How to use it:
Simply place the jquery.log.js bellow your jquery file. And call $.log(true) or $.log(false) whenever you want to activate/deactivate the logging system.
<script type="text/javascript" src="jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="jquery.log.js"></script>
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I'm trying to do a "smart" logging system. Meaning that I want this to simplfy my life when developing javascript with jQuery, not complicate it. So I've tried to keep it simple.
$.log(true); // starts the logging system
$("#foo").parents(".t1").next().prev().parent().find(".t2:last .t4:last").text("test");
$.log(false); // ends the logging system
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The results will be something like this: (the objects are clickable inside the console)
$('#foo'): [<div id="foo" class="t3"></div>]
parents('.t1'): [ <div class="t1">…</div> ]
next(undefined): [ <div class="t1">…</div> ]
prev(undefined): [ <div class="t1">…</div> ]
parent(undefined): [ <body>…</body> ]
find('.t2:last .t4:last'): [<div class="t4">teste</div>]
This has been tested against the official jQuery unit tests and it currently passes all except the "(6.3) core no conflict $" (which means if you use some other lib that overwrites $, it won't work with jquery log). I'll address this issue later, but most users shouldn't be affected by it.
I've had a discussion with Prinzhorn when I released the first version of this and meanwhile he made his own, which is also cool, you can find it at: https://github.com/Prinzhorn/jquery-inlog/
