removeAttribute() 从指定的元素中删除一个属性。
句法
element.removeAttribute(attrName)
attrName是一个字符串，将要从元素中删除的属性名。
例子
// <div id="div1" align="left" width="200px">
let div = document.getElementById("div1")
div.removeAttribute("align");
// now: <div id="div1" width="200px">
注释
You should use removeAttribute instead of setting the attribute value to null using setAttribute.
Attempting to remove an attribute that is not on the element doesn't raise an exception.
