  • 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.

  • NSView -(void)keyDown in console program

    - by Jonas Byström
    I'm not getting the -(void)keyDown callback on my inherited NSOpenGLView (note that mouseMoved does not work either though I do setAcceptsMouseMovedEvents:YES, but that is not an issue yet). It implements - (BOOL)acceptsFirstResponder { return YES; } but still no luck. My knowledgeable friend implied that it might have something to do with that the application is still a console application and not a bundled .app (I'm currently porting it). If so: is there some way to circumvent? Could the cause be something else? When I terminate my console application, I frequently see all my keypresses go to stdout so it does seem reasonable...

  • JQuery with css3 keydown keyCode = 37 and 39

    - by rayrule
    I have tested both ways. jquery animation and css3 transition, and css3 is a little bit faster. But i have a problem with the following code: $(document).keydown(function(e){ if (e.keyCode == 39) { var DocHeight = $(document).height(); $('.container').css("margin-top","-="+DocHeight) } }); if i hit twice on keyCode 39 (arrow to the right) than my transition is outer space. Does anyone has an solution for this thing? outer space maybe not the correct word. But the problem is. if i hit twice the arrow key i'll get the last request, in other words... animation is started, and another animation start from the position that i don't want. example: hit #1 margin-top is at 0px and goes to 1024px. but when i hit it twice the margin-top is at 23px, and it stops at 1047px. This is not what i want. It has to stop at 1024px. I hope so.

  • How to get keypressed, keydown events from DataGridView data cells

    - by extropy
    Hi. I need to recieve the key press events during cell editing in DataGridView control. From what I have found on the net the DataGridView is designed to pass all key events from DataGridView to the cell editing control and you cannot get these events easily. I found this peace of code http://www.codeproject.com/KB/grid/DataGridCellEvents.aspx that traps those events for DataGrid control, but that does not work for DataGridView.

  • VS 2010 breaks my keydown events

    - by Erik Karlsson
    I have a custom control, a groupbox, which reacts on key events on a assigned key. It is possible to remove this groupbox, as well as adding more dynamically. Havnt been any trouble in VS 2008 so far. Two days ago i installed VS 2010. And i started to get multiple event fireing, and removing a groupbox did not remove the specific key events attached to it. Where did it go wrong? I use -= on the events present in the gruopbox code to remove them before removing the groupbox.

  • Difficulty with jQuery and input keydown event

    - by Rosarch
    I am making a simple JavaScript enhanced list. I want it to be a list of inputs, each with an 'Add' and 'Remove' button. If the user clicks 'Add', a new li will be added. If the user clicks 'Remove', that li will be removed. It works fine, except for hitting "enter" in an <input>. Currently, it always causes the Remove.click event handler to fire, unless there's only one item in the list. I'm not sure why. How can I suppress this? Here is the complete jQuery. My attempt to fix the "enter" issue is commented out, and it doesn't work. I suspect that I could be designing this code better; if you see an improvement I'd love to hear it. function make_smart_list(list) { var ADD_CLASS = 'foo-widget-Add'; var REMOVE_CLASS = 'foo-widget-Remove'; var jq_list = $(list); jq_list.parents('form').submit(function() { return false; }); function refresh_handlers() { jq_list.find(sprintf('.%s, .%s', REMOVE_CLASS, ADD_CLASS)).unbind('click'); // jq_list.find('input').unbind('submit'); // // jq_list.find('input').submit(function() { // var jq_this = $(this); // var next_button = jq_this.nextAll('button'); // if (next_button.hasClass(ADD_CLASS)) { // next_button.nextAll('button').click(); // return; // } // // if (next_button.hasClass(REMOVE_CLASS)) { // return false; // } // // }); jq_list.find("." + REMOVE_CLASS).click(function() { var jq_this = $(this); jq_this.parent().remove(); refresh_handlers(); return false; }); jq_list.find("." + ADD_CLASS).click(function() { var jq_this = $(this); if (jq_this.prevAll('input').val() == '') { return; } jq_this.parent().clone().appendTo(jq_this.parent().parent()); jq_this.parent().next().find('input').val('').focus(); jq_this.removeClass(ADD_CLASS).addClass(REMOVE_CLASS); jq_this.text('Remove'); refresh_handlers(); return false; }); } refresh_handlers(); } (sprintf is another script I have.)

