  • ASP.NET/JavaScript: How to surround an auto generated JavaScript block with try/catch statement

    - by Rami Shareef
    In the Script documents that asp.net automatically generates how can I surround the whole generated scripts with try/catch statement to avoid 'Microsoft JScript Compilation error' My issue is: i got a DevExpress control (ASPxGridView) that added and set-up in run time, since i activated the grouping functionality in the grid I still get JS error says ';' expected whenever i use (click) on one of grouping/sorting abilities, I activated script Debugging for IE, in the JS code turns out that there is no missing ';' and once i click ignore for the error msg that VS generates every thing works fine, and surly end-user can't see this msg so i figured out if i try/catch the script that may help avoid this error. Thanks in advance

  • Browser for cross-site-script testing (for testing Mozilla Add-On)

    - by Anthony
    I am working on a Firefox extension that will involve ajax calls to domains that would normally fail due to the same-origin policy set by Firefox (and most modern browsers). I was wondering if there is a way to either turn off the same-origin restriction (in about:config, perhaps) or if there was a standard lite-browser that developers turn to for this. I really would like to avoid using any blackhat tools, if possible. Not because I'm against them, I just don't want to add another learning curve to the process. I can use curl in PHP to confirm that the requests work, but I want to get started on writing the js that the addon will actually use, so I need a client that will execute js. I also tried spidermonkey, but since I'm doing the ajax with jquery, it threw a fit at all of the browser-based default variables. So, short version: is there a reliable browser/client for cross site scripting that isn't primarily a hacker app? Or can I just turn off same-domain policy in Firefox?

  • JQuery UI Dialog query dialog DOM

    - by Travis
    The following simply loads a jquery-ui dialog from an external html file. $('#showdialog').click(function(e) { var div = $('<div>loading...</div>'); div.dialog({ modal: true, open: function() { div.load('anotherpage.html'); } }); e.preventDefault(); }); After the DOM loads from the external html file, I'd like to interrogate it with JQuery. For example, supposing anothorpage.html had a bunch of anchors on it, I'd like to wire up click handlers for them when it loads into the dialog. Any ideas?

  • Check to see if file transfer is complete

    - by Cymon
    We have a daily job that processes files delivered from an external source. The process usually runs fine without any issues but every once in a while we have an issue of attempting to process a file that is not completely transferred. The external source SCPs these files from a UNIX server to our Windows server. From there we try to process the files. Is there a way to check to see if a file is still being transferred? Does UNIX put a lock on a file while SCPing it that we could check on the Windows side?

  • Linux - Create ftp account with read/write access to only 1 folder

    - by Gublooo
    Hey guys.... I have never worked on linux and dont plan on working on it either - The only command I probably know is "ls" :) I am hosting my website on Eapps and use their cpanel to setup everything so never worked with linux. Now I have this one time case - where I need to provide access to a contractor to fix the CSS issues on my website. He basically needs FTP (read/write) access to certain folders. At a high level - this is my code structure /home/webadmin/example.com/html/images /css /js /login.php /facebook.php /home/webadmin/example.com/application/library /views /models /controllers /config /bootstrap.php /home/webadmin/example.com/cgi-bin I want the new user to be able to have access to only these folders /home/webadmin/example.com/html/js /home/webadmin/example.com/html/css /home/webadmin/example.com/application/views He should not be able to view even the content of other folders including files like bootstrap.php or login.php etc If any sys admins can help me set this account up - will really appreciate it. Thanks

  • Resources for widget creation

    - by Kenji Crosland
    My rails app is about to go live and I'm trying to figure out how to create a widget based on data on the site. My Javascript is not too hot--limited to the O'reilly head first book on JS. I can read simple Javascript okay but when it comes to writing it I'm a little lost. That said, I hope to roll out a widget, maybe a wordpress plugin too soon after my app is launched. Does anyone know of any rails plugins, javascript templates, tutorials or books that can get me going? I did ask a similar question before here: But my limited knowledge of JS kept me from implementing the suggested answer properly.

