万恶的MS,IE11的selectNodes selectSingleNode

Question

js ie11

Answer 1

是支持的，
var xmlHelper = function ()
    {
        return {
            loadXmlFile: function (xmlFile)
            {
                /// <summary>加载XML文件,返回XmlDom对象</summary>
                /// <param name="xmlFile">加载的xml文件URI</param>                var xmlDoc;
                if (window.ActiveXObject!==undefined)
                {
                    xmlDoc = new ActiveXObject('Microsoft.XMLDOM');
                    xmlDoc.async = false;
                    xmlDoc.load(xmlFile);
                }
                else if (document.implementation && document.implementation.createDocument)
                {
                    try
                    {
                        xmlDoc = document.implementation.createDocument('', '', null);
                        xmlDoc.async = false;
                        xmlDoc.load(xmlFile);
                    }
                    catch (e)
                    {
                        var xmlhttp = new window.XMLHttpRequest();
                        xmlhttp.open("GET", xmlFile, false);
                        xmlhttp.send(null);
                        xmlDoc = xmlhttp.responseXML.documentElement;
                    }
                }
                else
                {
                    return null;
                }
                return xmlDoc;
            },
            loadXmlString: function (xmlString)
            {
                /// <summary>从xml格式字符串中加载XmlDom对象</summary>
                /// <param name="xmlString">XML格式字符串</param>
                var xmlDoc;
                if (window.ActiveXObject !== undefined)
                {
                    xmlDoc = new ActiveXObject('Microsoft.XMLDOM');
                    xmlDoc.async = false;
                    xmlDoc.loadXML(xmlString);
                }                 
                else if (document.implementation && document.implementation.createDocument)
                {
                    var oParser = new DOMParser();
                    var xmlDoc = oParser.parseFromString(xmlString, "text/xml");
                }
                else
                {
                    return null;
                }
                return xmlDoc;
            }
        }
    }();关键是这里面，以前普遍的判断是if (window.ActiveXObject)，但在IE11里，这个返回的是false，要用if (window.ActiveXObject!==undefined)

楼主，怎么解决的？-------------------document.implementation.hasFeatrue("xpath","2.0") 结果为false 。

Answer 3

selectNodes 方法改成 querySelectorAll 了
