It is incorrect to say that unregistering the handlers from the Session events will somehow allow a Session object to be collected by the GC. Here is a diagram that illustrates the reference chain of events. ————– ———— —————- | | | | | | |Event Source| ==> | Delegate | ==> | Event Target … Read more
You need to stop the event from propagating up the DOM tree: $(‘.closeBtn’).click(function (evt) { evt.stopPropagation(); // Your code here });
What works is, if you set scope.text = $attrs.text; inside the linking and the controller functions. This will only work initially, as there is no 2way- databinding. You can use $attrs.observe though. See fiddle: http://jsfiddle.net/JohannesJo/nm3FL/2/
Button controls have a PerformClick() method that you can call. button1.PerformClick();
public void keyPressed(KeyEvent e) { int keyCode = e.getKeyCode(); switch( keyCode ) { case KeyEvent.VK_UP: // handle up break; case KeyEvent.VK_DOWN: // handle down break; case KeyEvent.VK_LEFT: // handle left break; case KeyEvent.VK_RIGHT : // handle right break; } }
Declare the class containing the event: class MyClass { public event EventHandler MyEvent; public void Method() { OnEvent(); } private void OnEvent() { if (MyEvent != null) { MyEvent(this, EventArgs.Empty); } } } Use it like this: MyClass myObject = new MyClass(); myObject.MyEvent += new EventHandler(myObject_MyEvent); myObject.Method();
Add following in your AndroidManifest.xml <application android:name=”MyApplication” android:debuggable=”true” android:icon=”@drawable/icon” android:label=”@string/app_name”> </application> then your onCreate() will get fired.
If you want to send an event between services/directives use broadcast: $rootScope.$broadcast(‘buttonPressedEvent’); And recieve it like this: $rootScope.$on(‘buttonPressedEvent’, function () { //do stuff })
The event object that is passed by jQuery is a wrapper around the native event object. The bubbling happens at the javascript/browser level and hence the native event object seems to be shared among all the event handlers. $(‘div’).click(function(e) { e.originalEvent.attribute = (e.originalEvent.attribute || “”) + ” ” + $(this).prop(“className”); alert(e.originalEvent.attribute); }); Tested in Chrome, … Read more
To preserve cursor position, backup input.selectionStart before changing value. The problem is that WebKit reacts to keydown and Opera prefers keypress, so there’s kludge: both are handled and throttled. var ignoreKey = false; var handler = function(e) { if (ignoreKey) { e.preventDefault(); return; } if (e.keyCode == 38 || e.keyCode == 40) { var pos … Read more
