在你的servlet输出中加上js代码啊.
String Msg="<script>";
Msg+="var control=parent.getElementById('xxxx');"//获取你要操作的控件
Msg+="control=xxxxxxx";//操作你的控件
Msg+="</script>";
out.write(Msg);
String Msg="<script>";
Msg+="var control=parent.getElementById('xxxx');"//获取你要操作的控件
Msg+="control=xxxxxxx";//操作你的控件
Msg+="</script>";
out.write(Msg);

写个servlet页面:SentOk.java
package com.test;import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;public class SentOk extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=GBK"; //Initialize global variables
public void init() throws ServletException {
} //Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head><title>SentOk</title></head>");
out.println("<body bgcolor=\"#ffffff\">");
out.println("<p>The servlet has received a " + request.getMethod() + ". This is the reply.</p>");
out.println("ok!");
out.println("</body></html>");
} //Process the HTTP Post request
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doGet(request, response);
} //Clean up resources
public void destroy() {
