• Before after select event validation and results with jquery

  - by richbyte

  I am using a javascript function (F) (jquery )which uses 3 select values selected by the user to calculates a value - R(result) R is a number ranging from (1 through 9), (11) and (22); I need 2 extra steps one before the calculation and one after. a. Before calculation takes place: Make sure all three select values are changed before function(F) takes place. If not prompt the user with a notice ( create dom element/ I am using jquery) b. After the value R is calculated show an element corresponding to the result e.g. if R is 1 show an element ( a predetermined "link" element corresponding to each result value) thanks a lot.

• Bootstarap: want to trigger some costum events on layout change

  - by DS_web_developer

  So, there are some events in my app that changes layout on my page (re-position of the elements)... mostly is done by bootstrap collapsing and fading (tabs, collapsibles, accordions)... I would like to fire an event whenever a change is about to happen and another when the change is done.. right now I came out with something like that $('.collapse').on("shown hidden", function(){ jQuery(myAPP).trigger("layoutchanged"); }); $('.collapse').on("show hide", function(){ jQuery(myAPP).trigger("layoutchanging"); }); and then... jQuery(myAPP).on("layoutchanging", function(e){ log("Start changing"); }); jQuery(myAPP).on("layoutchanged", function(e){ log("Layout changed"); }); it works for collapse and accordions OK. but on tabs, where the markup is like this: <ul class="nav nav-tabs can_deactivate"> <li><a href="#tab_1" data-toggle="tab">Open Tab 1</a></li> <li><a href="#tab_2" data-toggle="tab">Open Tab 2</a></li> </ul> <div class="tab-content"> <div class="tab-pane fade" id="tab_1"> Lorem ipsum </div> <div class="tab-pane fade" id="tab_2"> Lorem ipsum </div> </div> Works only on show, but not on hide... what can I do?

• Why are my event listeners firing more than once?

  - by Arms

  In my Flash project I have a movieclip that has 2 keyframes. Both frames contain 1 movieclip each. frame 1 - Landing frame 2 - Game The flow of the application is simple: User arrives on landing page (frame 1) User clicks "start game" button User is brought to the game page (frame 2) When the game is over, the user can press a "play again" button which brings them back to step 1 Both Landing and Game movieclips are linked to separate classes that define event listeners. The problem is that when I end up back at step 1 after playing the game, the Game event listeners fire twice for their respective event. And if I go through the process a third time, the event listeners fire three times for every event. This keeps happening, so if I loop through the application flow 7 times, the event listeners fire seven times. I don't understand why this is happening because on frame 1, the Game movieclip (and I would assume its related class instance) does not exist - but I'm clearly missing something here. I've run into this problem in other projects too, and tried fixing it by first checking if the event listeners existed and only defining them if they didn't, but I ended up with unexpected results that didn't really solve the problem. I need to ensure that the event listeners only fire once. Any advice & insight would be greatly appreciated, thanks!

• Reference the oncomplete event by an external java script function

  - by user339637

  Hi , I want to do some logic at the oncomplete attribute of the a4j:commandButton ,but my logic is too complicated , can I reference the code using a java script functions located in a external java-script file to have a better maintenance ? I found it has error because the JavaScript file cannot understand the EL expression . For example , originally I have , <a4j:commandButton id="btn1" action="#{MBena1.action1}" oncomplete="if( {MBena1.variable1}){Richfaces.showModalPanel('modelPanel1');};if (......) then "> I want to do something like this: <a4j:commandButton action="#{MBena1.action1}" oncomplete="Btn1OnComplete();"> the code is put inside the java script function Btn1OnComplete() which is located in a external java-script file. Thanks

• jQuery click event on image only fires once

  - by stephenreece@

  I created a view of thumbnails. When the user clicks, I want the real image to pop-up in a dialog. That works the first time, but once the jQuery 'click' fires on an thumbnail it never fires again unless I reload the entire page. I've tried rebinding the click events on the dialog close that that does not help. Here is my code: function LoadGalleryView() { $('img.gallery').each(function(){ BindImage($(this)); }); } function BindImage(image) { var src= image.attr('src'); var id= image.attr('id'); var popurl = src.replace("thumbs/", ""); image.hover(function(){ image.attr('style', 'height: 100%; width: 100%;'); }, function(){ image.removeAttr('style'); }); $('#'+id).live('click', function() { PopUpImage(popurl); }); } function CheckImage(img,html) { if ( img.complete ) { $('#galleryProgress').html(''); var imgwidth = img.width+35; var imgheight = img.height+65; $('<div id="viewImage" title="View"></div>').html(html).dialog( { bgiframe: true, autoOpen: true, modal: true, width: imgwidth, height: imgheight, position: 'center', closeOnEscape: true }); } else { $('#galleryProgress').html('<img src="images/ajax-loader.gif" /><br /><br />'); setTimeout(function(){CheckImage(img,html);},10); } } function PopUpImage(url) { var html = '<img src="'+url+'" />'; var img = new Image(); img.src = url; if ( ! img.complete ) { setTimeout(function(){CheckImage(img,html);},10); } } PopUpImage() only executes the first time an image is clicked and I cannot figure out how to rebind.

