  • Dojo treemodel- adding large number of items

    - by Ashley
    I am trying to add a large number of items (100+) to my tree via ForestStoreModel by calling newItem in a loop. This seems to be quite slow and locks up the browser. Is there any way I can do something similar to grid's beginUpdate & endUpdate? I want to basically 'turn off' my tree, add 100 items in a batch, then 'turn on' my tree. Any ideas? Thanks!

    - by epmspec
    When i use only langRoute and moduleRoute i have not any problems. But when i add pageRoute it is not work properly. I have tried many another ways do it (Regex etc) but none gives the desired result. Can anybody help me? $front = Zend_Controller_Front::getInstance(); $router = $front->getRouter(); //Route_page needs dispatcher and request $dispatcher = $front->getDispatcher(); $request = $front->getRequest(); // Add languag routes $langRoute = new Zend_Controller_Router_Route_Hostname( ':language.domain.com', array( 'language' => 'ru', ), array( 'language' => '^(ru|en)$', ) ); // Add module routes $moduleRoute = new Zend_Controller_Router_Route_Module(array(),$dispatcher,$request); // Add page routes $pageRoute = new Zend_Controller_Router_Route( ':uri\.html', array( 'controller' => 'index', 'module' => 'default', 'action' => 'index', 'uri' => 'index', ), array ('uri' => '[0-9a-z\-]+') ); // Add chain routes $chainedRoute = new Zend_Controller_Router_Route_Chain(); $chainedRoute->chain($pageRoute); $chainedRoute->chain($langRoute)->chain($moduleRoute); $router->addRoute('default', $chainedRoute);

  • Shadowbox + jQuery not working - No errors.

    - by Shelton
    First, apologies. I'm a js newb. I'm attempting to trigger a shadowbox with the load of a specific page - a "pop-up" if you will. Nothing happens and according to firebug, there are no errors to report. I should note that this is wordpress, so I'm using the default jQuery call and also shadowbox rolled into a WP plug-in. Shadowbox does work properly in other areas of the site, as do jQuery functions. noConflict() is used because WP also loads prototype by default, which conflicts with the jQuery dollar sign. var $j = jQuery.noConflict(); $j(function(){ //Set cookie $j.cookie('padpop_viewed',true); // open a welcome message as soon as the window loads $j(function() { Shadowbox.open({ content: '<div width="600" height="460" style="margin:auto;"><a href="<?php bloginfo('url');?>"/products/"><img src="<?php bloginfo('template_url');?>/images/ipad-pop.jpg" width="600" height="460" alt="Redacted"/></a></div>', player: "html", height: "470", width: "610" }); }); }); Any help here would be greatly appreciated as I have spent hours consulting the documentation of each aspect of this. Thanks, S.

  • Code producing System.NullReferenceException error for Membership.GetUser(). This is VB.Net (ASP.Net 4)

    - by Derrek
    I have a Default.aspx page that is not static. I have added functionality with datalist and sqldatasources. When a user logins he/she will see items like saved workouts, saved equipment, total replys, etc... This is based on getting the currently logged in user UserID. Quite simply this works great when the user is logged in. However, I do not want to force a user to login to view the Default page because it does have functionality on it that does not require login. When a user is not logged in of course I receive the [System.NullReferenceException] error. I understand the error well but I do not know how to code to fix it. That is where I need help. I will admit I am more designer than developer. However, I do know the exception error I am receivving is caused by me not setting a value in my code when a user is not logged in. I do not know how to do that and have for a week made unsuccessful attempts at writing the code. Both sets of code below compile for VB.Net/ASP.Net 4/Visual Studio 2010 without errors. However, I still get the System.NullReferenceException error if not logged in. I know it can be done but I do not know the right syntax. If you can help please insert you code in mine or write it out. JUST TELLING ME WHERE TO GO TO FIND AN ANSWER WON'T HELP. I HAVE DONE THAT FOR 7 STRAIGHT DAYS. I APPRECIATE OUR HELP.

