通过 XML 进行的 AJAX 在 Chrome/Firefox 中不起作用

发布于 2024-11-07 12:18:29 字数 1631 浏览 0 评论 0 原文

我有以下代码：

var xmlCurr = new ActiveXObject("Microsoft.XMLDOM");
xmlCurr.async = false;
xmlCurr.load(xmlURL);
return xmlCurr;

来自 xmlCurr 我需要以下信息

xmlCurr.xml
xmlCurr.documentElement
xmlCurr.selectSingleNode("result").text;

此代码在 IE6+ 上运行良好，但在 Chrome 或 Firefox 上不起作用。

我尝试过改编代码 http://www.w3schools.com/Xml/xml_parser.asp

获取某些内容如下：

if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
     xmlCurr=new XMLHttpRequest();
    }
else
    {// code for IE6, IE5
       xmlCurr=new ActiveXObject("Microsoft.XMLHTTP");
    }
xmlCurr.open("GET",xmlURL,false);
xmlCurr.send();
xmlCurr.xml=xmlCurr.responseXML;
return xmlCurr;

但是没有用... 有人有什么想法吗？

更新：

我的代码似乎根本不运行 AJAX。

响应文本=“\r\n”
statusText =“确定”
我不知道如何确定 MIME 类型。但responseXML.xml =“”

更新：

感谢abieganski的建议 http://xkr .us/code/javascript/XHConn/ 我必须做一些调整，但它现在几乎可以工作了...

出于某种原因 - 我认为我的网站的设计方式 - 我必须将函数更改为同步，而不是使用回调函数异步

我不明白为什么，但我得到了responseText，但没有返回responseXML。因此 selectSingleNode 不起作用。因此我不得不写一段脏代码而不是 selectSingleNode

function selectSingleNode2(aXML,aNode) {
  aNode=aNode.substr(2,aNode.length-2);
  var b1=aXML.indexOf("<"+aNode+">")+aNode.length+2;
  var b2=aXML.indexOf("");
  var b3=aXML.substr(b1,b2-b1);
  返回b3； 
}

有什么想法为什么吗？谢谢你！

I have the following code:

var xmlCurr = new ActiveXObject("Microsoft.XMLDOM");
xmlCurr.async = false;
xmlCurr.load(xmlURL);
return xmlCurr;

From xmlCurr I need the following information

xmlCurr.xml
xmlCurr.documentElement
xmlCurr.selectSingleNode("result").text;

This code works well on IE6+, but does not work on Chrome or Firefox.

I have tried adapting code from
http://www.w3schools.com/Xml/xml_parser.asp

To get something like the following:

if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
     xmlCurr=new XMLHttpRequest();
    }
else
    {// code for IE6, IE5
       xmlCurr=new ActiveXObject("Microsoft.XMLHTTP");
    }
xmlCurr.open("GET",xmlURL,false);
xmlCurr.send();
xmlCurr.xml=xmlCurr.responseXML;
return xmlCurr;

But to no avail...
Does anyone have any ideas?

Update:

My code does not seem to run the AJAX at all.

The responseText = "\r\n"
The statusText="OK"
I do not know how to determine the MIME type. but the responseXML.xml=""

Update:

Thank you to abieganski for the suggestion from http://xkr.us/code/javascript/XHConn/
I had to do a little tweaking, but it is now almost working...

For some reason - I think the way my website is designed -I had to change the function to be synchronous as opposed to asynchronous with a callback function

I don't understand why but I got responseText back but not responseXML. Therefore selectSingleNode wouldn't work. Therefore I had to write a dirty piece of code instead of selectSingleNode

function selectSingleNode2(aXML,aNode) {
  aNode=aNode.substr(2,aNode.length-2);
  var b1=aXML.indexOf("<"+aNode+">")+aNode.length+2;
  var b2=aXML.indexOf("</"+aNode+">");
  var b3=aXML.substr(b1,b2-b1);
  return b3; 
}

Any ideas why?
Thank you!