  • Ogg/Vorbis: _ov_fopen cannot be found

    - by knight666
    I'm trying to use Ogg/Vorbis with OpenAL to get sound in my game. Right now I'm simply trying to load a .ogg file and read its data, I'm not actually doing anything with it. I first tried using ov_open, however, the documentation said I should really be using ov_fopen on Windows. However, when I try to use that I get the following: 1>AudioManager.obj : error LNK2019: unresolved external symbol _ov_fopen referenced in function "private: static struct SomeGame::SoundData * __cdecl SomeGame::AudioManager::LoadOGG(char *)" (?LoadOGG@AudioManager@SomeGame@@CAPAUSoundData@2@PAD@Z) ...and when I Google "unresolved external symbol _ov_fopen", I get exactly one result. And it's in Japanese. So I tried downloading the ogg and vorbis source and compiling it, and inserting those in the project, but it still gives me the same error. Basically, how do I load in an Ogg/Vorbis file to be used with OpenAL on Windows? Thanks in advance.

  • Queue ExternalInterface calls to Flash Object in UpdatePanel - Needs Improvement?

    - by Laramie
    A Flash (actually Flex) object is created on an ASP.Net page within an Update Panel using a modified version of the embedCallAC_FL_RunContent.js script so it can be written in dynamically. It is re-created with this script with each partial postback to that panel. There are also other Update Panels on the page. With some postbacks (partial and full), External Interface calls such as $get('FlashObj').ExternalInterfaceFunc('arg1', 0, true); are prepared server-side and added to the page using ScriptManager.RegisterStartupScript. They're embedded in a function and stuffed into Sys.Application's load event, for example Sys.Application.add_load(funcContainingExternalInterfaceCalls). The problem is that because the Flash object's state state may change with each partial postback, the Flash (Flex) object and/or External Interface may not be ready or even exist yet in the DOM when the JavaScript - Flash External Interface call is made. It results in an "Object doesn't support this property or method" exception. I have a working strategy to make the ExternalInterface calls immediately if Flash is ready or else queue them until such time that Flash announces its readiness. //Called when the Flash object is initialized and can accept ExternalInterfaceCalls var flashReady = false; //Called by Flash when object is fully initialized function setFlashReady() { flashReady = true; //Make any queued ExternalInterface calls, then dequeue while (extIntQueue.length > 0) (extIntQueue.shift())(); } var extIntQueue = []; function callExternalInterface(flashObjName, funcName, args) { //reference to the wrapped ExternalInterface Call var wrapped = extWrap(flashObjName, funcName, args); //only procede with ExternalInterface call if the global flashReady variable has been set if (flashReady) { wrapped(); } else { //queue the function so when flashReady() is called next, the function is called and the aruments are passed. extIntQueue.push(wrapped); } } //bundle ExtInt call and hold variables in a closure function extWrap(flashObjName, funcName, args) { //put vars in closure return function() { var funcCall = '$get("' + flashObjName + '").' + funcName; eval(funcCall).apply(this, args); } } I set the flashReady var to dirty whenever I update the Update Panel that contains the Flash (Flex) object. ScriptManager.RegisterClientScriptBlock(parentContainer, parentContainer.GetType(), "flashReady", "flashReady = false;", true); I'm pleased that I got it to work, but it feels like a hack. I am still on the learning curve with respect to concepts like closures why "eval()" is apparently evil, so I'm wondering if I'm violating some best practice or if this code should be improved, if so how? Thanks.

  • jPlayer problem in Firefox - also throws error from jQuery?! Not related to OGG support.