  • Javascript (JQuery) keyboard hijack problem

    - by user266564
    I'm making a typing tutor program using javascript. Everything is going well except that if activates browser hotkeys which disrupts the functionality of the program. When I press the single quote in Firefox it triggers "Quick find (links only)" short cut and in all browsers when I press space the page scrolls down a page. Everything is working fine outside of this. Here's the code in the head: <script type="text/javascript"> $(document).ready(function() { executeType(); }); </script> And the code I am using to capture the keyboard (simplified, but tested): function executeType() { $(document).keydown(function(event) { alert(event.keyCode); }); }

  • How do I close a form when the ESC key was hit, but only if no Control handled it?

    - by Gabriel
    I have a Form that closes itself when the ESC key is pressed, thanks to KeyPreview, ProcessKeyEventArgs, ProcessCmdKey or whatever. But I have a Control on that form that does very relevant things when ESC is pressed (it hides itself) and the Form should not be closed when that happens. The control uses the KeyDown event and sets the SuppressKeyPress flag to true, but that happens after the aforementioned form key preview, thus having no effect. Is there some sort KeyPostview ? How do I not close the form when a Control has a relevant use of a key hit ? Edit: The control handling ESC is a textbox embedded in a hand-maid ListView. The textbox appears when the user clicks a cell, enabling edition. To validate the new text, ENTER would be nice (that already works, as giving the focus to anything else). To cancel edition, ESC seems most natural.

  • How can I capture the keystroke that triggers "CellEndEdit" on a DataGridView in C#?

    - by Andy Stampor
    I have a DataGridView that is set to EditOnF2. I do some special processing of data in the CellEndEdit eventhandler that sets the value of the cell. I still want the functionality of the EditOnKeystrokeOrF2 of reverting to the original value when the Esc key is pressed. Unfortunately, at the CellEndEdit eventhandler, I don't see a way to tell what caused the CellEndEdit event to be fired. I only want to change the value of the cell if the Esc key is not pressed. How can I tell if it was or not? Edit: It is worth noting that the KeyDown event does not get fired when the cell is being edited, nor for the final ending keystroke. Edit2: I have tried the KeyPreview suggestion, but the form still does not capture the Escape key being pressed. Edit3: I've been experimenting with trying to get this working. I originally posted some of the following as a separate post, but feel it might be more relevant to include it here. I have a cell in a DataGridView that is now set to EditProgrammatically. To capture the keystroke that starts an edit, I am setting the cell.Value equal to the keystroke. However, this ruins the "Escape" functionality of the cell - when you press escape, instead of reverting to the original value, it reverts to the keystroke that I programmatically inserted into the cell. I believe that if I could set the "EditedFormattedValue" on a cell, this would be where I want to put my keystroke value, however this appears to be read only. How can I accomplish what I am attempting? An example to clarify: If the cell has a value of "54.3" in it, and I press the "9" key, it begins editing the cell and places a "9" there. If I hit Escape, instead of reverting to "54.3" it reverts to "9". What I want is for it to return to its original value of "54.3". So, I am trying to tackle this issue from both the beginning and the end. I think the real problem is that I am overwriting the original value and have no way to determine if I should revert it or not. Edit4: It looks like CellValidating might be worth using, but I am seeing strange behavior when I experiment with it. In a new project, I create the DataGridView and register for the various events and see that CellValidating is fired before the CellEndEdit. However, in my project where I am trying to get this to work, CellEndEdit is firing BEFORE CellValidating. Any ideas on what the difference might be?

