• HTML: How to get a child element to show behind (lower z-index) than its parent

  - by dclowd9901

  I need for a certain dynamic element to always appear on top of another element, no matter what order in the DOM tree they are. Is this possible? I've tried z-index (with position: relative), and it doesn't seem to work. I hate to be vague, but this is the simplest way I can think of asking this question without explaining its purpose ad nauseum. So, to recap, I need <div class="a"> <div class="b"></div> </div> <div class="b"> <div class="a"></div> </div> To display exactly the same when rendered. And for flexibility purposes (I'm planning on distributing a plugin that needs this functionality), I'd really like to not have to resort to absolute or fixed positioning.

• Drag big picture in small layer?

  - by Tronic

  Hi, I need a plugin for jquery or another js framework, where I can define a small div where i can drag around a big picture, so i get only a clipping of the picture. any ideas? edit: i try to explain i have a small div, like 600px x 450px. this div behaves like a clipping window for a big picture with like 3000px x 2000px. so i only see a specific cutout of the big picture. and i need to drag that big picture around in this small clipping window! c

• Attachment_fu: can't disable :partition option

  - by Nathan Long

  I'm trying to use the Attachment_Fu plugin in a Rails project, and want to customize the paths where uploaded files are saved. The documentation shows this option: :partition # Whether to partiton files in directories like /0000/0001/image.jpg. Default is true. (The 0001 part is an ID from a table.) I don't want that, so I set the partition option to false, like so: class Photo < ActiveRecord::Base has_attachment :content_type => :image, :storage => :file_system, :max_size => 500.kilobytes, :resize_to => '320x200', :thumbnails => {:thumb => '100x100>' }, :partition => false validates_as_attachment end ...but the :partition => false option has no effect. Has anybody else encountered this problem? How did you fix it?

• jQuery Tablesorter - disabled headers show progress bar, sortEnd never triggered

  - by McGirl

  I'm combining Tablesorter's 'disable headers using options' function and the 'trigger sortStart / sortEnd' function and have run into an issue. The following code works fine for the most part, BUT: when you click on a disabled header, the progress-indicating #overlay div appears and never goes away. <script type="text/javascript" id="js"> $(document).ready(function() { // call the tablesorter plugin, the magic happens in the markup $("#projectTable").tablesorter({ // pass the headers argument and assing a object headers: { // assign the secound column (we start counting zero) 1: { // disable it by setting the property sorter to false sorter: false }, // assign the third column (we start counting zero) 2: { // disable it by setting the property sorter to false sorter: false } } }); //assign the sortStart event $("#projectTable").bind("sortStart",function() { $("#overlay").show(); }).bind("sortEnd",function() { $("#overlay").hide(); }); }); </script> Any ideas on how I could fix this so that nothing at all happens when the disabled headers are clicked? Thanks!

• Implementing a multi-state planner

  - by MoominTroll

  I've been asked to develop a system wherein employees can mark on a form their availability on a given day of the week - for instance an employee could mark themselves as available on a given time on a given week, and unavailable on some other time. It looks a little like this: Currently this works by rendering checkboxes within the table, picking up click events in each cell and marking the checkbox and hence the cell appropriately. I'm using the JQuery "click n drag checkbox" plugin from here. However, I've been informed that there could well be more than two states for a given cell (for instance available, unavailable, available in a given circumstance), in which case binding to a checkboxes checked value isnt going to be a lot of help. I've never used javascript or asp.net before and am unsure as to the best way to approach this problem. Ideally I could stick a data structure behind each cell which I could update to a certain state and then get my cell colour by binding to this - however I'm at something as a loss as how to best achieve this.

• different small js files per page VS. 1x site-wide js file?

