Triggering a callback

​> ModalProp API​

You may often want to perform an action as soon as you open or close a modal. Up until now, you had to skillfully employ setTimeout() in order to trigger your function after the modal is done animated. With Modalfy v3, you no longer have to think about it thanks to the built-in support of callbacks.

1. When opening

The openModal() function now accepts a 3rd argument that designates your callback. Simply provide it and you should see it be invoked after the modal has been opened (this includes animation time as well).
TypeScript
openModal('ErrorModal', { titleColor: 'red' }, () => {
console.log(`βœ… Opened ErrorModal`)
})
As you can see, openModal()still expects themodalNameandparamsas the first two arguments, with the latter being optional.

2. When closing

As you'd expect, all the closing methods have also received a new argument that behaves in the same capacity:
TypeScript
closeModal(undefined, () => console.log('βœ… Closed latest opened modal'))
​
closeModals('ErrorModal', () => console.log('βœ… Closed all ErrorModal'))
​
closeAllModals(() => console.log('βœ… Closed all modals'))
You'll notice that closeModal() first argument is optional. That's you can either provide undefined (to close the latest opened modal) or specify a name to close another one.

Things to remember

If you're using animationIn/animationOut to drive the modal animations yourself, remember that you have to call the new callback argument there in order for your callbacks to be called. You can refer to the dedicated section in the Upgrading from v2.x guide to learn more about it.
