问题描述

MSDN上有一篇描述本机xmlhttp的文章.

MSDN has an article that describes native xmlhttp.

http://msdn.microsoft .com/en-us/library/ms537505(v = vs.85).aspx#_id

如本文所述，我已启用本机xml http.但是，这个xml演示仍然无法在我的本地服务器上运行.它在原始站点上运行.如果我将其下载到本地Web服务器，则不会. xmlhttp请求

As the article describes, I have enabled native xml http. But this xml demo still doesn't run on my local server. It runs on the original site. If I download it to the local web server, it doesn't. The xmlhttp request 

xmlhttp=new XMLHttpRequest();

不返回对象.

该演示来自w3schools网站 http://www.w3schools.com /xml/tryit.asp?filename=tryxml_app_first .

The demo is from the w3schools site http://www.w3schools.com/xml/tryit.asp?filename=tryxml_app_first.

这是HTML.

<html>
<head>

<script type="text/javascript">
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.open("GET","cd_catalog.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML; 

x=xmlDoc.getElementsByTagName("CD");
//i=0;

function displayCD(i)
{
artist=(x[i].getElementsByTagName("ARTIST")[0].childNodes[0].nodeValue);
title=(x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue);
year=(x[i].getElementsByTagName("YEAR")[0].childNodes[0].nodeValue);
txt="Artist: " + artist + "<br />Title: " + title + "<br />Year: "+ year;
document.getElementById("showCD").innerHTML=txt;
}
</script>
</head>
<body onload="displayCD(11)">

<div id='showCD'></div>

在哪里发生导致该演示无法运行的安全问题?

Where do the security issues happen that cause this demo to not run?

推荐答案

问题是我试图使用xmlhttprequest打开的xml文件中的格式.当我删除文件中的-时，它起作用了.这是与XML一起使用的HTML.

The problem was the formatting in the xml file that I was trying to open with the xmlhttprequest. When I removed the - in the file, it worked. Here is the HTML that worked along with the XML.

HTML文件.

  }
xmlhttp.open("GET","cd_catalog.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML; 

x=xmlDoc.getElementsByTagName("CD");
