  • jQuery attach function to 'load' event of an element

    - by Miguel Ping
    Hi, I want to attach a function to a jQuery element that fires whenever the element is added to the page. I've tried the following, but it didn't work: var el = jQuery('<h1>HI HI HI</H1>'); el.one('load', function(e) { window.alert('loaded'); }); jQuery('body').append(el); What I really want to do is to guarantee that another jQuery function that is expecting some #id to be at the page don't fail, so I want to call that function whenever my element is loaded in the page. To clarify, I am passing the el element to another library (in this case it's a movie player but it could be anything else) and I want to know when the el element is being added to the page, whether its my movie player code that it is adding the element or anyting else.

  • jQuery e.target bubbling best practice ?

    - by olouv
    In my heavy-ajax code, i always bind "click" the body tag & act depending on $(e.target) & using $.fn.hasClass(). However when i click on an anchor that has a </span> tag inside, my $(e.target) equals this node, and not the parent anchor as i would like it to. From now on, i have used this trick (var $t = $(e.target);) : /** bubbling **/ if($t.get(0).tagName !== "A" && $t.get(0).tagName !== "AREA") { $t = $t.parent("a"); if(empty($t)) return true; //else console.log("$t.bubble()", $t); } It feels wrong somehow... Do you have any better implementation ? $.fn.live() does not solve my issue as it still returns the span as the target. Moreover i'm looking for speed (running on atom-based touch devices) & live appeared to be way slower (twice) : http://jsperf.com/bind-vs-click/3 In fact, as @Guffa pointed, using $.fn.live() solves the span bubbling issue as i don't need the event.target anymore. I guess there is no other "right" answer here (using bind).

  • jQuery click event to make a div slide down and push next div out of viewport

    - by Josh
    I'm trying to figure out how to make jQuery slide #content2 down and replace content1 with it while making it look like #content1 is actually being pushed down by #content1 removing it from view... Then the same button that was clicked to make #content2 replace #content1 would also need to do the reverse effect by replacing #content2 with #content1 making them slide up and push each other out of the way... I'm not all that great with jQuery so I'm sure I've gone about this the wrong way, but here's what I've tried: $(document).ready(function() { $('#click').click(function() { if($('#content1').is(':visible')) { $('#content1').slideUp(); } else { $('#content2').slideDown(); } }).click(function() { if($('#content1').is(':visible')) { $('#content2').slideDown(); } else { $('#content1').slideUp(); } }); });

  • Analyze log files from many languages using a single tool. And recommendations of logging frameworks

    - by Binary255
    We have a system build on lots of languages. The ones we are interested in logging, in order of priority, are: C/C++ PHP C# Bash Java Wish list: If it is possible, we would like logging to be achieved from the above languages in such a way that we may use a single log viewing tool for all of them. Ideally they would be in the same format, but next to that in as few formats as possible and readable from as many log file viewers as possible. If it is possible logging to a single log file or a set of log files would be nice. With a possibility to filter based on the source language that is being logged. We would like to copy the log files (or should be log to a database and copy it instead?) from multiple servers to a single location. So that we can analyze the log files from many servers at the same time (to see if any of our servers execute a certain piece legacy code for example). Being able to change logging level at runtime would be nice. Thank you for reading! It's quite a complex problem, I hope someone has wrestled with it before and has some valuable information!

  • PHP/MySQL - Working with two databases, one shared and one local to an instance of application

    - by Extrakun
    The situation: Using a off-the-shelf PHP application, I have to add in a new module for extra functionality. Today, it is made known that eventually four different instances of the application are to be deployed, but the data from the new functionality is to be shared among those 4 instances. Each instance should still have their own database for users, content and etc. So the data for the new functionality goes into a 'shared' database. The data for the application (user login, content, uploads) go into a 'local' database To make things more complex, the new module I am writing will fetch data from the local DB and the shared DB at the same time. A re-write of the base application will take too long. I only have control over the new module which I am writing. The ideal solution: Is there a way to encapsulate 2 databases into one name using MySQL? I do not wish to switch DB connections or specifically name the DB to query from inside my SQL statements. The application uses a DB wrapper, so I am able to change it somehow so I can invisibly attempt to read/write to two different DB. What is the best way to handle this problem?

    - by chrsk
    What happens if #setDefault(TimeZone timezone) is called by a concurrent application running on the same application server with JDK 1.6 As discussed in TimeZone #setDefault changes in JDK 6 the call now changes VM wide, this can have horrible consequences. If you're not adminsitrating the application server, how to ensure TimeZone doesn't change?

  • Powershell profile "on exit" event?

    - by poke
    I'm looking for a way to automatically do some clean up tasks when the PowerShell session quits. So for example in my profile file I start a process which needs to run in the background for quite a lot of tasks and I would like to automatically close that process when I close the console. Is there some function the PowerShell automatically calls when closing the session as it does with prompt when displaying the prompt?

