With the 2nd solution, you have to manually call the previous functions, making it hard to remove specific listeners (which, to me, sounds like something you’d rather want than clearing all listeners), while on the first solution, you can only clear them all at the same time, unless you want to emulate the first functionality. … Read more

There’s no “stop” event here really – you get an event when you do scroll, so every time a mousewheel event happens the event is triggered…when there’s nothing you’ll get no events and your handler won’t be firing. You ca however detect when the user hasn’t used it in say 250ms, like this: $(“#myElem”).mousewheel(function() { … Read more
Often, event queues are implemented as command design pattern: In object-oriented programming, the command pattern is a design pattern in which an object is used to represent and encapsulate all the information needed to call a method at a later time. This information includes the method name, the object that owns the method and values … Read more
Here’s a simple example: function live(eventType, elementId, cb) { document.addEventListener(eventType, function (event) { if (event.target.id === elementId) { cb.call(event.target, event); } }); } live(“click”, “test”, function (event) { alert(this.id); }); The basic idea is that you want to attach an event handler to the document and let the event bubble up the DOM. Then, check … Read more

Tapped is a “high level gesture” that will translate automatically to a click, tap, pen press, etc. and is what I would recommend to use. PointerPressed is not what you want. Here’s why: if I press and hold, the PointerPressed event will … Read more
$event is the event itself. The event binding (someevent) allows to bind to DOM events and to EventEmitter events. The syntax is exactly the same. For DOM events $event is the MouseEvent, KeyboardEvent, or the event value of the type of whatever event you listen to. For EventEmitter events the emitted value is available as … Read more
In IE, the event object was a global object, (which is not passed to the handler function) but accessed as a global object. You can also access it as a property of the window object like window.event In in FF and other browsers the event object was passed as an argument, since in FF there … Read more
Use the data function as is done by jQuery internally. On previous versions, you could call it like for other data : obj.data(‘events’); In jQuery 1.8, this direct access was removed, so in recent versions you must call it like this : $._data(obj[0], “events”) You can see it in action by opening the console in … Read more

It will not work on Windows Forms or any other UI framework. The below is a helpful utility method for removing … Read more
