How to Select / Deselect All Checkboxes using jQuery

if you are newbie developer and looking for a quick jQuery snippet that selects and deselects multiple checkboxes by clicking “Select All” checkbox (exactly like in Gmail), here’s one that might be useful for your HTML form. I’ve used this one in various occasions and it has proved to be very consistent every time.

As you can see in the picture below, we have multiple checkboxes, and we want toggle the select state of checkboxes when we click “Select All” box.




JS


$(document).ready(function() {
$('#selecctall').click(function(event) { //on click
if(this.checked) { // check select status
$('.checkbox1').each(function() { //loop through each checkbox
this.checked = true; //select all checkboxes with class "checkbox1"
});
}else{
$('.checkbox1').each(function() { //loop through each checkbox
this.checked = false; //deselect all checkboxes with class "checkbox1"
});
}
});

});


$(document).ready(function(){
$("#selecctall").change(function(){
$(".checkbox1").prop('checked', $(this).prop("checked"));
});
});

HTML


<ul class="chk-container">
<li><input type="checkbox" id="selecctall"/> Selecct All</li>
<li><input class="checkbox1" type="checkbox" name="check[]" value="item1"> This is Item 1</li>
<li><input class="checkbox1" type="checkbox" name="check[]" value="item2"> This is Item 2</li>
<li><input class="checkbox1" type="checkbox" name="check[]" value="item3"> This is Item 3</li>
<li><input class="checkbox1" type="checkbox" name="check[]" value="item4"> This is Item 4</li>
<li><input class="checkbox1" type="checkbox" name="check[]" value="item5"> This is Item 5</li>
<li><input class="checkbox1" type="checkbox" name="check[]" value="item6"> This is Item 6</li>
<li><input class="checkbox2" type="checkbox" name="check[]" value="item6"> Do not select this</li>
</ul>
