  • Website. AJAX and FIREFOX problems. I dont think Firefox likes ajax..?

    - by DJDonaL3000
    Working on an AJAX website (HTML,CSS,JavaScript, AJAX, PHP, MySQL). I have multiple javascript functions which take rows from mysql, wrap them in html tags, and embed them in the HTML (the usual usage of AJAX). THE PROBLEM: Everything is working perfect, except when I run the site with Firefox (for once its not InternetExplorer causing the trouble). The site is currently in the developmental stage, so its offline, but running on the localhost (WampServer, apache, Windows XP SP3,VISTA,7). All other cross-browser conflicts have been removed, and works perfectly on all major browsers including IE, Chrome, Opera and Safari, but I get absolutely nothing from the HTTPRequest (AJAX) if the browser is Firefox. All browsers have the latest versions. THE CODE: I have a series of javascript functions, all of which are structured as follows: function getDatay(){ var a = document.getElementById( 'item' ).innerHTML; var ajaxRequest; try{//Browser Support Code: // code for IE7+, Firefox, Chrome, Opera, Safari: ajaxRequest = new XMLHttpRequest(); } catch (e){ // code for IE6, IE5: try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser is not compatible - Browser Incompatibility Issue."); return false; } } } // Create a function that will receive data sent from the server ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState < 4){ document.getElementById( 'theDiv' ).innerHTML = 'LOADING...'; } if(ajaxRequest.readyState == 4){ document.getElementById( 'theDiv' ).innerHTML = ajaxRequest.responseText; } } //Post vars to PHP Script and wait for response: var url="01_retrieve_data_7.php"; url=url+"?a="+a; ajaxRequest.open("POST", url, false);//must be false here to wait for ajaxRequest to complete. ajaxRequest.send(null); } My money is on the final five lines of code being the cause of the problem. Any suggestions how to get Firefox and AJAX working together are most welcome...

  • What are best practices for securing the admin section of a website?

    - by UpTheCreek
    I'd like to know what people consider best practice for securing the Admin sections of websites, specifically from an authentication/access point of view. Of course there are obvious things, such as using SSL and logging all access, but I'm wondering just where above these basic steps people consider the bar to be set. For example: Are you just relying on the same authentication mechanism that you use for normal users? If not, what? Are you running the Admin section in the same 'application domain'? What steps do you take to make the admin section undiscovered? (or do you reject the while 'obscurity' thing)

  • amazon design doubt

    - by praveen
    I was looking at the amazon website and was wondering how one of the feature would have been implemented. The feature : what customers buy after viewing a particular item. If i were to develop such a feature i would probably generate a session id for each user session and store the session id-page id combination in a log file. and if a book is bought set a separate flag for the session id-page id. A separate program can then be run on the log file periodically, to identify the groups that were bought together/viewed together and that information can be stored in a persistent file. This is ofcourse a simple solution without taking into consideration the distributed nature of the servers - but would this suffice or can you help me identify a better design.

  • Practical ways around the GPL?

    - by Daniel
    My company makes an extremely specialized piece of software which costs a lot of money for those few who need it. On our current release we have no choice but to use a few libraries which are released only under the GPL. Releasing the code is not an option and it would take months, if not years to implement the functionality the libraries provide. What do companies do in this situation? Are there practical and legal ways around the GPL?

  • Do you take the pain of learning it or use an out of the box solution?

    - by Mantorok
    Hi all What I'm getting at here is being presented with a control or framework that does 95% of what you want but has its shortcomings when opposed to learning how to do it yourself. To give a good example (ASP.Net) UpdatePanel vs DIY JS/JSON. The UpdatePanel gives you AJAX instantly without doing anything additional, however I've come to learn that its shortcomings are mainly that it's a bit of a hack and performs badly on busy pages and I've found myself having to scrap UpdatePanels in favour of rolling my own JS, and I've now made it a habit to fully investigate any shortcomings in out-of-the-box solutions, as I've been stung by this experience. So I guess what I'm asking is: Is it better to find out how to DIY or is it considered a better approach to try the available solution and risk going a full circle? Obviously I've only targetted a single control, but it is a very attractive control to people learning AJAX - I'm sure there are others out there. Sorry if dupliate. Thanks

  • What does Silverlight offer?

