  • jquery: i have to use parseInt() even when deal with numbers, why?

    - by Syom
    i have the following script <select id="select1"> <option value="1">1day</option> <option value="2">2day</option> <option value="3">3day</option> </select> <select id="select2"> <option value="1">1day</option> <option value="2">2day</option> <option value="3">3day</option> </select> and jquery $("#select2").change(function() { var max_value = parseInt($("#select2 :selected").val()); var min_value = parseInt($("#select1 :selected").val()); if(max_value < min_value) { $("#select1").val($(this).val()); } }); and now, what i can't understand anyway - if values of option elements are integer numbers, why i have to use parseInt()? in some cases it doesn't work without parseInt(). Thanks

  • How do you have jquery slide up and down on hover without distorting shape?

    - by anita
    How do you have an object slide up as if it were hidden behind something, rather than bending out. example In the jsfiddle demo, you can see the circle bends flat as it slides, but I'd like it to slide out as if it were hidden behind something. (I unfortunately can't just put an image or div with the same background color over the circle and have the circle underneath slide upward.) html <div class="button">Hover</div> <div class="box"> Sliding down! </div> jquery $('.box').hide(); $('.button').hover( function() { $('.box').slideToggle('slow'); } ); update: You guys had really good answers! But I found one of the solutions: http://jsfiddle.net/7fNbM/36/ I decided to just wrap the .button div and .box div in a container, and give the container a specific height, specific width, and overflow of hidden. This way I wouldn't have to cover the image in the background and it provides the effect I was looking for.

  • jquery-ui drag and drop - how to dropped items?

    - by user246114
    Hi, I'm trying to use jquery-ui. I am using one of the drag and drop examples which is pretty much exactly what I need, except instead of moving items between the two lists, I'd like the items to be cloned: http://jqueryui.com/demos/sortable/#connect-lists $(function() { $("#sortable1, #sortable2").sortable({ connectWith: '.connectedSortable' }).disableSelection(); }); <ul id="sortable1" class="connectedSortable"> <li class="ui-state-default">Item 1</li> <li class="ui-state-default">Item 2</li> <li class="ui-state-default">Item 3</li> </ul> <ul id="sortable2" class="connectedSortable"> <li class="ui-state-default">Item 1</li> <li class="ui-state-default">Item 2</li> <li class="ui-state-default">Item 3</li> </ul> so moving an item from the first list to the second list results in list 1 have 2 items, and list 2 having 4 items. I just want it to make clones of the items on the drop. So in the above example, list 1 would still have 3 items, but list 2 would have 4 items, Thank you

  • jquery help assigning multiple mouse events using a .each() to hide/show icons and show background c

    - by Ronedog
    Need some help assigning a mouseover event to display some icons that start out hidden. For every <li> in the ul, I have icons. When the user mouses over the <li> I want the span tag with a class called "icons" to be displayed. When the mouse out event occurs remove the class and/or just hide the span. The problem for me is how to assign event so just the span tag and its contents appear and disapear when the mouse hovers over the <li>. Heres the HTML: <ul id="nav"> <li>Cat 1 <span class="icons"> <div>stuff here</div> </span> </li> <li>Cat 2 <span class="icons"> <div>stuff here</div> </span> <ul> <li>Sub Cat 2A <span class="icons"> <div>2A stuff here</div> </span> </li> </ul> </li> </ul> Heres my jquery code. $('#nav li').each(function(){ //Add Background Shading o Mouseover to all Rows in the menu $(this).mouseover(function(){ $(this).addClass("background_grey").removeClass("icons"); }) $(this).mouseout(function(){ $(this).removeClass("background_grey").addClass("icons"); }); }); Thanks for the help.

  • Files served from Apache are slower than other methods

    - by Jiraiya-Sama
    Hi I have a vps with a 1Gb/s line, when running apps on the server I can get (be it not full) reasonable speeds, but when downloading files through apache from this server I never reach close to my line speed usually 600kb/s where I know the line should be able to comfortably do 1MB/s and more. What can I do to increase the download speeds. Is there maybe a freeware or opensource php script that will increase my speeds? Note. I have confirmed that my server can upload at more than 1MB/s, also that I can download at 1MB/s or more. Also I want to increase the speeds without a download accelerator. Thanks for any help.

