  • HTML5 drag & drop: The dragged element content is missing in Webkit browsers.

    - by Cibernox
    I'm trying to implement something similar to a cart where you can drop items from a list. This items (<li> elements) has some elements inside (divs, span, and that stuff). The drag and drop itself works great. But the dragged element's image doesn't show its content in Webkit browsers. My list element has a border an a background color. In Firefox, the image is the whole item. In Webkit browsers, only the dragged element without content. I see the background and border, but without text inside. I tried to make a copy of the element and force it to be the image, but doesn't work. var dt = ev.originalEvent.dataTransfer; dt.setDragImage( $(ev.target).clone()[0], 0, 0); I have a simplified example that exhibit the same behavior: http://jsfiddle.net/ksnJf/1/

Uggggghhh how to resolve this?

  • Why is this consider bad practice? or is it? (ASP.Net)

    - by user318573
    Would this code be considered bad practice: <div id="sidebar"> <% =DisplayMeetings(12) %> </div> This is a snippet of code from the default.aspx of a small web app I have worked on. It works perfectly well, runs very fast, but as always, I am aware of the fact that just because it works, doesn't mean it is OK. Basically, the DisplayMeetings subroutine outputs a bunch of formatted HTML (an unordered list actually), with no formatting, just the requisite html, and then my CSS performs all the necessary formatting. The data for generating the list comes from an SQL server database (the parameter controls how many rows to return) and I am using stored procedures and datareader for fast access. This keeps my front-end extraordinary simple and clean, imho, and lets me do all the work in VB or C# in a separate module. I could of course use a databound repeater (and probably 6 or more other methods) of accomplishing the same thing, but are they any better? Other than loosing the design-time features of VS2010?

  • AS3 get closest date to today

    - by fana
    Hi, I have a XML file with a few concert dates. In my flash/AS3 file, I would like to show only the up coming event, relative to current date. Like this: Event 01: 30-05-2010 Event 02: 02-06-2010 Event 03: 05-06-2010 Today is 28-05-2010, so I need to list Event 01. On 01-06-2010 I need to list Event 02. I have the basic AS3 code for listing the XML working, but I'm having trouble filtering the result. Any ideas? Thanks.

  • Netbeans Intellisense for Rails

    - by irishfury
    Has anybody figured out a way to make the Netbeans intellisense for ruby and rails better? It either has too many options in the list (which I understand is a problem since it is a dynamic language). Or it has no options in the list, as if it is not dynamic enough to find everything. Are there any hacks to make it better, or is this just something that needs to be improved within the Netbeans source code? I'm currently using 6.8. Please spare me the posts about how I don't really need to use intellisense, and I should use vim or emacs. I'm sure the vim programmers are 10 times more productive than me with all their cool shortcuts, but I have no desire to learn these tools.

  • Many-to-many relationship in oop

    - by Manu
    what is best way to model many-to-many relationship? lets say we have a two classes , Team and Player any given Player can be in multiple Team s any Team can have as many Player s as they like I like to call methods like playerX.getTeamList() to get the list of all the Team s he/she is in teamY.getPlayerList() to get the list of all the Player s in the team (or have some other way to do this effectively) I can think of two ways of doing this , but they just don't feels like good oop pattens. can you think of any good ways , perhaps a design patten ?

  • Why the only hidden field that is being filled from GET action is not being passed in model?

    - by user1807954
    Sorry for the long title, I didn't know how to make it any shorter. My code: My model: public class CarFilter { public String carMake { get; set; } public String carModel { get; set; } public String carEdition { get; set; } . . . public String SortBy { get; set; } } public class CarSearch : CarFilter { public List<Car> Car { get; set; } } My controller: public ActionResult SearchResult(CarSearch search) { var cars = from d in db.Cars select d; if (Request.HttpMethod == "POST") { search.SortBy = "Price"; } search.Car = new List<Car>(); search.Car.AddRange(cars); var temp = new List<CarSearch>(); temp.Add(search); return View(temp); } My Index view (where user filters results): @model IEnumerable<Cars.Models.CarSearch> @using (Html.BeginForm("SearchResult", "Home", FormMethod.Post)){..forms and other stuff..} My SearchResult view (where user sees the results of filtration): @model IEnumerable<Cars.Models.CarSearch> @using (Html.BeginForm("SearchResult", "Home", FormMethod.Get)) { @Html.Hidden("carMake") @Html.Hidden("carModel") @Html.Hidden("carEdition") . . . @Html.Hidden("SortBy", temp.SortBy) <input name="SortBy" class="buttons" type="submit" value="Make"/> My goal What I'm trying to do is when user clicked on sort by Make it will have to GET back all the variables in hidden field back to the SearchResult action in order to sort the result (same filtered results). Result Is: <input id="SortBy" name="SortBy" type="hidden" value=""/>. The value is null and it's not being passed but all the other hidden fields such as carMake and etc have value. But when I use foreach it works perfect. Question Why is this like this? the SortBy is in the same model class as other fields in the view. The only difference is that SortBy is not being filled in the Index view with other fields, instead it's being filled in controller action. What is the explanation for this? Am I missing any C# definition or something such as dynamic objects or something?