    - by wolftron
    I've been working on a small SVG website, http://docroot.ca/ - the SVG part has been working out pretty well. In the current site, jPlayer is called and given an mp3. jPlayer functions properly in Safari, Chrome, and Opera, but not Firefox which throws the following two errors: Error: not well-formed Source File: Line: 1, Column: 191 Source Code: <div xmlns="http://www.w3.org/1999/xhtml"><embed name="jqjp_flash_0" id="jqjp_flash_0" src="js/Jplayer.swf" width="0" height="0" bgcolor="#ffffff" quality="high" FlashVars="id=jPlayerBox&fid=jqjp_flash_0&vol=80" allowScriptAccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" /></ and: Error: uncaught exception: [Exception... "An invalid or illegal string was specified" code: "12" nsresult: "0x8053000c (NS_ERROR_DOM_SYNTAX_ERR)" location: "https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js Line: 122"] I'm not sure why the latter happens at all. The former might have something to do with jPlayer's .swf component. The weird thing is the same code works in http://willshown.com/dw, but not in http://docroot.ca. Any guesses as to what direction to take this problem?

  • Communicate between content script and options page

    - by Gaurang Tandon
    I have seen many questions already and all are about background page to content script. Summary My extension has an options page, and a content script. The content script handles the storage functionality (chrome.storage manipulation). Whenever, a user changes a setting in the options page, I want to send a message to the content script to store the new data. My code: options.js var data = "abcd"; // let data chrome.tabs.query({ active: true, currentWindow: true }, function (tabs) { chrome.tabs.sendMessage(tabs[0].id, "storeData:" + data, function(response){ console.log(response); // gives undefined :( }); }); content script js chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) { // not working }); My question: Why isn't the approach not working? Is there any other (better) approach for this procedure.

  • Dynamically loading CSS and JavaScript using Prototype

    - by Salman A
    I have a classic ASP application that I've been constantly trying to modularize. Currently, almost all pages are divided in to two pages: an outer page that contains the layout, header, sidebar, footer an inner page that contains ASP code The outer pages use dreamweaver templates so updating layout and replicating changes is easy. The inner pages are managed by me. Now here is the problem: I had to add a lightbox to one page, I chose Lightbox 2 which requires Prototype. I ended up adding Prototype on every page, assuming that sooner or later I'll upgrade all pages, forms, ajax requests and other javascript to use Prototype. I've now added two other plugins -- Modalbox and Protofade; each with a pair of .JS and .CSS files. Since I'll be using these three plugins on specific set of pages I am wondering if I can load the required CSS and JS files dynamically. I do not want to access the document head and add include files there, I'll have to do this from inside a DIV where all ASP code is supposed to go.

  • ASP.NET 4.5 Bundling in Debug Mode - Stale Resources

    - by RPM1984
    Is there any way we can make the ASP.NET 4.5 Bundling functionality generate GUID's as part of the querystring when running in debug mode (e.g bundling turned OFF). The problem is when developing locally, the scripts/CSS files are generated like this: <script type="text/javascript" src="/Content/Scripts/myscript.js" /> So if i change that file, i need to do a hard-refresh (sometimes a few times) to get the file to be picked up by the browser - annoying. Is there any way we can make it render out like this: <script type="text/javascript" src="/Content/Scripts/myscript.js?v=x" /> Where x is a GUID (e.g always unique). Ideas? I'm on ASP.NET MVC 4.

  • Cannot select/edit TineMCE-generated table

    - by Rakward
    I'm currently using TinyMCE edit in my drupal-website, problem is that beneath the editor, some of the table is sticking out. If I remove the height set by javascript with firebug, it looks fine, even after resizing. So I want to remove the height with JS, I've put this function at the end of my page: $('table#edit-body_tbl').removeAttr('style'); However nothing happens. I test the function in firebug's console, it works perfectly. Basically, the problem is the JS works, but it wont do anything if I simply load it at the end of the page, even in the document.ready function. The TineMCE script is loaded before my script so I should be able to select/edit/delete elements generated by it no? Does anybody know why or how I can force the page to really load my function in the end(currently it is right in front of the -tag)? Other functions in the script work, except this thing ...

  • How do I load content with ujs, jquery and rails?

    - by Joseph Silvashy
    I'm trying to figure out the best way to insert content into a light box using rails UJS. I have a link that looks like this: <%= link_to "login", login_path, :remote => true %> Which produces html as such: <a data-remote="true" href="/login">login</a> So this all works great, and I've created the view file: user_sessions/new.js.erb which also loads just fine, but my question what is the preferred method of inserting appending the html into the page? Like I already have the login form on the non-js page, so can't I just load that partial into the page? Any ideas would be very welcomed.