  • Outlook Anywhere inconsistencies with authentication methods

    - by gravyface
    So I've read this question and attempted just about every other workaround I've found online. Problem seems completely illogical to me, anyways: SBS 2011, vanilla install; haven't touched anything in IIS or Exchange outside of what's been done through the checklist (brand new domain, completely new customer) except to import an existing wildcard certificate for *.example.com (which is valid, Remote Web Workplace and Outlook Web Access work fine). On the two test machines and one production machine running a mixture of Windows XP Pro, Windows 7 and Outlook 2003 through to 2010, I've had no problem saving the password after configuring Outlook Anywhere using the wrong authentication method. I repeat, I have had no issues using the wrong authentication method on these test machines; password saves the first time, no problem, can verify it exists in the credentials manager (Start Run control userpasswords2), close Outlook, reboot, go make a sammie, come back, credentials are still saved. When I say wrong, it's because I was choosing NTLM and Exchange (under Exchange Console Server Configuration Client Access) was set by default to use Basic. On two completely different machines setup by a co-worker, they had (under my guidance) used NTLM as well... except that frustratingly, Outlook would always ask for a password. One machine was Windows XP with Outlook 2010, the other was Windows 7 with Outlook 2003. When these two machines were set to use Basic -- the correct settings -- the option to save was there and now works without issue. Puzzled by how my machines could possibly work with the wrong authentication, I then went into one of them and changed the authentication method to Basic. Now here's where it gets a little crazy: if I go under Outlook and change the authentication to use the correct setting (Basic) it fails to save the password and Outlook prompts every time (without a "remember me" checkbox). I have not had a chance to change it to Basic on the other two machines to see if this is just a fluke or not, but something just isn't right here. My two hunches are either a missing/installed KB Update or perhaps a local security policy. I should add that none of the 5 test machines in the equation here have ever been joined to the domain.

  • Suggest methods for testing changes to "pam.d/common-*" files

    - by Jamie
    How do I test the changes to the pam.d configuration files: Do I need to restart the PAM service to test the changes? Should I go through every service listed in the /etc/pam.d/ directory? I'm about to make changes to the pam.d/common-* files in an effort to put an Ubuntu box into an active directory controlled network. I'm just learning what to do, so I'm preparing the configuration in a VM, which I plan to deploy in metal in the coming week. It is a clean install of Ubuntu 10.04 Beta 2 server, so other than SSH daemon, all other services are stock.

  • Reverse Proxy Methods for Hosting a Low-Bandwidth Dynamic Website

    - by Casey
    I am building a webcam w/ HTTP server that will be running from a low-bandwith connection. The content on the site will be changing every 5 to 10 minutes. Instead of serving files directly from this connection, are there hosting companies that can act as a reverse proxy for my site? Therefore, if nobody is using the site, the local internet connection remains idle. And if I receive 1000 hits all at the same time, only one HTTP GET is required, and the hosting company (on a fat pipe) continues serving the other 999 requests? This doesn't sound like a very common usage model, but I feel like this would be the optimal solution to my situation.

  • Alternative Methods of Sharing Folders in Windows?

