  • Is it possible to do A/B testing by page rather than by individual?

    - by mojones
    Lets say I have a simple ecommerce site that sells 100 different t-shirt designs. I want to do some a/b testing to optimise my sales. Let's say I want to test two different "buy" buttons. Normally, I would use AB testing to randomly assign each visitor to see button A or button B (and try to ensure that that the user experience is consistent by storing that assignment in session, cookies etc). Would it be possible to take a different approach and instead, randomly assign each of my 100 designs to use button A or B, and measure the conversion rate as (number of sales of design n) / (pageviews of design n) This approach would seem to have some advantages; I would not have to worry about keeping the user experience consistent - a given page (e.g. www.example.com/viewdesign?id=6) would always return the same html. If I were to test different prices, it would be far less distressing to the user to see different prices for different designs than different prices for the same design on different computers. I also wonder whether it might be better for SEO - my suspicion is that Google would "prefer" that it always sees the same html when crawling a page. Obviously this approach would only be suitable for a limited number of sites; I was just wondering if anyone has tried it?

  • Possible defect with jQuery ':checked' selector (finding checked checkbox when there are none)

    - by Mphammad Ashour
    Found a strange thing. The following code is supposed to set a default value for a UI element based on whether one of a group of checkboxes (all having attribute name="privacy") is checked (in say, a form postback). If there is no value in the HTML sent by the server (the form is not a postback), the default value should be firstMenuItemKey. Otherwise, it should be the one checked in the underlying HTML. However, while this works on the first call to the URL that includes the form, a refresh of the page will set the value of defaultPrivacyValue to one of the privacy checkboxes'. I've checked that the server isn't checking the checkbox before the script runs (it's not). I've also checked whether somewhere else in the script is checking the checkbox (it's not). var defaultPrivacyValue = firstMenuItemKey; $('input[name=privacy]:checked').each(function() { defaultPrivacyValue = $(this).next().find('.name').text(); }); selectMenuItem(defaultPrivacyValue); When I chaged the selector to 'input[name=privacy][checked=checked]' it worked as expected. Is this a defect in the jQuery implementation of DOM retrieval based on the ':checked' selector???? I'm using jQuery 1.4.2. Thanks for any help you can give.

  • Attachment_fu file saving problem

    - by Anand
    Attachment_fu plugin is kind of old, but I have to modify an old app and I can't use another plugin like paperclip etc. So here's the code without further ado Submissions table structure --------------------------- | content_type | varchar(255) | YES | | NULL | filename | varchar(255) | YES | | NULL app/models/submission.rb ------------------------ has_attachment :storage => :file_system, :path_prefix => 'public/submissions', :max_size => 2.megabytes, :content_type => ['application/pdf', 'application/msword', 'text/plain'] app/models/user.rb ------------------ has_one :submission, :dependent => :destroy app/views/user/some_action.html.erb ----------------------------------- <% form_for :user, :url => { :action => "some_action" }, :html => {:multipart => true} do |f| %> .... <%= file_field_tag "submission[uploaded_data]" %> <%end%> app/controllers/user_controller.rb ---------------------------------- @user = User.find_user(session[:user_id]) @submission = @user.submission if request.post? @submission.uploaded_data = params[:submission][:uploaded_data] end When the form is submitted, the database fields "content_type" and "filename" get updated and display the correct values, but the file does not appear in public/submissions/ directory. I have checked the permissions on the submissions directory. What am I missing? Many Thanks

  • JSF 2.0 Dynamic Views

    - by Robe Eleckers
    Hello, I'm working on a web project which uses JSF 2.0, PrimeFaces and PrettyFaces as main frameworks / libraries. The pages have the following (common) structure: Header, Content, Footer. Header: The Header always contains the same menu. This menu is a custom component, which generates a recursive html <ul><li> list containing <a href="url"> html links, this is all rendered with a custom renderer. The link looks like 'domain.com/website/datatable.xhtml?ref=2'. Where the ref=2 used to load the correct content from the database. I use prettyfaces to store this request value in a backingbean. Question 1: Is it ok to render the <a href> links myself, or should I better add an HTMLCommandLink from my UIComponent and render that in the encodeBegin/End? Question 2: I think passing variables like this is not really the JSF 2.0 style, how to do this in a better way? Content: The content contains dynamic data. It can be a (primefaces) datatable, build with dynamic data from the database. It can also be a text page, also loaded from the database. Or a series of graphs. You got the point, it's dynamic. The content is based on the link pressed in the header menu. If the content is of type datatable, then I put the ref=2 variable to a DataTableBean (via prettyfaces), which then loads the correct datatable from the database. If the content is of type chart, I'll put it on the ChartBean. Question 3: Is this a normal setup? Ideally I would like to update my content via Ajax. I hope it's clear :)

  • CSS: Making two transparent images overlapping

    - by Pierre
    Hi all, I'm trying to make two transparent images (having the same size/dimension ) overlapping into a div at their top left corner. I tried: <html xmlns="http://www.w3.org/1999/xhtml"> <body> <div style="margin:20px;"> <div id="main" style="overflow:hidden;background-color:red;width:400px;height:400px;border:3px solid blue;"> <img src="myimage1.png" style="position:relative;top:0px;left:0px;z-index:0;"/> <img src="myimage2.png" style="position:relative;top:0px;left:0px;z-index:10;"/> </div> </div> </body> </html> but it doesn't work, the two pictures are concatenated into the parent div. Thanks for your help !

