**你好我想检查uncheck复选框使用jquery我试过但当我检查主复选框时所有Sub复选框都被检查...

使用此功能：找到父tr，然后找到tr。并找到下一个tr内的所有子复选框，然后选中或取消选中它们。

<script type="text/javascript"> 

        $("input[name$='chkMain']").change(function () {
          // get all child checkbox
          var $subCheckbox = (this).closest('tr').next('tr').find("input[name$='chkSub']"); 
          // check or uncheck child
          $subCheckbox.prop('checked', $(this).prop('checked')); 
          }); 

   </script>
