Let’s understand how does it work –

  • When you check a single checkbox of check all then all the checkboxes of records will be automatically checked.
  • Also, When you uncheck a single checkbox of check all then all the checkboxes of records will be automatically unchecked.
  • If you uncheck any one of the checkboxes of records then a single checkbox of check all will be unchecked automatically

1. Create HTML Checkboxes in a Table

To create HTML checkboxes, you will have to implement the following points –

  • Declare class=”checkbox-group” attribute within the <tbody> tag. remember that only checkboxes of records must be within this class and you must declare another single checkbox to check all out of this class.
  • Another single checkbox to check all must be created with id=”singleCheckbox”  attribute

Don’t forget to Also, you should include the custom.js file (It is explained in the next step) and the following jquery ajax CDN link on the page where checkboxes are created.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>

        if(this.checked){
            $(checkboxGroup).each(function(){
                this.checked = true;
            });
        }else{
             $(checkboxGroup).each(function(){

    $(checkboxGroup).on('click',function(){
        if($(checkboxGroup+':checked').length == $(checkboxGroup).length){
            $(singleCheckbox).prop('checked',true);