  • I have lots of images on a html page - how can i make certain ones load first (or certain ones load

    - by imlostmike
    Hi, i have a page with the main content area being big thumbnails, but elsewhere on the page are about 100-200 other (smaller) thumbs that are not important but must still show. What ways do i have to make the main ones show first (or the unimportant ones show last)? I was thinking of these ways: JS load: on page load (once it has finished loading), use a jquery's append() (or whatever other way) to write the html with the image code Set all unimportant images inside a div with style="display:none;". Then once the page has loaded, use JS to set it as visible what do you think is the best way?

  • where to get a wordpress theme review

    - by Ayrton
    Hi I'm currently developing some Wordpress templates and I wanted to get a review by a (semi)professional. I already know quite a bit about Wordpress,CSS, & JS but I was always a lone wolf without any guidance that's why I was wondering where I could find someone (trustworthy) to do something like this and how much he should charge me. It's pure about the code (the PHP, JS & the CSS) I would like to have a review on about (nothing design related). A link to the Wordpress theme I'm talking about: http://demo.wpmonk.com/flowhub Yours truthfully ps: I know you can't give a review on the php on the clientside (however I could mail the source)

  • are there any negative implications of sourcing a javascript file that does not actually exist?

    - by dreftymac
    If you do script src="/path/to/nonexistent/file.js" in an HTML file and call that in a browser, and there are no dependencies or resources anywhere else in the HTML file that expect the file or code therein to actually exist, is there anything inherently bad-practice about doing this? Yes, it is an odd question. The rationale is the developer is dealing with a CMS that allows custom (self-contained) javascript files to be provided in certain circumstances. The problem is the CMS is not very flexible when it comes to creating conditional includes for javascript. Therefore it is easier to just make references to the self-contained js files regardless of whether they are actually at the specified path. Since no errors are displayed to the user, should this practice be considered a viable option?

  • postgres store with composite value type, or a better way of attributing an inverted index

    - by Hassan Syed
    can't seem to figure out the syntax for populating a hstore with a value of composite type -- note: I do not want to convert a record to a hstore. select hstore('hello => ROW(1,2)'); I know it's something simple; However, google is not my friend today. use case : custom inverted index. The data is modelling an inverted index of lexemes, the composite data types are various probabilities related to the lexemes which I will use to implement document clustering. Does anyone know a better way of doing this ? I'm open to using an external system if it allows attaching attributes to key-posting pairs in the inverted index. I'd use something external if it had solid support for what I am trying to do, I suspect that sticking 3-10k lexemes per tuple and then doing batch processing on them is gonna be nasty as the whole hstore will have to be parsed and converted .

  • Zend + Pop Up's balloons on Server Problem

    - by LookUp Webmaster
    Dear Friends from Stackoverflow, Please help me with a problem that i'm having when uploading my project to the server. I'm using pop up's balloons (http://mckay.cshl.edu/balloons.html) for a project using Zend FW and it works fine on my localhost. (I'm using MAMP on MacOSX) but when I upload the webpage to the server, the text inside the balloons is displayed but the images that form the balloon are not, so somehow the js does not recognize the url to the images (the path it's correct, i've checked several times). The server is an Ubuntu 9.04 virtual machine from rackspace.com, running a LAMP server. I'm using the REWRITE function in Apache, so i guess maybe that's the problem. The rewrite configuration is set up using a .htaccess file with the following content: SetEnv APPLICATION_ENV development Options +FollowSymlinks RewriteEngine ON RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule !.(js|ico|txt|gif|jpg|png|css|html)$ index.php Does anyone knows what the problem might be? Best Regards,

  • ASP.NET Web User Control with Javascript used multiple times on a page - How to make javascript func

    - by Jason Summers
    I think I summed up the question in the title. Here is some further elaboration... I have a web user control that is used in multiple places, sometimes more than once on a given page. The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers. However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on. What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss. All comments greatly appreciated. Jason
