需注意的事項(xiàng)
1、需引入struts2-dojo-plugin-2.1.8.1.jar
2、頁(yè)面標(biāo)簽的變化如下：
ajax.jsp
- <%@ page language="java" pageEncoding="UTF-8"%>
- <%@ taglib prefix="s" uri="/struts-tags"%>
- <%@ taglib prefix="sx" uri="/struts-dojo-tags"%><!-- 注意 -->
-
- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
- <html>
- <head>
- <title>Ajax Demo</title>
- <sx:head/><!-- 注意 -->
- </head>
-
- <body>
- <h1>Ajax Dmeo:</h1>
- <div id="show">一個(gè)div</div>
- <s:form namespace="/demo" action="ajax!testAjax" method="post"><!-- 注意 -->
- <s:textfield name="name"></s:textfield>
- <sx:submit value="修改上面div的值" targets="show"></sx:submit><!-- 注意 -->
- </s:form>
- </body>
- </html>
<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%@ taglib prefix="sx" uri="/struts-dojo-tags"%><!-- 注意 -->

ajaxResult.jsp:
- <%@ taglib prefix="s" uri="/struts-tags" %>
-
- <%
- request.setAttribute("decorator", "none");
- response.setHeader("Cache-Control","no-cache");
- response.setHeader("Pragma","no-cache");
- response.setDateHeader ("Expires", 0);
- System.out.println("ajaxResult.jsp is called");
- %>
-
- Result: <s:property value="data"/><br/>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%
request.setAttribute("decorator", "none");
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy server
System.out.println("ajaxResult.jsp is called");
%>
Result: <s:property value="data"/><br/>
這樣ajaxResult.jsp的內(nèi)容將會(huì)出現(xiàn)在ajax.jsp的id="show"的div中