    - by Maurizio Reginelli
    I'm working with C# and WPF and I would like to study something related to web programming. I already know HTML and CSS, and since I'm working with WPF, I am wondering if going into Silverlight is a good choice to start web developing. Can it be a substitute of server-side programming languages, like PHP or ASP .NET? What do you suggest? Thank you very much

  • Question about the evolution of interaction paradigm between web server program and content provider program?

    - by smwikipedia
    Hi experts, In my opinion, web server is responsible to deliver content to client. If it is static content like pictures and static html document, web server just deliver them as bitstream directly. If it is some dynamic content that is generated during processing client's request, the web server will not generate the conetnt itself but call some external proram to genearte the content. AFAIK, this kind of dynamice content generation technologies include the following: CGI ISAPI ... And from here, I noticed that: ...In IIS 7, modules replace ISAPI filters... Is there any others? Could anyone help me complete the above list and elabrate on or show some links to their evolution? I think it would be very helpful to understand application such as IIS, TomCat, and Apache. I once wrote a small CGI program, and though it serves as a content generator, it is still nothing but a normal standalone program. I call it normal because the CGI program has a main() entry point. But with the recenetly technology like ASP.NET, I am not writing complete program, but only some class library. Why does such radical change happens? Many thanks.

  • Using Action Filters for user login in Asp.NET MVC?

    - by ripper234
    I recently built a site using Asp.Net. The way I chose to implement user login is through a base 'UserAwareController' class, that all controllers extend. It contained a reference to the UserRepository, and exposed a protected GetCurrentUser() method that concrete controllers could query. The whole process felt a bit wishy-washy to me. Is Action Filters a good alternative? What are its benefits? Is there something else I might be missing?

  • How could I apply a genetic algorithm to a simple game that follows rollercoaster tracks?

    - by Chris
    I have free-rein over what I do on a final assignment for school, with respect to modifying a simple direct-x game that currently just has the camera follow some rollercoaster rails. I've developed an interest in genetic algorithms and would like to take this opportunity to apply one and learn something about them. However, I can't think of any way I could possibly apply one in this case. What are some options available to me?

  • How to reset all the values after completion of the game, before starting it again ?

    - by srikanth rongali
    I have writing a small shooting game in cocos2d. Winning the game is to eliminate all the 10 enemies. After that end screen comes showing 'You Won' and 'Play Again'. If I go for 'Play Again' option the game is starting from where I need. But, the problem is that the game is continuing from previously ended state. I mean it is not starting from enemy 1 again instead it is just showing the end of 10 enemy. I think I have to reset all the values before pushing the scene. But should I reset all the values I have used or there is any other way ? Thank You.

  • How to extract delegates from ViewController class?

    - by adranle
    Hi I have the problem that my view controller class has too many delegates and starts to get big. I want to write the delegates in separate classes to keep the view controller class small. For delegates that are programmatically created (like UIAlertViewDelegate) I could do it easily. The problem is in the delegates assigned in Interface Builder. How can I tell the IB to assign, for example, another class as the UITableViewDelegate or UITableViewDataSource? Or how to choose another IBAction method for a Touch UP inside Event on a button? One solution would be to delete the connections from IB and write them programmatically at ViewDidLoad, but since I have a lot of ViewControllers, this would take a long time. any other ideas?

  • Which Java web frameworks provide hot-reload?

    - by Stefane Fermigier
    I'd like to know which Java web application frameworks do provide a "hot reload" capability, i.e. allow to develop applications and have them redeployed on the server "almost instantly" (i.e. in less than a few seconds). I the Java world, Play! has it out of the box, but what I'm looking for is a more exhaustive list. Other examples that I'm aware of include: Nuxeo WebEngine, provided you're using Eclipse and the right plugin, or, in the Python world, Django and Pylons (when using the "--reload" option).