  - by Haroldo

  Different pages of my site have different js needs (plugins mainly), some need a lightbox, some dont, some need a carousel, some dont etc. With regards to pageloading speed should i option 1 - reference each js file when it is needed: so one page might have: <script type="text/javascript" src="js/carousel/scrollable.js"></script> <script type="text/javascript" src="js/jquery.easydrag.js"></script> <script type="text/javascript" src="js/colorbox/jquery.colorbox-min.js"></script> and another have: <script type="text/javascript" src="st_wd_assets/js/carousel/scrollable.js"></script> <script type="text/javascript" src="st_wd_assets/js/typewatch.js"></script> option 2 - combine and compress into one site_wide.js file: so each page would reference: <script type="text/javascript" src="js/site_wide.js"></script> there would be unused selectors/event listeners though, how bad is this? I would include any plugin notes/accreditations at the top of the site_wide.js file

• In Jenkins, how to checkout a project into a specific directory (using GIT)

  - by viebel

  Sorry for the 'svn' style - we are in a process of migration from SVN to GIT (including our CI Jenkins environment). What do we need is to be able to make Jenkins to checkout (or should I say clone?) the GIT project (repository?) into a specific directory. We've tried some refspecs magic but it wasn't to obvious to understand and to use successfully. Furthermore, if in the same Jenkins project we need to checkout several private GitHub repositories into several separate dirs under a project root. How can we do it please? We have GitHub plugin installed. Hope we've phrased the things right.

• Fade out text value inside of text field using jQuery

  - by Dwayne

  I am not entirely sure if this is possible or not, I am pretty knowledgeable when it comes to jQuery and JavaScript in general, but this one has me stumped. I've created a simple plugin that clears a text input on focus and then displays the default value if nothing has been entered. Is it possible to fade out just the text itself inside of the text input, and not the whole field itself? All attempts seem to result in the text field itself fading out and eventually hiding the element from view. I did come up with a solution of using spans containing the default value and absolutely positioning them over the text input, hiding and showing them depending if a user has entered any text or not. I would much rather a much straightforward approach if one exists.

• Nested sql queries in rails when :has_and_belongst_to_many

  - by Godisemo

  Hello, In my application I the next task that has not already been done by a user. I have Three models, A Book that has many Tasks and then I have a User that has has and belongs to many tasks. The table tasks_users table contains all completed tasks so I need to write a complex query to find the next task to perform. I have came up with two solutions in pure SQL that works, but I cant translate them to rails, thats what I need help with SELECT * FROM `tasks` WHERE `tasks`.`book_id` = @book_id AND `tasks`.`id` NOT IN ( SELECT `tasks_users`.`task_id` FROM `tasks_users` WHERE `tasks_users`.`user_id` = @user_id) ORDER BY `task`.`date` ASC LIMIT 1; and equally without nested select SELECT * FROM tasks LEFT JOIN tasks_users ON tasks_users.tasks_id = task.id AND tasks_users.user_id = @user_id WHERE tasks_users.task_id IS NULL AND tasks.book_id = @book_id LIMIT 1; This is what I Have done in rails with the MetaWhere plugin book.tasks.joins(:users.outer).where(:users => {:id => nil}) but I cant figure out how to get the current user there too, Thanks for any help!

• Do I have to release modifications made to a GPL v2 CMS?

  - by John McCollum

  If we use a CMS that is covered by the GPL (v2), do we have to re-release the source code of the CMS if we make modifications to the core? The GPL v2 states: The GPL does not require you to release your modified version. You are free to make modifications and use them privately, without ever releasing them. This applies to organizations (including companies), too; an organization can make a modified version and use it internally without ever releasing it outside the organization. But if you release the modified version to the public in some way, the GPL requires you to make the modified source code available to the program's users, under the GPL. The grey area for me here is the part that states "if you release the modified version to the public in some way" - does displaying a website to the public count as "releasing it to the public"? What about if a custom plugin is written which integrates with the CMS - are we required to release the source? Does this count as a modification?

• Avoid multiple autocomplete calls by wrapping it with SetTimeOut

  - by pixelboy

  Here's my issue : using an autocomplete jQuery plugin, I'd like to avoid multiple ajax requests when user strikes his keynoard by surrounding the $('#query1').autocomplete({ serviceUrl:'/actions/autocomplete?population=salon', minChars:3, maxHeight:300, width:200, clearCache:true, onSelect: function(suggestions,data){ $(".btn1").attr("href", "${pageContext.request.contextPath}/actions/espaceClients?participantId=" + data) } }); with something like var search = false; $('#query1, #query2, #query3').keyup(function(){ if (!search){ search = true; } if (search) { search = false; autocompleteThem(); } }); A you can see, above code is stupid, but it kinda shows what i'm trying to do. In simple words, if user dosen't type anything else in a certain period of time, then you can call autocomplete. I hope i'm being clear, as my brains are a mess...

