今天在用struts2 与Ajax结合的时候不能把数据取回到页面来了。。请大家帮帮忙：

html代码：

registor form

var request;

function checkUserName(){

var username = document.getElementById('userName').value;

var url = "checkUserName.action?username="+username;

if (window.XMLHttpRequest) {

request = new XMLHttpRequest();

}else if (window.ActiveXObject) {

request = new ActiveXObject("Microsoft.XMLHTTP");

}

if(request){

request.open("GET",url, true);

request.onreadystatechange = complete;

request.send(null);

}

}

function complete(){

if (request.readyState == 4) {

if (request.status == 200) {

alert("test1");

alert(resquest.responseText);

// document.getElementById().style.display = "true";

document.getElementById("message").innerHTML = resquest.responseText;

}

}

}

Registor Here.

pswd:

后台struts的代码：

主要是execute()方法的代码：

public String execute() {

ApplicationContext ctx = new ClassPathXmlApplicationContext(

"applicationContext.xml");

UsersService userService = (UsersService) ctx.getBean("UsersService");

result = userService.checkUserName(username);

HttpServletResponse response = (HttpServletResponse) ActionContext

.getContext().get(

org.apache.struts2.StrutsStatics.HTTP_RESPONSE);

PrintWriter pw;

try {

pw = response.getWriter();

pw.write("test");

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}//获取out输出对象

return null;

}

其他配置文件都没有 action也有反映 但是在页面上不知道怎么把数据拿回来显示。
