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
//删除之前 <div id="div1" align="left" width="200px">
let div = document.getElementById("div1")
div.removeAttribute("align");
//删除之后 <div id="div1" width="200px">
注释
你应该使用 removeAttribute 而不是使用setAttribute将属性值设置为null。
尝试删除不在元素上的属性不会引发异常。
