In jQuery, you can use attr() function to check or unchecked a checkbox dynamically. For example,
A simple checkbox component.
<input type="checkbox" name="checkme">Check Me</input>
1. To display whether this checkbox is checked or not (return true or false).
$('input:checkbox[name=checkme]').is(':checked');
2. To check a checkbox.
$('input:checkbox[name=checkme]').attr('checked',true);
3. To uncheck a checkbox.
$('input:checkbox[name=checkme]').attr('checked',false);

<head>
<title>jQuery check / uncheck a check box example</title>
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>

<body>
<h1>jQuery check / uncheck a check box example</h1>
<script type="text/javascript">
$(document).ready(function(){
$("#isCheck").click(function () {
alert($('input:checkbox[name=checkme]').is(':checked'));
});
$("#checkIt").click(function () {
$('input:checkbox[name=checkme]').attr('checked',true);
});
$("#UnCheckIt").click(function () {
$('input:checkbox[name=checkme]').attr('checked',false);
});
});
</script>
</head><body>

</body>
</html>

Really nice article. I am sharing another article which too discusses about checking and un-checking a group of checkboxes defined inside a class. But this article uses the ‘.prop()’ function instead of ‘.attr()’ function. Please check it and let us know if it has helped you.

Thanks. This only worked 1 time with .attr(), but works as in the above demo with .prop() 🙂

Hi,
This is a nice example. You can Refer this article for
“ How to check a checkbox is checked using jQuery” in different ways
With struts2 rendered check boxes it does nto work…since they are sending hidden values -checkboxes…which do not change if u have hidden and now visible checkboxes.
