selecting all checkboxes in jquery -

i want select checkboxes of specific name checking single checkbox on page , trigger subsequent events.

as have @ moment doesnt seem fire immediately, upon first checking of 'select all' checkbox checkboxes not selected , unchecking 'select all' check box checkboxes checked.

seems bit upside down.

how can improve following code works properly?

$(document).on("click", "input[name='chkallbs']", function () {  if ($('input[name = chkbestseller]').prop('checked') == false) {     $('input[name=chkbestseller]').attr("checked", "true");     $('input[name=chkbestseller]').trigger('click'); } else {     $('input[name=chkbestseller]').attr("checked", "false");     $('input[name=chkbestseller]').trigger('click'); } 

it like

if ($('input[name = chkbestseller]').prop('checked') == true) {      $('input[name=chkbestseller]').attr("checked", true); } else {      $('input[name=chkbestseller]').attr("checked", false); } 

or

$(document).on("click", "input[name='chkallbs']", function () {     $('input[name="chkbestseller"]').prop("checked", this.checked); });