• prevent hover set by the CSS

  - by meo

  I try to prevent the Browser from using the :hover effect of the CSS. $("ul#mainFilter a").hover( function(o){ o.preventDefault(); ...do my stuff... }, function(o){ o.preventDefault(); ...do my stuff... }); I tired it with return false; to but it does not work. Does anyone know how to do this? due the answers i give you some more nfo: I have set the a and a:hover styles, in my CSS already. Now if JS is available on the clients machine, i want to overwrite the effect with a smoother one. (using jQuery color plugin) As mentioned by fudgey, a work around would be to set the style (using .css()) but i would have to overwrite every single effect specified in the CSS (see here: http://jsfiddle.net/raPeX/1/ ). I am looking for a generic solution.

• Sanitizing CSS in Rails

  - by Erik

  Hello! I want to allow the users of a web app that I'm building to write their own CSS in order to customize their profile page. However I am aware of this opening up for many security risks, i e background: url('javascript:alert("Got your cookies! " + document.cookies'). Hence I am looking for a solution to sanitize the CSS while still allowing as much CSS functionality as possible for my users. So my questions if anyone anyone knows of a gem or a plugin to handles this? I've googled my brains out already so any tips would be really appreciated!

• GWT tries to load a deleted module

  - by Dmitry

  I am using Eclispe with Google plugin for AppEngine and GWT. Recently I created a test GWT module, but eventually it has been deleted from the project and I can not find any sign of it in the project now. However, whenever I run the web app locally, I get in console the following message: Loading modules com.piq.exemity.Test [ERROR] Unable to find 'com/XXXXXX/Test.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source? Has anyone got any idea where it can be hiding?

• Zip up groups of webpages for viewing in the browser

  - by Arlen Beiler

  I think there should be a standard for saving and viewing bunches of webpages as a website. For instance, say I have a whole bunch of pages, such as I get from the WordPress plugin "Really Static" (which saves the entire site), and I have all the links start with a slash (to make linking to supporting files easier). Now, I can't really use those links if I am reading it from the file system. If there would be a standard where we could zip up files, give them a unique extension (like "hzip" for html zip), and open the file with any browser, which would display it as though the root of that file were the root of the pages. "file://examplefile.hzip/" The links would then all work. This would really help sharing and copying groups of webpages. Is this a good idea? A bad one? What do you think?

• Event handling to detect if user clicks a 'Like' button in XFBML page

  - by Simon_Weaver

  I have a Facebook connect app / canvas IFrame app which has a Like control for a fanpage. I'd like to detect when the user clicks the Like button to be able to display additional info (a discount coupon code). I'm using the latest Javascript API but the events that can be handled doesn't seem to include detection of social widget controls. The documentation for the Like Plugin doesn't show any events. However I know its definitely possible because if I have two Like buttons on a page they both instantly update each other if I like or unlike whatever it is.

• Is there a "vim runtime log"?

  - by Somebody still uses you MS-DOS

  Sometimes I try a customization/command in my vimrc. Everything seens to be correct, but it just doesn't work. It's difficult to know what's happening when vim starts, and know which command failed or not, so it's really difficult to debug what can be causing a problem in my vimrc. It's a trial-error approach, which is time consuming and really a PITA. For example, I'm having problems with snipmate plugin in some files and just don't have a clue on how to discover the problem. Is there a "runtime log" when vim starts, telling which commands it executed, which ones failed and such? This would help me a lot.

• Ruby on Rails controller-view refactoring

  - by Dimitar Vouldjeff

  Hello, In my app I am using the ym4r-gm plugin, which allows you to play with the Google Maps API... I put the map "setup" in the controller: @map = GMap.new("div_map") @map.control_init(:large_map => true, :map_type => true) @map.center_zoom_init([47.0, 26.0], 7) ... And only render @map in the view. So my first question is whether I am using the right approach of "diving" this code? And the second question is: I have to models, which are rendering the same map (only the resources are different). Where should I put my refactored method that renders the map? In the application controller, maybe? Thanks in advance, I hope you will understand me!