    - by Blaenk
    Hey guys. I'm running Windows 7 and as of now I simply share folders as one usually does in Windows. I then have a MacBook with Leopard (Now Snow Leopard) which I use to connect to my computer to mount the shares by going to Finder, then CMD + K and typing smb://BlaenkPC (The name of my PC) into the address box. This consequently connects to my computer and mounts all of the shares. The problem is that sometimes, if for example I close my MacBook (Which makes it go to sleep) or sometimes even without doing that, the connection somehow drops. Sometimes I close the MacBook and upon re-opening it, everything still works; it's random. It still shows the computer as being connected, but it just shows 'loading' indefinitely. If I hit 'eject' with the intention of re-connecting to the computer, it disappears from the sidebar (The Computer Icon) in Finder, but I cannot re-connect. Activity Monitor (or ps aux, whichever) both show hung instances of umount; one for each share that was mounted. I cannot kill these processes with kill or killall (Yes, even with sudo, and sending signal -9). This has happened to me before, and here is another person who has experienced this. My question boils down to this: Is there an alternative method of sharing folders in Windows, that my Mac can read/understand, that is possibly more reliable and preferably just as fast? I usually use the mounted shares to watch television episodes off my computer, or movies, etc. (In other words, I open them in VLC and they automatically stream from my computer). As far as I can tell, this is a problem with the Samba protocol. I have heard of NFS, but I am not sure if I would have to re-format my drives, or what. I don't mind running a service or daemon to allow the sharing of the folders, I just want it to be done and hopefully in a better way than typical Windows shares through Samba. Usually when I encounter this problem, which is often (read: every day), I have no other option but to restart the MacBook. As I stated in the first question I linked to, shutting down and restarting don't work; I have to manually force the shutdown by holding the power button. I have not modified my installation of Mac OS X in any hackish way, so I doubt it's something with the Operating System, but worst come to worst, I might end up reformatting and doing a clean install to see if that fixes anything, as I am at a complete loss as to what may be causing the problem, and no one else seems to have any idea or care, despite there being quite a few people suffering from this problem, as my research has shown. Any pieces of information that can help are extremely appreciated. You don't have to answer every question on here, but maybe even some insight as to why it might not be possible to kill those hung umount instances for example, or why I may not be able to reconnect using samba (Is it something regarding the way the protocol works?). One thing to note is that I have another computer in the home network that doesn't seem to have this problem. However, it is also running Windows 7 (Note though that I am not using the homegroup feature, but the typical windows sharing feature). My only deduction is that the problem is being caused by the way the Mac (Or Samba implementation, whichever) is handling things. Perhaps it is a limitation.

  • methods for preventing large scale data scraping from REST api

    - by Simon Kenyon Shepard
    I know the immediate answer to this is going to be there is no 100% reliable method of doing this. But I'd like to create a question that details the different possibilities, the difficulty of implementing them and success rates. I would like to go from simple software ip/request speed analysis to high end sophisticated soft/hardware tools, e.g. neural networks. With a goal of predicting and preventing bogus requests and attempts to scrape the service. Many Thanks.

  • Eclipse on Ubuntu: Rectangles instead of Strings and some Java methods and classes

    - by Claus Hausberger
    after upgrading from Ubuntu 9.04. to 11.04 (new installation), I have weird problems with the Eclipse editor. With the Eclipse PyDev plugin, whenever I typ single quoted strings like 'bla', they appear as rectangles (both the quotes as well as the string). First I thought this was a problem with the PyDev plugin, but it also happens with Java and Scala Plugins. With Java, it happens, for example, when typing System.out.println("bla") and then "out" is shown as rectangles only. Weird is that for about half a second I see "System.out.println" and then the editor changes it to System.[][][].println (not really [] (here I used two brackets), it is shown as rectangles). This is very weird. I've never had this before with any Ubuntu, Java or Eclipse version. Currently, I use: Ubuntu 11.04. Eclipse 3.6 Java 1.6.0_25 The latest plugins for Python (2.1) and Scala (beta 5) where used. Eclipse and Ubuntu Terminal is set to UTF-8. The problem also happens when using KDE instead of Gnome. I doubt is has anything to do with Java as I use the same versions on older Ubuntu installations (10.04, 9.10, etc) at work. It does not happen with Netbeans. But I saw once error dialog message from the Update Manager where there were some rectangles in the error widget. Maybe this is the same problem Any ideas what could be wrong here and how to fix this? Eclipse is unusable but I need this for work and also for Scala and Python (the Eclipse plugins for those are very good now). Claus

  • Can I chain authentication methods in Apache?