  • .Net framework 1.1 web application on Safari

    - by Vijay
    We have an intranet web application developed using .NET framework 1.1 The application has few validators and fired from the server side (They are not client side validators). The web application runs perfectly fine on IE and Firefox (both on Mac and Windows). However on Safari(ver 4.0.3) browser running on Mac, the application intermittently fails to do post-back while submitting the page and just reloads the page. Is this issue something to do with .Net framework 1.1 or Safari browser? Is there any way to resolve this issue? Any pointers on this would be very helpful. Thanks!

  • ImageButton OnClick Event not firing

    - by webnoob
    Hi All, I am really confused about this one. I have some code that runs fine on my development server but I am now trying to get the site working on the sales guys new laptop. None of the image buttons on the website seem to be working for him (they just redirect me back to the websites homepage) whereas they used to on his previous machine. The only difference between each machine is that his old one was Vista and the new one is Windows 7. Has anyone come accross this issue? Some code: The form: <div class="form_text"></div> <div class="form_box_link"> <asp:ImageButton id="LoginSubmitButton" onClick="FLoginWebService" ImageURL="~/Images/login.png" runat="server" /> </div> The code behind (delphi): procedure TMemberLogin.FLoginWebService(Sender: TObject; e: System.EventArgs); begin //Code Removed but using OutputDebugString shows nothing is being done in here end; As mentioned, this works everywhere else except on his windows 7 machine.

  • Invalidating session before iPhone application quits

    - by tartox
    Hello I would like to tell the server to invalidate an ongoing session when the user quits the iPhone application. In the app delegate, I send a request to the server in the (void)applicationWillTerminate:(UIApplication *)application method. I am not waiting for a server answer, I just want to send the request and quit. However I cant see any packet leaving the application. The same code in another place works fine. Session has a limited duration anyway and the server will invalidate it after a while, but I would prefer to do it nicely when leaving application. Is it normal that no NSURLConnection can be established from the applicationWillTerminate method ? Thank you.

  • Setting Class-Level Variable to Use Between Event Handlers

    - by lush
    I'm having a hard time understanding why the following code doesn't work. I'm sure it's something remedial that I'm missing or not understanding. I currently have a page that asks for user input. If, based on the input and logged in user, I find data from this page already in the database, I need to update the existing records rather than creating new ones, so I set a class-level bool to true. The problem is, when MyNextButton is clicked, PreviouslySubmitted is still false. So, I'm not sure how to make the value of this variable persist. Any advice is appreciated, thanks. public partial class MyForm : System.Web.UI.Page { private bool previouslySubmitted; protected void Page_Load(object sender, EventArgs e) { MyButton.Click += (o, i) => { q = from a in db.TableA where (a.SomeField == SomeValue) select a; if(q.Any()) { PreviouslySubmitted = true; //populate the form's fields with values from database for user to revise } } MyNextButton.Click += (o, i) => { if(PreviouslySubmitted) { //update database } else { //insert into database } }

  • Application.ProcessMessages hangs???

    - by X-Ray
    my single threaded delphi 2009 app (not quite yet complete) has started to have a problem with Application.ProcessMessages hanging. my app has a TTimer object that fires every 100 ms to poll an external device. i use Application.ProcessMessages to update the screen when something changes so the app is still responsive. one of these was in a grid OnMouseDown event. in there, it had an Application.ProcessMessages that essentially hung. removing that was no problem except that i soon discovered another Application.ProcessMessages that was also blocking. i think what may be happening to me is that the TTimer is--in the app mode i'm currently debugging--probably taking too long to complete. i have prevented the TTimer.OnTimer event hander from re-entering the same code (see below): procedure TfrmMeas.tmrCheckTimer(Sender: TObject); begin if m_CheckTimerBusy then exit; m_CheckTimerBusy:=true; try PollForAndShowMeasurements; finally m_CheckTimerBusy:=false; end; end; what places would it be a bad practice to call Application.ProcessMessages? OnPaint routines springs to mind as something that wouldn't make sense. any general recommendations? i am surprised to see this kind of problem arise at this point in the development!

    Hello! I'm trying to convert my MFC application, a simple "PaintBrush" app that draws lines and rectangles (it's only a little test from another bigger application), to a ActiveX Control that a could embed into a Windows Forms Application (with Visual C#). I didn't found any tutorial for do this, and now, I'm not sure that this it's possible. I know how create an ActiveX Control recently created but not how convert an existing application. Have anybody know how I can do this? Thanks!

  • Websphere Java application startup

    - by Tom Barnett
    I have two Java applications running on a Websphere application server. The first application is COTS software (Plateau) I will call App1 and includes an API which can be used in custom applications to interact with App1. This app takes a couple minutes to start in Websphere. The second application is custom software I will call App2 and is deployed as a web service which utilizes the App1 API to interact with App1; so it is dependent on App1. This app takes just seconds to start in Websphere. I run into a problem in certain App1 functionality when we bounce Websphere and the App2 web service is called by a client before the App1 application has fully started. Is there a way I can delay App2 from starting until App1 is fully started in Websphere? Is there a way to design App2 to programmatically check that App1 is available before it attempts to use the API?

