setAttributeNode() method adds a new Attr node to the specified element.

句法

var replacedAttr = element.setAttributeNode(attribute);

属性 是 Attr node to set on the element.
replacedAttr is the replaced attribute node, if any, returned by this function.

范例

This example copies the align attribute from one element to another.

HTML

<div id="one" align="left">one</div>
<div id="two">two</div>

JavaScript

let d1 = document.getElementById('one');
let d2 = document.getElementById('two');
let a = d1.getAttributeNode('align');
d2.setAttributeNode(a.cloneNode(true));
// Returns: 'left'
alert(d2.attributes[1].value);

注意事项

If the attribute named already exists on the element, that attribute is replaced with the new one and the replaced one is returned.

This method is seldom used, with Element.setAttribute() usually being used to change element's attributes.