• Convert HTML tag to lowercase

I use $('#output').text($('#container').html()); But IE6 outputs all the code in uppercase: <TABLE> <TR> <TD>test</TD> </TR> </TABLE> How can I convert HTML tags to lowercase using jQuery? Would be useful to have a plugin that could recursively go trough the DOM-tree.

• deploying flex on tomcat

  - by ron

  Hello, I am using Flash builder 4 (SDK3.5) to create my flex program. I want to deploy this program and load it to a tomcat server. I configure my "flex server" root folder and other parameters in the project properties. The problem is, that i don't know how to make it generic. e.g. my friend's tomcat is installed in other directory on the computer. I know that in eclipse i can run the server and tomcat from the IDE. I can't see how i do it in Flash builder plugin for eclipse 4. There is a server configuration, but there isn't adapter for tomcat. Any ideas? thanks.

• Best anti boss tricks to hide your private page navigation from your desktop.

  - by systempuntoout

  This question is slightly related to programming and it's kinda lame, i know; but i saw many funny things in these years and i'm looking for new tricks from you. I'm talking about methods to fast-hide\camouflage not job related web pages on your desktop when boss arrives like a ghost\ninja behind your shoulders. I know how much can be frustrating, programming hard for ten hours and then been caught by your boss watching XKCD during a 2 minutes break. I think the most common anti boss trick is the evergreen CTRL+TAB, but you have to be fast and your left hand has to be near the keyboard. I saw pitch black brightness on Lcd (how can you pretend to program on that?) or custom sized browser to fit a little space just below the IDE. My favourite one at the moment is using fire gesture plugin with FF; with a micro gesture you can hide FF to your tray in a blink of an eye. Do you have any trick to share?

• Can a signed Java Applet/Web Start manipulate content in a cross-site IFRAME?

  - by etoleb

  Is it possible for a signed Java Applet or Web Start app to write to the DOM of an IFRAME under a different domain? Does the fact that they're a signed applet/javaws allow them to ignore browsers' standard cross-browser security? If this does work, how well is it supported across the major browsers? Thanks! EDIT: My motivation is to add a browser plugin-like tool to third-party websites I don't control. It's not required that I use Java at all---any ideas or suggestions are encouraged.

• How to debug/reformat C printf calls with lots of arguments in vim?

  - by Costi

  I have a function call in a program that I'm maintaining has 28 arguments for a printf call. It's printing a lot of data in a CSV file. I have problems following finding where what goes and I have some mismatches in the parameters types. I enabled -Wall in gcc and I get warnings like: n.c:495: warning: int format, pointer arg (arg 15) n.c:495: warning: format argument is not a pointer (arg 16) n.c:495: warning: double format, pointer arg (arg 23) The function is like this: fprintf (ConvFilePtr, "\"FORMAT3\"%s%04d%s%04d%s%s%s%d%s%c%s%d%c%s%s%s%s%s%s%s%11.lf%s%11.lf%s%11.lf%s%d\n", some_28_arguments_go_here); I would like to know if there is a vim plugin that highlights the printf format specifier when i go with the cursor over a variable. Other solutions? How to better reformat the code to make it more readable?

• Reloading Rails Directories: Not Lib!

  - by yar

  I have checked out several questions on this, including all of those you see next to the question. Unfortunately, I'm not working with a plugin, and I don't want to work in lib. I have a directory called File.join(Rails.root, 'classes') and I'd like the classes in this directory to reload automatically in dev. In my environment.rb I have this line config.load_paths << File.join(Rails.root, 'classes') which works fine and blows up if the path isn't there. The reloading line in my development.rb also works fine require_dependency File.join(Rails.root, 'classes', 'blah.rb') which blows up if the file is not there (a good sign). However, the file doesn't reload. This all works if the file is in the root of lib and I use the require_dependency line, but my whole point is to get stuff out of lib as suggested here.
