There are way too many ways to stub functions or methods, but at the end of the day all we want to know is always the same: has that function been invoked ? has that function received the expected context ? which argument has been passed to that function ? what was the output of the function ? Update thanks to @bga_ hint about the output property in after notification, it made perfect sense The Concept For fun and no profit I have created a prototype which aim is to bring a DOM like interface to any sort of function or method in order to monitor its lifecycle: the "before" event, able to preventDefault() and avoid the original function call at all the "after" event, in order to understand if the function did those expected changes to the environment or to a generic input object, or simply to analyze the output of the previous call the "error" event, in case we want to be notified if something went wrong during function execution the "handlerer...

Update I have discussed this object a part and I agree that the url could be used as unique id as well. In this case the server should use the static url as unique id: StaticJSONP.notify("http://cdn.com/static/article/id.js",{..data..}); So that on client side we can use the simplified signature: StaticJSONP.request( "http://cdn.com/static/article/id.js", function (uid, data) { } ); The callback will receive the uid in any case so that we can create a single callback and handle behaviors accordingly. The script has been updated in order to accept 2 arguments but, if necessary, the explicit unique id is still supported. Under the list of " incomplete and never posted stuff " I found this article which has been eventually reviewed. I know it's " not that compact " but I really would like you to follow the reason I thought about a solution to a not so common, but quite nasty, problem. Back in 2001, my early attempts to include cal...

Today I would like to introduce you a quite uncommon JavaScript trick , a trapped Live Object or, generally speaking, a lightweight monitor able to understand when a generic property has been changed. About Live Objects A live object could be described as a particular object able to change without our interaction. The most common live object example is this: // this is the most common live object // the HTMLCollection var divs = document.getElementsByTagName("div"); divs.length; // let's say 4 // let's add another div inside a generic node document.body.appendChild( document.createElement("div") ); divs.length; // 5! In few words DOM searches are dynamic, which is the reason almost every selector library needs to transform the current result into a static Array . About LiveMonitor Specially suited for live objects, LiveMonitor is a function which aim is to notify us when the specified property change: // LiveMonitor example var lm = new LiveMonitor( ...