    - by jldugger
    I've got an existing SVN system that we're migrating away from SVN AuthUserFile (a flat file format) to LDAP authentication. In so doing, we'd like to establish a transitional phase where both LDAP and AuthUserFile work. Does Apache support fall through authentication mechanisms? I'm reading the documentation and it's still not clear either way.

  • Methods to transfer files from Windows server to linux server

    - by Raze2dust
    Hi, I need to transfer webserver-log-like-files containing periodically from windows production servers in the US to linux servers here in India. The files are ~4 MB in size each and I get about 1 file per minute. I can take about 5 mins lag between the files getting written in windows and them being available in the linux machines. I am a bit confused between the various options here as I am quite inexperienced in such design: I am thinking of writing a service in C#.NET which will periodically archive, compress and send them over to the linux machines. These files are pretty compressible. WinRAR can convert 32 MB of these files into a 1.2 MB archive. So that should solve the network transfer speed issue. But then how exactly do I transfer files to linux? I could mount linux drive on windows server using samba, or should I create an ftp server, or send the file serialized as a POST request. Which one would be good? Also, I have to minimize the load on the windows server. Mount the windows drive on linux instead. I could use the mount command or I could use samba here (What are the pros and cons of these two?). I can then write the compressing and copying part in linux itself. I don't trust the internet connection to be very stable, so there should be a good retry mechanism and failure protection too. What are the potential gotchas in these situations, and other points that I must be worried about? Thanks, Hari

  • Windows 2008 Server Unable to activate with other methods

    - by matt king
    I'm trying to activate windows 2008 server SP2 today since the activation trial is done. I do not have an internet connection with this server so I can not activate online, and with the other servers in this farm I've been able to run the slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx and then it would open up the activate by phone method and we would just activate that way. I say again, I don't have an internet connection so I can not do the online activate. If I do the slui 4 it brings up the activation window but show me other ways to activate is still greyed out. I've disabled the NIC on this Hyper-V server and I still can not get the other way to activate to show up... Anyone have any ideas? This computer is one of my AD servers so.. it being in notification mode kind of sucks. Thanks.

  • Best server sync software/methods [closed]

    - by Meep3D
    I have a test server at home and a test server at the office. I'd like to somehow sync multiple folders in both directions automatically so I can work at home and to also provide an offsite backup. I've tried Live Sync (Microsofts own product) but it chokes on large amounts of files and seems a bit rudimentary. Dropbox is also a bit small and does not adapt to our filesystem setup. I have seen a few online backup services but none seemed geared to multiple computers using the same account. I don't mind paying a monthly fee provided the service is good. Suggestions would be greatfully appreciated!

  • Methods and practices for managing a network that has no internet connection

    - by FaultyJuggler
    Originally asked in Super User but realized this belongs here. Long story short, I am setting up a network with 32 servers of varying specs that will be used for testing and development. We will be using RedHat Linux, we also do not have a router as of yet and were looking into making one of the servers act as our router/DHCP etc. The small cluster will be on an isolated network with no internet. I can use external harddrives and discs to transfer anything from external sources into machines on the network, so this isn't a locked down secure network, it just won't have a direct connection to the outside world. I've worked on such setups before, but always long after they were setup. So I'm reaching out to see what everyone knows as far as how groups have handled initial setup and maintenance of such a situation. What is the best way to get them all configured and up to date? What are the best ways to automate updates, network wide installs, etc. With the only given that I have large multi-terabyte external hard drives that would be used to drop whatever files are needed onto a central server, how do i then distribute those files and install their contents? I've done perl scripting, some teammates have played with puppet, so we aren't completely in the dark, I just wanted to avoid reinventing the wheel since this is a common challenge.

  • Why do Floatbox popups stop other animations when finished closing?

    - by isherwood
    I'm trying to essentially run a callback function when a Floatbox popup is closed via a hyperlink inside the popup. I want the page to scroll to the top and my login box to fade in. I'm using the following code: function showLogin() { jQuery('#header_no_theme_login_popup', parent.document.body).show(); window.parent.window.scrollTo(0,0); window.parent.fb.end(); } This works fine, but if I try to use jQuery fadeIn, the fade effect is truncated when the Floatbox popup finishes closing, leaving it with partial opacity. jQuery scrollTo doesn't seem to want to work at all. Thanks much.

