Getting the last child node
If your code needs to work with the last child node, use the lastChild property of the parent element:
parent.lastChild
Note:parent is the parent element.
For example, suppose you want to work with the last child node of the p element from the HTML example at the beginning of this section. Hereâs some code thatâll do the job:
const para = document.querySelector("main > p");
const lastParaChildNode = para.lastChild;
In this example, the resulting node is a text node representing the question mark (?) and the white space to the </p> tag. If you want the last child element node, use the lastElementChild property, instead:
parent.lastElementChild
Note:parent is the parent element.
To get the last child element node of the p element from the code at the beginning of this section, you could do this:
const para = document.querySelector("main > p");
const lastParaChildElement = para.lastElementChild;
In the example, this code returns the a element.
