             $('#inputCheck').click(function () {
                 if ($(this).attr("checked")) {//全选
                     $("input[name='chkSelect']").attr("checked", $(this).attr("checked"));
                     $("#selectAll").text("取消全选");
                 } else {
                     $('table input[type=checkbox]').attr('checked', false);
                     $("#selectAll").text("全选");
                 }
             });
         });
