• Client/JS Framework for "Unsaved Data" Protection?

  - by Kevin Dostalek

  Hey all- we have a typical web application that is essentially a data entry application with lots of screens some of which have some degree of complexity. We need to provide that standard capability on making sure if the user forgets to click the "Save" button before navigating away or closing their browser they get a warning and can cancel (but only when there is unsaved or dirty data). I know the basics of what I've got to do-- in fact I'm sure I've done it all before over the years (tie in to onbeforeunload, track the "dirty" state of the page, etc...) but before I embark on coding this YET AGAIN, does anyone have some suggestions for libraries already out there (free or otherwise) that will help out? Thanks!

• Ipad, closed environment and threat to privacy

  - by Akshay Bhat

  I had an unusual question about ipad, Since ipad environment is closed and does not allows installation of diagnostic and security related programs. How can then we be sure that any of the software installed on ipad is not infringing upon our privacy by doing stuff such as homing back information, etc. We cant install a packet tracer or any other software to check for attacks on privacy. Also given Apples poor track record (the safari browser was broken in one day), I don't think trusting apple solely would be a good idea. This might not seem to be a big issue but for business users it would be a significant concern.

• Is there a certain IIS configuration required to allow a functioning .Net 4.0 ASP.Net MVC 2 Azure ap

  - by erg39

  I just installed the Azure 1.2 tools update and would like to get to work on an Azure project running locally using ASP.Net MVC and .Net 4, but I cannot get MVC pages to load. If I just create a new Azure project in VS 2010, add a ASP.Net MVC web role, and run the application, pages never load. It appears that routing is somehow at fault as controller actions never get called, but if I add other pages to the project (like .htm or .aspx) they will load in the browser. It all works fine with a new project using .Net 3.5, MVC 2 project in the Azure development environment; it all works fine with .Net 4.0 MVC 2 project that is not running in Azure; only the combination does not work. Environment is Win 7 x64 (IIS 7.5), VS 2010, Azure tools 1.2 Is there some magic IIS setting I need to change or something? Any ideas?

• What's the best self-tracking software for Linux?

  - by trench

  I'm looking for a way to track myself and receive quality data upon which I can write future scripts/programs. For example, I use Google Reader a lot. I'd like to track the hrefs that garner my clicks. Further, I'd like to drop all of the words of each href into a database where they can be stacked in a hierarchical manner. At the end of the week I want to know that "Ubuntu" garnered 448 clicks and "Cheetos" garnered 2. :) That's just one example... I'd like this tracking and data-collecting to extend beyond my browser. I know writing something to do this myself wouldn't be too awfully difficult but if something already exists I'd happily use it. Thanks in advance. Primary OS: Ubuntu 10.04

• Javascript performance issue

  - by Daniel

  Hello, I've built a top menu based on superfish, but the amount of displayed items in the menu is huge. And there is also alot of jquery on the top menu. Now to the problem, everytime I load any page that has the menu, the browser(ie7) feels like it looks it locks it self for about 1-2 seconds while the page is being loaded. I'm sure that the top menu is the issue, and I would like to improve the performance of the page.(besides removing the menu and removing the menu items) I've used firebug to see which calls take most of the times, and I the calls are standard jquery or superfish. The top menu is a ascx control. Are they any good ways to let the page load first and the menu later or any other goods ideas to improve the performance?

• How to fetch message body and attachments in XML format using php/linux from Lotus Domino server?

  - by too

  Has anybody some information about accessing Lotus Domino server to fetch entire mail contents by http(s) requests from php linux server? The article by Andrei Kouvchinnikov describes well how to fetch message list in notes mail folders; after obtaining session id during login one can for example select top 100 messages by calling: https://your.server.domain/mail_db/mailbox.nsf/($Inbox)?ReadViewEntries&Start=1&Count=100 And this works perfectly. The problem arises when I am trying to get message contents (0A1DA5EEB7B65277C12576F50055D811 is an example message unique Id): https://your.server.domain/mail_db/mailbox.nsf/($Inbox)/0A1DA5EEB7B65277C12576F50055D811/?OpenDocument Such request in IE shows frameset with data hard to parse, in less common browsers like Opera it informs about unsupported browser. Ideally if it is possible to fetch notes message contents and all attachments by requesting it in the url, has anybody some information what request would it be? Link to Lotus web calls reference would be even more beneficial.

• How can I embed firefox in a GUI application?

  - by PeniWize

  Has anyone ever embedded the firefox web browser technology in their own [unmanaged] C/C++ GUI application in the same way that IE can be embedded as a COM object? (I would like to do this on Linux, not Windows). Are there "better" alternatives to firefox? I'm open to anything as long as I can use it with non-GPL code. My needs are fairly basic; I only need fundamental HTML parsing and display of static local files, but I'd take advantage of more sophisticated technology, if I can get it. I'd like to be able to use JavaScript, but I can get by without it.

