  • Jquery click behaviour

    - by VP
    I'm developing a menu. This menu, will change the background image when you click on a link, as almost all menus does. if i click in one link from the menu, this link backgroun will change the color. My jquery script is: $(function() { $('#menu ul li').click(function() { $('#menu ul li').removeClass("current_page_item"); $(this).addClass("current_page_item"); //return false; }); }); today, with the "return false" commented, when i click on the link under "#menu ul li" it changes the background open the new page and the background is reseted. For sure, if i uncomment the return false, the background works fine but then i cannot open any link. So its looks like after that i open a new page, it reset the classes. How can i make it persistent?

  • Allowing threads from python after calling a blocking i/o code in a python extension generated using

    - by SS
    I have written a python extension wrapping an existing C++ library live555 (wrapping RTSP client interface to be specific) in SWIG. The extension works when it is operated in a single thread, but as soon as I call the event loop function of the library, python interpreter never gets the control back. So if I create a scheduled task using threading.Timer right before calling the event loop, that task never gets executed once event loop starts. To fix this issue, I added Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS macros manually in the SWIG auto generated wrapper cxx file around every doEventLoop() function call. But now, I want to do the same (i.e. allow threads) when SWIG generates the code itself and not to change any code manually. Has anyone done something similar in SWIG? P.S. - I would also consider switching to any other framework (like SIP) to get this working. I selected SWIG over any other technology is because writing SWIG interface was really very easy and I just had to include the existing header files.

  • jQuery $.post with PasteBin API

    - by John K
    Ok, I'm trying to use jQuery $.post with the PasteBin API to create a PasteBin page and grab the URL (which the API says it returns). Here is my code so far: $('#send_code').click(function(){ $.post('http://pastebin.com/api_public.php', { paste_name: $('#paste_name').val(), paste_code: $('#paste_code').val() }, function(data){ alert(data); }); } The above script creates the page just fine (I can find them on PasteBin). However, all that is returned is an empty string. I've tried using this same API with php and cURL, and I'm able to retrieve the URL just fine. Can anyone see if I'm doing something wrong? Thanks!

  • Needing forward declaration in Ruby

    - by dbarbosa
    Hi, I am trying to write a Ruby script in one file. I would like to know if it is possible to write the "main" function in the beginning, having the other functions that are used by main, defined after it. In other words, I would like to call a not yet defined function, so that they do not depends on definition order. Just changing the order is not possible because it gives an "undefined method" error. In C/C++ we use forward declarations... is there something similar in Ruby or another solution to this?

  • FxCop giving a warning on private constructor CA1823 and CA1053

    - by Luis Sánchez
    I have a class that looks like the following: Public Class Utilities Public Shared Function blah(userCode As String) As String 'doing some stuff End Function End Class I'm running FxCop 10 on it and it says: "Because type 'Utilities' contains only 'static' ( 'Shared' in Visual Basic) members, add a default private constructor to prevent the compiler from adding a default public constructor." Ok, you're right Mr. FxCop, I'll add a private constructor: Private Utilities() Now I'm having: "It appears that field 'Utilities.Utilities' is never used or is only ever assigned to. Use this field or remove it." Any ideas of what should I do to get rid of both warnings?

  • How to check for empty values on two fields then prompt user of error using javascript

    - by Matthew
    Hello guys, I hope I can explain this right I have two input fields that require a price to be entered into them in order for donation to go through and submit. The problem that I am having is that I would like the validation process check to see if one of the two fields has a value if so then proceed to submit. If both fields are empty then alert. This is what I have in place now: function validate_required(field,alerttxt) { with (field) { if (value==null||value=="") {alert(alerttxt);return false;} else {return true} } } function validate_form(thisform) { with (thisform) { if (validate_required(input1,"Need a donation amount to continue")==false) {input1.focus();return false;} else if (validate_required(input2,"Need a donation amount to continue")==false) {input2.focus();return false;} } } I would like to ultimately like to get this over to Jquery as well Thanks guys any help would do Matt

  • css transition initial value

    - by nizzle
    I would like to animate a div from right to left. I cannot use a stylesheet because I don't know the amount of px. If I set the initial value (where the animation starts from) and the end-value in the same function, it doesn't work. //DOES NOT WORK $("#hi").css({"width" : "200px", "transform" : "translateX(500px)"}); $("#hi").css({"transition" : "all 5s ease-out", "transform" : "translateX(0px)"}); //WORKS $("#alsohi").css({"width" : "200px", "transform" : "translateX(500px)"}); setTimeout(function(){ $("#alsohi").css({"transition" : "all 5s ease-out", "transform" : "translateX(0px)"}); }, 50); as you can see in this fiddle: http://jsfiddle.net/c66Fb/ what is a better solution to this than using a timeout?

