  • jQuery attach function to 'load' event of an element

    - by Miguel Ping
    Hi, I want to attach a function to a jQuery element that fires whenever the element is added to the page. I've tried the following, but it didn't work: var el = jQuery('<h1>HI HI HI</H1>'); el.one('load', function(e) { window.alert('loaded'); }); jQuery('body').append(el); What I really want to do is to guarantee that another jQuery function that is expecting some #id to be at the page don't fail, so I want to call that function whenever my element is loaded in the page. To clarify, I am passing the el element to another library (in this case it's a movie player but it could be anything else) and I want to know when the el element is being added to the page, whether its my movie player code that it is adding the element or anyting else.

  • How to push oath token to LocalStorage or LocalSession and listen to the Storage Event? (SoundCloud Php/JS bug workaround)

    - by afxjzs
    This references this issue: Javascript SDK connect() function not working in chrome I asked for more information on how to resolve with localstorage and was asked to create a new topic. The answer was "A workaround is instead of using window.opener, push the oauth token into LocalStorage or SessionStorage and have the opener window listen to the Storage event." but i have no idea how to do that. It seems really simple, but i don't know where to start. I couldn't find an relevant examples. thanks for your help!

  • Can I interrupt javascript code and then continue on a keystroke?

    - by Brian Ramsay
    I am porting an old game from C to Javascript. I have run into an issue with display code where I would like to have the main game code call display methods without having to worry about how those status messages are displayed. In the original code, if the message is too long, the program just waits for the player to toggle through the messages with the spacebar and then continues. This doesn't work in javascript, because while I wait for an event, all of the other program code continues. I had thought to use a callback so that further code can execute when the player hits the designated key, but I can't see how that will be viable with a lot of calls to display.update(msg) scattered throughout the code. Can I architect things differently so the event-based, asynchronous model works, or is there some other solution that would allow me to implement a more traditional event loop? Am I making sense? Example: // this is what the original code does, but obviously doesn't work in Javascript display = { update : function(msg) { // if msg is too long // wait for user input // ok, we've got input, continue } }; // this is more javascript-y... display = { update : function(msg, when_finished) { // show part of the message $(document).addEvent('keydown', function(e) { // display the rest of the message when_finished(); }); } }; // but makes for amazingly nasty game code do_something(param, function() { // in case do_something calls display I have to // provide a callback for everything afterwards // this happens next, but what if do_the_next_thing needs to call display? // I have to wait again do_the_next_thing(param, function() { // now I have to do this again, ad infinitum } }

  • Closing InfoWindow with Google Maps API V3

    - by Oscar Godson
    I've seen the other posts, but they dont have the markers being looped through dynamically like mine. How do I create an event that will close the infowindow when another marker is clicked on using the following code? $(function(){ var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 10, center: latlng, disableDefaultUI:false, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $.getJSON('api',function(json){ for (var property in json) { if (json.hasOwnProperty(property)) { var json_data = json[property]; var the_marker = new google.maps.Marker({ title:json_data.item.headline, map:map, clickable:true, position:new google.maps.LatLng( parseFloat(json_data.item.geoarray[0].latitude), parseFloat(json_data.item.geoarray[0].longitude) ) }); function buildHandler(map, marker, content) { return function() { var infowindow = new google.maps.InfoWindow({ content: '<div class="marker"><h1>'+content.headline+'</h1><p>'+content.full_content+'</p></div>' }); infowindow.open(map, marker); }; } new google.maps.event.addListener(the_marker, 'click',buildHandler(map, the_marker, {'headline':json_data.item.headline,'full_content':json_data.item.full_content})); } } }); });

  • Are delegates copied during assignment to an event?

    - by Sir Psycho
    Hi, The following code seems to execute the FileRetrieved event more than once. I thought delegates were a reference type. I was expecting this to execute once. I'm going to take a guess and say that the reference is being passed by value, therefore copied but I don't like guesswork :-) public delegate void DirListEvent<T>(T dirItem); void Main() { DirListEvent<string> printFilename = s => { Console.WriteLine (s); }; var obj = new DirectoryLister(); obj.FileRetrieved += printFilename; obj.FileRetrieved += printFilename; obj.GetDirListing(); } public class DirectoryLister { public event DirListEvent<string> FileRetrieved; public DirectoryLister() { FileRetrieved += delegate {}; } public void GetDirListing() { foreach (var file in Directory.GetFiles(@"C:\")) { FileRetrieved(file); } } }

  • how to attach window.close to cntrl+w keypress event in a xul window?

