元素方法 removeAttribute() 从指定的元素中删除一个属性。
语法
element.removeAttribute(attrName);
参数
attrName- A
DOMStringspecifying the name of the attribute to remove from the element. If the specified attribute does not exist,removeAttribute()returns without generating an error.
返回值
IE 返回boolean类型值，其他返回undefined
注意：因为 removeAttribute() 不会返回任何有效值，你不能使用链式方法（连续使用方法，例如 document.body.removeAttribute("first").removeAttribute("second")…）连续移除多个属性。
使用说明
若要彻底移除一个属性的效果，应当使用 removeAttribute()，而不是使用 setAttribute() 将属性值设置为 null。对于许多属性，如果仅将其值设为 null，这不会造达成和预期一样的效果。
