问题描述
- 求助XMLHttpRequest status为0
-
本人新手，学习ajax遇到个问题XMLHttpRequest请求数据时候 status=0，responseText为空，但是偶尔又能接收到值，服务器端response status200一直正常，直接连接jsp页面又能打开。服务器端测试jsp
<%@ page contentType="text/html; charset=GB2312" import="myfirstweb1.*" %>
<%out.println(0);%>
<% testexit tt=new testexit("lqw");
out.println(0);
%>
<%out.println(0);%>
同一目录下的jsp文件正常
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

遇到了同样的问题，我的url设置的是http://www.baidu.com 返回的status一直是0，url换成本地的一个地址后就是200了。无措。。请问你的现在有解决方案了吗
解决方案四：
你那个是跨域了，具体自己百度吧，我也搞不定，我这个重新找了个模板粘贴复制了一下就好了，汗.......
