Today, We will let you know how to check & uncheck a checkbox with jQuery in this article. I see many peoples are confused about How to Check a Checkbox is Checked or Not using jquery. so I have created this article and share in our website. there is a three-way to check which checkbox is checked.
The three ways are as follows with an example.

checkbox name wise checked value
|
1 2 3 4 5 6 7 8 9 10 |
$('input[name="chk1"]').click(function(){ //checked var chk_color = $(this).val(); var check = $(this).prop("checked"); if(check) { alert(chk_color+" Checkbox is checked."); } else { alert(chk_color+" Checkbox is unchecked."); } }); |
checkbox class name wise checkbox checked value
|
1 2 3 4 5 6 7 8 9 10 |
$('.chk2').click(function(){ //checked var chk_color = $(this).val(); var check = $(this).prop("checked"); if(check) { alert(chk_color+" Checkbox is checked."); } else { alert(chk_color+" Checkbox is unchecked."); } }); |
function name wise checkbox checked value
|

function funchk3(value) { var check = $('.chk3').prop("checked"); if(check) { alert(value+" Checkbox is checked."); } else { alert(value+" Checkbox is unchecked."); } } |
