charliepark / textareaAutogrow.js
Last active Nov 25, 2019
Fairly low-effort JS to set a textarea to grow in height to accomodate the text within.
View textareaAutogrow.js
// This is seven lines of vanilla JS that does most of what larger packages (like do.
// Might not work for your purposes, but it did for mine, and I figured I'd share.
const autogrow = (event) => {
const { target: textarea } = event;
const { textLength, style: { lineHeight, paddingTop, paddingBottom } } = textarea;
const widthInCharacters = parseInt(, 10);
const adjustmentFactor = 0.8; // tune this up or down if the height is too aggressive (or not aggressive enough)
const lines = Math.floor(textLength * adjustmentFactor / widthInCharacters) + 1;
const height = `calc(${lines * lineHeight}em + ${paddingTop} + ${paddingBottom})`;
