The problem is that jQuery(“.date_picker_disabled”) finds elements with that class and binds to them. If elements don’t have the class at the time the binding is made, the events will not be handled. The on function allows you to get round this by handling them on another element when the event “bubbles up to” a … Read more
yes, you should use overloaded -= to unsubscribe an event. simply assigning a reference to null will not do that automatically. The object will still be listening to that event.
One can access the current event through window.event. Just using event is implicitly accessing window.event.
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
This is because the window is scrolling not the div. Try changing your element listener to the parent of the div (in this case the window) like this. window.addEventListener(“scroll”, function () { myFunc(); }, false);
Action<Object, EventArgs> a = (o, ea) => { }; EventHandler e = a.Invoke;
The unexpected behavior is due to the way in which Firefox and Chrome handle the closing of a Websocket. When the page is refreshed, both browsers close the connection, however, Firefox will execute your onclose code, while chrome closes the connection and skips straight to re-loading the new page. So yes, I confirm this strange … Read more
There actually is a good reason for requiring the second argument to derive from EventArgs if your fully-trusted code hosts third-party code as partially-trusted. Because the callback to the event handling delegate is done in the context of the raising code and not the third party code, it is possible for malicious third-party code to … Read more
Click is there for backwards compatibility, and is essentially the same as Tapped. 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
The following is what I see as benefits of using reactive event streams in a single-threaded synchronous application. 1. More declarative, less side-effects and less mutable state. Event streams are capable of encapsulating logic and state, potentially leaving your code without side-effects and mutable variables. Consider an application that counts button clicks and displays the … Read more
