  • Jquery Dropdown queue problem

    - by Sarfraz
    Hello, I have created a drop down with JQuery that can be seen here by clicking the Preview button on top: http://jsbin.com/ubire3/edit It works fine except for one problem. When i hover over the main hover links (blue ones) quickly eg going horizontally quickly hovering each top menu, the some submenus don't close. How do i make it so that even if i hover fast over them all other submenus are closed? Thanks.

  • How to handle javascript & css files across a site?

    - by Industrial
    Hi everybody, I have had some thoughts recently on how to handle shared javascript and css files across a web application. In a current web application that I am working on, I got quite a large number of different javascripts and css files that are placed in an folder on the server. Some of the files are reused, while others are not. In a production site, it's quite stupid to have a high number of HTTP requests and many kilobytes of unnecessary javascript and redundant css being loaded. The solution to that is of course to create one big bundled file per page that only contains the necessary information, which then is minimized and sent compressed (GZIP) to the client. There's no worries to create a bundle of javascript files and minimize them manually if you were going to do it once, but since the app is continuously maintained and things do change and develop, it quite soon becomes a headache to do this manually while pushing out new updates that features changes to javascripts and/or css files to production. What's a good approach to handle this? How do you handle this in your application?

  • Which web solution should I use for my project?

    - by BenIOs
    I'm going to create a fairly large (from my point of view anyway) web project with a friend. We will create a site with roads and other road related info. Our calculations is that we will have around 100k items in our database. Each item will contain some information like location, name etc. (about 30 thing each). We are counting on having a few hundred thousand unique visitors per month. The 100k items and their locations (that will be searchable) will be the main part of the page but we will also have some articles, comments, news and later on some more social functions (accounts, forums, picture uploads etc.). We were going to use Google AppEngine to develop our project since it is really scalable and free (at least for a while). But I'm actually starting to doubt that AppEngine is right for us. It seems to be for webbapps and not sites like ours. Which system (language/framework etc.) would you guys recommend us to use? It doesn't really mater if we know the language since before (we like learning new stuff) but it would be good if it's something that is future proof.

  • JQuery: Read each line of an element

    - by Sarfraz
    Hello, Suppose I have this html markup: <div id="wrapper"> $(function(){ // hide all links except for the first $('ul.child:not(:first)').hide(); $("a.slide:first").css("background-color","#FF9900"); $('ul.parent a.slide').click(function(){ $('ul.parent a.slide').css("background-color","#3399FF"); $('ul.parent a.slide').mouseout(function(){ $(this).css("background-color","#3399FF"); }); $('ul.parent a.slide').mouseover(function(){ $(this).css("background-color","#66CC66"); }); }); }); </div> What is the easiest way to read each line of code present in the div. How do I extract each line of code from that div or loop over each line styling in any way I want. Thanks

  • Many tables for many users?

    - by Seagull
    I am new to web programming, so excuse the ignorance... ;-) I have a web application that in many ways can be considered to be a multi-tenant environment. By this I mean that each user of the application gets their own 'custom' environment, with absolutely no interaction between those users. So far I have built the web application as a 'single user' environment. In other words, I haven't actually done anything to support multi-users, but only worked on the functionality I want from the app. Here is my problem... What's the best way to build a multi-user environment: All users point to the same 'core' backend. In other words, I build the logic to separate users via appropriate SQL queries (eg. select * from table where user='123' and attribute='456'). Each user points to a unique tablespace, which is built separately as they join the system. In this case I would simply generate ALL the relevant SQL tables per user, with some sort of suffix for the user. (eg. now a query would look like 'select * from table_ where attribute ='456'). In short, it's a difference between "select * from table where USER=" and "select * from table_USER".

  • "Othello" game needs some clarification

    - by pappu
    I am trying to see if my understanding of "othello" fame is correct or not. According to the rules, we flip the dark/light sides if we get some sequence like X000X = XXXXX. The question I have is if in the process of flipping 0-X or X- 0, do we also need to consider the rows/columns/diagonals of newly flipped elements? e.g. consider board state as shown in above image(New element X is placed @ 2,3) When we update board, we mark elements from 2,3 to 6,3 as Xs but in this process elements like horizontal 4,3 to 4,5 and diagonal 2,3 to 4,5 are also eligible for update? so do we update those elements as well? or just the elements which have starting as 2,3 (i.e update rows/column/diagonal whose starting point is the element we are dealing with, in our case 2,3?) Please help me understand it

  • Questions about jQuery's getScript()

    - by Nimbuz
    $.getScript("somescript.js", function() { alert('Load Complete'); }); Once loaded, is it cached or is it loaded again if referenced more than once? If an event depends on this file being loaded, will the event be delayed of fail/timeout in case the file takes longer to load or doesn't load? How do I check and do something in case the file fails to load for some reason? Thanks in advance for your help.

  • Tool for making quick UI drafts

    - by Moshe
    I'm looking for a tool that can be used for sketching UI (specifically web UI). The sketches/drafts can look as simple as if it was drawn by hand on a whiteboard. Preferably, this tool should be free/open-source and run on Linux as well as on Windows, but this is not a must. Could you recommend?

  • Overview of mobile browsers and their features?

    - by Janusz
    I'm looking for a comparison of the features of mobile browsers. Most interesting are the default preinstalled browsers. I would love a matrix that shows what device line can do what with their preinstalled browser. There is a list with rendering engines on wikipedia but there should be differences appart from the rendering right?

  • 2d Game Making > Where can someone get Free Tilesets?

