  • SSL with external static content server

    - by SirMoreno
    I have a .Net web application that for performance issues gets all the static data (CSS, Images, JS) from an external server that is on different location and different hosting company. I want to enable SSL on my site without the users getting a message: "Page contains both secure and insecure elements" Does this means I’ll have to get two SSL Certificates one for each server? If I want the users to continue getting the static content from the external server what other options do I have? Thanks.

  • What's faster to parse lots of data (5Mb): eval or json?

    - by AlfaTeK
    I want to get, via ajax, a collection of data objects and parse them into JS data. Currently I have 2 choices: - Server returns valid javascript code and then I eval it. - Server returns JSON object and then I eval the json object What is the fastest of these in Firefox? (I only care about the "parsing" performance, not server or data transfer)

  • How does a javascript closure work ?

    - by e-satis
    Like the old Albert said : "If you can't explain it to a six-year old, you really don't understand it yourself.”. Well I tried to explain JS closures to a 27 years old friend and completely failed. Can anybody consider than I am 6 and strangely interested in that subject ? EDIT : I have seen the scheme example given in SO, and it did not help.

  • jQuery, Quotes, characters etc are breaking my JSON

    - by nobosh
    I'm using json2.js to create a JSON object which JQUERY posts to the Server. The object looks like: [{"locationID":"16","locationDesc":"XXXX"}, {"locationID":"111","locationDesc":"XXXX"}, {"locationID":"12","locationDesc":"XXXX"}, {"locationID":"11","locationDesc":"XXXX"}] Problem here is that XXXX sometimes contains quotes like "we're'" etc.... How should I handle this? Do you I escape somewhere or encode in some way? Thanks

  • zend_application showing blank page

    - by daniel
    Hi, I'm using Zend_Application to bootstrap my app. class Bootstrap extends Zend_Application_Bootstrap_Bootstrap { public static $frontController = null; public static $registry = null; protected function _initEnvironment() { ini_set('display_errors', true); //date_default_timezone_set('Europe/London'); } protected function _initRegistry() { self::$registry = new Zend_Registry(array(), ArrayObject::ARRAY_AS_PROPS); Zend_Registry::setInstance(self::$registry); } protected function _initConfiguration() { $config = new Zend_Config_Ini( BASE_PATH . '/data/server/settings.ini', APPLICATION_ENV ); self::$registry->configuration = $config; } protected function _initLogging() { $config = self::$registry->configuration; $logger = new Zend_Log(new Zend_Log_Writer_Stream($config->logging->file)); Zend_Registry::set('logger', $logger); } protected function _initFrontController() { self::$frontController = Zend_Controller_Front::getInstance(); self::$frontController->throwExceptions(true); self::$frontController->returnResponse(true); self::$frontController->setControllerDirectory( APPLICATION_PATH .'/controllers' ); self::$frontController->setParam('registry', self::$registry); return self::$frontController; } protected function _initView() { $config = self::$registry->configuration; $view = new Zend_View; $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer($view); Zend_Controller_Action_HelperBroker::addHelper($viewRenderer); Zend_Layout::startMvc( array( 'layoutPath' => APPLICATION_PATH .

Filenames / paths are intact. If I add die() to the bottom of my layout.phtml, I get the page. Something is resetting the headers and sending a blank page. My error reporting is on and I get unrelated errors. What could this be?! Thanks!

  • Cannot render javascript from controller

    - by Ermin
    I want to display a modal window with an error message, when the user has entered something invalid in a form, but render another action if everything is ok. However, when I try to display the modal window with render :js => "jQuery.facebox(#{...})" only the actual javascript called is displayed: try { jQuery.facebox(...) } catch (e) { alert('RJS error:\n\n' + e.toString()); alert('jQuery.facebox(\"<div class=\'error\'>Error</div>\")'); throw e }

  • how to redraw markers without redrawing the map? google maps.

    - by vishwanath
    I currently have a implementation where some markers coming from JSON list is shown, on a particular area, Now I want to filter these marker depending upon some criteria, I have done the filtering part, and got the filtered list. Now to render this markers on the map again, The current implementation loads the js with a key again, also creates the GMap2 object and draws the list of marker on the newly created map, which is really annoying. I want map to be there and only markers to be added and removed from the map. Any help is appreciated

  • jQuery to hide and show divs with an indicator

    - by songdogtech
    Using the jQuery below to toggle the hiding and showing of divs of text: how would I add some sort of indicator - like an up and down arrow as a graphic - to the titles when the divs are either open and closed? What's the best way to do that? Two images? A CSS sprite? And most importantly: how would that be integrated into the JS? I've looked at other jQuery that assigns a random number to each div and then determines which are open and which are closed and toggles one of two images. But I'm using php in a WordPress loop to show a posts, and that gives problems with incrementing in the loop, so there must be an easier way that doesn't require changes in the name of the title div. Thanks.... This JS fires the showing and hiding. Each div can be expanded and collapsed independently. $(document).ready(function() { $('div.demo-show:eq(0)> div').hide(); $('div.demo-show:eq(0)> h3').click(function() { $(this).next().slideToggle('fast'); }); }); This is the HTML it works with: <div class="collapser"> <p class="title">Header-1 </p> <div class="contents">Lorem ipsum</div> <p class="title">Header-2</p> <div class="contents">Lorem ipsum </div> <p class="title">Header-3</p> <div class="contents">Lorem ipsum</div> </div> The CSS is arbitrary: .collapser { margin: 0; padding: 0; width: 500px; } .title { margin: 1px; color: #fff; padding: 3px 10px; cursor: pointer; position: relative; background-color:#c30; } .contents { padding: 5px 10px; background-color:#fafafa; }

  • ASP.NET MVC jQuery: Shoud we be concerned about a lot of jQuery/javascript on a View?