  • Rails routing problem

    - by Steve
    I am new to Rails routing and I currently have a problem and hope someone can explain it to me. I am using Rails 2.3.5 Firstly, let me describe my working-fine code: I have a text example, which has a controller (cars_controller) with an update action (along with some other actions). The update action needs the :id parameter. The edit.html.erb has a form: <% form_for :car, :url = {:controller = 'cars', :action = 'update' } % ... # rest of the form content. In the configuration/routes.rb, I have a self-defined routing rule for update: map.connect 'car/update/:id', :controller = 'cars', :action = 'update' This works fine. Secondly, I change the code. All I change is the self-defined routing rule to map.connect 'car/:action/:id, :controller = 'cars' To me, this rule covers the self-written routing rule. Of course, this rule is also used by other actions such as edit. But the edit.html.erb doesn't work. It complains that update action misses the :id parameter. I have to change the form_for helper to: <% form_for :car, :url = {:controller = 'cars', :action = 'update', :id = @car }% ... # @car is the instance passed to edit view. I know that if missing the :id parameter, update action will complain. What I don't understand is why my first code works (with my self-defined routing rule) but my second code fails. It seems to me that I didn't provide :id parameter in my self-defined routing rule. Anyone has an idea?

  • Need help writing jQuery to loop through table and inject markers into google map?

    - by abemonkey
    I am new to jQuery. I've done some simple things with it but what I am attempting now is a over my head and I need some help. I am building a locator for all the firearms dealers in the US for a client. I am working within Drupal. I have a proximity search by zip code that works great. If you search by zip a list of paginated results shows up in an html table that can by paged through via ajax. I would like a map to be above this list with markers corresponding to the names and addresses being listed. I already have all the lat and long values in the table results. I want the script to update the markers and automatically zoom to fit the markers in the view when a user changes the sort order of the table or pages through the results. Also, I'd like to have a hover highlight effect over the rows of the table that simultaneously highlight the corresponding marker, and have a click on the table row equal a click on a marker that pops up a marker info window to be populated using jQuery to read the name and address fields of the table. Hope this all makes sense. I know I'm putting a lot out there, I'm not asking for someone to write the whole script, just wanted to give as many details as possible. Thanks for any help. I'm just lost when it comes to looping and moving data around. If you want to check out what I have so far on the project please visit: www.axtsweapons.com and login with the username: "test" and the password: "1234" and then visit this direct link: www.axtsweapons.com/ffllocator. For just a simple page that would be easy to manipulate and play with goto: http://www.axtsweapons.com/maptest.html Thanks!

  • XML Pretty Printer Missing 2 Key Edge Cases

    - by viatropos
    Using this xslt file found on this blog to pretty print xml using Nokogiri, everything almost works, but to the point where I can't use it for HTML. First, if a node is empty, it turns it into a self closing node, so: <textarea></textarea> gets converted to <textarea/> But that messes up the html tree when rendered. Second, if the node just has text, the text isn't tabbed, and the closing node isn't tabbed, so: <li> <label>some text</label> </li> becomes: <li> <label>some text </label> </li> ...but it would ideally be: <li> <label> some text </label> </li> Does anyone who's pro at XSLT know a quick fix for this?

  • How to implement custom JSF component for drawing chart?

    - by Roman
    I want to create a component which can be used like: <mc:chart data="#{bean.data}" width="200" height="300" /> where #{bean.data} returns a collection of some objects or chart model object or something else what can be represented as a chart (to put it simple, let's assume it returns a collection of integers). I want this component to generate html like this: <img src="someimg123.png" width="200" height="300"/> The problem is that I have some method which can receive data and return image, like: public RenderedImage getChartImage (Collection<Integer> data) { ... } and I also have a component for drawing dynamic image: <o:dynamicImage width="200" height="300" data="#{bean.readyChartImage}/> This component generates html just as I need but it's parameter is array of bytes or RenderedImage i.e. it needs method in bean like this: public RenderedImage getReadyChartImage () { ... } So, one approach is to use propertyChangedListener on submit to set data (Collection<Integer>) for drawing chart and then use <o:dynamicImage /> component. But I'd like to create my own component which receives data and draws chart. I'm using facelets but it's not so important indeed. Any ideas how to create the desired component? P.S. One solution I was thinking about is not to use <o:dynamicImage/> and use some servlet to stream image. But I don't know how to implement that correctly and how to tie jsf component with servlet and how to save already built chart images (generating new same image for each request can cause performance problems imho) and so on..

