In this tutorial i explains how to select and deselect multiple check box using jquery.

First you have to include a jQuery Libarary

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>

HTML Code for Check boxes

<ul class="main">
<li><input type="checkbox" id="select_all" /> Select all</li>
<ul>
<li><input type="checkbox" class="checkbox" value="1"/>Item 1</li>
<li><input type="checkbox" class="checkbox" value="2"/>Item 2</li>
<li><input type="checkbox" class="checkbox" value="3"/>Item 3</li>
<li><input type="checkbox" class="checkbox" value="4"/>Item 4</li>
<li><input type="checkbox" class="checkbox" value="5"/>Item 5</li>
</ul>
</ul>

<li><input type="checkbox" id="select_all" /> Select all</li>

<ul>

</ul>

#select_all is the id for check box and items checkboxes have a checkbox class.

Jquery Script

<script type="text/javascript">
$(document).ready(function(){
$('#select_all').on('click',function(){
if(this.checked){
$('.checkbox').each(function(){
this.checked = true;
});
}else{
$('.checkbox').each(function(){
this.checked = false;
});
}
});
$('.checkbox').on('click',function(){
if($('.checkbox:checked').length == $('.checkbox').length){
$('#select_all').prop('checked',true);
}else{
$('#select_all').prop('checked',false);
}
});
});
</script>

$(document).ready(function(){

$('#select_all').on('click',function(){

if(this.checked){

$('.checkbox').each(function(){

this.checked = true;

});

}else{

$('.checkbox').each(function(){

this.checked = false;

});

}

});

$('.checkbox').on('click',function(){

if($('.checkbox:checked').length == $('.checkbox').length){

$('#select_all').prop('checked',true);

}else{
