  • Cross-platform, cross-browser way to play sound using jQuery 1.4?

    - by Erin
    I'm trying to get jQuery to play a sound on element hover/click. (It's like a flash website without flash) I've tried the methods recommended in Cross-platform, cross-browser way to play sound from Javascript?, the jQuery Sound plugin and a couple of other tutorials without any success. I'm assuming this is because they haven't been updated since 2008. Does anyone have any recommendations?

    - by maxima120
    I have a console application which has target .NET 2.0 It is very short but full of unsafe code. I converted it to VS 2010. I run it OK. When I try to change "target framework" in properties to 3.5 or 4.0 it shows message box: TargetFrameworkMoniker: Error parsing application configuration file at line 0. XML document must have a top level element. the target then stays 2.0 anyway... Any thoughts?

  • Selecting all elements

    - by Eelke
    This should be really simple but I'm a javascript/jQuery rookie, so here we go: With the following code I can select a certain element var user = $(".ui-selected .user-name").html(); But if there are multiple elements with the above classes, only the first value gets selected. What I would like to accomplish is a variable with all the elements seperated by a , like: user1,user2,user3 ... etc. Any help would be greatly appreciated, thanks in advance!

  • Event to listen to attribute changes

    - by Luis
    I dont think this is possible but maybe someone knows a way to achieve this. I want to attach an event to an html element to listen to attribute change. So say for instance that I want something to happen when a visibility of a div changes. The reason is that I have no control over the javascript that is switching the visibility, hence the need for an event. Thanks

  • Drupal 6 CCK - Having a textbox appear when 'Other' is selected

    - by espais
    I have a special content-type that I have created, and one of the fields is a radio button list. The last element is named 'Other' and I would like to have a textbox appear and allow the user to enter in a non-defined value. Is this sort of capability provided by any sort of module, or is this something that needs to be coded by hand? (If so, would you mind pointing me in the correct direction?)

  • Where are the clever uses of strict evaluation?

    - by devonrt
    It seems like there are plenty of examples of clever things being done in a lazily-evaluated language that can't be done in an environment with strict evaluation. For example infinite lists in Haskell or replacing every element in a tree with the tree's minimum value in one pass. Are there any examples of clever things being done in a strictly-evaluated language that can't easily be done in a lazily-evaluated language?

  • LinkedList.contains execution speed

    - by Le_Coeur
    Why Methode LinkedList.contains() runs quickly than such implementation: for (String s : list) if (s.equals(element)) return true; return false; I don't see great difference between this to implementations(i consider that search objects aren't nulls), same iterator and equals operation

  • how to set footer image in this video screen?

    - by bala
    hi my problem is how to create footer image in this video screen while playing.... how to create this format. now i am give my description: • 1) Header image, a stretched background image. The location of this external image comes from the application xml; • 2) Footer image, a stretched background image. The location of this external image comes from the application xml; 2.a) the copyright, disclaimer and buy block, this block contains links to popup windows that contain a copyright and or disclaimer. And an option to buy the application for the advertisement less version. The content of this block is fed trough the application XML feed. The color of the text is fed by the application xml plus the popup links and texts itself; • 3) Carousel image, a stretched background image. The location of this external image comes from the application xml; 3.a) the carousel contains objects that can flow from right to left, possibly trough a animation (a soft break of the slide). The first object is centered in the middle of the carousel. This is the first element in the video feed. All the subsequent video object are added to the right of the centered object; 4) Total Video object, this object links to window two with the corresponding video of this object. This object is visually build out of the following sub parts:o 4.a) Thumb object (possible playing video thumb); 4.b) Reflection of the Thumb; 4.c) Textual Explanation of Thumb. 1) Video stream, this is the video stream coming from a external server streamed to the television (maybe up scaled) as 720p stream; 2) Advertisement, the type of advertisement shown overlaid on the video is based on previous settings in the video feed. This could mean that Admob, Adsense or a third party image plus URL could be shown. When the advertisement is selected trough navigation (it will highlight in a different color as a border around the advertisement. The color an thickness can be managed trough the application xml), when clicked a browser will open with the associated site (the application will be pushed to the background process, when the user is finished it will return to the app); 3) A back button, an image and navigational element. The location of the image comes from the application xml. The button is only shown when a cursor is moved (a button is pressed on the remote) it will highlight when selected and when pressed will forward the screen to the main window. When the main window is opened the video will be removed from cache and memory and cannot be start from the point it was exited. please give me your idea....

  • How to add fadeIn and fadeOut to idTabs plugin's JS snippet?

    - by iMagdy
    Hi, I am using the jQuery plugin idTabs [ [www.sunsean.com/idTabs][1] ] and it allows me to line tabs and tabs' content via element#id and element href="#id" Ok, so I use this snippet: <script type="text/javascript"> $(document).ready(function() { $("#requestPool").idTabs(); $(".tabs").idTabs(); $(".miniTabs").idTabs(".active"); $(".switchers").idTabs(".activePanel"); }); </script> To run the plugin on two different areas: div#requestPool this has it's own tabs and it's own tab content, Also the div.tabs which is another place and has it's own tabs and it's own tabs content. The div.miniTabs and div.switchers are the divs that includes the tabs links (tabs headers) and I putted them in the snippet to change the default selected tab class from .selected to .active and .activePanel Now, what I would love to add is a nice fadeIn and fadeOut effects to the content of my tabs while browsing through them. Thanks Here is the HTML code for one of the tabbed areas: <div id="requestPool"> <!-- The tabs heads --> <div class="miniTabs"> <a href="#today" class="active">Today</a> <!-- First active tab --> <a href="#tomorrow">Tomorrow</a> <a href="#friday">Friday</a> <a href="#saturday">Saturday</a> <a href="#sunday">Sunday</a> <a href="#monday">Monday</a> <a href="#tuesday">Tuesday</a> </div> <!-- The tabs contents (the ones that I want them to fade in and out while browsing through them using the tabs above) --> <div id="today"class="miniTab"></div> <div id="tomorrow"class="miniTab"></div> <div id="friday"class="miniTab"></div> <div id="saturday"class="miniTab"></div> <div id="sunday"class="miniTab"></div> ...etc the week days </div> Thanks very much (again the tabs are working very fine, but without the fade effect which I want to have).
