beforeUpdate
Dispatched synchronously at the start of update(), before the new code is generated.
Syntax
- doodle.addEventListener('beforeUpdate', handler)
Fires for every update: manual, click:update and auto:update.
The seed of the outgoing render is still readable here.
Examples
const doodle = document.querySelector('css-doodle');
doodle.addEventListener('beforeUpdate', () => {
history.push(doodle.seed);
});
