(windows).mouseleave(function() {

[Smorgen]

Hey,

I find this function highly annoying; (windows).mouseleave(function() {
How can we block this? What is does is pop up a window with register, subscribe to newsletter ect....
You can see it on http://www.geektime.com for example. Click on any article, then move your mouse to top of screen and it appears. It's very popular these days.

If you can't just disable JS on the site, create a surrogate script that blocks the mouseleave event from being sent.

Untested, but a starting point:

replacement:

Code: Select all

window.addEventListener("mouseleave", function(e){e.stopImmediatePropagation();}, false);

sources:

Code: Select all

@.geektime.com

[Smorgen]

It's not only that site, it's a lot of them. Can you do a *.com, *.net etc...?

[Smorgen]

I'm retarded when it comes to these kinds of things.....where do I add that?
Coding is like rocket science to me, it just doesn't compute....

[barbaz]

It's not only that site, it's a lot of them. Can you do a *.com, *.net etc...?

Sure.. here's a sources value for all .com & .net:

Code: Select all

@^https?://[^/:]+\.(?:com|net)[/:]

where do I add that?

go to about:config, right-click > new > string
name: noscript.surrogate.nomouseleave.replacement
value: replacement from above
right-click > new > string
name: noscript.surrogate.nomouseleave.sources
value: sources value from above

(you can change the "nomouseleave" to be anything you want as long as it's the same in the replacement & sources pref names)

You are a genius!!

Thanks for the positive feedback and glad it helped!

Code: Select all

@^https?://[^/:]+\.(?:com|net)[/:]

Why the (?: before the TLD?

Why the (?: before the TLD?

Habit of mine to use non-capturing parentheses when not needing to capture the contents.

Simpler approach is to use a URL Matcher:

Code: Select all

@.com .net

[barbaz]

Er, I kind of didn't know that was possible for TLDs
Thanks.

[Thrawn]

I believe URL matchers just do a text match, so they don't care whether it's a TLD.

[Smorgen]

Some sites still has the mouseleave. I checked and they are .com or .net. Strange....

[barbaz]

3 things I can think to try:
1) change the "false" to true
2) add also listener for "mouseout" event

Code: Select all

window.addEventListener("mouseleave", function(e){e.stopImmediatePropagation();}, false);window.addEventListener("mouseout", function(e){e.stopImmediatePropagation();}, false);

3) stopPropagation as well as stopImmediatePropagation (actually, I'm not sure if it's already fully covered by stopImmediatePropagation or not... but in case not...)

Code: Select all

window.addEventListener("mouseleave", function(e){e.stopImmediatePropagation();e.stopPropagation();}, false);

If none of those works, can you please provide a URL?

[Smorgen]

It works!
It was this site; http://www.supercompressor.com/ if you want to check it yourself.

Thanks a lot!