    - by Erik Vold
    I have a XUL window, and I want the cntrl+w hotkey to close the window, but when I attach: window.addEventListener("keypress", function(ev) { GM_log("onkeypress handler: \n" + "keyCode property: " + ev.keyCode + "\n" + "which property: " + ev.which + "\n" + "charCode property: " + ev.charCode + "\n" + "Character Key Pressed: " + String.fromCharCode(ev.charCode) + "\n"); }, true); to the page, it treats pressing 'w' and 'cntrl+w' the same, charCode 119.. how can I determine that cntrl+w was pressed so that I may window.close() ?

  • How to pass an event to a method and then subscribe to it?

    - by Ryan Peschel
    Event Handler public void DeliverEvent(object sender, EventArgs e) { } #1: This Works public void StartListening(Button source) { source.Click += DeliverEvent; } #2: And so does this.. public void StartListening(EventHandler eventHandler) { eventHandler += DeliverEvent; } But in #2, you cannot call the method because if you try something like this: StartListening(button.Click); You get this error: The event 'System.Windows.Forms.Control.Click' can only appear on the left hand side of += or -= Is there any way around that error? I want to be able to pass the event and not the object housing the event to the StartListening method.

  • Transform any JavaScript function into a page event

    - by Laith
    I need to be able to achieve the following (one way or another): function ShowContent() {} document.onShowContent = function () { // anything I want to happen.... } What I'm trying to do is to add a kind of listener to me Advertisement code on the page that will auto refresh the ad slot when a specific function is called. Instead of having that function "ShowContent()" directly refresh the ad code, I want the ad code to refresh if it detects that "ShowContent()" has been called. Thanks.

  • Custom Tag implementation issue

    - by Appps
    I have a custom tag as follows. repeat and heading tag have doAfterBody method implemented. <csajsp:repeat reps="5"> <LI> <csajsp:heading bgColor="BLACK"> White on Black Heading </csajsp:heading> </LI> </csajsp:repeat> /* Repeat tag Class*/ public void setReps(String repeats) { System.out.println("TESTING"+repeats); //sets the reps variable. } public int doAfterBody() { System.out.println("Inside repeate tag"+reps); if (reps-- >= 1) { BodyContent body = getBodyContent(); try { JspWriter out = body.getEnclosingWriter(); System.out.println("BODY"+body.getString()); out.println(body.getString()); body.clearBody(); // Clear for next evaluation } catch(IOException ioe) { System.out.println("Error in RepeatTag: " + ioe); } return(EVAL_BODY_TAG); } else { return(SKIP_BODY); } } /* Class of Heading tag */ public int doAfterBody() { System.out.println("inside heading tag"); BodyContent body = getBodyContent(); System.out.println(body.getString()); try { JspWriter out = body.getEnclosingWriter(); out.print("NEW TEXT"); } catch(IOException ioe) { System.out.println("Error in FilterTag: " + ioe); } // SKIP_BODY means I'm done. If I wanted to evaluate // and handle the body again, I'd return EVAL_BODY_TAG. return(SKIP_BODY); } public int doEndTag() { try { JspWriter out = pageContext.getOut(); out.print("NEW TEXT 2"); } catch(IOException ioe) { System.out.println("Error in HeadingTag: " + ioe); } return(EVAL_PAGE); // Continue with rest of JSP page } The order in which SOP are printed is 1) Setter method of csajsp:repeat is called. 2) White on Black Heading is printed. ie doAfterBody of csajsp:heading tag is called. I don't know why it is not calling doAfterBody of csajsp:repeat tag. Please help me to understand this. Thanks in advance.

  • VS/C#: Can I be notified of every event that gets handled while debugging?

    - by Daniel I-S
    I am currently troubleshooting a large and unwieldy GUI-based tool in Visual Studio, and was wondering whether there is any way to get some kind of notification (either by writing to the console or through a third-party tool) whenever any handled event occurs. This would make it a lot easier to track down what precisely is going on while I am interacting with this beast. Is there an 'on any event being handled' event I can handle, or some kind of add-in for VS which would make this possible?

