Description:
Welcome to this video from tutorialsinhand.com. In this video we are going to discuss on refs in react.
Refs in React
Refs is an abbreviation for references in React. Like keys, refs are also attributes which helps to store a reference to any particular DOM node within our JSX element. It provides a way to access DOM nodes or elements and how we developers write code to interact with it or change value of the child component without accessing props and all.
In the below given situations we can use refs which can be beneficial.
When we need to interact with the Browser DOM and update it based on certain situations.
Great to use with animations.
Can be used with third party libraries, downloaded from “npm”.
Can be used as in callbacks.
In react, when we use refs with an element, we can access the reference to the DOM node using the “current” property. Now what will be stored in the “current” property depends on where “ref” have been used.
When we use ref attribute with HTML element, we can access its underlying DOM element with “current” property.
When used on class component, we can access the mounted instance.
