event-handling

I'm working in C# and my workplace has some code standards. One of them is that each event handler we connect (such as KeyDown ) must be disconnected in the Dispose method. Is there any good reason for that? Unless you expect the publisher of the event to outlive the subscriber, there's no reason to remove the event handler, no. This is one of those topics where folk lore has grown up. You really just need to think about it in normal terms: the publisher (e.g. the button) has a reference to the subscriber. If both the publisher and the subscriber will be eligible for garbage collection at the

I'm using Jquery mousewheel plugin and I would like like to be able to detect when the user has finished using the wheel. Similar functionality as the stop: event in the draggable stuff. Can somebody point me to the right direction? 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: $("#myElem").mousewheel(function() { clearTimeout($.data(this, 'timer'));

I have an element with an onclick method. I would like to activate that method (or: fake a click on this element) within another function. Is this possible? If you're using JQuery you can do: $('#elementid').click(); Once you have selected an element you can call click() document.getElementById('link').click(); see: https://developer.mozilla.org/En/DOM/Element.click I don't remember if this works on IE, but it should. I don't have a windows machine nearby. I could be misinterpreting your question, but, yes, this is possible. The way that I would go about doing it is this: var oElement =

I've got code similar to the following... <p><label>Do you have buffet facilities?</label> <asp:RadioButtonList ID="blnBuffetMealFacilities:chk" runat="server"> <asp:ListItem Text="Yes" Value="1"></asp:ListItem> <asp:ListItem Text="No" Value="0"></asp:ListItem> </asp:RadioButtonList></p> <div id="HasBuffet"> <p><label>What is the capacity for the buffet?</label> <asp:RadioButtonList ID="radBuffetCapacity" runat="server"> <asp:ListItem Text="Suitable for upto 30 guests" value="0 to 30"></asp:ListItem> <asp:ListItem Text="Suitable for upto 50 guests" value="30 to 50"></asp:ListItem> <asp

Can someone explain me why is there a difference in the order in which the event handlers are being executed depending on how they have been attached? In the example below I'm using the .on() and .addEventListener() methods to handle a specific event on different DOM elements. jsfiddle : http://jsfiddle.net/etsS2/ I thought that in this particular example the order in which the event handlers are going to be executed will depend on the event-bubbling - so starting from the original event target and moving up to the document element. document.getElementById('outer').addEventListener('mouseup',
