DOM Node isSameNode() Method
Example
Check if two nodes are, in fact, the same node:
var item1=document.getElementById("myList1");
var item2=document.getElementsByTagName("UL")[0];
item1.isSameNode(item2);
var item2=document.getElementsByTagName("UL")[0];
item1.isSameNode(item2);
The result will be:
true

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
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.
