    - by haltman
    Hi everybay! I use an object to check that a group of radio buttons have a precise value like set on "rule" object.

  • Is there a jQuery widget equal to DOJO's TitlePane?

    - by Bill Caswell
    I like the visual behavior of the DOJO TitlePane widget, but it has too much other bunk for my purpose. http://dojotoolkit.org/reference-guide/dijit/TitlePane.html#dijit-titlepane Is anyone aware of a jQuery widget that provides the same ability to expose and hide content in a stacked manner with the little flippy-arrow, pane highlighting on mouse over, etc? An accordion does not accomplish my goal being able to have multiple panes open at the same time. Thanks in advance.

  • How to stop listening on an HTTP::Daemon port in Perl

    - by Trevor
    I have a basic perl HTTP server using HTTP::Daemon. When I stop and start the script, it appears that the port is still being listened on and I get an error message saying that my HTTP::Daemon instance is undefined. If I try to start the script about a minute after it has stopped, it works fine and can bind to the port again. Is there any way to stop listening on the port when the program terminates instead of having to wait for it to timeout? use HTTP::Daemon; use HTTP::Status; my $d = new HTTP::Daemon(LocalAddr => 'localhost', LocalPort => 8000); while (my $c = $d->accept) { while (my $r = $c->get_request) { $c->send_error(RC_FORBIDDEN) } $c->close; undef($c); }

  • C# CodeDom - making project's forms accessible for scripts.

    - by michal
    Hi, I'm learning CodeDom scripting, I started with http://www.c-sharpcorner.com/uploadfile/mgold/codedomcalculator08082005003253am/codedomcalculator.aspx Now I'd like to allow script modify the project's form (for learning purposes only). I suppose I need to create new field for a class I'm generating which refers "this". However I have no idea how can I set a reference for script-accessible object ... ? Or can I directly publish some class member (like "this" or "button1") to a CodeDom script structure?

  • jQuery $.data(): Possible misuse?

    - by Rosarch
    Perhaps I'm using $.data incorrectly. Assigning the data: var course_li = sprintf('<li class="draggable course">%s</li>', course["fields"]["name"]); $(course_li).data('pk', course['pk']); alert(course['pk']); // shows a correct value Moving the li to a different ul: function moveToTerm(item, term) { item.fadeOut(function() { item.appendTo(term).fadeIn(); }); } Trying to access the data later: $.each($(term).children(".course"), function(index, course) { var pk = $(course).data('pk'); // pk is undefined courses.push(pk); }); What am I doing wrong? I have confirmed that the course li on which I am setting the data is the same as the one on which I am looking for it. (Unless I'm messing that up by calling appendTo() on it?)

  • Why doesn't splicing an object from an array in Javascript return the array?

    - by Allen Gould
    I have an array of objects (say, a deck of cards): var deck = []; deck.push(new Card(suit, rank)); The following seems to work: var card = deck.pop(); var card = deck.shift(); (pulling from the "top" or "bottom" of the deck respectively) But if I want a card from the middle (say, if this was a hand of cards) var card = deck.splice(2,1); The object doesn't seem to get properly assigned to the variable (everything is undefined). Everything I look up says that splice should return the object that I'm removing - what am I missing?

  • Variable scope problem in JavaScript

    - by dfjhdfjhdf
    I declare a variable with the var word inside a function that handles Ajax requests, then later on in the function I have another function that should change the value of the variable but - my problem - it fails. How to settle the problem down? Here's similiar code I use: function sendRuest(someargums) { /* some code */ var the_variable; /* some code */ //here's that other function request.onreadystatechange = function() { if (request.readyState == 4) { switch (request.status) { case 200: //here the variable should be changed the_variable = request.responseXML; /* a lot of code */ //somewhere here the function closes } return the_variable; } var data = sendRequest(someargums); //and trying to read the data I get the undefined value

  • YAHOO.util.Connect.asyncRequest does not work in Safari

    - by 24x7Programmer
    When I request a webpage using YAHOO.util.Connect.asyncRequest in Safari I always get Communication Failure message in callback's failure properties statusText. The same method works in IE. What could be wrong here? Here is the code. When the code is executed I always get two alerts: "Three" and "communications failure undefined" (corresponding to the second alert in the failure part below.) Also when I attach the debugger and put break point in the SAProvision.aspx's page load event, the break point is not hit. So it is sure that in safari the page is not being called. While the same is called when executed from IE. function ProvisionBlade() { var path = "http://localhost/SC/Dashboard/SAProvision.aspx" YAHOO.util.Connect.asyncRequest("POST", path, callbacks1, null); } var callbacks1 = { success: function(o) { var check = "test"; alert(o.responseText); }, failure: function(o) { alert("Three"); alert(o.statusText + ' ' + o.responseText); } }

  • No-argument method on window.external is invoked when checking with typeof

    - by janko
    Hi, I am trying to display an HTML page with embedded JavaScript code inside a System.Windows.Forms.WebBrowser control. The JavaScript code is expected to interact with the embedding environment through the window.external object. Before invoking a method on window.external, JavaScript is supposed to check for the existance of the method. If it is not there, the code should invoke a generic fallback method. // basic idea if (typeof(window.external.MyMethod) != 'undefined') { window.external.MyMethod(args); } else { window.external.Generic("MyMethod", args); } However, checking for a no-argument method with typeof seems to invoke the method already. That is, if MyMethod accepts any positive number of arguments, the code above will work perfectly; but, if MyMethod is a no-argument method, then the expression typeof(window.external.MyMethod) will not check for its type but invoke it, too. Is there any work-around to this behavior? Can I somehow escape the expression window.external.MyMethod to prevent the method call from occurring?

  • Function declaration in C and C++

    - by Happy Mittal
    I have two C++ files, say file1.cpp and file2.cpp as //file1.cpp #include<cstdio> void fun(int i) { printf("%d\n",i); } //file2.cpp void fun(double); int main() { fun(5); } When I compile them and link them as c++ files, I get an error "undefined reference to fun(double)". But when I do this as C files, I don't get error and 0 is printed instead of 5. Please explain the reason. Moreover I want to ask whether we need to declare a function before defining it because I haven't declared it in file1.cpp but no error comes in compilation.

    Our WCF svc files contain the following: <%@ ServiceHost Service="Foo" Factory="Bar" Language="C#" Debug="true" %> What does debug=true mean in this case? web.config has debug=false, but I don't know what this one means and can't find a reference on MSDN.

  • Align 2 sets of 2D point clouds

    - by user108088
    From what I gather, there are two major methods to perform alignment on point clouds, Iterative Closest Point (ICP) and Particle Filtering. What are the advantages of each method? And can someone point me some good tutorials. For what I am currently doing, I think ICP would be easier, I can't seem to find any simple reference implementations online for 2d point sets. Has anyone seen (psuedo)code for ICP with details on the transformation step? Thanks in advance.
