 ### Events
 
-Mithril supports event handler binding for all DOM events, using `addEventListener` under the hood to add events in case they don't have a corresponding `on${event}` property, such as the native `touchstart` or third-party events like Bootstrap's `show.bs.modal`.

-You may access the element itself through `this` like so, which is useful for things like form validation:
-
-```javascript
-function submit(e) {
-	this.validate()
-	m.request("api/form-endpoint", {
-		method: "POST",
-		data: new FormData(this),
-		background: true
-	})
-	.then(function () {
-		m.route.set("/form-submit")
-	})
-}

-m("form", {onsubmit: submit}, [

-It also provides access to the event's own literal vnode via `vnode`, so you may easily access its `attrs` and `children` through it, from an external function.

-function handleClick(e, vnode) {
