simpleResponse.xml 文件里面要怎么写 ？为什么警告框跳不出来？
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><script type="text/javascript">var xmlHttp;function createXMLHttpRequest()
{ if(window.ActiveXObject)
{
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
} else if(window.XMLHttpRequest)
{
xmlHttp = new XMLHttpRequest();
}
}function startRequest()
{ createXMLHttpRequest();
xmlHttp.onreadystatechange = handleStateChange;
xmlHttp.open("GET","simpleResponse.xml",true);
xmlHttp.send(null);
}function handleStateChange()
{ if(xmlHttp.readyState == 4)
{ if(xmlHttp.state == 200)
{ alert("The server replied with: " + xmlHttp.responseText);
}
}
}</script></head><body>
<form action="#">
<input type="button" value="Start Basic Asynchronous Request" onclick="startRequest()" />
</form></body></html>

simpleResponse.xml 这个文件在你测试的时候可以随便写点内容进去，比如"hello world!"；但真正的xml文件格式应该是像这样的<?xml version="1.0" encoding="ISO-8859-1"?><!-- Copyright w3school.com.cn --><note> <to>George</to> <from>John</from> <heading>Reminder</heading> <body>Don't forget the meeting!</body></note>
