Know when your elements and their children have transitionended.
npm install arrivalA little helper for knowing reliably when CSS transitions have finished.
With npm via browserify or your package manager of choice:
``
$ npm install arrival
With bower:
`
$ bower install icelab/arrival
Arrival will look at the passed element/s and traverse its children to find the element with the longest transition duration (determined by the sum of its transition-duration and transition-delay properties). Whenever that element finishes transitioning, the callback will fire.
`html`
Make slides go now
`js
var arrival = require('arrival');
var slides = document.querySelector('.slides');
var trigger = document.querySelector('.btn');
function callback() {
console.log('Like, totally all transitions were completed');
}
trigger.addEventListener('click', function(e){
arrival(slides, callback);
});
`
Arrival also takes a third argument, a selector that is used to match against all the passed elements and their children. This is useful in situations where you _know_ what elements are going to be the longest.
`js
var arrival = require('arrival');
...
trigger.addEventListener('click', function(e){
arrival(slides, callback, '.third');
});
`
There are a couple of build options run through browserify:
`
$ npm run build
$ npm run build-standalone
$ npm run build-standalone-min
npm run build-standalone generates the file used in the example ./test/index.html.
* Since there’s no transitionstart event, you’ll need to call arrival at the same time you trigger the transition.transition
* Arrival only looks at properties, not animation` properties for now.
* Arrival will blindly look at _all_ descendants of the passed elements (unless you tell it not to). If you have multi-stage transitions it may find the wrong element to bind to.
