Definition and Usage

The isSameNode() method checks if two nodes are the same node.

The isSameNode() method returns true if the two nodes are the same node, otherwise false.

Tip: Use the isEqualNode() method to check if two nodes are equal, but not necessarily the same node.


Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The isSameNode() method is supported in all major browsers, except Firefox.

Note: Firefox stopped supported this method as of version 10, because the method has been deprecated in the DOM version 4. Instead, you should use === to compare if two nodes are the same.

Note: Internet Explorer 8 and earlier does not support this method.
