新人弱弱的问下局部刷新问题~~

假设有A.htm、B.htm两页,A.htm:
<div id=aaa></div><iframe width=0 height=0src=b.htm></iframe>
B.htm：
<script>parent.aaa.innerHTML='test!'</script>那我如何在A页面刷新B页面呢？

给你的iframe定义一个namedocument.frames('ifrmname').location.reload()
document.all.ifrmname.document.location.reload()定义一个ID
ifrmid.window.location.reload()
谢谢这个方法不错~~但是还有个问题~~我发现这样点击刷新还是全页面刷新额~~为什么不是局部刷新的？<tr>
                        <td width="100">用户名</td>
                        <td width="150"><input type="text" name="username" id="username" size="20"></td>
                    </tr>
                    <tr>
                        <td>密码</td>
                        <td><input type="password" name="password" id="password" size="21"></td>
                    </tr>
                    <tr>
                        <td>验证码</td>
                        <td><input type="text" id="Verification" name="Verification" value="" size="2">&nbsp<span id="VerCode"></span><iframe width=0 height=0 id="vc" name="vc" src=image.jsp></iframe></br><a href=""  onclick="reload()">换一张</a></td>
                    </tr>
                    <tr>
                        <td colspan="2" align="center"><input type="submit" value="登陆"><input type="reset" value="重置"></td>
                    </tr>image页面：
<script language="JavaScript">
function reloadcode(){
parent.VerCode.innerHTML = "<input type=\"image\" src=\"VerficationServlet\" disabled>";
}
</script>
  </head>

  <body onload="reloadcode()">

  </body>
ajax,或者jquery解决吧，很简单的。
ajax不太清楚如何传图片出来~~~
在子页面里通过js往父页面传递图片的path，在父页面里顶一个隐藏域来接收这个对应的路径，这样就能是实现图片浏览了  <c:if test="${!empty(requestScope.path)}">
  <script>
  parent.document.getElementById("path").value="${requestScope.path}";
  parent.document.getElementById("view").innerHTML="<img src=\"${pageContext.request.contextPath}/${requestScope.path}\" height='200 width='200'/> "
  </script>
  </c:if>[code=text]
<tr>
<td>
图片
</td>
<td>
<iframe
src="${pageContext.request.contextPath }/upload.jsp?path=${requestScope.product.path}"
width="100%" height="25" marginheight="0" marginwidth="0"
scrolling="no" frameborder="0"></iframe>
</td>
</tr>
<tr>
<td>
浏览
</td>
<td id="view">
<c:if test="${empty(requestScope.product.path )}">
 
</c:if> <c:if test="${!empty(requestScope.product.path)}">
<img
src="${pageContext.request.contextPath }/${requestScope.product.path}"
width="200" height="200" />
</c:if> </td>
</tr>[/code]
嗯想要用ajax来实现这些，可以在js里用ajax控制啊，包括图片浏览也可以在ajax返回的data路径结果在js里直接去处理
我有点不太理解~~~~~能这样嘛~我写个简单的你看看哪里不对？有一个登陆JSP就叫A.jsp还有个图片的jsp就叫B.jsp好了
然后A页面代码：<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">

<script language="JavaScript">

  </head>

  <body>
    <table>
     <tr>
<td>验证码</td>
   <td><input type="text" id="Verification" name="Verification" value="" size="2">&nbsp<span id="VerCode"></span><iframe width=0 height=0 id="vc" name="vc" src=b.jsp></iframe></br><a href=""  onclick="reload()">换一张</a></td>
        </tr>
    </table>
  </body>
</html>然后B.jsp:<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
