Element.removeAttributeNS() - Web API 接口参考编辑

removeAttributeNS 移除元素的指定属性

在Firefox 3及更高版本中，此方法会将DOM值重置为其默认值。

用法

element.removeAttributeNS(namespace,attrName);

namespace 包含当前属性的namespace字符串
attrName 当前移除的属性名字符串

例子

// <div id="div1" xmlns:special="http://www.mozilla.org/ns/specialspace"
//      special:specialAlign="utterleft" width="200px" />
d = document.getElementById("div1");
d.removeAttributeNS("http://www.mozilla.org/ns/specialspace", "specialAlign");
// now: <div id="div1" width="200px" />
