对象没有't支持属性或方法'transformNode'在Internet Explorer 1

Object doesn't support property or method 'transformNode' in Internet Explorer 10 (Windows 8)

本文关键字：transformNode Internet 方法 Explorer 支持 对象 属性      更新时间：2023-09-26

我遇到了一些JavaScript问题，这些问题似乎只出现在Windows 8上的Internet Explorer 10中（IE 7、8和9都可以正常工作）。我所做的基本工作是从web服务中获取XML和XSL，然后用JavaScript将它们转换为使用Sys.Net.XMLDOM对象在页面上呈现。

XMLDOM = Sys.Net.XMLDOM;
var xsl = // XSL gotten from somewhere else 
var xmlString = // XML gotten from somewhere else as a string...
var xml = new XMLDOM(xmlString);
var content = xml.transformNode(xsl);

当我在IE 10中使用上述代码时，我得到：

对象不支持属性或方法"transformNode"

关于InternetExplorer10为什么这么做，有什么想法吗？

编辑

我也试过这个：

xmldoc = new ActiveXObject("Msxml2.DOMDocument"); 
xmldoc.async = false; 
xmldoc.load(xml); 
xsldoc = new ActiveXObject("Msxml2.DOMDocument"); 
xsldoc.async = false; 
xsldoc.load(xsl); 
var content = xmldoc.transformNode(xsldoc);

它适用于所有以前版本的IE，但在IE 10中我得到：

对未声明的命名空间前缀的引用："atom"。

IE 9和grater不支持它，请尝试此功能（在线找到）

function TransformToHtmlText(xmlDoc, xsltDoc) {
    if (typeof (XSLTProcessor) != "undefined") { // FF, Safari, Chrome etc
        var xsltProcessor = new XSLTProcessor();
        xsltProcessor.importStylesheet(xsltDoc);
        var xmlFragment = xsltProcessor.transformToFragment(xmlDoc, document);
        return GetXmlStringFromXmlDoc(xmlFragment);
    }
    if (typeof (xmlDoc.transformNode) != "undefined") { // IE6, IE7, IE8
        return xmlDoc.transformNode(xsltDoc);
    }
    else {
        try { // IE9 and grater
            if (window.ActiveXObject) {
                var xslt = new ActiveXObject("Msxml2.XSLTemplate");
                var xslDoc = new ActiveXObject("Msxml2.FreeThreadedDOMDocument");
                xslDoc.loadXML(xsltDoc.xml);
                xslt.stylesheet = xslDoc;
                var xslProc = xslt.createProcessor();
                xslProc.input = xmlDoc;
                xslProc.transform();
                return xslProc.output;
            }
        }
        catch (e) {
            alert("The type [XSLTProcessor] and the function [XmlDocument.transformNode] are not supported by this browser, can't transform XML document to HTML string!");
            return null;
        }
    }
}
var content = TransformToHtmlText(xml, xsl);

找到了答案：http://blogs.msdn.com/b/ie/archive/2012/07/19/xmlhttprequest-responsexml-in-ie10-release-preview.aspx

IE 10要求使用responseType设置为"msxml文档"的XMLHttpRequest。一旦我把代码切换到这个位置，所有浏览器都能完美工作：

if (window.XMLHttpRequest) {
    xhr = new XMLHttpRequest();
} else {
    xhr = new ActiveXObject("Microsoft.XMLHTTP"); // For IE 6
}
xhr.open("GET", url, false);
try { xhr.responseType = "msxml-document"; } catch (e) { };
xhr.send();

首先归功于Roel van Lisdonk，他发布了Sheik Heera共享的函数。

我发现这个函数在Chrome中不起作用，因为GetXmlStringFromXmlDoc（），所以我使用了XMLSerializer:

例如：

if (typeof(GetXmlStringFromXmlDoc)!= "undefined")
{       
    return GetXmlStringFromXmlDoc(xmlFragment);
}
else
{
    // chrome friendly
    // get a xml serializer object
    var xmls = new XMLSerializer();
    // convert dom into string
    var sResult = xmls.serializeToString(xmlFragment);
    //extract contents of transform iix node if it is present
    if (sResult.indexOf("<transformiix:result") > -1)
    {
        sResult = sResult.substring(sResult.indexOf(">") + 1, sResult.lastIndexOf("<"));
    }       
    return sResult;
}

修改后的功能现在是：

function TransformToHtmlText(xmlDoc, xsltDoc) 
{
    // 1.
    if (typeof (XSLTProcessor) != "undefined") 
    {
        var xsltProcessor = new XSLTProcessor();
        xsltProcessor.importStylesheet(xsltDoc);
        var xmlFragment = xsltProcessor.transformToFragment(xmlDoc, document);
        if (typeof(GetXmlStringFromXmlDoc)!= "undefined")
        {       
            return GetXmlStringFromXmlDoc(xmlFragment);
        }
        else
        {
            // chrome friendly
            // get a xml serializer object
            var xmls = new XMLSerializer();
            // convert dom into string
            var sResult = xmls.serializeToString(xmlFragment);
            //extract contents of transform iix node if it is present
            if (sResult.indexOf("<transformiix:result") > -1)
            {
                sResult = sResult.substring(sResult.indexOf(">") + 1, sResult.lastIndexOf("<"));
            }       
            return sResult;
        }
    }
    // 2.
    if (typeof (xmlDoc.transformNode) != "undefined") 
    {
        return xmlDoc.transformNode(xsltDoc);
    }
    else {
            var activeXOb = null;
            try { activeXOb = new ActiveXObject("Msxml2.XSLTemplate"); } catch (ex) {}
        try {
            // 3
            if (activeXOb) 
            {
                var xslt = activeXOb;
                var xslDoc = new ActiveXObject("Msxml2.FreeThreadedDOMDocument");
                xslDoc.loadXML(xsltDoc.xml);
                xslt.stylesheet = xslDoc;
                var xslProc = xslt.createProcessor();
                xslProc.input = xmlDoc;
                xslProc.transform();
                return xslProc.output;
            }
        }
        catch (e) 
        {
            // 4
            alert("The type [XSLTProcessor] and the function [XmlDocument.transformNode] are not supported by this browser, can't transform XML document to HTML string!");
            return null;
        }
    }
}

我在IE 9中遇到了同样的问题，直到我停止尝试使用jQuery加载xslt文件，所有答案都没有帮助。我加载了一个脚本文件，如中所述：https://msdn.microsoft.com/en-us/library/ms762796%28v=vs.85%29.aspx.

然后我就可以使用transformNode()函数了。这是他们给出的脚本：

<HTML>
<HEAD>
  <TITLE>sample</TITLE>
  <SCRIPT language = "javascript">
     function init()
     {
        var srcTree =
           new ActiveXObject("Msxml2.DOMDocument.6.0");
        srcTree.async=false;
        // You can substitute other XML file names here.
        srcTree.load("hello.xml"); 
        var xsltTree =
           new ActiveXObject("Msxml2.DOMDocument.6.0");
        xsltTree.async = false;
        // You can substitute other XSLT file names here.
        xsltTree.load("hello.xsl");
        resTree.innerHTML = srcTree.transformNode(xsltTree);
     }
  </SCRIPT>
</HEAD>
<BODY onload = "init()" >
   <div id="resTree"></div>
</BODY>
</HTML>
