event-handling

This question is asked often, but never really answered well. Let's see if we can remedy it! Event Propagation Google allows you to bind to events in a Google Map View via their API using event handlers . Sometimes you may bind your event handler to an event that Google itself is already bound to. Thus, when your event fires and does whatever you told it to do you may find Google also doing its own little thing at the same time. Hmm, can I handle the event so my code runs, but stop the event from continuing on and firing Google's event handler? You sure can ! Welcome to Event Propagation (aka

Hi I'm creating a new audio tag element in Javascript this is the code: var audio = document.createElement("audio"); audio.setAttribute("id","myid"); audio.setAttribute("autoplay","autoplay"); document.body.appendChild(audio); before appending it to the body, I'd like to place an onended event handler, I tried something like this: audio.onended = foo; where foo is something like: function foo(){alert('Hola')} and audio.setAttribute("onended","foo()"); in both case it didn't work. In the first case the audio tag is appended without any onended event handler; while in the second case the audio

I'm using safari webkit's engine together with HTML5 and JS to create an offline application now I'm using the sessionStorage array to store status of my application(simulation). the storage data works fine with the inspector the functions work fine it's the event handler that isn't responding the test preformd by Anurag at http://jsfiddle.net/pvRgH/ also doesn't work here window.addEventListener('storage', storageEventHandler, false); function storageEventHandler(evt){ alert("storage event called key: " + evt.key ); switch(evt.key){ case 'bat1': case 'bat2': batteryDCMeter(); break; case

I have a jQuery onClick handler, writed with an anonymous function like that: $("#selector").on("click" function(){ // do something }) I would generalize the anonymous function extracting the logic in a named function, that drive me to something like: $("#selector").on("click" namedFunction()) function namedFunction(){ // do something } To me seemed a good solution. But there's a drawback since the namedFunction is executed as soon script is loaded. Here you can test the bad behaviour. Just pass the reference of that function itself. Try, $("#selector").on("click", namedFunction); You don't

let say have element like this <div class="watch-me" style="display: none;">Watch Me Please</div> as we can see the element above style is display: none , how can i make script to watch this element. when that element style is change to display: block then there is some code will be trigger. many thanks... Jacob Relkin As far as I know, the only way to do this would be with a timer. I created a small jQuery plugin (yes, right here, right now) that does this against a jQuery set: EDIT this plugin is now on GitHub: https://github.com/jacobrelkin/jquery-watcher $.fn.watch = function(property,

Let's just say that I have: public Boolean booleanValue; public bool someMethod(string value) { // Do some work in here. return booleanValue = true; } How can I create an event handler that fires up when the booleanValue has changed? Is it possible? Avoid using public fields as a rule in general. Try to keep them private as much as you can. Then, you can use a wrapper property firing your event. See the example: class Foo { Boolean _booleanValue; public bool BooleanValue { get { return _booleanValue; } set { _booleanValue = value; if (ValueChanged != null) ValueChanged(value); } } public event
