jQuery - How to Check Uncheck All Checkboxes with Header Checkbox

Sep 24, 2013
Introduction

Here I will explain how to use jQuery to check uncheck all checkboxes or select or deselect all checkboxes using jQuery.


To implement this we need to write the code like as shown below


<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>jQuery Check uncheck all Checkboxes</title>
<script src="http://code.jquery.com/jquery-1.8.2.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$('input[name="chkUser"]').click(function () {
if ($('input[name="chkUser"]').length == $('input[name="chkUser"]:checked').length) {
$('input:checkbox[name="chkAll"]').attr("checked", "checked");
}
else {
$('input:checkbox[name="chkAll"]').removeAttr("checked");
}
});
$('input:checkbox[name="chkAll"]').click(function () {
var slvals = []
if ($(this).is(':checked')) {
$('input[name="chkUser"]').attr("checked", true);
}
else {
$('input[name="chkUser"]').attr("checked", false);
slvals = null;
}
});
})
</script>
<style type="text/css">
li
{
list-style-type:none;
}
</style></head>
<body>
<ul>
<li><label><input type="checkbox" name="chkAll" value="All"/>
Select All
</label></li>
<li><label><input type="checkbox" name="chkUser" value="3930"/>Suresh</label></li>
<li><label><input type="checkbox" name="chkUser" value="4049"/>Rhoini</label></li>
<li><label><input type="checkbox" name="chkUser" value="4076"/>Mahesh</label></li>
<li><label><input type="checkbox" name="chkUser" value="4086"/>Mahendra</label></li>
<li><label><input type="checkbox" name="chkUser" value="4087"/>Madhav</label></li>
<li><label><input type="checkbox" name="chkUser" value="4116"/>Honey</label></li>
<li><label><input type="checkbox" name="chkUser" value="4143"/>Sateesh</label></li>
<li><label><input type="checkbox" name="chkUser" value="4296"/>Praveen</label></li>
</ul>
</body>
</html>
Demo


Note: if you are using asp.net checkbox controls then you need to replace

$('input:checkbox[name="chkAll"]') with ('[id$= chkAll]')
