• Fastest tr:hover method

  - by Alex

  What is the single fastest method for table row hover css change? I've tried jQuery (onmouseover/out) and CSS with tr:hover, but once I make my page fullscreen (1920x1200) the performance on my grid is getting just sluggish enough to give the entire page a feel of being sub-par. That's on a grid with 25 rows, and some spans and divs per row. I've tried IE and Google Chrome. Is there another, faster method? What is generally considered the fastest method across browsers for doing hover CSS changes?

• How to enable/create elements on the fly

  - by Simon S

  Hi all I am using a combination of PHP, jQuery and Spry to serve a series of listboxes in which a user will select first the type of vehicle, then the make, then the model and finally the specific model. All my listboxes (SELECT) are working fine, and they update properly using the Spry elements. Each listbox is populated from a different Spry XML Dataset, and this is my problem. If I present all four listboxes to the user, the script has to go and fetch all four lots of XML to populate all four listboxes, taking several seconds. What I want to do is to create/enable the listboxes in order, so at the user selects from the first listbox, the second is created/enabled, when they select from the second, the third is created/enabled... and so on. Setting the disabled attribute is no good because the script has already fetched the XML before this is processed. Any ideas?? Si

• Bootstrap Modal & rails remote

  - by Kevin Brown

  Using this bootstrap modal extension and animate.css for fun, how can I take a make an easy ajax modal using :remote => true to fill in the modal box? Also, how would I use the bootstrap modal default "submit/cancel" buttons to interact with a form that's loaded? I'm looking for a more dynamic solution instead of hard-html-ing every modal into the page or using a bunch of jquery ajax calls for each dialog. I've done a few quick searches, but they've turned up nil for this particular solution.

• Where would I use a bitwise operator in JavaScript?

  - by J-P

  I've read this (http://stackoverflow.com/quest...), so I know what bitwise operators are but I'm still not clear on how one might use them... Can anyone offer any real-world examples of where a bitwise operator would be useful in JavaScript? Thanks. Edit: Just digging into the jQuery source I've found a couple of places where bitwise operators are used, for example: (only the & operator) // Line 2756: event.which = (event.button & 1 ? 1 : ( event.button & 2 ? 3 : ( event.button & 4 ? 2 : 0 ) )); // Line 2101 var ret = a.compareDocumentPosition(b) & 4 ? -1 : a === b ? 0 : 1;

• Simple ASP.NET MVC Routing question

  - by Robert

  Hi there, I have two pages in my simple MVC App with two defined routes: routes.MapRoute( "Results", // Route name "Results/{id}", // URL with parameters new { controller = "Results", action = "Index", id = "" } // Parameter defaults ); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Main", action = "Index", id = UrlParameter.Optional } // Parameter defaults ); I needed to have the results page load with just a product ID such as this: [MyDomain....]/Results/12345. But also the main page does a POST (using JQuery) to the Results Controller for updates using this route: [MyDomain....]/Main/Update along with a data bag. This works fine when I only have the "Default" route. But when I added the other "Results" route, all the POST calls to update are failing. Any ideas what I'm doing wrong??? Thanks a lot.

• network error 414 when using google translate with wordpress

  - by zac

  I am using a jQuery and google translate on a wordpress site. It works well unless I call a div that is repeated in the loop like in an archives page. On these pages I get a network error 414 that the request URI is too large. The archives page I have are short and the php is only generating about 5 paragraphs for each category archive. Does anyone know how I can correct this error? Is this a serverfault question?

• Can a Javascript bookmarklet overlay an image on a web page?

  - by songdogtech

  Can a bookmarklet be used to overlay an image on a web page? Not as a pop-up, but as a image positioned by CSS and with a high z-index to display on top of other elements. And without a mask i.e., Shadowbox or similar jQuery effect. Just an image from a URL and positioned in the bottom left hand corner of the browser window. This is what I have so far, but it may be the wrong direction to be going: javascript:(function(){document.write("body {background-image:url(http://mydomain.com/image.png); position: absolute; left:50px; top:300px; z-index:9999;}");})() I have a JS function that works as a bookmarklet to change the case of text on the page, and now I'd like to be able to show an image when the bookmarklet is used.

• What is the easiest way to send a Javascript array via JSON to PHP?

  - by dscher

  I have a few arrays that I want to send to process with PHP. Using json2.js I will stringify the arrays like so: var JSONlinks = JSON.stringify(link_array); var JSONnotes = JSON.stringify(note_array); but then I'm confused. Do I need to use a XMLHttpRequest object? Is there another way? If that is the simplest way, could someone please just share the most basic instance of the code needed in order to send to PHP where I can then use JSON decode? I think it might help others in the future really. I'm currently using Jquery and I know there are many options out there for frameworks and each one may or may not make this process any easier. If you're using a framework in your reply please mention why you'd choose that framework rather than just javascript.

