Challenge: Build a Controlled Form Component
Task
In this challenge, you will create a Form component with two input fields: email and password. The goal is to use the useRef hook to reference the input elements and handle form submission logic.
Instructions
- Import the
useRefhook from thereactlibrary. - Inside the
Formcomponent, declare twouseRefvariables:emailRefandpasswordRef, initialized withnull. - Reset the input fields by setting their values to an empty string using the
useRefvariables.
- To import the necessary hook from the React library, include an
importstatement. - For this task, we will utilize the
useRefhook to store data without affecting the markup. - To determine the appropriate variable name for the ref, choose a word that is associated with the ref and add "Ref" at the end.
- To initialize the ref with
null, passnullas the initial value in the brackets of theuseRefhook (e.g.,useRef(null)). - To reset the form input, use the appropriate ref variable and assign its
.current.valueto an empty string ("").
