Dom what is a text node

Post Content. All rights reserved. Sets or returns the text content of a CommentNode , TextNode or comment element. Returns a Boolean value that indicates whether the current TextNode only contains whitespaces.

Returns the number of characters within a TextNode , CommentNode or comment object. Returns a reference to the next child of the current element's parent. Returns the document object that contains the current node. Returns the parent element of the object in the DOM hierarchy. Returns the parent element of the current node in the DOM hierarchy. Returns a reference to the previous node of the current element's parent. Sets or returns the text content of an element including the text content of its descendants.

Registers an event handler function event listener for the specified event on the current object. Appends the specified text content to the end of the current TextNode , CommentNode or comment element. Compares the placement of the specified node with the current node in the DOM hierarchy. However, if a next node has an element node, then it may have a sibling.

To get a sibling, we can use the nextSibling property. For instance, if we have:. Then if we write:. The textContent property can be used to get all child text nodes and set the content for a specific text node.

If we use it as a getter, then it returns all the textual content of a node as a concatenated string. Then we get the content of those elements with some whitespace.

We can use it to remove all child nods and replace them with a single text node. For example, we can write:.

It also returns the contents of script and style elements. Most browsers except Firefox support a similar property to textContent called innerText. So we have hidden text, innerText will ignore it.