  • Javascript keyup doesn't work as expected, it executes in instances where I have not removed my fing

    - by Binni
    I'm trying to create a simple game in javascript and I'm stuck on how to deal with keys. Small example: function keyUpEvent(event) { alert(event.keyCode); } window.addEventListener("keyup", keyUpEvent, false); I'm running Ubuntu 9.10 and testing it in Firefox 3.5 and Chromium. If I press and release a button instantly I get an alert, which is to be expected, but when I press and hold a button I get a small pause and then a series of alert windows, the expected result is that I only get an alert window when I remove my finger from a button. I reason it has something to do with the fact that when I press and hold a button in a text area for example I get one character, small pause, and then a series of characters: dddddddddddddddd. I believe it's possible to get around this or do it more right or whatever since this game for example: http://bohuco.net/testing/gamequery/pong.html seams not to be affected by this. But I notice if I try out the jquery keyup demo ( api.jquery.com/keyup/ ) I get the same problem. How can I implement basic game key event handling?

  • Can jQuery dynamically change a "username" field based on a "name" field?

    - by SoulieBaby
    Hi all, basically I have two input fields, "name" and "username". The idea is that the "username" field will change depending on what is entered into the "name" field - dynamically. I also need the username field to be in lowercase only and to change spaces into dashes. I was thinking using onkeydown but I couldn't get it to do anything. I've been looking around, but can't seem to find what I'm looking for. Anyone got any ideas? <input type="text" name="name" id="name" class="field" /> <input type="text" name="username" id="username" class="field" /> ^^ basic form inputs.

I want it so both keys can be pressed (or held down)at the same time and both events will trigger. Thanks, Nevik

  • How dangerous is e.preventDefault();, and can it be replaced by keydown/mousedown tracking?

    - by yc
    I'm working on a tracking script for a fairly sophisticated CRM for tracking form actions in Google Analytics. I'm trying to balance the desire to track form actions accurately with the need to never prevent a form from not working. Now, I know that doing something like this doesn't work. $('form').submit(function(){ _gaq.push('_trackEvent', 'Form', 'Submit', $(this).attr('action')) }); The DOM unloads before this has a chance to process. So, a lot of sample code recommends something like this: $('form').submit(function(e){ e.preventDefault(); var form = this; _gaq.push('_trackEvent', 'Form', 'Submit', $(this).attr('action')); //...do some other tracking stuff... setTimeout(function(){ form.submit(); }, 400); }); This is reliable in most cases, but it makes me nervous. What if something happens between e.preventDefault();and when I get around to triggering the DOM based submit? I've totally broken the form. I've been poking around some other analytics implementations, and I've noticed something like this: $('form').mousedown(function(){ _gaq.push('_trackEvent', 'Form', 'Submit', $(this).attr('action')); }); $('form').keydown(function(e){ if(e.which===13) //if the keydown is the enter key _gaq.push('_trackEvent', 'Form', 'Submit', $(this).attr('action')); }); Basically, instead of interrupting the form submit, preempting it by assuming that if someone is mousing down or keying down on Enter, than that form is submitted. Obviously, this will result in a certain amount of false positives, but it completely eliminates use of e.preventDefault();, which in my mind eliminates the risk that I might ever prevent a form from successfully submitting. So, my question: Is it possible to take the standard form tracking snippet and prevent it from ever fully preventing the form from submitting? Is the mousedown/keydown alternative viable? Are there any submission cases it may miss? Specifically, are there other ways to end up submitting besides the mouse and the keyboard enter? And will the browser always have time to process javascript before beginning to unload the page?

  • Why does KeyDown event not have access to the current value of bound variable?

    - by Edward Tanguay
    In the example below: I start program, type text, click button, see text above. Press ENTER see text again. BUT: I start program, type text, press ENTER, see no text. It seems that the KeyDown event doesn't get access to the current value of the bound variable, as if it is always "one behind". What do I have to change so that when I press ENTER I have access to the value that is in the textbox so I can add it to the chat window?