  • Using AJAX to display error message Ruby on Rails

    - by bgadoci
    I have built a blog using Ruby on Rails. New to both. I am implementing AJAX pretty effectively until I get to the error handling portion. I allow for comments on posts and do this by rendering a comment partial and remote form in the /views/posts/show.html.erb page. Upon successful save of a comment the show page is updated using views/comments/create.js.rjs and displays a flash notice. I am simply trying to flash a notice when it doesn't save. Searched around and worked this a bit on my own. Can't get it to fly. Here is my code: /views/posts/show.html.erb <div id="comments"> <%= render :partial => @post.comments %> <div id="notice"><%= flash[:notice] %></div> </div> <% remote_form_for [@post, Comment.new] do |f| %> <p> <%= f.label :body, "New Comment" %><br/> <%= f.text_area (:body, :class => "textarea") %> </p> <p> <%= f.label :name, "Name" %><br/> <%= f.text_field (:name, :class => "textfield") %> </p> <p> <%= f.label :email, "Email" %><br/> <%= f.text_field (:email, :class => "textfield") %> </p> <p><%= f.submit "Add Comment" %></p> <% end %> /views/comments/_comment.html.erb <% div_for comment do %> <div id="comment-wrapper"> <% if admin? %> <div id="comment-destroy"><%=link_to_remote "X", :url => [@post, comment], :method => :delete %></div> <% end %> <%= h(comment.body) %><br/><br/> <div class="small">Posted <%= time_ago_in_words(comment.created_at) %> ago by <%= h(comment.name) %> <% if admin? %> | <%= h(comment.email) %> <% end %></div> </div> <% end %> /views/comments/create.js.rjs page.insert_html :bottom, :comments, :partial => @comment page[@comment].visual_effect :highlight page[:new_comment].reset page.replace_html :notice, flash[:notice] flash.discard CommentsController#create def create @post = Post.find(params[:post_id]) @comment = @post.comments.create!(params[:comment]) respond_to do |format| if @comment.save flash[:notice] = "Thanks for adding this comment" format.html { redirect_to @post } format.js else flash[:notice] = "Make sure you include your name and a valid email address" format.html { redirect_to @post } format.js end end end

  • ASP.NET MVC Actions that return different views, or just make a ton of Actions?

    - by Nate Bross
    So, I am in a situation, where I need to display a different view based on the "Role" that the authenticated user has. I'm wondering which approach is best here: [Authorize(Roles="Admin")] public ActionResult AdminList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } [Authorize(Roles = "Consultant")] public ActionResult ConsultantList(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); return View(data); } or should I do something like this [Authorize] public ActionResult List(int? divID, int? subDivID) { var data = GetListItems(divID.Value, subDivID.Value); if(HttpContenxt.User.IsInRole("Admin") { return View("AdminList", data ); } if(HttpContenxt.User.IsInRole("Consultant") { return View("ConsultantList", data ); } return View("NotFound"); }

  • When to databind data-bound controls?

    - by sanjuro
    Hi, i have little dilemma, i often use data-bound controls such as Gridview in conjunction with ObjectDataSource. But i have two possible options when can i bind data to Gridview. The first is that i set datasourceid of gridview in aspx file and databind occurs in a moment before PreRender event occurs or i can set datasource in Page_Load event and databinding occurs immediately, something like this: protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { testGridView.DataSource = testObjectDataSource.Select(); testGridView.DataBind(); } } I think that in second approach i have more control above databinding. But how it is in real programming life? Which of the above two options is commonly used? Or is there some third option how can i bind data to data-bound control? Thanks for your opinions from real-life experiences.

  • What are the benefits of learning a new language, as a game developer?

    - by Keand64
    I'm an independant game developer/designer, and I'm wondering what specific benefits are there to learning a new programming language. I do my programming in C++ currently, and I want to know if there are any tangible benefits to learning a different language, as in, benefits to writing a game x in language y versus game w in language z? Basically, I understand that learning a new programming language will help me think about a problem in different ways, but what are some actual benefits to using one language over another in specific scenarios?
