jQuery-inlog (v 1.0.0)
See what your jQuery code does inside like a boss. jQuery-inlog is a passive plugin, which injects (js ftw!) console.log calls inside your jQuery core. It makes debugging of selectors and chains a breeze. No more alert($obj.length) and stuff...
I call it black-box magic. Or short: black magic. Or even shorter: js
The original idea was taken from https://github.com/fmsf/jQueryLog
Works in any Browser with a decent console (Opera for example doesn't know about "%o" format string). I personally think the output reads best on Firebug.
If you use jQuery-inlog I'd be very interested to hear from you! https://twitter.com/Prinzhorn
Example
Imagine the following markup
<body>
<div class="bar">
<div class="bar">
<div id="foo"></div>
</div>
</div>
<div id="bacon"></div>
</body>and the following jQuery calls
$l(true);
$("#foo").parents(".bar").next().prev().parent().fadeOut();
$l(false);will result in the following output with default settings
$("#foo") ↷ [div#foo]
parents(".bar") ↷ [div.bar, div.bar]
next() ↷ [div#bacon]
prev() ↷ [div.bar]
parent() ↷ [body]
fadeOut() ↷ [body]
or if you want to know what's really happening, set maxDepth: -1 (last branch expanded exemplarily)
+ $("#foo") ↷ [div#foo]
+ parents(".bar") ↷ [div.bar, div.bar]
+ next() ↷ [div#bacon]
+ prev() ↷ [div.bar]
+ parent() ↷ [body]
- fadeOut() ↷ [body]
- animate(Object { opacity="hide"}) ↷ [body]
- queue("fx", g()) ↷ [body]
- each(function()) ↷ [body]
- is(":hidden") ↷ false
- matchesSelector(<body style="opacity: 0.920047;">, ":hidden") ↷ false
isXML(<body style="opacity: 0.920047;">) ↷ false
isXML(Document index.html) ↷ false
- filter(":hidden", [body]) ↷ []
isXML(<body style="opacity: 0.920047;">) ↷ false
or even verbose with thisValue: true
+ (Window index.html).$("#foo") ↷ [div#foo]
+ ([div#foo]).parents(".bar") ↷ [div.bar, div.bar]
+ ([div.bar, div.bar]).next() ↷ [div#bacon]
+ ([div#bacon]).prev() ↷ [div.bar]
+ ([div.bar]).parent() ↷ [body]
- ([body]).fadeOut() ↷ [body]
- ([body]).animate(Object { opacity="hide"}) ↷ [body]
- ([body]).queue("fx", g()) ↷ [body]
- ([body]).each(function()) ↷ [body]
- ([body]).is(":hidden") ↷ false
- (function()).matchesSelector(<body style="opacity: 0.920047;">, ":hidden") ↷ false
(function()).isXML(<body style="opacity: 0.920047;">) ↷ false
(function()).isXML(Document index.html) ↷ false
- (function()).filter(":hidden", [body]) ↷ []
(function()).isXML(<body style="opacity: 0.920047;">) ↷ false
or if you're hardcore, you can set rawOutput: true to get the raw stackt race object created by the plugin
arguments
[".bar"]
function
"parents"
this
[div#foo]
sub
[Object { function="matches", arguments=[2], sub=[2], more...}, Object { function="pushStack", this=[1], arguments=[3], more...}]
return
[div.bar, div.bar]
Documentation / Reference
Include jquery.inlog.js after jQuery core and enable it by calling $l(true) or $l(options).
Note: $l is an alias for jQuery.inlog. If for any reason window.$l is already defined, it won't be overwritten.
Options:
var defaults = {
enabled: false,//Enable logging
thisValue: false,//Output this-value
returnValue: true,//Output return-value
indent: true,//Indent nested calls (makes sense for maxDepth !== 0)
maxDepth: 0,//Max depth of nested calls
rawOutput: false//If true, the raw stack trace objects will be printed (thisValue, returnValue and indent are all included for free)
};
