FW: [Greasemonkey] Including other JS files and using "class" and custom styles

[Philip Friedman - Auto Europe]

Stefano,

The regexp in the xmlhttprequest is only to make the example work regardless
of it's URL. Notice the libraryTest.user.js Greasemonkey @include directive
(as in executes based on the URL of) references itself, so in the contrived
example document.location.href contains the path of the library.js file URL.


In the real world, you will want to replace everything after "url:" with the
URL to YOUR library.js file. It may be a literal. It may be anywhere
xmlhttpRequest can find it. 

I append the URL with +'?'+Math.random() to force the latest version while I
am modifying the library. There are performance issues to consider when
requesting large files from remote servers.

|I am not sure I fully understand this, Philip.
|
|   1. what's the meaning of the regexp in the xmlhttprequest call?
|   2. can I include from a "different site"? I mean, my GM script is
|      stored someowhere on the client's PC and I want it to access a
|      Javascript file that is on my web server...
|   3. not sure I understand what you mean by "@includes 
|itself" and what
|      does not make sense in the real world.
|
|Thanks for your patience
|regards
|/Stefano