  All right so I am doing a javascript code for a login type form and it will lead you to a new page.

• How to override event on a UserControl

  - by Vadim

  Hello! I have a WinForms application (OwnerForm) with some UserControl. When textbox of UserControl is changed, I want to filter content of a OwnerForm. But how can I make it? I don't want to specify OwnerForm inside the user control. I know a solution to add manually handlers for MyUserControl.tb.TextChanged to some functions on a owner form, but I think it's bad way. I'll prefer to have overridable functions, but I can't imagine how to do it. Any suggestions? Thanks in advance,

• Event handler triggered twice instead of once

  - by kwokwai

  Hi all, I am sorry that I have asked two questions in a few minutes. In a html file, I got three child DIV tags in a parent DIV tag: <div id="container"> <div id="frag-123">123</div> <div id="frag-124">124</div> <div id="frag-125">125</div> </div> Now when I click either the three child DIV tags, I will see two alert boxes pop up instead of one: The first alert box will show something like this: frag-123, and the second alert box will show something like this: container I dont know why. I just want to get the ID value of a child DIV, not the one from the parent DIV. <script> $(function() { $("div").click(function() { var imgID = this.id; alert(imgID); }); }); </script> Please help.

• Access the next button event android

  - by Sephy

  I don't know if it's very clear, but i'm trying to do something when the "next" (bottom right corner of the keyboard) is pressed, and i can't find its keycode. I have tried to look for "next" or "enter" in the keycodes but nothing really relevant... does anyone know? (actually, i've found the enter keycode to be precise, but it does not do anything)

• Event handling to detect if user clicks a 'Like' button in XFBML page

  - by Simon_Weaver

  I have a Facebook connect app / canvas IFrame app which has a Like control for a fanpage. I'd like to detect when the user clicks the Like button to be able to display additional info (a discount coupon code). I'm using the latest Javascript API but the events that can be handled doesn't seem to include detection of social widget controls. The documentation for the Like Plugin doesn't show any events. However I know its definitely possible because if I have two Like buttons on a page they both instantly update each other if I like or unlike whatever it is.

• How to get right values from Views touch event

  - by Pinker

  I have a problem with implementing touch events on GLSurfaceView. Views size is 1280x696, because of android (tablet) status bar at bottom with soft keys, time etc.., (screen resolution is 1280x800), but OnTouchListener is receiving touch events with coords [646.0,739.0], and thus my gluunproject method fails to return correct values is there any way to return events that respect these boundaries? or how should I recalculate the position?

• swing: event listener support class

  - by Jason S

  Is there any preexisting class that helps support add/remove EventListener operations? (kind of like PropertyChangeSupport) I'm trying to partition my code into a model and view in Java. I have some data that arrives erratically, and would like the model to support some kind of EventListener so that a view can subscribe to changes in the model. The data is numerous + complicated enough that I don't want to have to do the whole fine-grained Javabeans property change support; rather I would just like to allow notification that the model has changed in a coarse way. how can I best do this?

• asp.net vb user control raising an event on the calling page

  - by jvcoach23

  i'm trying to learn about user controls. I created a user control that has a textbox and a button. What i'd like to be able to do is when i click the button in the user control, populate a label in the aspx page. I understand that i could just have a button on the page that uses some properties on the user control to get that information.. but i'd like to know how to do it with the button the user control.. the reason for this is the button is just an example.. a learning tool. if i can get this working, i'd likely be putting thing in the user control that might require this kind of passing information. Anyway.. i've found some c# examples that i tried to get working as vb.. but once started getting into the delegates and events.. well.. it made me turn to this post. anyway.. hopefully someone can lend a hand.

• Performance Overhead of Perf Event Subsystem in Linux Kernel

  - by Bo Xiao

  Performance counters for Linux are a new kernel-based subsystem that provide a framework for all things performance analysis. It covers hardware level (CPU/PMU, Performance Monitoring Unit) features and software features (software counters, tracepoints) as well. Since 2.6.33, the kernel provide 'perf_event_create_kernel_counter' kernel api for developers to create kernel counter to collect system runtime information. What I concern most is the performance impact on overall system when tracepoint/ftrace is enabled. There are no docs I can find about them. I was once told that ftrace was implemented by dynamically patching code, will it slow the system dramatically?