  • Django: Save an uploaded file to a FileField

    - by David Wolever
    I feel a little stupid for having to ask this… But I can't seem find it documented anywhere. If I've got a Model with FileField, how can I stuff an uploaded FILE into that FileField? For example, I'd like to do something like this: class MyModel(Model): file = FileField(...) def handle_post(request, ...): mymodel = MyModel.objects.get(...) if request.FILES.get("newfile"): mymodel.file = request.FILES["newfile"] But that doesn't appear to work.

  • Javascript / Jquery Tree Travesal question

    - by Copper
    Suppose I have the following <ul> <li>Item 1</li> <li>Item 2 <ul> <li>Sub Item</li> </ul> </li> <li>Item 3</li> </ul> This list is auto-generated by some other code (so adding exclusive id's/class' is out of the question. Suppose I have some jquery code that states that if I mouseover an li, it gets a background color. However, if I mouseover the "Sub Item" list item, "Item 2" will be highlighted as well. How can I make it so that if the user mouses over "Sub Item" it only puts a background color on that and not on "Item 2" as well?

  • using different string files in android

    - by boreas
    I'm porting my iPhone app to android and I'm having a problem with the string files now. The app is a translation tool and users can switch the languages, so all the localized strings are in both languages and they are independent from what locale the OS is running. For iOS version I have different files like de.strings, en.strings and fr.strings and so on. For every target with specified language pair I read the strings from the string tables, e.g. for de-fr I will include de.strings and fr.strings in project and set the name of the string tables in the info-list file and read strings from them. In the end I have one project containing different targets (with different info-list files) and all are well configured. I'm intending to do the same on android platform, but Is only one strings.xml allowed per project? How do I set different build target? How do I specify per target which strings.xml it should read?

  • javascript ul button dropdown crashes after if doing more than 1 button

    - by Apprentice Programmer
    So i have a button drop down list that i want users to select a choice, and basically the button will return the users selection.Pretty straight forward, tested on jsFiddle and works great. Using ruby on rails btw, so i'm not sure if it might conflicting the way rails handle javascript actions. Heres the code: <%= form_for(@user, :html => {:class => 'form-horizontal'}) do |f| %> <fieldset> <p>Do you have experience in Business? If yes, select one of the following: <div class="input-group"> <div class="input-group-btn btn-group"> <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">Select one <span class="caret"></span></button> <ul class="dropdown-menu"> <li ><a href="#">Entrepreneurship</a></li> <li ><a href="#">Investments</a></li> <li ><a href="#">Management</a></li> <li class="divider"></li> <li ><a href="#">All of the Above</a></li> </ul> </div><!-- /btn-group --> <%= f.text_field :years_business , :class => "form-control", :placeholder => "Years of experience" %> </div> Now there are 2 more of these, and basically what happens is that if I select an item for the first time from the dropdown list, everything works great. But the moment I select the same button/or new button, the page immediately kind of refreshes, they selected value will not show up after the list drops down and user selects a value. I viewed the page source and added additional javascript src and types, but still doesnt work. the jquery code: jQuery(function ($) { $('.input-group-btn .dropdown-menu > li:not(.divider)').click(function(){ $(this).closest('ul').prev().text($(this).text()) }) }); Any suggestions what is causing the problem?? The jsfiddle link is here: http://jsfiddle.net/w4s8u/7/

  • How to implement collection with covariance when delegating to another collection for storage?

    - by memelet
    I'm trying to implement a type of SortedMap with extended semantics. I'm trying to delegate to SortedMap as the storage but can't get around the variance constraints: class IntervalMap[A, +B](implicit val ordering: Ordering[A]) //extends ... { var underlying = SortedMap.empty[A, List[B]] } Here is the error I get. I understand why I get the error (I understand variance). What I don't get is how to implement this type of delegation. And yes, the covariance on B is required. error: covariant type B occurs in contravariant position in type scala.collection.immutable.SortedMap[A,List[B]] of parameter of setter underlying_=

    I am using SimpleMembership for user login stuff in my web application. I wrote a console that actually access my web application classes to avoid duplicate code. However, since my console application doesn't have anything related to user sessions the Login method doesn't work. But is there a way to validate a user only using the SimpleMembership? In case i have to do it manually.. how can i do it ?
