元素 方法 removeAttribute() removes the attribute with the specified name from the element.

句法

element.removeAttribute(attrName);
					

参数

attrName

DOMString specifying 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

undefined .

用法注意事项

应使用 removeAttribute() instead of setting the attribute value to null either directly or using setAttribute() . Many attributes will not behave as expected if you set them to null .

DOM methods dealing with element's attributes:

Not namespace-aware, most commonly used methods	Namespace-aware variants (DOM Level 2)	DOM Level 1 methods for dealing with Attr nodes directly (seldom used)	DOM Level 2 namespace-aware methods for dealing with Attr nodes directly (seldom used)
setAttribute (DOM 1)	setAttributeNS	setAttributeNode	setAttributeNodeNS
getAttribute (DOM 1)	getAttributeNS	getAttributeNode	getAttributeNodeNS
hasAttribute (DOM 2)	hasAttributeNS	-	-
removeAttribute (DOM 1)	removeAttributeNS	removeAttributeNode	-

范例

// Given: <div id="div1" align="left" width="200px">
document.getElementById("div1").removeAttribute("align");
// Now: <div id="div1" width="200px">
