IE9和IE10下有效，不过最好还是用IE10的兼容模式，否则别的一些js方法也变了
在ext-all.js下找这个getAttributeNS 方法修改成以下代码
getAttributeNS : (Ext.isIE && !(/msie 9/.test(navigator.userAgent.toLowerCase()) && document.documentMode === 9) && !(/msie 10/.test(navigator.userAgent.toLowerCase()) && document.documentMode === 10)) ? function(ns, name){
var d = this.dom;
var type = typeof d[ns+":"+name];
if(type != 'undefined' && type != 'unknown'){
return d[ns+":"+name];
}
return d[name];
} : function(ns, name){
var d = this.dom;
return d.getAttributeNS(ns, name) || d.getAttribute(ns+":"+name) || d.getAttribute(name) || d[name];
}
