React Textarea

This lesson is part of React · All levels

Summary

The textarea elements in React follow the same controlled component pattern, i.e. the attribute value is bound to the state and changed by onChange. Unlike HTML, the initial content of a textarea is written through value, not text between its tags. With this pattern, it's easy to validate and store.

Key points

Textarea uses value that refers to state
OnChange updates the state for each text change
Attributes rows set the initial high of the textarea
Do not put child text in the textarea tag when it is controlled