• Unable to set relative path for flash file in ASP.NET MVC using AC_FL_RunContent

  - by Mahesh

  Hi, I have a website using asp.net mvc in which I need to embed a flash file in view. I am unable to set the relative path for the flash file. Given below is the code I am using: AC_FL_RunContent( 'codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0', 'width', '487', 'height', '359', 'menu', 'false', 'movie', 'images/butterfly', 'quality', 'high', 'allowscriptaccess', 'sameDomain', 'pluginspage', 'http://www.macromedia.com/go/getflashplayer' ); where I copied butterfly.swf in a directory called images. images directory resides in the views folder. If I use code behind( default.aspx default.aspx.cs) in a different solution with the same folder strucuture, browser is able to load the flash file. Could you please throw some light on the MVC folder structure issue?? Thanks a lot. Mahesh

• jquery checked checkbox IE problem

  - by lidermin

  Hi, I'm having an issue verifying if a checkbox is checked using jquery on Internet Explorer. This is the code I'm using: if ($('#chkjq_1').attr('checked') == true) It works fine on Firefox or Chrome, but on Internet Explorer 7, the condition is always false because the browser sets the property this way: <input id="chkjq_1" type="checkbox" CHECKED/> IE7 And the right way is the following: (Firefox, Chrome): <input id="chkjq_1" type="checkbox" checked="checked"/> FF, Chrome, etc What should I do to avoid this issue on Internet Explorer 7; is there a generic way in jquery to solve this? Thanks in advance.

• firefox: getting access to the list of tabs/windows to restore on startup

  - by robb

  Sometimes ffox fails to restore the previously open tabs/windows. This might be happening when some of the urls to be opened are no longer reachable (e.g. behind a vpn) or after the underlying OS (Windows) has been forcibly restarted (e.g. to complete an automated patch installation). Anyway, after restarting, can this list of urls be recovered somehow? Say for example, I was daft enough to have clicked on "start new session". Can I still get access to the old list of open urls? There is the browser history of course, but it contains a lot of stuff - the urls that were open when ffox last exited are not obvious. It would be neat if they were marked in some way - tagged for example. .robb

• Web Service in c# - "This web service is using http://tempuri.org/ as its default namespace."

  - by glenatron

  I've created a web service using Visual Studio ( 2005 - I know I'm old school ) and it all compiles fine but when it opens I get warned thus: This web service does not conform to WS-I Basic Profile v1.1. And furthermore: This web service is using http://tempuri.org/ as its default namespace. Which would be fine except my service begins thus: [WebService(Namespace = "http://totally-not-default-uri.com/servicename")] Searching the entire solution folder for "tempuri" returns nothing. I can't find it mentioned in any configuration page acessible from Visual Studio. And yet it's right there in the wsdl:definitions list for the xmlns:tns attribute on the web service descriptor page when I view it through the browser and as targetNamespace in the same tag. I'm viewing it using Visual Studio's "debug" mode with the built in server from that. Seems like something has got cached somewhere but I can't work out what and where- I've tried stopping and restarting the server, cleaning and rebuilding the service and going through the associated text config files with a text editor but no dice. Any idea what is going on?

• IE 8 Caching Problem

  - by Jeff Catania

  One of my javascript sources had an extra comma that was throwing an error in IE8. So I opened up my editor, deleted the comma, and saved. I reloaded IE8, but it was still pulling the old js file. I deleted everything in "Delete Browsing History...", and restarted the browser. It is still pulling the old file. I even set up a log on my server to show whenever the js file was requested. When reloading with IE, the js file is never requested. I tried doing the same process in Chrome and FF, and it pulled the new file and logged properly on the server. Is there some other cache that I am failing to clear in IE that would cause this problem?

• Development deployment: how to achive edit-and-reload with JSP pages?

  - by doublep

  Out project uses WebLogic as web-server and uses mostly JSP for user interface. With standard setup it is possible to copy edited JSP files into the exploded deployment directory and WebLogic will automatically pick them up, recompile and serve new content through HTTP. However, is it possible to avoid copying at all, so that I just save a file in my editor and it is immediately (well, after a couple of seconds for recompilation) visible? The project uses Apache Ant as building tool. I would imagine what I want would be possible with symlinks (since this is for deployment only I don't care about cross-platformity), but then I don't see how it is possible to symlink lots of files at once with Ant. So, how do I achieve save-JSP-hit-F5-in-browser functionality either with some setting in WebLogic; or with symlinking JSPs using Apache Ant (instead of copying them as is done now); or something else completely?

• Blinking an item. (Jquery FadeIn FadeOut ?)

