调试报错 ActiveXObject is not defined

[translace]

游戏是cocos 2.3.2引擎，打包后rpk调试报错ActiveXObject is not defined，该错误由cocos2d-runtime.js引起，但该套源码转到oppo和小米均能正常运行。

ActiveXObject在cocos2d-runtime.js内的定义：

v.getXMLHttpRequest = function () {
        return window.XMLHttpRequest ? new window.XMLHttpRequest : new ActiveXObject("MSXML2.XMLHTTP")
    }
...
...
cc.SAXParser.prototype = {
    constructor: cc.SAXParser,
    parse: function (t) {
        return this._parseXML(t)
    },
     _parseXML: function (t) {
        var e;
        return this._isSupportDOMParser ? e = this._parser.parseFromString(t, "text/xml") : ((e = new ActiveXObject("Microsoft.XMLDOM")).async = "false", e.loadXML(t)), e
    }
}
