jQuery-inlog allows you to easily debug your jQuery code. See exactly what you pass to functions, what they return and in which context (this-value) they were executed. No more alert($obj.length) to see if your selector worked. No more pain when chaining many calls and figuring out which one fails Include jquery.inlog.js after jQuery core and enable it by calling $l(true) or $l(options).