  • Accessing Server-Side Data from Client Script: Using Ajax Web Services, Script References, and jQuery

    Today's websites commonly exchange information between the browser and the web server using Ajax techniques. In a nutshell, the browser executes JavaScript code typically in response to the page loading or some user action. This JavaScript makes an asynchronous HTTP request to the server. The server processes this request and, perhaps, returns data that the browser can then seamlessly integrate into the web page. Typically, the information exchanged between the browser and server is serialized into JSON, an open, text-based serialization format that is both human-readable and platform independent. Adding such targeted, lightweight Ajax capabilities to your ASP.NET website requires two steps: first, you must create some mechanism on the server that accepts requests from client-side script and returns a JSON payload in response; second, you need to write JavaScript in your ASP.NET page to make an HTTP request to this service you created and to work with the returned results. This article series examines a variety of techniques for implementing such scenarios. In Part 1 we used an ASP.NET page and the JavaScriptSerializer class to create a server-side service. This service was called from the browser using the free, open-source jQuery JavaScript library. This article continues our examination of techniques for implementing lightweight Ajax scenarios in an ASP.NET website. Specifically, it examines how to create ASP.NET Ajax Web Services on the server-side and how to use both the ASP.NET Ajax Library and jQuery to consume them from the client-side. Read on to learn more! Read More >

  • Formatting minified jQuery, JavaScript using the Internet Explorer 9 Developer Toolbar

    - by Harish Ranganathan
    Much has been talked about the F12 developer toolbar in IE and the support it provides for web developers.  Starting IE8, the Developer Toolbar is a menu item that helps you view the page source, scripts, profiling and many other details of the rendered page.  It even allows script debugging from within and that makes it a truly powerful web developer tool bar. With IE9, the developer toolbar got even better with the Networking Tab that allows you to inspect the traffic/time taken and drill down into the Request/Response headers and other specifics. The script tab allows you to view the scripts used in the page. One of the challenges of working with JavaScript / jQuery when they are minified, is that, it becomes really hard to read.  Minified JavaScript is a compression technique and also a best practice for delivering faster web pages.  However, when you would like to debug, minified JavaScript files become very hard since they aren't properly formatted.  Take the case of the above sample, which is a basic MVC 3 Web Application.  It uses the minified jQuery and modernizr files. Once we select the above scripts, the script source looks as follows:- But with the “Format JavaScript” option in the Configuration icon, Once you click on the “Format JavaScript”, you can see the formatted JavaScript as per screen below:- This makes the script readable and also easy for debugging.  Cheers !!!

  • Ridiculously easy AJAX with ASP.NET MVC and jQuery

    - by eddraper
    After deciding I wanted to dive full-on into the world of ASP.NET MVC 2, I  began doing some research into what would be the best way to support some of my required AJAX functionality on this platform.  The result of these efforts was a barrage of options – many of which required completely different JScript infrastructure than what I planned to go forward with.  As I’ve been delighted with jQuery so far, I began tossing out all approaches that didn’t natively leverage it… Thus, I planned to resist the temptation to take anymore <script> dependencies whatsoever, unless I thoroughly proved that jQuery could NOT do what I planned to do.   Here’s some code I wish I would’ve found early in my research.  This would’ve saved me quite a bit of time and search engine bandwidth. ;-)   <script type="text/javascript">     $(document).ready(function () {         $('#div_name_here').load('<%=Url.Action("ACTION_NAME_HERE","CONTROLLER_NAME_HERE")%>');         $('#id_of_link_I_want_trigger_the_ajax_call')       .bind('click', function (event) {           $('#div_name_where_I_want_to_have_the_ajax_response_loaded_here').load('<%=Url.Action("ACTION_HERE","CONTROLLER_HERE", )%>');       })     }) </script>
