        $("#div_Student").easydrag();         $("#div_Student").setHandler("div_Student_Title");

        function chkValue(str) {             if (str.indexOf(",") != -1) {                 //第一个弹出层中的文本框获得值                                 $("#hidUID").val(str.split(",")[0]);                 $("#txtUName").val(str.split(",")[1]);                 $("#txtTTCard").val(str.split(",")[12]);                 $("#ddlDepName").val(str.split(",")[9]);                 $("#ddlClassName").val(str.split(",")[10]);                 $("#txtTeacherName").val(str.split(",")[5]);             }             $("#div_Student").hide();         }

        function setPopUpHeight(height) {             $("#iframeStudent").attr("height", height);         } </script>
