HTML | DOM importNode() Method
  • Last Updated : 26 Nov, 2019

The HTML | DOM importNode() Method creates a copy of a node from another document and imports it to the current document.

Syntax:

document.importNode(externalNode, [deep])

Parameters:

  • externalNode: Node which we need to import from another document, it can be of any type.
  • [deep]: We can set its value to “true” if we want to copy the node along with its attributes and child nodes and “false” if we want to copy the node and its attributes only. If we do not specify any argument, then the value of deep is taken as “true” by default.

Example-1:




<!DOCTYPE html>
<html>
  
<body>
  
    <!-- iframe is used to create a new frame inside
     our current document and merge another document into it-->
    <!-- you can put your own source in iframe src -->
    <iframe src="D:\Normalize() Method\Normalize.html" 
            style="height:380px;width:520px;"></iframe>
    
    <button onclick="myNode()">Try it</button>
  
    <script>
        function myNode() {
  
            // accessing the iframe using frame variable
            var frame = document.getElementsByTagName("IFRAME")[0]
  
            // here we are accessing the <h1> element from 
            // the document contained inside the iframe.
            var geek = 
                frame.contentWindow.document.getElementsByTagName("H1")[0];
              
            // applying importNode() method adding 
            //imported node to our original document.
            var gfg = document.importNode(geek, true);
            document.body.appendChild(gfg);
        }
    </script>
  
</body>