  • IE not triggering keyboard event on a form with ONE FIELD

    - by raj
    I'm seeing my Friend's code here... <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> Check action </TITLE> <script> function detectEvent(){ if(window.event.keyCode==13) { alert("you hit return!"); } } </script> </HEAD> <BODY> <form name="name1" onkeyup="detectEvent()" action="page2.html"> <p> Field1 <input type="text" id="text1"/> </p> </form> </BODY> </HTML> and when he tried entering a value in the textbox and pressed enter, it did not call the detectEvent(). I said, it'll always call onSubmit on enter button..... and he surprised me, <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <TITLE> Check action </TITLE> <script> function detectEvent(){ if(window.event.keyCode==13) { alert("you hit return!"); } } </script> </HEAD> <BODY> <form name="name1" onkeyup="detectEvent()" action="page2.html"> <p> Field1 <input type="text" id="text1"/> </p> <p> Field1 <input type="text" id="text2"/> </p> </form> </BODY> </HTML> Now press enter, The function gets called..... Why so!? Why onKeyUp not called on forms with just one field.!!! am i missing something?

  • WPF create a list of controls that can be scrolled via the mouse but still remain functional

    - by Mark
    I have a list of controls that I am displaying via a WrapPanel and it horizontally oriented. I have implemented a "Click and Drag" scrolling technique so that the user scrolls with the mouse via clicking and dragging. Like so: <Canvas x:Name="ParentCanvas" PreviewMouseDown="Canvas_MouseDown" MouseMove="Canvas_MouseMove"> <WrapPanel> <WrapPanel.RenderTransform> <TranslateTransform /> </WrapPanel.RenderTransform> <!-- controls are all in here ... --> </WrapPanel> </Canvas> Then in the code behind: private Point _mousePosition; private Point _lastMousePosition; private void Canvas_MouseDown(object sender, MouseButtonEventArgs e) { _lastMousePosition = e.GetPosition(ParentCanvas); e.Handled = true; } private void Canvas_MouseMove(object sender, MouseEventArgs e) { _mousePosition = e.GetPosition(ParentCanvas); var delta = _mousePosition - _lastMousePosition; if(e.LeftButton == MouseButtonState.Pressed && delta.X != 0) { var transform = ((TranslateTransform)_wrapPanel.RenderTransform).Clone(); transform.X += delta.X; _wrapPanel.RenderTransform = transform; _lastMousePosition = _mousePosition; } } This all works fine But what I want to do is make it so that when a users clicks to drag, the items within the WrapPanel dont respond (i.e. the user is only browsing), but when the user clicks (as in a full click) then they do respond to the click. Just like how the iphone works, when you press and drag directly on an app, it does not open the app, but rather scrolls the screen, but when you tap the app, it starts... I hope this makes sense. Cheers, Mark

  • Customise a control in dynamics crm

    - by webturner
    I've written code that can make a phone dial a number from a function call, that's done and dusted. What I would like to achieve is adding a Dial button to each phone number field on the forms in Dynamics CRM. Eventually this could also create a new phone record fill in the basic details and show it to the user to enter notes and an outcome for the phone call, and perhaps some other workflow bits to schedule the next call. Can I put a custom control on a standard form in place of the standard control. I'm assuming it would have to be an IFrame to an asp.net page, that pulls in the record id, and the field name, looks up the number to show in a text box, and passes the number to the DialNumber function. Hey presto... I assume its not going to be that easy... Has anyone tried this before, what's the process, what are the gotchas?

  • Interrupting Prototype handler, alert() vs event.stop()

    - by lxs
    Here's the test page I'm using. This version works fine, forwarding to #success: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html><head> <script type="text/javascript" src="prototype.js"></script> </head><body> <form id='form' method='POST' action='#fail'> <button id='button'>Oh my giddy aunt!</button> <script type="text/javascript"> var fn = function() { $('form').action = "#success"; $('form').submit(); } $('button').observe('mousedown', fn); </script> </form> </body></html> If I empty the handler: var fn = function() { } The form is submitted, but of course we are sent to #fail this time. With an alert in the handler: var fn = function() { alert("omg!"); } The form is not submitted. This is awfully curious. With event.stop(), which is supposed to prevent the browser taking the default action: var fn = function(event) { event.stop(); } We are sent to #fail. So alert() is more effective at preventing a submission than event.stop(). What gives? I'm using Firefox 3.6.3 and Prototype 1.6.0.3. This behaviour also appears in Prototype 1.6.1.

