变量定义:

    <%
        String ipsearch = "";
        String unitsearch = " ";
        String postsearch = " ";
        String privilegesearch = " ";
        ipsearch = request.getParameter("ipsearch");
        unitsearch = getStrCN(request.getParameter("unitsearch"));
        postsearch = request.getParameter("postsearch");
        privilegesearch = request.getParameter("privilegesearch");
    %>

表单:

  <form name="input" action="yh5ip_test.jsp" method="get">
	 <div align="left">I  P    :  
	   <input type="text" name="ipsearch" value = <%=ipsearch%> />
	   </br>
	单位:
	<input type="text" name="unitsearch" value = <%=unitsearch%> />
	</br>
	岗位:
	<input type="text" name="postsearch" value = <%=postsearch%> />
	</br>
	权限:
	<input type="text" name="privilegesearch" value = <%=privilegesearch%> />
	<input type="submit" value="查询" />
	 </div>
   </form>

另一种方法是用JavaScript:

变量定义:

<%
try{
  ResultSet Rs1=null;
  String jd = request.getParameter("jd");
  if(jd == null){
	jd = "ip";
  }
%>

表单:

<form  name="form1" method="post"  action="yh5ip_test.jsp">
   <h2><b>排序字段:</b>
		<select name="jd"  onChange="auto_sub()">
			<option value="ip" <%if(jd != null && jd.equals("ip")){%>selected<%}%>>IP</option>
            <option value="unit" <%if(jd != null && jd.equals("unit")){%>selected<%}%>>单位</option>
			<option value="post" <%if(jd != null && jd.equals("post")){%>selected<%}%>>岗位</option>
			<option value="privilege" <%if(jd != null && jd.equals("privilege")){%>selected<%}%>>权限</option>
		</select></h2>
		<br>

JavaScript:

<SCRIPT>
   void function  auto_sub(){
  //保存到数据库
	//DCellWeb1.SaveFile();
	form1.action = "yh5ip_test.jsp";
    form1.submit();
  }
</SCRIPT>

注意: 一个是提交的页面名称,还有一个是浏览器版本,IE8就行,不然会出现点了没反应的情况