• update element in knockout template which was changed by 3td party library

  - by yakov

  I have 'div' element (recaptchaDiv) in knockout template which is not bound to any observable field: <div id="recaptchaDiv"></div> On the other hand, I update this 'div' by 3rd party library. In particular, this is google recaptcha. This is my code: Recaptcha.create("[my private key]", "recaptchaDiv", { theme: "clean", callback: Recaptcha.ToTest }); And it doesn't work (I see nothing). What I know: trying on FF console: $("#recaptchaDiv").html() - it shows the expected html code, I just can't see it in the browser What I tried: to move recaptchaDiv outside of the template and it works: I can see the captcha in the browser to bind recaptchaDiv on html property: in the template: <div id="recaptchaDiv" data-bind="html: recaptcha"></div> in the model: Recaptcha.create("[my private key]", "recaptchaDiv", { theme: "clean", callback: Recaptcha.ToTest }); recaptcha($("#recaptchaDiv").html()); and it doesn't work (replacing jquery on document.getElementById doesn't help) Any help will be very much appreciated!!! Thank you in advance.

• Ajax DragPanelExtender drag an item from one panel to another

  - by Morgeh

  I have a panel called "ItemPot" and several panels called "ItemBank1", "ItemBank2" etc. Currently I have dynamically added 5 items to the pot and given each one a DragPanelExtender so that those items can be moved around within the panel, however what I wan't to be able to do is to move those items into the banks and then save there new parent ID ("itembank1") to the database using C#. Does anyone know of an easy way of doing that? I have looked around the internet and I have found loads of ways of doing similar things using JQuery or Mootools but I would rather not have to use Javascript if possible, I know that might be wishful thinking lol.

• JavaScript helper libraries? No DOM or AJAX stuff

  - by Melmacian

  As I'm writing JavaScript I'm always missing some fairly basic language features that JavaScript just don't have. So is there any library that would bring such features as trim, sprintf, str.endwith and etc. functions to JavaScript ? I just have written those functions too many times and I'm also tired of copy/pasting them from my old code. It would be nice to have some library which has those implemented and tested in one place. Note that I'm not talking about Ajax/DOM-libraries like jQuery or Dojo and such. I know that those libraries bring some of the features that I'm talking here, but not all. And I would like to have also an environment independent library so that same library could be used with server side JavaScript . Best library so far that I've found is php.js, but I don't like how it is polluting the global namespace. I'm also not too fond of how PHP-functions are named.

• What is the preferred way of loading browser-specific CSS files?

  - by Yuval A

  What is the best way to handle browser-specific CSS file loading? Assume you are running in the context of a proper MVC framework. Here are some options, you are free to discuss the pros and cons of these options as well as any other methods you know of, and prefer: Server-side solution: use the controller (e.g. servlet) to analyze the user-agent header in the request and return the proper CSS file in the view. Use browser specific hacks to load files, such as: <!--[if IE]> ... <![endif]--> Load CSS files asynchronously in client side by inspecting user-agent and adding respective files Use a client side framework to handle browser-specifics (such as jQuery browser-specific css rules)

• Rails + facebox + authlogic - how?

  - by Vitaly

  Hello, on my web site I want to have login/registration form in modal window done using facebox (jQuery plugin). What is better: Create view with one method and template that has form and refer facebox to this view. Create static HTML file in public directory and refer facebox to this static page. What I want to achieve is: Easy verification (like "user name already taken", "password confirmation doesn't match password" and stuff like that). Easy submit and redirect I'm new to Rails, I just know about forms verification in Django, so for Django I would probably choose option 1, but it might be another thing in Ruby.

• Google Translate set default language

  - by tdurham

  Maybe this has an obvious solution that I'm overlooking, but I can't seem to find the correct parameter to put in to make this happen. Using the Google Translate widget on a site, I need to set the default language that the user sees when entering the site, even though the site is english. function googleTranslateElementInit() { new google.translate.TranslateElement({ pageLanguage: 'en' }, 'google_translate_element'); } I've tried adding: defaultLanguage: 'fr' and tried: targetLanguage: 'fr' I did find some nice jQuery solutions, but didn't want to bypass this if it was an easy fix. Thanks in advance.

• problem with drupal view and php code

  - by czuroski

  Hello, I have a view set up in drupal and I am using some jquery code within the view which hides some data based upon a text box value. Everything is working fine for me when I am logged in. When I log out and access the block anonymously, it doesn't work correctly. I am somewhat new to drupal, and don't know where to begin troubleshooting. I assume it is a permissions issue, but on the view, on the content type, where? If anyone could give me some direction on where to start looking, I would greatly appreciate it. Thanks

• Which faces technology for use with GlassFish 2.1 and NetBeans 6.7?