  • Event problems with FF

    - by s4v10r
    Hi all :) Made this sweet little script to auto change fields after input. Works nicely in IE, Chrome and Safari, but not in FF or opera. JS code: function fieldChange(id, e){ var keyID = (window.event) ? event.keyCode : e.keyCode; if (document.getElementById(id).value.length >= 2){ if (keyID >= 48 && keyID <= 57 || keyID >= 96 && keyID <= 105){ switch(id){ case "textf1": document.getElementById("textf2").focus(); break; case "textf2": document.getElementById("textf3").focus(); break; case "textf3": if (document.getElementById(id).value.length >= 4){ document.getElementById("nubPcode").focus(); } break; } } } HTML: <div class="privateOrderSchema"> <input type="text" id="textf1" name="textf1" maxlength="2" size="4" onKeyUp="fieldChange('textf1')"/>- <input type="text" id="textf2" name="textf2" maxlength="2" size="4" onKeyUp="fieldChange('textf2')" />- <input type="text" id="textf3" name="textf3" maxlength="4" size="5" onKeyUp="fieldChange('textf3')" /> </div> <div class="privateOrderSchema"> <input type="text" id="nubPcode" name="nubPcode" size="4" maxlength="4" /> <br /> </div> Does anybody know how to send the "e" var in this scenario? Tnx all :D ur gr8!

  • Using jQuery's animate(), if the clicked on element is "<a href="#" ...> </a>", the fucntion should

    - by Jian Lin
    I was reading jQuery's page for animate() http://api.jquery.com/animate/ Its examples don't mention about if using <a href="#" id="clickme">click me</a> ... $('#clickme').click(function() { $('#someDiv').animate({left: "+=60"}); }) we actually still have to return false like in the old days? $('#clickme').click(function() { $('#someDiv').animate({left: "+=60"}); return false; }) (but then, those examples didn't use a <a> for the "click me"... but used something else. Otherwise the page will jump back to the beginning of the page? Does jQuery have a more elegant or magical way of doing it?

  • Accepting more simultaneous keyboard inputs

    - by unknownthreat
    Sometimes, a normal computer keyboard will only accept user's inputs up to a certain key simultaneously. I got a logitech keyboard that can accept up to 3-4 key presses at the same time. The computer does not accept any more input if you press more than 4 keys for this keyboard. And it also depends on certain areas of your keyboard as well. Some locations allow more key to be pressed (like the arrow keys), while some locations permit you to press only 1-2 keys. This also differs from keyboard to keyboard as well. Some older keyboards only accept up 1-2 keys. This isn't problematic with usual office work, but when it comes to gaming. For instance, imagine a platform game, where you have to jump, attack, and control direction at the same time. This implies several key presses and some keyboards cannot accept such simultaneous input. However, I've tried this on several games and the amount of possible keyboard inputs seem to be also different. Therefore, we have two issues: Keyboards have different amount of simultaneous inputs. Some games can accept more keyboard inputs than other games. At first, I thought this is hardware only problem, but why do some programs behave differently? Why some programs can accept more keyboard inputs than other programs? So how can we write our programs to accept more keyboard inputs?

  • Intercept windows open file

    - by HyLian
    Hello, I'm trying to make a small program that could intercept the open process of a file. The purpose is when an user double-click on a file in a given folder, windows would inform to the software, then it process that petition and return windows the data of the file. Maybe there would be another solution like monitoring Open messages and force Windows to wait while the program prepare the contents of the file. One application of this concept, could be to manage desencryption of a file in a transparent way to the user. In this context, the encrypted file would be on the disk and when the user open it ( with double-click on it or with some application such as notepad ), the background process would intercept that open event, desencrypt the file and give the contents of that file to the asking application. It's a little bit strange concept, it could be like "Man In The Middle" network concept, but with files instead of network packets. Thanks for reading.
