How to get the value of an input element in React
New Course Coming Soon:
Get Really Good at Git
Given a form, how do you get the value of one of the form fields?
A common scenario involves having a form, and you want to get the value of one of the form fields, for example when the user clicks a button.
How can you do so?
Using hooks, you can create a variable for each input field, and listening on the onChange
event you call the “set” function for that variable.
Here’s an example:
const [title, setTitle] = useState('')
And on the input field in JSX:
<input onChange={event => setTitle(event.target.value)} />
In this way, when you are in the event handler for the submit event of the form, or anywhere you want, you can get the value of the field from the title
value.
Are you intimidated by Git? Can’t figure out merge vs
rebase? Are you afraid of screwing up something any time
you have to do something in Git? Do you rely on ChatGPT
or random people’s answer on StackOverflow to fix your
problems? Your coworkers are tired of explaining Git to
you all the time? Git is something we all need to use,
but few of us really master it. I created this course to
improve your Git (and GitHub) knowledge at a radical
level. A course that helps you feel less frustrated with
Git. Launching Summer 2024. Join the waiting list!
