Check if the checkbox is checked. There are several ways to get to work out if a checkbox is checked or not with jQuery, and here a couple of alternatives. Each will return true if it's checked or false if it's not. $('input[name=foo]').is(':checked') $('input[name=foo]').attr('checked') Set the checkbox to checked or not checked If you have multiple checkbox list or in table rows then we can get all checked checkbox value in string or array in jquery. I will give you very basic example and demo so you can see how it get selected checkbox value in jquery. we will input[type=checkbox]:checked with each loop of jquery so we can get it all checked check box and we will.
