Hi,

I have a dynamic jquery data table which has check boxes it. when a check box is checked at header all the check boxes in rows are also checked. i have some rows which are disabled. when the check all option is checked i don't want the disabled checkbox to be checked. Below is the code to check and uncheck all the textboxes

What I have tried:

function CheckUncheckAll() {
         $("#table thead ").on("click", 'input[type="checkbox"]', function () {
             if (!this.disabled) {
                 $('#table tbody chktransid').prop("checked", false);
             }
             if (this.checked) {

                 $('#table tbody input[type="checkbox"]').prop("checked", true);
             } else {
                 $('#table tbody input[type="checkbox"]').removeAttr("checked");
             }
         });
