[Solved] How to check first 200 chekboxes , then next 200 and so on?

by


This is the working eg of first 3 and next 3 check boxes, but as suggestion please don’t have these many check boxes, the user experience is very bad in this case. 

 $(document).ready(function() {
       var $cbs = $('input:checkbox'),
           $links = $("a"); 

       $links.click(function() {
          var start = $links.index(this) * 3,
              end = start + 3;
              $cbs.slice(start,end).prop("checked",true);
       });
    });

<a href=#>Check 4-7</a>
