document.implementation.createDocument("","",null);2、處理空白和換行的方式 Firefox，以及其他一些瀏覽器，會把空的空白或換行作為文本節點來處理，而 Internet Explorer 不會這樣。 思考: 那么怎么解決這種差異呢，下面是一種方法： for(var i=0;i<provinces.length;i++){ //在輸出所有的子節點的時候 if(provinces[i].nodeType==1){//在這里判斷該節點是否是元素節點 } } 要注意的是: xmlDoc.async = false; 寫成這樣 IE ， fireFox 都可以 xmlDoc.async = "false"; IE 可以 fireFox 會報錯 --></p></div>