  - by SteJav

  I'm running GlassFish 2.1 and using NetBeans 6.7. I'd like to create a web interface to my data using JSF 1.2. Trouble is, I'm not sure which 'faces' technology to learn (that includes some good documentation). JBoss/RichFaces seem pretty good on documentation, but I'm using GlassFish. Any thoughts? The choices appear overwhelming: Tomahawk Tobago Trinidad ICEfaces RCFaces Netadvantage WebGalileoFaces QuipuKit BluePrints Woodstock JBoss RichFaces Ajax4jsf ILOG Oracle ADF G4JSF Simplica Backbase jenia4faces VisualWebPack DynaFaces IBM Impl Dinamica Mojarra PrimeFaces jQuery OpenFaces ZK ExtJS Anybody had any experience with any of the above and found the documentation to be clear to a beginner? Being a JSF/Web beginner, I tried some ICEFaces, Mojarra tutorials and had a go at getting RichFaces working with NBeans and GlassFish, but no luck. Lots of XML complaints. I'm clearly missing some huge chunks of configuration, but I can't find any documentation to help me. Any suggestions would be much appreciated :-)

• Javascript hasOwnProperty does not work under Google Chrome

  - by WebRookie

  I am currently working with some help and it has been going well, until this incident. function runCommand(commandString) { commands = new Object(); commands.clear = function(){ $('#terminal').html('') } parameters = commandString.split(" "); command = parameters.shift(); if( commands.hasOwnProperty(command)){ commandscommand; } else { $('#terminal').append(command+' command not recognized.'+''); } } The person who was helping me made this function, so I could run the "terminal-like" browsers that I needed to work on. It works fine when using Firefox, heres an example: guest@shell:/$ sudo make me sandwich sudo command not recognized. guest@shell:/$ clear *clears* guest@shell:/$ clear But under google chrome this happen: guest@shell:/$ sudo make me sandwich sudo command not recognized. guest@shell:/$ clear clear command not recognized. I believe that it has something to do with "commands.hasOwnProperty(command)" that is preventing it from working properly. I am using JQuery the javascript library to build the website, and I need to know how to solve this problem, or an alternative.

• Visual Studio 2008 Unresponsive When Opening JavaScript Files

  - by lush

  I'm starting a new ASP.NET project that I'm trying to use some jQuery with, but whenever I try to open .js file (blank or containing a few lines of javascript) in Visual Studio, it often hangs; showing the .js filename in a new tab, but the actual text editor window showing whatever was drawn to the screen before opening the .js file. Eventually, after closing and re-opening, it will open in the text editor, but the font is always something like 10pt Arial. Even after changing this in VS options, the next re-launch of Visual Studio yields the same results. Has anyone else experienced hang, unresponsiveness, wonkiness from Visual Studio with JavaScript files?

• ASP.NET MVC - How do I implement validation when using Data Repositories? (Visual Basic)

  - by rockinthesixstring

  I've built a UserRepository interface to communicate with my LINQ to SQL Data layer, but I'm trying to figure out how to implement validation. Here is what my AddUser subroutine looks like Public Sub AddUser(ByVal about As String, ByVal birthdate As DateTime, ByVal openid As String, ByVal regionid As Integer, ByVal website As String) Implements IUserRepository.AddUser Dim user = New User user.About = about user.BirthDate = birthdate user.LastSeen = DateTime.Now user.MemberSince = DateTime.Now user.OpenID = openid user.RegionID = regionid user.UserName = String.Empty user.WebSite = website dc.Users.InsertOnSubmit(user) dc.SubmitChanges() End Sub And then my controller will simply call AddUser(...) But I haven't the foggiest idea on how to implement both client side and server side validation on this. (I think I would prefer to use jQuery AJAX and do all of the validation on the server, but I'm totally open to opinions)

• Where is a Web Development Career fueled by Passion? [closed]

  - by JMC Creative

  Quick Background Since learning basic html 5 years ago, I've become completely obsessed with the technology, the logic, and the thrill of solving problems involved with building websites. I am still stuck at a thoroughly non-programming type job, but would really like to move into the field of web programming/design. I have no educational background in the field (was trained as a fine artist and tutor), but in the past few years have progressed fully self-taught (and self-motivated) from html to css to php, mysql, jquery, and am now building rich web applications. The Question How can I prove to a company that even though I have no education, I have a passion to learn whatever is thrown my way? ...That essentially I would come at every issue with not only knowledge, but with a passionate desire to solve it, whether that means tackling a new language or debugging code for hours at a time? p.s. Sorry for the stupid title.
