  • JQuery input elements

    - by codeasp
    I need to get all input elements within a div and then attach event handlers, so that whenever values change it updates a hidden field. Children elements within the div might already contain event handlers, if so the attach should chain it. Any help is much appreciated.

  • Loading HTML5 video on iPad via onclick event tied to a div

    - by joncys
    I'm developing an HTML5 application (a game), that automatically preloads 5 video files. I'm able to do so correctly on Safari for PC, so there are no overlooked problems with file formats, codecs or such. The load fails on an iPad. As an official guide for video on iOS puts it: This means the JavaScript play() and load() methods are also inactive until the user initiates playback, unless the play() or load() method is triggered by user action. In other words, a user-initiated Play button works, but an onLoad="play()" event does not. Does this mean, that I have no means to initiate the loading of video after a user initiated action, if that action hasn't been tied to a video element (user clicked on a regular div — I request loading and displaying of a video, compared to the user actually clicking on a video element to load and play that particular element)? Thanks for your help!

  • ASP.NET button_click not firing, after browser back button

    - by the berserker
    I have a ASPX Page that contains several user controls, which are loaded dynamically after user interaction. On one of ascx I have a hidden button that is being clicked on some user actions (via button.click()), which works fine on 1st page load. But after the form is being submitted once, the other ascx is loaded. There if user clicks the back button and resubmits the 1st form (again via button.click()), button_clicked event on server does not fire again. Any thought?

  • Convert an interface's event from VB.Net to C#

    - by Jules
    Hi, I'm struggling to convert the below code to C#. Class Class1 Implements IMyInterface Public Event MyEvent(ByVal sender As Object, ByVal e As MyEventArgs) Implements IMyInterface.MyEvent Public Sub New() AddHandler Me.Slider.ValueChanged, AddressOf OnSliderValueChanged End Sub Private Sub OnSliderValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) RaiseEvent MyEvent(Me, New MyEventArgs()) End Sub End Class Here's what visual studio inserts when I ask it to implement for me: event EventHandler<MyEventArgs> IMyInterface.MyEvent { add { throw new NotImplementedException(); } remove { throw new NotImplementedException(); } } With a bit of googling I'm sure I can find out what to replace the NotImplementedException parts with but VS is still telling me that the definition is not implemented anyway.

  • View isn't scrolling back down after I dismiss the keyboard

    - by fmi
    I have a Tab Bar app. One of the views has a UITextView that is hidden by the keyboard when touched. I've set the view to scroll to account for the keyboard but it the view doesn't always return to it's original position after I dismiss the keyboard. Here is my code: //Scroll the view for keyboard - (void)viewWillAppear:(BOOL)animated { void (^keyBoardWillShow) (NSNotification *)= ^(NSNotification * notif) { NSDictionary* info = [notif userInfo]; NSValue* aValue = [info objectForKey:UIKeyboardFrameEndUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; float bottomPoint = (additionalView.frame.origin.y + additionalView.frame.size.height + 10); scrollAmount = keyboardSize.height - (self.view.frame.size.height - bottomPoint); if (scrollAmount > 0) { moveViewUp =YES; [self scrollTheView:YES]; } else moveViewUp = NO; }; [[NSNotificationCenter defaultCenter] addObserverForName:UIKeyboardWillShowNotification object:self.view.window queue:nil usingBlock:keyBoardWillShow]; void (^keyBoardWillHide) (NSNotification *)= ^(NSNotification * notif) { if (moveViewUp) [self scrollTheView:NO]; }; [[NSNotificationCenter defaultCenter] addObserverForName:UIKeyboardWillHideNotification object:self.view.window queue:nil usingBlock:keyBoardWillHide]; [super viewWillAppear:animated]; } - (void)viewWillDisappear:(BOOL)animated { [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil]; [super viewWillDisappear:animated]; } (void)scrollTheView:(BOOL)movedUp { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.3]; CGRect rect = self.view.frame; if (movedUp){ rect.origin.y -= scrollAmount; } else { rect.origin.y += scrollAmount; } self.view.frame = rect; [UIView commitAnimations]; }

  • How do I find the previous/default value of a radio button in JS?

    - by royrules22
    I'm not sure if this is even possible, but I figured I'd ask before clubbing togehter an ugly solution. What I have is a group of radio buttons and I want to trigger a function if the radio button value is changed. For example say there are three buttons X Y and Z with Y default selected. If a user clicks on an unselected button (i.e. X or Z) then the function gets triggered but if he/she clicks on Y (which is already selected) nothing happens. Naturally the best solution would be to fire the function on an onchange event but IE6 doesn't fire onchange until the focus is no longer on the element which is not satisfactory. So is there a way to know what the previous value of the radio button was or at least what its default value is? I could easily create an array of default values and check against that but I'm trying to reduce the overhead. Please no jQuery suggestions ;)

  • Implementing hoverIntent for Drop Down Menu (coming from click_event)

