Given an HTML document and the task is to select a particular element and get all the child elements of the parent element with the help of JavaScript. For this, there are 2 ways to get the child element:
We will discuss both approaches & understand their implementation through the examples. The DOM children property is used to return HTMLcollection of all the child elements of the specified element. Approach 1:
Example 1: This example implements the .children property to get the HTMLcollection of all the child elements of the specified element. HTML
Output: class Property The querySelector() method in HTML is used to return the first element that matches a specified CSS selector(s) in the document. Approach 2:
Example 1: This example implements the .querySelector() method to get the first element to match for the specified CSS selector(s) in the document. HTML
Output: .querySelector() Method How do I get parent node?To get the parent node of an HTML element, you can use the parentNode property. This property returns the parent node of the specified element as a Node object. The parentNode property is read-only, which means you can not modify it. In HTML, the document is itself the parent node of html element.
How do you find the parent element of a class?Use the closest() method to get the closest parent element by class, e.g. child. closest('. parent') . The closest() method traverses the Element and its parents until it finds a node that matches the provided selector.
What is parentNode in JavaScript?The read-only parentNode property of the Node interface returns the parent of the specified node in the DOM tree. Document and DocumentFragment nodes can never have a parent, so parentNode will always return null . It also returns null if the node has just been created and is not yet attached to the tree.
What is the difference between parentNode and parentElement?Parent Element returns null if the parent is not an element node, that is the main difference between parentElement and parentNode. In many cases one can use anyone of them, in most cases, they are the same.
