Mithril.js: Debounce events
Disable auto-redraw with e.redraw = false
and use a timeout.
Example using the oninput event:
let timeout
let value = '25'
function oninput(e) {
e.redraw = false
// Update state because we are using a controlled component
value = e.currentTarget.value
clearTimeout(timeout)
timeout = setTimeout(() => {
// Do something more here if needed
// Plus probably redraw manually
m.redraw()
}, 1000)
}
const App = {
view: () => [
m('input[type=text]', { oninput, value }),
// Updating of this value is debounced
m('p', Math.sqrt(value)),
],
}
