¿Cómo se utiliza la propiedad valor de nodo en Dom?

How is the nodevalue property used in the Dom?

The nodeValue property is used to get the text value of a node. The getAttribute () method returns the value of an attribute. In the DOM, everything is a node. Element nodes do not have a text value. The text value of an element node is stored in a child node. This node is called a text node.

Get the Value of an Element. In the DOM, everything is a node. Element nodes do not have a text value. The text value of an element node is stored in a child node. This node is called a text node. To retrieve the text value of an element, you must retrieve the value of the elements’ text node.

In the console of nodes.html, click on the first element in the body, which is an h1 element. In the console, get the node type of the currently selected node with the nodeType property. With the h1 element selected, you would see 1 as the output, which we can see correlates to ELEMENT_NODE.

The DOM Tree and Nodes. In addition to these three node types, the document itself is a document node, which is the root of all other nodes. The DOM consists of a tree structure of nested nodes, which is often referred to as the DOM tree. You may be familiar with an ancestral family tree, which consists of parents, children, and siblings.

The nodeName property returns the name of the specified node. If the node is an element node, the nodeName property will return the tag name.

It returns different values for different nodes such as if the node attributes, then the returned string is the attribute name or if the node is an element, then the returned string is the tag name. It is a read-only property. Return values: This property returns the name of current node.

This example uses the nodeName and nodeType property to get node name and type of the root element in “books.xml”. In the XML DOM, each node is an object. Objects have methods and properties, that can be accessed and manipulated by JavaScript. The nodeName property specifies the name of a node. Try it Yourself.
