  • Proper way to communicate between divs in jquery?

    - by folder
    This is probably a simple question, and i'm just being dense. I've looked through a few jquery books and nothing has jumped out at me, i'm probably missing something. I'm looking for the 'proper', best practices way to communicate between divs/dom items on a page? For example, I have a page with 5 panels that display when a link is chosen, they hide/show/run some code that changes other pieces on the page. Something like this snippet: <ul> <li><div id="unique_name_1_anchor">Unique div 1</div></li> <li><div id="unique_name_2_anchor">Unique div 2</div></li> <li><div id="unique_name_3_anchor">Unique div 3</div></li> <li><div id="unique_name_4_anchor">Unique div 4</div></li> </ul> ...Somewhere else on the page <div id="unique_name_1_panel">Some panel 1 stuff here</div> <div id="unique_name_2_panel">Some panel2 stuff here<div> <div id="unique_name_3_panel">Some panel3 here</div> <div id="unique_name_4_panel">Some panel4 here</div> The concept being when as user clicks on a unique_name_X_anchor div, some action is performed on the corresponding panel (ie show/hide etc...). What I have been doing now is parsing the id ie ($(this).replace("_anchor","_panel") to get the div id of the other dom element. This just seems clunky and there must be a better/more proper way of doing this. Suggestions? Thanks

    - by user320950
    i want to do this: reads the words in the file one at a time. (Use a string to do this) Counts three things: how many single-character words are in the file, how many short (2 to 5 characters) words are in the file, and how many long (6 or more characters) words are in the file.

  • CSS Relative sized header/footer

    - by superexsl
    Hi I'm not a CSS expert so I might be missing something obvious. I'm trying to set a relative size header and footer (so that on larger monitors, the header and footer are larger than on smaller screens). To do this, I'm using a percentage height. However, this only works if I set the position to absolute. The problem is, setting it to absolute means that it overlaps the main part of the screen (inbetween the header and footer). Setting it to relative doesn't work since it relies on items being inside the header/footer. This is what my header looks like: .header { position:absolute; top:0px; background-color:white; width:100%; height:30%; } the ASPX page simply contains <div class="header"></div> Is there a way to get relatively proportioned header and footers? Thanks

  • Does F# kill C++?

    - by MarkPearl
    Okay, so the title may be a little misleading… but I am currently travelling and so have had very little time and access to resources to do much fsharping – this has meant that I am right now missing my favourite new language. I was interested to see this post on Stack Overflow this evening concerning the performance of the F# language. The person posing the question asked 8 key points about the F# language, namely… How well does it do floating-point? Does it allow vector instructions How friendly is it towards optimizing compilers? How big a memory foot print does it have? Does it allow fine-grained control over memory locality? Does it have capacity for distributed memory processors, for example Cray? What features does it have that may be of interest to computational science where heavy number processing is involved? Are there actual scientific computing implementations that use it? Now, I don’t have much time to look into a decent response and to be honest I don’t know half of the answers to what he is asking, but it was interesting to see what was put up as an answer so far and would be interesting to get other peoples feedback on these questions if they know of anything other than what has been covered in the answer section already.

  • Hosted Kerio Mailserver vs. Hosted Exchange

    - by Dayton Brown
    Hi all, I'm in the beginning stages of migrating from an internal exchange server (2003) to external hosted services. We don't have a huge user base, less than 100, but we need to support BlackBerries, iPhones, Outlook RPC/HTTP, etc. I really like exchange hosted providers (I've used intermedia in the past) but pricing is a bit high. Does anyone have any experience with Kerio? It looks great, but I'd like to hear some unbiased opinions. Or biased if you are really happy working for a particular hosting company ;-)

  • Does the Fast Video Download addon share my data?

    - by Frost Shadow
    I've installed the Fast Video Download version 3.0.8 addon for Firefox to download flash videos, like from youtube. What I'm wondering is, how does the addon download it, and do other people see that i'm downloading the videos? For example, is all the software to download the video already on my computer, or does the addon contact someone else to get the video, or let them know? Can the webpage's administrator see I'm downloading the video?

  • Using document.write in event handler?

    - by StackedCrooked
    I am experimenting with HTML and JavaScript. The following code should print something when entering a keystroke in a textbox: <html> <body> <input type="text" id="commandInput" name="command" size="50" /> <script type="text/javascript"> var commandInput = document.getElementById("commandInput"); commandInput.onkeydown = function (evt) { document.writeln("Test"); }; </script> </body> </html> For some reason the textbox disappears when entering a keystroke, leaving nothing but a white page. Any ideas why this is happening?

  • where to store temporary data in MVC 2.0 project

    - by StuffHappens
    Hello! I'm starting to learn MVC 2.0 and I'm trying to create a site with a quiz: user is asked a question and given several options of answer. If he chooses the right answer he gets some points, if he doesn't, he looses them. I tried to do this the following way public class HomeController : Controller { private ITaskGenerator taskGenerator = new TaskGenerator(); private string correctAnswer; public ActionResult Index() { var task = taskGenerator .GenerateTask(); ViewData["Task"] = task.Task; ViewData["Options"] = task.Options; correctAnswer= task.CorrectAnswer; return View(); } public ActionResult Answer(string id) { if (id == correctAnswer) return View("Correct") return View("Incorrect"); } } But I have a problem: when user answers the cotroller class is recreated and I loose correct answer. So what is the best place to store correct answer? Should I create a static class for this purpose? Thanks for your help!

  • Disassemble Microsoft Visual Studio 2003 compiler output

    - by Carl Norum
    I'm seeing what I think is strange behaviour from object files output by the Microsoft Visual Studio 2003 tools. The file utility tells me: asmfile.obj: 80386 COFF executable not stripped - version 30821 For objects created by the assembler, but for objects coming from C files, I get just: cfile.obj: data Using Microsoft's dumpbin utility and the objdump I got from cygwin, I can disassemble the assembly-built file, but I get no useful results from either utility for the C-built files. I have a couple of questions related to this difference: What is the object file format generated by the MSVC2003 compiler? How can I disassemble that object file? I am particularly interested in getting the disassembly in AT&T syntax - I'm doing a port of a large source base to make it work with GCC, and I would like to use this method as a shortcut for some of the inline assembly routines in the project. Thanks!

  • How to add an existing file to a project in VS2008 Add-in?

    - by miliu
    I'm trying to create an add-in for VS2008 to automate the unit tests. The test classes are located in a different project of the same solution. After the test class file is generated, I want to add it to that project automatically and make it active document. I could easily locate the test project, and I also found that testProject.DTE.ItemOperations.AddExistingItem(fileName) can be used to add an existing item to a project. However, this call always adds the item to the current project, instead of the testProject. I'm sure there must be an easy way to do it, but I couldn't figure it out. Your help is much appreciated.

  • How to get the text of a div which is not a part of any other container in JQuery?

    - by Raja
    This should be real easy. Given below is the HTML. <div id='attachmentContainer'> #Attachment# <span id='spnAttachmentName' class='hidden'>#AttachmentName#</span> <span id='spnAttachmentPath' class='hidden'>#AttachmentPath#</span> </div> I want to get just the #Attachment# and not the other text. When I tried $("#attachmentContainer").text() it gives out all #Attachment#, #AttachmentName# as well as #AttachmentPath#. I know I could just put #Attachment# into another span and access it directly but I was just intrigued on how to do this. Any help is much appreciated.