  • Avoiding exceptions when uploading files in laravel

    - by occam98
    I've got a file upload field (attachment1) in a form that may or may not have a file uploaded in it when I process the form in laravel. When I'm trying to process the page, this line generates an exception: Input::upload('attachment1',path('storage').'attachments/'.$name); Here is the text of the exception: Message: Call to a member function move() on a non-object it seems that I need to check in advance to see if 'attachment1' has a file, and I found that the function Input::has_file('attachment1') is supposed to tell me whether or not 'attachment1' has a file, but even when I submit an empty form, it returns true. Also, from reading documentation, it seems that Input::upload is supposed to just return false when trying to upload a non-existant file, so why does it produce this exception instead, and how can I fix it?

  • Blinking an item. (Jquery FadeIn FadeOut ?)

    - by 0plus1
    I have two divs that I want to make blink at the same time until the user hovers the mouse on one of them. var shouldiblink = '1'; function mrBlinko(divid){ while (shouldiblink =='1') { $("#"+divid).fadeIn(100).fadeOut(300); } $(document).ready(function(){ mrBlinko("mydiv1"); mrBlinko("mydiv2"); } The I'll have an hover event that sets shouldiblink to '0'. Problem is that the loops starts as soon as the page is ready and the browser crashes. I'm stuck with this solution and I can't think of an alternative right now. Can you help me? Thank you very much.

  • average velocity, as3

    Hello, I need something accurate I can plug equations in to if you can help. How would you apply the equation bellow? Thanks guys. AVERAGE VELOCITY AND DISPLACEMENT average velocity V=X/T displacement x=v*T more info example I have 30 seconds and a field that is 170 yards.

  • GetDC() DllImport for x64 apps

    - by devdept
    If you make a little research on the internet you'll see many DLLImport styles for this user32.dll function: HDC GetDC(HWND hWnd); The question is: what type is more appropriate for .NET x64 apps (either compiled with the Platform target as AnyCPU on a x64 machine or specifically as x64)? IntPtr for example grows to a size of 8 on a x64 process, can this be a problem? Is uint more appropriate than Uint64? What is the size of the pointers this function uses when used in a x64 process? The DLL is called user32.dll does it work as 32bit or 64bit on a x64 operating system? [DllImport("user32.dll",EntryPoint="GetDC")] public static extern IntPtr GetDC(IntPtr hWnd); public static extern uint GetDC(uint hWnd); public static extern int GetDC(int hWnd); Thanks!

  • Jquery mouseover event issues

    - by Shaun
    Hi I am currently working on a project where I am using jQuery to animate a block of text on mouse over. The event listener is on the containing div (as shown by the code below) and works really well until the mouse is over the title (.views-field-title) which is absolutely above the containing div. The animation begins to jump almost as though it is starting over? What am I doing wrong? $('#interior_design .views-row').mouseover(function(){ $('.views-field-title', this).stop(true, true).animate( { height: '+=10px' }, { duration: 'fast'}); }); $('#interior_design .views-row').mouseout(function(){ $('.views-field-title', this).stop(true, true).animate( { height: '-=10px' }, { duration: 'fast'}); }); Link to dev server: http://viva.bangtest.co.uk/interior-design Note: this site is still in development as such the jQuery is only on the above linked page currently. I'm open to all suggestions.

  • Inaccurate Logarithm in Python

    - by Avihu Turzion
    I work daily with Python 2.4 at my company. I used the versatile logarithm function 'log' from the standard math library, and when I entered log(2**31, 2) it returned 31.000000000000004, which struck me as a bit odd. I did the same thing with other powers of 2, and it worked perfectly. I ran 'log10(2**31) / log10(2)' and I got a round 31.0 I tried running the same original function in Python 3.0.1, assuming that it was fixed in a more advanced version. Why does this happen? Is it possible that there are some inaccuracies in mathematical functions in Python?

  • How do I find hash value of a 3D vector ?

    - by brainydexter
    I am trying to perform broad-phase collision detection with a fixed-grid size approach. Thus, for each entity's position: (x,y,z) (each of type float), I need to find which cell does the entity lie in. I then intend to store all the cells in a hash-table and then iterate through to report (if any) collisions. So, here is what I am doing: Grid-cell's position: (int type) (Gx, Gy, Gz) = (x / M, y / M, z / M) where M is the size of the grid. Once, I have a cell, I'd like to add it to a hash-table with its key being a unique hash based on (Gx, Gy, Gz) and the value being the cell itself. Now, I cannot think of a good hash function and I need some help with that. Can someone please suggest me a good hash function? Thanks

  • How to correctly pop a modeless dialog from console using MFC

    - by Vertilka
    I need to create a console application that has a main() function and pop a modeless dialog, so the console can still work in parallel to the modeless dialog (do other work, like communicating with the modeless dialog). Whatever i tried, i could only pop a modal dialog. (where the console is in hold till the modal dialog close itself). When switching to modeless dialog using Create() and ShowWindow() the dialog is displayed without its controls and it freeze / block (you can see the hourglass cursor). 1) i tried to pop the modeless dialog from the main() function 2) i tried to pop the modeless dialog from the InitInstance() of a CWinApp derived class In all cases the modeless dialog freeze / block. I believe this is a one line solution. TNX,Vertilka

So please, which function can I use to get it right?