  - by 0plus1

  I have two divs that I want to make blink at the same time until the user hovers the mouse on one of them. var shouldiblink = '1'; function mrBlinko(divid){ while (shouldiblink =='1') { $("#"+divid).fadeIn(100).fadeOut(300); } $(document).ready(function(){ mrBlinko("mydiv1"); mrBlinko("mydiv2"); } The I'll have an hover event that sets shouldiblink to '0'. Problem is that the loops starts as soon as the page is ready and the browser crashes. I'm stuck with this solution and I can't think of an alternative right now. Can you help me? Thank you very much.

• Spring - MVC - Sanitize URL before redisplaying to the user

  - by Raghav

  In my application , a HTTP GET request URL to the application with script tag is getting redisplayed as it is although it fails the authorization. Example: http://www.example.com/welcome<script>alert("hi")</script> The issue is sanitizing external input entered directly into address bar by modifying existing GET URL. Spring redisplays the submitted URL as it is. Though the script does not get executed in the browser(FF), is there anyway to strip the URL of these values before displaying it back to the user Reference: Spring MVC application filtering HTML in URL - Is this a security issue?

• Modify url for bookmarking using JavaScript

  - by jamesaharvey

  I'm exploring my options for modifying urls in the browser bar for bookmarking purposes. Ideally, I'd like to add querystring parameters and cannot determine if this is even possible. I don't want the page to refresh and want to add querystring values on link clicks, ajax calls, etc. If I can't add querystring parameters, then I'd like to add hash values (http:://someurl.com#hash-value). How should I go about doing this? Should I use plain JavaScript or a framework (jquery, prototype, etc.) and/or framework plugin.

• Dynamic notifications using jQuery

  - by sparkymark75

  I'm currently building a homepage for our staff which is to be set as the homepage in their browser. I'm currently building the facility whereby nominated members of staff can send notifications to all staff. These will popup on their home page without the need for them to refresh the page. I've currently got the code below which worked fine for 1 notification, but there may be more than 1 at a time waiting to be shown. I've switched to outputting json but I'm not sure how to modify my code to consume it. I'm using the PeriodicalUpdater and jGrowl plugins to get this functionality, if there's better alternatives then feel free to sugget them. $.PeriodicalUpdater({ url: 'getNotifications.aspx', maxTimeout: 6000, type: 'json' }, function(data) { var message = data; if (message != '') { $.jGrowl(message, { sticky: true }); } }); As an additional piece of functionality, would it be possible to store in a cookie when a user has closed a notification so they don't see it again? Thanks.

• Javascript timer in parent window is cancelled on child window close

  - by Tom Carter

  I have a user UserControl on a web page. There is a javascript timer started by the control on the client that causes a web service to be called every few seconds. If the user clicks on the control a new browser window is opened (with window.open() ) to show a different page. Note the onclick returns false so there is no postback to the page. The page displayed in the second window also has a timer that operates in the same way as the first (calls a WebService at intervals). Upto this point everything is fine - each of the timers continue to run in their respective window. However, when I close the second window (either by clicking on the cross of the window or by calling self.close() ) the timer in the first stops. I've no idea why. Is there some relationship between the opener and opened window that I'm missing ?

• small javascript problem

  - by dfg

  Hi, I have this little function that opens modal window type thing. The problem is that it doesnt work on IE. All other browser its fine, but on IE, nothing happends: function showOverlayBox() { if( isOpen == false ) return; $('#full').css({ display:'block', left: ( $(window).width() - $('#full').width() )/2, top: ( $(window).height() - $('#full').height() )/2, position:'absolute' }); $('.BgCover').css({ display:'block', width: $(window).width(), height: $(window).height() }); } function doOverlayOpen() { isOpen = true; showOverlayBox(); $('.BgCover').css({opacity:0}).animate( {opacity:0.8} ); return false; } function doOverlayClose() { $('#full').css( 'display', 'none' ); $('.BgCover').animate( {opacity:0}, null, null, function() { $(this).hide(); } ); } Maybe something to do with isOpen == false?

• Changing content of HTMLDocument displayed in a JTextPane

  - by kayahr

  I'm displaying some tables as HTML code (rendered by a Freemarker template) with a JTextPane. I also have some HTML links in this HTML output which can be used to interact with the values of the table (For example "Delete a row" and stuff like this). Currently I always recreate the whole HTML output on each change and replace the whole document in the JTextPane with the new one. This is getting really slow and the JTextPane always changes the scroll position when I do this. Is it possible to change only parts of the HTML code during runtime without replacing the whole document? In a real browser I would use the DOM and do something like document.getElementById("price").innerHTML = "$123.44". Is something like that possible with the HTMLDocument in a JTextPane?

• What web based programming environments exist to learn on?

  - by jjclarkson

  I loved appjet (the programming environment) before it was taken over by Google. What other web based complete programming environments are out there? Which one do you think is best for starting to do real world coding the fastest? I really think coding from your browser will make programming more accessible to the public. Are there any out there that use a vim style, (e.g. jsvi) in combination with free server side hosting? The last time I looked at Bespin it was a little green. Are there others?
