There are three different phases during lifecycle of an JavaScript event. Capturing Phase. Target Phase. Bubbling Phase.
When an ASP.NET page runs, the page goes through a life cycle in which it performs a series of processing steps. These include initialization, instantiating controls, restoring and maintaining state, running event handler code, and rendering.
The lifecycle of an HTML page has three important events: DOMContentLoaded – the browser fully loaded HTML, and the DOM tree is built, but external resources like pictures <img> and stylesheets may not yet have loaded. load – not only HTML is loaded, but also all the external resources: images, styles etc.
When an event is fired on an element that has parent elements (in this case, the <video> has the <div> as a parent), modern browsers run three different phases — the capturing phase, the target phase, and the bubbling phase.
There is bunch of information out here:
