new WatchPage( spaInstance )

Description

Class for monitoring and logging mutations to a page.

This is intended to explore new and modified pages.

As elements are loaded, they are modified with a data-counter property to indicate the order they were loaded. This can be used to find page useful values for PageDetails's readySelector.

This class logs a lot and modifies every element encountered, slowing down pages. It is unlikely it should always be enabled.

After registering this class, in the console, do a query for the largest data-counter value to see what the last thing loaded was. Having timestamps turned on in the console helps identify when initial loading has completed.

Parameters
Name Type Description
spaInstance NexusHoratio.spa.SPA

SPA instance that manages this Page.
Examples
$$('[data-counter]:not(svg,img,figure)')
			  .map(x => [x.dataset.counter, x])
			  .sort((a,b) => (b[0] - a[0]))
