  • Detecting a image 404 in javascript.

    - by xal
    After a user uploads a file we have to do some additional processing with the images such as resizing and upload to S3. This can take up to 10 extra seconds. Obviously we do this in a background. However, we want to show the user the result page immediately and simply show spinners in place until the images arrive in their permanent home on s3. I'm looking for a way to detect that a certain image failed to load correctly (404) in a cross browser way. If that happens, we want to use JS to show a spinner in it's place and reload the image every few seconds until it can be successfully loaded from s3.

  • access exception when invoking method of an anonymous class using java reflection

    - by Asaf David
    Hello I'm trying to use an event dispatcher to allow a model to notify subscribed listeners when it changes. the event dispatcher receives a handler class and a method name to call during dispatch. the presenter subscribes to the model changes and provide a Handler implementation to be called on changes. Here's the code (I'm sorry it's a bit long). EventDispacther: package utils; public class EventDispatcher<T> { List<T> listeners; private String methodName; public EventDispatcher(String methodName) { listeners = new ArrayList<T>(); this.methodName = methodName; } public void add(T listener) { listeners.add(listener); } public void dispatch() { for (T listener : listeners) { try { Method method = listener.getClass().getMethod(methodName); method.invoke(listener); } catch (Exception e) { System.out.println(e.getMessage()); } } } } Model: package model; public class Model { private EventDispatcher<ModelChangedHandler> dispatcher; public Model() { dispatcher = new EventDispatcher<ModelChangedHandler>("modelChanged"); } public void whenModelChange(ModelChangedHandler handler) { dispatcher.add(handler); } public void change() { dispatcher.dispatch(); } } ModelChangedHandler: package model; public interface ModelChangedHandler { void modelChanged(); } Presenter: package presenter; public class Presenter { private final Model model; public Presenter(Model model) { this.model = model; this.model.whenModelChange(new ModelChangedHandler() { @Override public void modelChanged() { System.out.println("model changed"); } }); } } Main: package main; public class Main { public static void main(String[] args) { Model model = new Model(); Presenter presenter = new Presenter(model); model.change(); } } Now, I except to get the "model changed" message. However, I'm getting an java.lang.IllegalAccessException: Class utils.EventDispatcher can not access a member of class presenter.Presenter$1 with modifiers "public". I understand that the class to blame is the anonymous class i created inside the presenter, however I don't know how to make it any more 'public' than it currently is. If i replace it with a named nested class it seem to work. It also works if the Presenter and the EventDispatcher are in the same package, but I can't allow that (several presenters in different packages should use the EventDispatcher) any ideas?

  • Simulating mouse clicks on Mac OSX does not work for some applications.

    - by Thomi
    Hi, I'm writing an App for Mac OSX 10.6 and later in C++. One part of theapp needs to simulate mouse movement and mouse clicks. I do this currently by posting CGEvent objects using CGEventPost(kCGHIDEventTap, event);. This works, for the msot part - I can simulate mouse movement and clicks just fine, but it seems to fail in some areas. For example: In Mozilla firefox & Safari, I can click on all the menus, but cannot click on a link within a website. When I try, the link is highlighted, but the browser never follows the link. However, I can right-click on a link, select "open link in new tab", and everything works as expected. I can click on the "Dashboard" icon to brink up the dashboard, but I cannot click on the "i" button on any of the dashboard widgets. This inconsistency is along application boundaries - Does anyone have any idea what the cause might be?

  • prototype/javascript - firefox not firing keypress/keydown event unless focus is in textbox

    - by Chloraphil
    The following works fine on IE6, IE7, and chrome. Not working on ff 3.0.7. <html><head> <script src="prototype.js" type="text/javascript" ></script> <script type="text/javascript"> Event.observe(window, 'load', function(){ Event.observe(document.body, 'keydown', myEventHandler); alert('window load'); }); function myEventHandler(evt) { alert(evt); } </script> </head> <body > <input type="text" /><br><br> </body></html> EDIT: By "not working" I mean myEventHandler is not firing in firefox. EDIT2: Furthermore, it works fine when focus is on the input element. I want it fire for all keydowns.

  • VB.net Net after load event?

    - by themaninthesuitcase
    I need some way of knowing when a form has finished loading. My reasoning is I have a 2nd form that is loaded when this form loads. The code for this is called from form1.load. Form2 is currently being displayed behind form1 as I am guessing form1 calls an activate or similar at the end of the load so any Activate, BringToFront etc calls on from2 are over ridden. If you look at the code below I have tried adding frmAllocationSearch.Activate, frmAllocationSearch.BringToFront and Me.SendToBack after the call to ShowAlloactionSearchDialog() but these are all wasted as something is happening after the load event is fired to bring Me to the front. Code is: Private Sub Allocation_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load ShowAlloactionSearchDialog() End Sub Private Sub ShowAlloactionSearchDialog() If frmAllocationSearch Is Nothing OrElse frmAllocationSearch.IsDisposed Then frmAllocationSearch = New AllocationSearch frmAllocationSearch.MdiParent = Me.MdiParent frmAllocationSearch.Info = Me.Info frmAllocationSearch.Top = Me.Top frmAllocationSearch.Left = Me.Left + Me.Width - frmAllocationSearch.Width frmAllocationSearch.AllocationWindow = Me frmAllocationSearch.Show() Else If frmAllocationSearch.WindowState = FormWindowState.Minimized Then frmAllocationSearch.WindowState = FormWindowState.Normal frmAllocationSearch.Activate() End If End Sub

So I created a really simple program like: #include <iostream> #include <string> using namespace std; class superman { public: string punch(){return cout << "superman: I hit the bad guy!" << endl;}; }; int main() { superman clark; clark.punch(); cin.get(); } I want to add an event listner that would tell me when clark punched and cout something like "superman punched!". How to add such event listner and event function to my class?

  • Shortest way of attaching multiple DOM elements to one event handler using Jquery?

    - by Camsoft
    I need to attach a single event handler to multiple DOM elements using jQuery. I'm currently achieving this using jQuery's each() method. See below: $([elm1, elm2, elm3]).each(function() { this.click(eventHandler); }); I was wondering if there is a way to do this without using the each method and closure. I thought I would be able to do something like: $(elm1, elm2, elm3).click(eventHandler); This kind of statement works using Prototype.js but not in jQuery.The reason I ask the question is because after using both Prototype.js and jQuery I have found that jQuery requires simpler statements to achieve the same tasks in almost every area so I assume there must be a better way of doing this?

  • javascript textbox call event when value changes

    - by Senica Gonzalez
    I have a textbox, and whenever the value of the box changes, I want to check and see if 20 digits have been entered. I thought that I would use the onChange event, but this seems to be interpreted as the onBlur event on IE. So then I thought I would use onKeyDown, but the problem comes in if the user wants to paste a value into the field, then the function never gets called. There are no other form boxes so I can't rely on onBlur or expect that they will change focus ever. How do I do this? I just want to evaluate the value of the textbox everytime the value of the textbox changes. <input type="text" onKeyDown="myfunction()">
