Element.removeAttribute()

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

属性名
DOMString指定要从元素中移除的属性的名称。如果指定的属性不存在,则removeAttribute()返回,但不会生成错误。

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。