    - by stormeTrooper
    I've just recently started programming, I was hoping for some help. I have a drop down menu that was originally activated by click_event, however I want to now implement hoverIntent in order to make the menu drop. The issue I am having now is being able to use the menu, because whenever I invoke the menu now, once I leave the area that activates the menu, the menu closes. If you could explain to me like I'm five, I'd appreciate it, thanks :) The code I am using as follows: JavaScript: function setupUserConfigMenu() { $('.user_profile_btn').hoverIntent( function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }, function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }) } HTML: <li> <a href="<%= "#" %>" class="user_profile_btn" title="Your profile page"><%= truncate(current_user.full_name || current_user.name, :length => 28) %> <div class="arrow_down"></div></a> <ul id="user_settings_dropdown"> <li> <a href="<%= current_user.get_url(true) %>"> <%= image_tag current_user.get_thumb_url, :size => "30x30" %> <div> <%= truncate(current_user.full_name || current_user.name, :length => 40) %> <br> View profile </div> </a> </li> <div class="grey_line"></div> <li class="settings_list_item"> <%= link_to "Settings", edit_user_registration_path %> </li> <li class="settings_list_item"> <%= link_to "About", "/about" %> </li> <li class="settings_list_item"> <%= link_to "Logout", destroy_user_session_path, :method => :delete %> </li> </ul> </li>

  • When designing an event, is it a good idea to prevent listeners from being added twice?

    - by Matt
    I am creating an event-based API where a user can subscribe to an event by adding listener objects (as is common in Java or C#). When the event is raised, all subscribed listeners are invoked with the event information. I initially decided to prevent adding an event listener more than once. If a listener is added that already exists in the listener collection, it is not added again. However, after thinking about it some more, it doesn't seem that most event-based structures actually prevent this. Was my initial instinct wrong? I'm not sure which way to go here. I guess I thought that preventing addition of an existing listener would help to avoid a common programming error. Then again, it could also hide a bug that would lead to code being run multiple times when it shouldn't.

  • Swing: How do I run a job from AWT thread, but after a window was layed out?

    - by java.is.for.desktop
    My complete GUI runs inside the AWT thread, because I start the main window using SwingUtilities.invokeAndWait(...). Now I have a JDialog which has just to display a JLabel, which indicates that a certain job is in progress, and close that dialog after the job was finished. The problem is: the label is not displayed. That job seems to be started before JDialog was fully layed-out. When I just let the dialog open without waiting for a job and closing, the label is displayed. The last thing the dialog does in its ctor is setVisible(true). Things such as revalidate(), repaint(), ... don't help either. Even when I start a thread for the monitored job, and wait for it using someThread.join() it doesn't help, because the current thread (which is the AWT thread) is blocked by join, I guess. Replacing JDialog with JFrame doesn't help either. So, is the concept wrong in general? Or can I manage it to do certain job after it is ensured that a JDialog (or JFrame) is fully layed-out? Simplified algorithm of what I'm trying to achieve: Create a subclass of JDialog Ensure that it and its contents are fully layed-out Start a process and wait for it to finish (threaded or not, doesn't matter) Close the dialog I managed to write a reproducible test case: EDIT Problem from an answer is now addressed: This use case does display the label, but it fails to close after the "simulated process", because of dialog's modality. import java.awt.*; import javax.swing.*; public class _DialogTest2 { public static void main(String[] args) throws Exception { SwingUtilities.invokeAndWait(new Runnable() { final JLabel jLabel = new JLabel("Please wait..."); @Override public void run() { JFrame myFrame = new JFrame("Main frame"); myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); myFrame.setSize(750, 500); myFrame.setLocationRelativeTo(null); myFrame.setVisible(true); JDialog d = new JDialog(myFrame, "I'm waiting"); d.setModalityType(Dialog.ModalityType.APPLICATION_MODAL); d.add(jLabel); d.setSize(300, 200); d.setLocationRelativeTo(null); d.setVisible(true); SwingUtilities.invokeLater(new Runnable() { @Override public void run() { try { Thread.sleep(3000); // simulate process jLabel.setText("Done"); } catch (InterruptedException ex) { } } }); d.setVisible(false); d.dispose(); myFrame.setVisible(false); myFrame.dispose(); } }); } }

  • listener not being called

    - by deb
    I have a table with a button. When the button is clicked I call Modalbox.show (http://okonet.ru/projects/modalbox/) that displays a little form with another button. When the user clicks this second button, a listener is attached to an iframe in the form and the form is submitted to the server. The server does something then it should return back to the form and execute the listener function. This works fine on IE but not in Firefox (on Firefox it never comes back). Here it is the javascript function that is called when the user presses the second button (in the Modalbox) function attachFile() { //window.frames['upload_iframe'].name='upload_iframe'; iframe = document.getElementById('upload_iframe'); if (iframe.addEventListener)//FF iframe.addEventListener("load", iframeEventHandler, false); if (iframe.attachEvent)//IE iframe.attachEvent("onload", iframeEventHandler); // Set properties of form... form = document.getElementById('attchForm'); form.setAttribute("target","upload_iframe"); form.setAttribute("method","post"); form.setAttribute("enctype","multipart/form-data"); form.setAttribute("encoding","multipart/form-data"); // Submit the form... form.submit(); } I checked that it is adding the listener but somehow does not return to it. Any hints? Thanks deb
