Element.removeAttributeNode() - Web APIs 编辑

The removeAttributeNode() method of the Element object removes the specified attribute from the current element.

Syntax

removedAttr = element.removeAttributeNode(attributeNode)

attributeNode is the Attr node that needs to be removed.
removedAttr is the removed Attr node.

Example

// Given: <div id="top" align="center" />
var d = document.getElementById("top");
var d_align = d.getAttributeNode("align");
d.removeAttributeNode(d_align);
// align is now removed: <div id="top" />

Notes

If the removed attribute has a default value, it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix, when applicable.

There is no removeAttributeNodeNS method; the removeAttributeNode method can remove both namespaced attributes and non-namespaced attributes.