  • Gmail HTML5 Feature to "drop" attachments

    - by Pablo Fernandez
    I've seen this and I have to admit I'm pretty impressed: http://bit.ly/bkU9r5 I'm almost certain that this is an HTML 5 feature (it's supported on Chrome and Firefox 3.5), and was wondering if somebody knew how is the browser feature called. Bonus points for a tutorial/article on how to do something similar!

  • Onclick not added until after Postback

    - by Morph
    I have the following: <asp:Button id="SubmitButton" Text="Submit" runat="server" OnClientClick="Do();" OnClick="SubmitButton_Click"/> When the page is first rendered, I go to the view source in my browser and see that the onclick="Do();" is not added to my submit button tag. But when I do a post back, and do the view source again, the onclick is added to the submit. Why would the onclick not be there on the first request?

  • Comparing lists of field-hashes with equivalent AR-objects.

    - by Tim Snowhite
    I have a list of hashes, as such: incoming_links = [ {:title => 'blah1', :url => "http://blah.com/post/1"}, {:title => 'blah2', :url => "http://blah.com/post/2"}, {:title => 'blah3', :url => "http://blah.com/post/3"}] And an ActiveRecord model which has fields in the database with some matching rows, say: Link.all => [<Link#2 @title='blah2' @url='...post/2'>, <Link#3 @title='blah3' @url='...post/3'>, <Link#4 @title='blah4' @url='...post/4'>] I'd like to do set operations on Link.all with incoming_links so that I can figure out that <Link#4 ...> is not in the set of incoming_links, and {:title => 'blah1', :url =>'http://blah.com/post/1'} is not in the Link.all set, like so: #pseudocode #incoming_links = as above links = Link.all expired_links = links - incoming_links missing_links = incoming_links - links expired_links.destroy missing_links.each{|link| Link.create(link)} One route I've tried: I'd rather not rewrite Array#- and such, and I'm okay with converting incoming_links to a set of unsaved Link objects; so I've tried overwriting hash eql? and so on in Link so that it ignored the id equality that AR::Base provides by default. But this is the only place this sort of equality should be considered in the application - in other places the Link#id default identity is required. Is there some way I could subclass Link and apply the hash, eql?, etc overwriting there? The other route I've tried is to pull out the attributes hash for each Link and doing a .slice('id',...etc) to prune the hashes down. But this requires writing seperate methods for keeping track of the Link objects while doing set operations on the hashes, or writing seperate Collection classes to wrap the incoming_links hash-list and Link-list which seems a bit overkill. What is the best way to design this interaction? Extra credit for cleanliness.

  • Is external JavaScript source available to scripting context inside HTML page?

    - by John K
    When an external JavaScript file is referenced, <script type="text/javascript" src="js/jquery-1.4.4.min.js"></script> is the JavaScript source (lines of code before interpretation) available from the DOM or window context in the current HTML page? I mean by using only standard JavaScript without any installed components or tools. I know tools like Firebug trace into external source but it's installed on the platform and likely has special ability outside the context of the browser sandbox.

  • Is it worth learning C# or Java in 2010

    - by Dhawal
    We are in web era standalone applications are almost gone everyone wants their internet application to run inside browser, programming languages like Ruby, Python and scala are becoming more and more mainstream. Sometimes I wonder what these programming language offer which make them top choice of IT companies, if I plan to become a freelance web developer is it worth learning C# or Java. I read beginner's book for both of them, but to master any of them require some time investment.

  • Why aren't Admob click callback delegate methods not getting called?

    - by executor21
    I'm integrating the latest version of the admob sdk (version 20100412) into my app. The ads get displayed, but I need the app to make some changes when an ad is clicked and admob displays a full-screen browser. However, none of the callback methods (willPresentFullScreenModal, didPresentFullScreenModal, willDismissFullScreenModal, and didDismissFullScreenModal) are called, even though other delegate methods are. Why aren't these callbacks being made? They were in the previous versions of the SDK, and the sample app doesn't use them, so it's no help.

  • Get image data in Javascript?

    - by detariael
    I have a regular HTML page with some images (just regular IMG HTML tags). I'd like to get their content, base64 encoded preferably, without the need to redownload the image (ie. it's already loaded by the browser, so now I want the content). I'd love to achieve that with Greasemonkey and Firefox.
