a mouseover event will be in most browsers triggered automatically, and in

other browsers it will be triggered when the user moves his mouse by 1px.
|

Here are the behavior I noticed, all on Windows:
|

- Safari 5.1: auto-triggers after 0 ms
|

- IE 11: auto-triggers after 30-80 ms (looks like it depends on page's size)
|
||||
- Firefox: auto-triggers after 10 ms
|
||||
- Opera 18: auto-triggers after 10 ms
|
||||
|
||||
- Chrome: triggers when cursor moved
|
||||
- Opera 12.16: triggers when cursor moved
|
||||
|
||||
To remedy to this, we do not start preloading if last display occurred less than
|
||||
100 ms ago. If they happen to click on the link, they will be redirected.

/* If the page isn't preloaded, it likely means
|

the user has focused on a link (with his Tab
|
||||
key) and then pressed Return, which triggered a click.
|
||||
Because very few people do this, it isn't worth handling this
|
||||
case and preloading on focus (also, focusing on a link
|
||||
doesn't mean it's likely that you'll "click" on it), so we just
|
||||
redirect them when they "click".
|
||||
It could also mean the user hovered over a link less than 100 ms
|
||||
after a page display, thus we didn't start the preload (see
|
||||
comments in `preload()` for the rationale behind this.)
|
||||
|
||||
If the page is waiting for completion, the user clicked twice
|
||||
while the page was preloading.
|
||||
Two possibilities:
|
||||
1) He clicks on the same link again, either because it's slow
|
||||
to load (there's no browser loading indicator with
|
||||
InstantClick, so he might think his click hasn't registered
|
||||
if the page isn't loading fast enough) or because he has
|
||||
a habit of double clicking on the web;
|
||||
2) He clicks on another link.
|
||||
|
||||
In the first case, we redirect him (send him to the page the old
|
||||
way) so that he can have the browser's loading indicator back.
|
||||
In the second case, we redirect him because we haven't preloaded
|
||||
that link, since we were already preloading the last one.
|
||||
|
||||
Determining if it's a double click might be overkill as there is
|
||||
(hopefully) not that many people that double click on the web.
|
||||
Fighting against the perception that the page is stuck is
|
||||
interesting though, a seemingly good way to do that would be to
|
||||
later incorporate a progress bar.
