We change value of an element in DOM

  • DOM is a collection of node, and DOM node do not have a text value.

  • The text node is store the value in a child node.

  • Node text is the way to get the value of the child node.

  • The getElementsByTagName() method returns a node list.

  • Node list containing all elements in same order as they appear source documents.

We change the value in a text node

The nodeValue property is used to change the value of a text node.

Example

The following code changes the text node value:

<!DOCTYPE html>

<html>

<head>

<script type="text/javascript" src="loadxmldoc.html">

</script>

</head>

<body>

 

<script type="text/javascript">

    xmlDoc = loadXMLDoc("library.xml");

 

    a = xmlDoc.getElementsByTagName("title")[0].childNodes[0];

    a.nodeValue = "C# Language";

 

    document.write(a.nodeValue);

</script>

</body>

</html>

Define the code

  • First we create XML http object and open it.
  • XML http script send the request to the server.
  • "loadxmldoc.html" get the data.
  • Set the response as an XML DOM object.
  • Document. write is print the document
  • Change the node value of the text node to "C# language"
