element.removeAttribute

The Element method removeAttribute() removes the attribute with the specified name from the element.

Syntax

element.removeAttribute(attrName);

Parameters

attrName: A 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.

Return value

undefined.

Note: Since removeAttribute() doesn't return a value, you can't chain multiple calls together to remove multiple attributes at once.

Usage notes

You should use 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.

`getAttribute` (DOM 1)	`getAttributeNS`	`getAttributeNode`	`getAttributeNodeNS`
`hasAttribute` (DOM 2)	`hasAttributeNS`	-	-