  • Rails does not display error messages on a form in a custom method

    - by slythic
    Hi all, I've created a custom method called checkout in my app. I create an order (which is done my adding products to my "cart"), assign it to my client, and then I head to my checkout screen where I confirm the items and enter their customer order number and complete the order (submit). Everything works great except that it doesn't display error messages. I'm able to display a flash error notice (seen in complete_order method) when things go wrong but it doesn't specify the details like a normal form would. The error messages should appear if the customer order number is not unique for that client. Below is the custom method (checkout) related code. Order Model: validates_uniqueness_of :customer_order_number, :scope => :client_id Orders_controller: def checkout @order = current_order end def complete_order @order = current_order respond_to do |format| if @order.update_attributes(params[:order]) @order.complete #sets submitted datetime and state to 'complete' flash[:notice] = 'Thank you! Your order is being processed.' format.html { redirect_to( products_path ) } format.xml { head :ok } else flash[:error] = 'Please review your items' #added to confirm an error is present format.html { redirect_to( checkout_path ) } format.xml { render :xml => @order.errors, :status => :unprocessable_entity } end end end And the form in the checkout view: <% form_for @order, :url => { :controller => "orders", :action => "complete_order" } do |f| %> <%= f.error_messages %> <%= f.text_field :customer_order_number, :label => "Purchase Order Number" %> <p> <%= f.submit 'Complete Order', :confirm => 'Are you sure?' %> <small> or <%= link_to 'cancel', current_cart_path %></small> </p> <% end %> Any idea how I can display the specific error messages? Thank you in advance! -Tony

  • What is the single most influential book every programmer should read?

    - by NotMyself
    If you could go back in time and tell yourself to read a specific book at the beginning of your career as a developer, which book would it be? I expect this list to be varied and to cover a wide range of things. For me, the book would be Code Complete. After reading that book, I was able to get out of the immediate task mindset and begin to think about the bigger picture, quality and maintainability.

  • 2 different routes on one page?

    - by Dejan.S
    Hi I'm pretty new with MVC2 or MVC in general. If it's one thing I get caught up with it's routes. Like now I got this scenario. Im going from the regular site to Admin. My navigation is the same partialview on both I just do a check which data to render something like this. <% if (!Request.RawUrl.Contains("Admin")){%> <% foreach (var site in Model) { %> <%= Html.MenuItem(site.BelongSite, "Sida", "Site", site.BelongSite) %> | <%} %> <%} else {%> <%= Html.ActionLink("Konfig", "Konfigurera", "Admin") %> <% } %> My route looks like this routes.MapRoute( "Admin", // Route name "Admin/{action}/{name}", // URL with parameters new { controller = "Admin", action = "konfigurera", name = UrlParameter.Optional } // Parameter defaults ); On my View called Konfigurera I got Edit sites and they use the route above and it works great. The navigation tho dont get no action assigned to it. It's just <a href='Admin/'> The navigation is in the shared folder, and it is a strongly typed. Any Ideas? I been struggling with this for about a hour now Thanks for any input

  • How to store a file on a server(web container) through a Java EE web application?

    - by Yatendra Goel
    I have developed a Java EE web application. This application allows a user to upload a file with the help of a browser. Once the user has uploaded his file, this application first stores the uploaded file on the server (on which it is running) and then processes it. At present, I am storing the file on the server as follows: try { FormFile formFile = programForm.getTheFile(); // formFile represents the uploaded file String path = getServlet().getServletContext().getRealPath("") + "/" + formFile.getFileName(); System.out.println(path); file = new File(path); outputStream = new FileOutputStream(file); outputStream.write(formFile.getFileData()); } where, the formFile represents the uploaded file. Now, the problem is that it is running fine on some servers but on some servers the getServlet().getServletContext().getRealPath("") is returning null so the final path that I am getting is null/filename and the file doesn't store on the server. When I checked the API for ServletContext.getRealPath() method, I found the following: public java.lang.String getRealPath(java.lang.String path) Returns a String containing the real path for a given virtual path. For example, the path "/index.html" returns the absolute file path on the server's filesystem would be served by a request for "http://host/contextPath/index.html", where contextPath is the context path of this ServletContext. The real path returned will be in a form appropriate to the computer and operating system on which the servlet container is running, including the proper path separators. This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive). So, Is there any other way by which I can store files on those servers also which is returning null for getServlet().getServletContext().getRealPath("")

  • Hierarchical object model with property inheritance and event bubbling?

    - by Winston Fassett
    I'm writing a document-based client application and I need a DOM or WPF-like, but non-visual model that: Is a tree composed of elements Can accept an unlimited number of custom properties that get/set any CLR type, including collections. Can inherit their values from their parent Can inherit their default values from an ancestor Can be derived/calculated from other properties, ancestors, or descendants Support event bubbling / tunneling There will be a core set of properties but other plugins may add their own or even create custom documents Supports full inspection by the owning document in order to persist the tree and attributes in an XML format. I realize that's a tall order but I was really hoping there would be something out there to help me get started. Unfortunately WPF DependencyObjects are too closed, proprietary, and coupled to WPF to be of any use as a document model. My needs also have a strong resemblance to the HTML DOM but I haven't been able to find any clean DOM implementations that could be decoupled from HTML or ported to .NET. My current platform is .NET/C# but if anyone knows of anything that might be useful for inspiration or embedding, regardless of the platform, I'd love to know.