  • iPhone Application Deploy without using iTunes

    - by Paulo Correia
    I want to build an application for the iPhone to be used inside a customer enterprise (very small, only 5 to 10 devices). But since they will be paying the application development, I don't want to distribute that application to the world inside the App Store in iTunes. How can I distribute this app to my customer? Should I get the Enterprise level subscription from the Apple Developer Program? Since I work as a freelancer, I think I can't subscribe to that program.

  • Reference the oncomplete event by an external java script function

    - by user339637
    Hi , I want to do some logic at the oncomplete attribute of the a4j:commandButton ,but my logic is too complicated , can I reference the code using a java script functions located in a external java-script file to have a better maintenance ? I found it has error because the JavaScript file cannot understand the EL expression . For example , originally I have , <a4j:commandButton id="btn1" action="#{MBena1.action1}" oncomplete="if( {MBena1.variable1}){Richfaces.showModalPanel('modelPanel1');};if (......) then "> I want to do something like this: <a4j:commandButton action="#{MBena1.action1}" oncomplete="Btn1OnComplete();"> the code is put inside the java script function Btn1OnComplete() which is located in a external java-script file. Thanks

  • DWR and other possible tools for build java application level Ajax framework

    - by Fazal
    I would assume that this question would have been asked in different ways already, but I could not find one so posting it. Sorry if its a repetition The basic idea which I am trying to explore is to design a common Ajax framework/API for our application. The main requirement is to have a common framework in the product which every module in the application can call whenever it needs to provide Ajax behavior. We basically have a page based application and not everything would be Ajax for sure. Mostly it will be smaller pieces of work which Ajax will handle. We have used GWT and it works great. But we have some constraints because of which certain areas in the application need to build standard jsp and html pages only I know little bit about dwr and it looks very promising (as even answered by some people). I wanted to know what are the other possible frameworks like dwr which I can evaluate too, before making the decision

  • Extraction Event

    - by Anicho
    So I have the following code: public override void Extract(object sender, ExtractionEventArgs e) { if (e.Response.HtmlDocument != null) { var myParam = e.Request.QueryStringParameters.Where(parameter => parameter.Name == QueryName).Select(parameter => parameter.Value).Distinct(); myParam. // add the extracted value to the web performance test context e.WebTest.Context.Add(this.ContextParameterName, myParam.ToString()); e.Success = true; return; } // If the extraction fails, set the error text that the user sees e.Success = false; e.Message = String.Format(CultureInfo.CurrentCulture, "Not Found: {0}", QueryName); } It's returning: System.Linq.Enumerable+<DistinctItem>d_81`1[system.string] I am expecting something along the lines of: 0152-1231-1231-123d My question is how do I extract the querystring's actual value from extractioneventargs. They say it's possible, but I have no idea.

  • How best to associate code with events in jQuery?

    - by Ned Batchelder
    Suppose I have a <select> element on my HTML page, and I want to run some Javascript when the selection is changed. I'm using jQuery. I have two ways to associate the code with the element. Method 1: jQuery .change() <select id='the_select'> <option value='opt1'>One</option> <option value='opt2'>Two</option> </select> <script> $('#the_select').change(function() { alert('Changed!'); }); </script> Method 2: onChange attribute <select id='the_select' onchange='selectChanged();'> <option value='opt1'>One</option> <option value='opt2'>Two</option> </select> <script> function selectChanged() { alert('Changed!'); } </script> I understand the different modularity here: for example, method 1 keeps code references out of the HTML, but method 2 doesn't need to mention HTML ids in the code. What I don't understand is: are there operational differences between these two that would make me prefer one over the other? For example, are there edge-case browsers where one of these works and the other doesn't? Is the integration with jQuery better for either? Does the late-binding of the code to the event make a difference in the behavior of the page? Which do you pick and why?

  • jQuery TriggerHandler doesn't trigger keyup event set via live

    - by Beck
    Why i can't trigget handler via triggerHandler if it's was bound via live? For example form.find('#code').live('change keyup',function(){ process_code($(this)); }); Startups after window load: /* Triggers */ if(checkCookie('banner_ready_code')) { $('#form').find('#code').triggerHandler('keyup'); } Nothing happens... If i'm binding simply by .change or .keyup, triggerHandler is working properly as intended. If it's bug, where to report it. Too lazy :) If not, please explain. :)

  • Can't reach custom C# forms application remotely.

    Hello, I'm working in Windows Server 2008. I have a very basic C# forms application (not a service) that is listening on a port, say 56112. When using telnet I can connect from the localhost and send and receive data. For some reason I cannot remotely connect to the application. I know I have a connection because I can telnet to 23 on the remotely fine. I've opened this port on the firewall, created rules in/out in advanced firewall, disabled the firewall completely, and more. Any suggestions would be great! This is the telnet output: Microsoft Telnet> open server.cc 56112 Connecting server.cc...Could not open connection to the host, on port 56112: Connect failed
