struts2使用ajax

    struts版本:2.1.8.1

一.需要包(2个)

    json-lib-2.1.jar

    struts2-json-plugin-2.1.8.1.jar

二.下载js(两个)

    json.js

    prototype.js

三.配置文件中添加如下代码.

 

<struts>
	<package name="TestAjax" extends="json-default">
		<action name="TestAjax" class="com.DreamAjaxAction">
			<result type="json" />
		</action>
	</package>
</struts>

 四.创建DreamAjaxAction

package com;

import com.opensymphony.xwork2.ActionSupport;

public class DreamAjaxAction extends ActionSupport {

	private String result;

	public String getResult() {
		return result;
	}

	public void setResult(String result) {
		this.result = result;
	}

	public String execute() throws Exception {
		result = "ajax测试";
		return SUCCESS;
	}
}

 五.测试jsp

    ...

    <script src="../json.js" type="text/javascript"></script>
    <script src="../prototype.js" type="text/javascript"></script>
    <script>
        function setTest() {
           var url = "TestAjax .action";
           new Ajax.Request(url,{method: 'post',onComplete: getTest});
        }
        function getTest(originalRequest){

            document.getElementById("test").innerHTML=

                                                       originalRequest.responseText.parseJSON().result;

        }
     </script>
     <input type="button" onclick="setTest()"/>
   <span id="test"></span>

    ....