    - by Mark Redman
    We are moving from WebForms to MVC and and using a lot of jQuery. I appears we have a lot of jQuery/JavaScript in our Views, is this common and are there any concerns about security. The obvious step is to refactor into plugins and more generic UserControls etc, but this jQuery would still be "visible" by looking at js files etc. We are validating everything on the server-side anyway but should we be concerned?

  • how to unpack the contents of a javascript file?

    - by altvali
    Hi all! You know how those packed js files look like, right? eval(function(p,a,c,k,e,d){ ... } ('obfuscated-string'.split('|'),0,{})) It just so happens to be that i have to tweak some large legacy code that looks like that and i want to find a way to turn this into a more readable version. If that's not possible, can i at least get rid of the eval?

  • Graceful Degradation with JSON.Parse

    - by Steve
    If a browser doesn't support JSON.parse, would it make sense to include json.js and call parseJSON in lieu? So the code would looks something like: var z; if (JSON.parse) z = JSON.parse(yada); else z = JSON.parseJSON(yada);

  • Custom onsynctopreference for XUL textbox

    - by Alexey Romanov
    I wanted to enable custom shortcuts in my Firefox extension. The idea is that the user just focuses on a textbox, presses key combination, and it's shown in the textbox and saved to a preference. However, I couldn't get it to work. With this XUL <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <?xml-stylesheet href="chrome://mozapps/skin/pref/pref.css" type="text/css"?> <!DOCTYPE window SYSTEM "chrome://nextplease/locale/nextplease.dtd"> <prefwindow id="nextpleaseprefs" title="&options.title;" buttons="accept, cancel" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <prefpane id="nextplease.general" label="&options.general.title;" image="chrome://nextplease/skin/Sound Mixer.png"> <preferences> <preference id="nextkey" name="nextplease.nextkey" type="int"/> </preferences> <vbox flex="1"> <hbox align="center"> <label value="&options.general.nextKey;" /> <textbox id="nextkey" flex="1" editable="false" onkeyup="return nextplease.handleKeySelection(this, event);" preference-editable="true" preference="nextkey" onsynctopreference="alert('syncing'); return nextplease.syncKeySelector(this);"/> </hbox> </vbox> </prefpane> <script type="application/x-javascript" src="chrome://nextplease/content/nextpleaseCommon.js" /> <script type="application/x-javascript" src="chrome://nextplease/content/nextpleaseOptions.js" /> </prefwindow> the event in onkeyup works. But when I click the OK button, I don't see a "syncing" alert. Why isn't onsynctopreference working? Is it impossible to have custom onsynctopreference attribute for a textbox?

  • Unzipping zip archives with JavaScript in Firefox 3.6

    - by August Lilleaas
    I am toying with an application that will demo some Firefox 3.6 specific functionality, most of which are listed here: http://demos.hacks.mozilla.org/openweb/ I want to drag a zip file in the browser, unzip it, and work with the unzipped contents. Are there any existing libraries that can do this? Does FireFox 3.6 in particular have something I can use? Or would I have to roll my own unzipper library? For the record: http://github.com/augustl/js-unzip

  • jquery show hidden div

    - by Fahad
    Firstly, I'm sort of embarrassed asking about this, so many people have already asked this question but even after having gone through so many posts, I'm unable to achieve what I want. Basically, a div, initially hidden, has to be displayed on a button click. I tried hiding the div using display:none and hide() and then displaying it using show(), toggle(), and css("display","block"). Using all sorts of combinations of the above, I was still unable to get the result. Code: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <link href="css/smoothness/jquery-ui-1.9.2.custom.min.css" rel="stylesheet" type="text/css" /> <script src="jQuery/jquery-1.8.3.min.js" type="text/javascript"></script> <script src="jQuery/jquery-ui-1.9.2.custom.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $('#one').hide(); $('#Button1').click(function () { $('#one').toggle(500); }); }); </script> </head> <body> <form id="form1" runat="server"> <div id="one" style="height: 20px;width:200px; background-color: Red; "> </div> <asp:Button ID="Button1" runat="server" Text="Show" /> </form> </body> </html> On button click, the div is shown for a brief second before it disappears again. The same thing happens if I use show() instead of toggle() in the above code. Again the same thing if I set style="display:none" to the div instead of using hide() and then use show() or toggle(). I also tried using $('#one').css("display","block"); but again, the same result. Can anyone please tell me where I'm going wrong. Just started learning jQuery and it is really frustrating when something apparently so simple will not work. Thanks in advance. :)
