event-handling

Code: $('#Inputfield').keyup(function(e) { if(e.which == 13) { functionXyz(); } else { functionZyx(); } }); $(document).keyup(function(exit) { if (exit.keyCode == 27) { functionZzy(); } }); Question: How to remove the keyup event handler of keyCode == 27 and keep the other $(document).keyup event handlers intact? You have to use a named function so you can reference that specific handler when calling .unbind() , like this: function keyUpFunc(e) { if (e.keyCode == 27) { functionZzy(); } } $(document).keyup(keyUpFunc); Then later when unbinding: $(document).unbind("keyup", keyUpFunc); Your are

My HTML: <div id="x" onclick="clickHandler(event)"> <div id="button1">This turns green</div> <div id="button2">This turns blue</div> </div> So first of all, why am I supposed to be passing "event" into the click handler and is event some kind of system keyword? Also, since the click handler is identified on the container div, how do I know which button has been clicked? event is an Event object which is created automatically when an event is fired. Note that you don't have to call it event (I tend to call it simply e ). That Event object has a number of properties which describe the event it

I'm trying to embrace jQuery 100% with it's simple and elegant API but I've run into an inconsistency between the API and straight-up HTML that I can't quite figure out. I have an AJAX file uploader script (which functions correctly) that I want to run each time the file input value changes. Here's my working code: <input type="file" size="45" name="imageFile" id="imageFile" onchange="uploadFile()"> When I convert the onchange event to a jQuery implementation: $('#imageFile').change(function(){ uploadFile(); }); the result isn't the same. With the onchange attribute the uploadFile() function

I'm having a tough time understanding the difference between various methods of the com.google.gwt.core.client.Scheduler interface, specifically, the scheduleDeferred , scheduleFinally , and scheduleIncremental methods. I'm hampered in my understanding, I think, by my unfamiliarity with the browser event processing loop, to which the Scheduler documentation refers. Would you please explain how these methods differ from each other, and how they work in relation to the browser event loop? JavaScript (in a browser) is single threaded. The event loop model means, we're always in exactly one of two

I have the following asp.net textbox control. <asp:TextBox ID="txtAdd" runat="server" /> After the user writes something in this textbox and presses the ENTER key, I want to run some code from codebehind. What should I do? Using jQuery I captured ENTER key and fired some hidden button event $(document).ready(function(){ $(window).keydown(function(e){ if(e.keyCode == 13) $('#<% addbtn.ClientID %>'.click(); }); }); Is there any better way ? ASPX: <asp:TextBox ID="TextBox1" clientidmode="Static" runat="server" onkeypress="return EnterEvent(event)"></asp:TextBox> <asp:Button ID="Button1" runat=

I am trying to figure out how to bind an event to dynamically created elements. I need the event to persist on the element even after it is destroyed and regenerated. Obviously with jQuery's live function its easy, but what would they look like implemented with native Javascript? Andrew Whitaker 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
