checkone').attr('checked', true);
});
But it's better to do it the DOM way, like this:
$('#buttonone').click(function() {
$('#checkone')[0].checked = true; //get the DOM element, .checked is on that
});
Or, completely without jQuery:
document.getElementById('buttonone').onclick = function() {
document.getElementById('checkone').checked = true;
};
None of these answers worked for me because I incorrectly had multiple radios with the same name attributes:
<div id="group-one">
<input type="radio" name="groups" value="1" checked="checked" />
<input type="radio" name="groups" value="2" />
</div>
<div id="group-two">
<input type="radio" name="groups" value="1" checked="checked" />
<input type="radio" name="groups" value="2" />
</div>
Javascript won't recognize the checked attribute (obviously). This was a result of using include to add a similar section of HTML multiple times. Obviously, clicking on a radio button will uncheck the radio toggles with the same name.
Here's a jsfiddle to show that two radio elements can have the attribute checked but only the last one is actually checked:
http://jsfiddle.net/bozdoz/5ecq8/
Again, pretty obvious, but possibly something to watch out for: remove id and name attributes from files that you intend to include into other files multiple times.
Try
$('#checkone').attr('checked', true);
You don't have direct access to DOM object properties because jQuery operates on collections ($(selector) is an array). That's why you have functions defined to manipulate the contents of the returned elements.
try
$('#checkone').attr('checked', true);
cleary googling for "jquery check a checkbox" was the way to go
Or you could simply do
$('#buttonone').click(function() {
$('#checkone')[0].checked=true;
});
It is because ".checked" is not part of jQuery and you are trying to use it on a jQuery object. If you index a jQuery object at [0] you get the raw Javascript object which ".checked" exists on.
More here: http://phrappe.com/javascript/convert-a-jquery-object-to-raw-dom-object/
try this
$('#buttonone').click(function() {
$('#checkone').prop('checked', true);
});
I have 3 radio buttons in my web page, like below:
<label for="theme-grey">
<input type="radio" id="theme-grey" name="theme" value="grey" />Grey</label>
<label for="theme-pink">
<input type="radio" id="theme-pink" name="theme" value="pink" />Pink</label>
<label for="theme-green">
<input type="radio" id="theme-green" name="theme" value="green" />Green</label>
In jQuery, I want to get the value of the selected radio button when any of these three are clicked. In jQuery we have id (#) and class (.) selectors, but what if I want to find a radio button by its name, as below?
$("<radiobutton name attribute>").click(function(){});
Please tell me how to solve this problem.
This should do it, all of this is in the documentation, which has a very similar example to this:
$("input[type='radio'][name='theme']").click(function() {
var value = $(this).val();
});
I should also note you have multiple identical IDs in that snippet. This is invalid HTML. Use classes to group set of elements, not IDs, as they should be unique.
To determine which radio button is checked, try this:
$('input:radio[name=theme]').click(function() {
var val = $('input:radio[name=theme]:checked').val();
});
The event will be caught for all of the radio buttons in the group and the value of the selected button will be placed in val.
Update: After posting I decided that Paolo's answer above is better, since it uses one less DOM traversal. I am letting this answer stand since it shows how to get the selected element in a way that is cross-browser compatible.
$('input:radio[name=theme]:checked').val();
another way
$('input:radio[name=theme]').filter(":checked").val()
This works great for me. For example you have two radio buttons with the same "name", and you just wanted to get the value of the checked one. You may try this one.
$valueOfTheCheckedRadio = $('[name=radioName]:checked').val();
The following code is used to get the selected radio button value by name
jQuery("input:radio[name=theme]:checked").val();
Thanks

For anyone who doesn't want to include a library to do something really simple:
document.querySelector('[name="theme"]:checked').value;

For a performance overview of the current answers check here
I found this question as I was researching an error after I upgraded from 1.7.2 of jQuery to 1.8.2. I'm adding my answer because there has been a change in jQuery 1.8 and higher that changes how this question is answered now.
With jQuery 1.8 they have deprecated the pseudo-selectors like :radio, :checkbox, :text.
To do the above now just replace the :radio with [type=radio].
So your answer now becomes for all versions of jQuery 1.8 and above:
$("input[type=radio][name=theme]").click(function() {
var value = $(this).val();
});
You can read about the change on the 1.8 readme and the ticket specific for this change as well as a understand why on the :radio selector page under the Additional Information section.
If you'd like to know the value of the default selected radio button before a click event, try this:
alert($("input:radio:checked").val());
You can use filter function if you have more than one radio group on the page, as below
$('input[type=radio]').change(function(){
var value = $(this).filter(':checked' ).val();
alert(value);
});
Here is fiddle url
http://jsfiddle.net/h6ye7/67/
<input type="radio" name="ans3" value="help">
<input type="radio" name="ans3" value="help1">
<input type="radio" name="ans3" value="help2">
<input type="radio" name="ans2" value="test">
<input type="radio" name="ans2" value="test1">
<input type="radio" name="ans2" value="test2">
<script type="text/javascript">
var ans3 = jq("input[name='ans3']:checked").val()
var ans2 = jq("input[name='ans2']:checked").val()
</script>
If you want a true/false value, use this:
$("input:radio[name=theme]").is(":checked")
Something like this maybe?
$("input:radio[name=theme]").click(function() {
...
});
When you click on any radio button, I believe it will end up selected, so this is going to be called for the selected radio button.
I you have more than one group of radio buttons on the same page you can also try this to get the value of radio button:
$("input:radio[type=radio]").click(function() {
var value = $(this).val();
alert(value);
});
Cheers!
can also use a CSS class to define the range of radio buttons and then use the following to determine the value
$('.radio_check:checked').val()
This worked for me..
HTML:
<input type="radio" class="radioClass" name="radioName" value="1" />Test<br/>
<input type="radio" class="radioClass" name="radioName" value="2" />Practice<br/>
<input type="radio" class="radioClass" name="radioName" value="3" />Both<br/>
Jquery:
$(".radioClass").each(function() {
if($(this).is(':checked'))
alert($(this).val());
});
Hope it helps..
$('input:radio[name=theme]').bind(
'click',
function(){
$(this).val();
});
You might notice using class selector to get value of ASP.NET RadioButton controls is always empty and here is the reason.
You create RadioButton control in ASP.NET as below:
<asp:RadioButton runat="server" ID="rbSingle" GroupName="Type" CssClass="radios" Text="Single" />
<asp:RadioButton runat="server" ID="rbDouble" GroupName="Type" CssClass="radios" Text="Double" />
<asp:RadioButton runat="server" ID="rbTriple" GroupName="Type" CssClass="radios" Text="Triple" />
And ASP.NET renders following HTML for your RadioButton
<span class="radios"><input id="Content_rbSingle" type="radio" name="ctl00$Content$Type" value="rbSingle" /><label for="Content_rbSingle">Single</label></span>
<span class="radios"><input id="Content_rbDouble" type="radio" name="ctl00$Content$Type" value="rbDouble" /><label for="Content_rbDouble">Double</label></span>
<span class="radios"><input id="Content_rbTriple" type="radio" name="ctl00$Content$Type" value="rbTriple" /><label for="Content_rbTriple">Triple</label></span>
For ASP.NET we don't want to use RadioButton control name or id because they can change for any reason out of user's hand (change in container name, form name, usercontrol name, ...) as you can see in code above.
The only remaining feasible way to get the value of the RadioButton using jQuery is using css class as mentioned in this answer to a totally unrelated question as following
$('span.radios input:radio').click(function() {
var value = $(this).val();
});
