Multiple jquery. Datatable coexisting a quick solution for checkbox to select all exceptions

[reasons for the problem]

This should be a bug in the jquery.datatable control itself. The id of the checkbox widget in this control is dead, so when there are multiple datatables referenced to a page, the select event matches all datatables, causing all checkboxes for multiple tables to be selected.

[solution]

So it's best to modify the jquery.datatable control to assign a different id to the checkbox under each datatable generated. Since the datatable's id is not the same, you can prefix the datatable's id with a unique id for the checkbox.   The specific checkbox call event also needs to be synchronously replaced with the new id to make the event call.

$("#"+options.select_table).find('thead tr th:first-child')
         .prepend('<input type="checkbox" value="CHK_ALL" id="'+options.select_table+'_chk_all" />');

$("#chk_all").click(function(){
==>
$("#"+$.fn.datatable_ext.defaults.select_table+"_chk_all").click(function(){

if(checked_chk_num == curr_page_chk_num){
      $("#chk_all").attr('checked', 'checked');
     }else{
      $("#chk_all").removeAttr('checked');
     }

if(checked_chk_num == curr_page_chk_num){
      $("#"+$.fn.datatable_ext.defaults.select_table+"_chk_all").attr('checked', 'checked');
     }else{
      $("#"+$.fn.datatable_ext.defaults.select_table+"_chk_all").removeAttr('checked');