    - by Iscariot
    I have been scouring the internet for free tilesets that are open to you. I have found http://lostgarden.com/ It does not seem very useful. There are a few things here and there, but overall not much to really make a game off of. http://www.flyingyogi.com/fun/spritelib.html Spritelib is a little better it has some useful information, but is still the graphics are more in the 8bit variety. http://reinerstileset.4players.de/ This is heavily stylized and its hard to have this match with any other free tile-sets available. All other sites I have found have just been rips from games and those are protected by a copyright and remain unusable. Right now I need simple objects to build the inside of buildings, but I have seem to have come up short in that area. I have plenty of things for outside of buildings, but nothing for in. I am hoping someone else has had this problem and has found a solution. If not, I hope the information I have provided can help someone else in their conquest.

  • why does django-registration use an "activation window" for activating accounts?

    - by bharal
    i'm using django-registration, which is a django lib that helps with users registering on a django-built website. All well and dandy, except that it insists i have an "activation email" associated with all new users. It defaults to a 7 day window, after which, if someone signed up (and we then sent an email to confirm their email address) but didn't click on the link in the sent email within the 7 days, then they cannot sign up. Instead, they need to do the whole process all over again. I'm sure this is a concept that exists generally in web design, because why would django-registration make its own arbitrary signup process up? Anyway, the question is why? What do i gain by having the peace of mind knowing that all the users of my site are the kind of go-getters that click on registration emails with 7 days of receiving them? Why should i sleep easier knowing that my database isn't filled with users who, for whatever reason, clicked through to sign up but didn't actually want to sign up? cheers!

  • The Wheel Invention - Beneficial For Learning?

    - by Sarfraz
    Hello, Chris Coyier of css-tricks.com has written a good article titled Regarding Wheel Invention. In a paragraph he says: On the “reinventing” side, you benefit from complete control and learning from the process. And on the very next line he says: On the other side, you benefit from speed, reliability, and familiarity. Also often at odds are time spent and cost. He is right in both statements I think. I really like his first statement. I do actually sometimes re-invent the wheel to learn more and gain complete control over what I am inventing. I wonder why people are so much against that or rather biased. Isn't there the benefit of learning and getting complete control or probably some other benefits too. I would love to see what you have to say about this.

  • Calculating the angle between two points

    - by kingrichard2005
    I'm currently developing a simple 2D game for Android. I have a stationary object that's situated in the center of the screen and I'm trying to get that object to rotate and point to the area on the screen that the user touches. I have the constant coordinates that represent the center of the screen and I can get the coordinates of the point that the user taps on. I'm using the formula outlined in this forum: How to get angle between two points? -It says as follows "If you want the the angle between the line defined by these two points and the horizontal axis: double angle = atan2(y2 - y1, x2 - x1) * 180 / PI;". -I implemented this, but I think the fact the I'm working in screen coordinates is causing a miscalculation, since the Y-coordinate is reversed. I'm not sure if this is the right way to go about it, any other thoughts or suggestions are appreciated.

  • What is the standard way of using a sitemap with pages that require specific information passed to t

    - by Mike
    Hi, I have a website for which many pages rely on information passed to them (usually in the form of a querystring) or on a session variable. When making a web application, how do you normally handle these particular pages in regards to the sitemap? If you're using the standard ASP.NET menu control, it will render the node on the menu and if you click it, you could get an exception stating that a session variable doesn't exist (if it hasn't been created yet). For example, if you're making a user management area: All of these nodes get rendered, but I don't want the user to click on edit user or delete user without specifying someone to edit or delete. Any tips or suggestions would be greatly appreciated.

  • How do you plan for starting a new web system?

    - by Kerry
    I've been creating more and more systems recently and I find more and more planning and preparation I do before starting the project. I determine what libraries or frameworks I will be using, what languages, the basic architecture of how the site will flow, etc. I've also heard of other design processes such as hanging styrofoam balls to show where classes are and how they relate, which is a process I've never heard of nor do I know how it works. Is there any software that helps with this process? Are there any guidelines or steps or do you have a recommended set of steps or guidelines that you follow when designing a new project?

  • Java EE and JDK

    - by user269799
    I want to move from Java SE to Java EE. I will be using some of the sample projects that come with the Java EE. I have uninstalled the JDK but I think this may have been a mistake? When I download the latest Java EE (6), upon installation it asks me for the location of the JDK (which is uninstalled). I was under the impression that the JDK was specific to each version of Java i.e. SE or EE. Am I wrong here? I would have thought that when I download Java EE 6 that it was actually the EE JDK? Can anybody please clarify this for me? GF

  • When asked "How do I make a website?" how do you answer?

    - by Luke CK
    A (non-technical) friend of mine has asked me how to make a website. I get this question all the time. After a few questions I found out that she has an idea that could turn into a commercial site. I described three options to her: a) Get a book/enroll in a class/follow some online tutorials and learn how to do it. She's pretty smart and her personality seems like a good match for this sort of thing so I'm sure she could learn but she doesn't have a lot of time spare. Maybe if she started with one of those WYSIWYG editors at first? I stressed that this would take a longer than a couple of weekends of playing around. b) Hire someone to build it. Ranges from ultra cheap to ultra expensive, crappy to good and everything in between. I didn't mention sites like Rentacoder because she hasn't worked on a project like this before and doesn't know what to ask for. At this stage she'd likely ask for a Youtube-MySpace-Google for a few hundred bucks because she doesn't yet understand just how much is involved. c) Find someone technical and partner up with them. I explained that this can either work really well or be a disaster because she'd have to give up some of her ownership of the idea. How do you respond in these situations?
