以前没有开发过JSP的程序，属于菜鸟级别，请各位大牛帮忙。
<SCRIPT language=javascript>
     function check1(form) {
         if (form.patient_id_1.value == "") {
             alert("请输入患者ID号!");
             form.patient_id_1.focus();
             return false;
         }
         form.submit();
     }
</SCRIPT>
......
  
<FORM method=POST name=form1 onsubmit="return check1(form1)" action=submit.do?action=patient_query>
<TABLE ....>
<INPUT class=btn_grey type=submit value=查询>
  
......
  
</TABLE>
</FORM>
