  • [JS/jQuery] Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

  • jquery script that used to work is not working with jquery 1.4.2

    - by Zayatzz
    ... and i cant figure out why. The script is following: <script type="text/javascript" src="http://path/to/js/jquery-1.4.2.min.js"></script> <script type="text/javascript"> function openMediaPlayer() { $('#flashMovie').animate({'height':'333px'}); } function closeMediaPlayer() { $('#flashMovie').animate({'height':'80px'}); } jQuery(function($){ $('#videoholder').bind('mouseenter', function(){ openMediaPlayer(); }); $('#videoholder').bind('mouseleave', function(){ closeMediaPlayer(); }); }); </script> <div id="videoholder" style="height:80px;width:412px;"> <object width="412" height="80" type="application/x-shockwave-flash" id="flashMovie" name="flashMovie" style="height: 80px;" data="http://path/to/Player.swf"><param name="menu" value="false"><param name="bgcolor" value="#666666"><param name="allowFullscreen" value="true"><param name="flashvars" value="playlistURL=http://path/to/Player/data/playlist.xml"></object> </div> pure and simple resizing flash object. It worked with older(1.3.2) jquery verision. The animate just does not work. Can anyone tell me what i should change to get it working again? Alan.

  • vb.net Is there a simple way to add a sound to a button click

    - by user867621
    Is there a simple way of doing this I found this online and I am getting an error Declare Function apisndPlaySound Lib "winmm" Alias "sndPlaySoundA" _ (ByVal filename As String, ByVal snd_async As Long) As Long Function PlaySound(ByVal sWavFile As String) ' Purpose: Plays a sound.

End If End Function A call to PInvoke function 'WindowsApplication3!WindowsApplication3.Module1::apisndPlaySound' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

  • Is it possible that we override global variables?

    - by Ram Moj
    I have this function: function example(y) global TICTOC; tic TICTOC=5; toc end and I expect TICTOC=5 change the result of toc, since TICTOC is a global variable in tic and toc functions; but this is not the case; Does anyone know the reason? I like to know the answer, because I 'm worried to declare a global variable, which it's name has been declared global in some other functions, I'm not aware of. I saw this function in matlab 2008b help function tic % TIC Start a stopwatch timer. % TIC; any stuff; TOC % prints the time required. % See also: TOC, CLOCK. global TICTOC TICTOC = clock; function t = toc % TOC Read the stopwatch timer. % TOC prints the elapsed time since TIC was used. % t = TOC; saves elapsed time in t, does not print. % See also: TIC, ETIME. global TICTOC if nargout < 1 elapsed_time = etime(clock, TICTOC) else t = etime(clock, TICTOC); end thanks.

  • how to set style through javascript in IE immediately

    - by rezna
    Hi, recently I've encountered a problem with IE. I have a function function() { ShowProgress(); DoSomeWork(); HideProgress(); } where ShowProgress and HideProgress just manipulate the 'display' CSS style using jQuery's css() method. In FF everything is OK, and at the same time I change the display property to block, progress-bar appears. But not in IE. In IE the style is applied, once I leave the function. Which means it's never shown, because at the end of the function I simply hide it. (if I remove the HideProgress line, the progress-bar appears right after finishing executing the function (more precisely, immediately when the calling functions ends - and so there's nothing else going on in IE)). Has anybody encountered this behavior? Is there a way to get IE to apply the style immediately? I've prepared a solution but it would take me some time to implement it. My DoSomeWork() method is doing some AJAX calls, and these are right now synchronous. I assume that making them asynchronous will kind of solve the problem, but I have to redesign the code a bit, so finding a solution just for applying the style immediately would much simplier. Thanks rezna

  • how to send parameters to a web Services via SOAP?

    - by Alejandra Meraz
    Before I start: I'm programming for Iphone, using objective C. I have already implemented a call to a web service function using NSURLRequest and NSURLConnection and SOAP. The function then returns a XML with the info I need. The code is as follows: NSString *soapMessage = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" "<soap:Body>\n" "<function xmlns=\"http://tempuri.org/\" />\n" "</soap:Body>\n" "</soap:Envelope>\n"]; NSURL *url = [NSURL URLWithString:@"http://myHost.com/myWebService/service.asmx"]; //the url to the WSDL NsMutableURLRequest theRequest = [[NSMutableURLRequest alloc] initWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMessage length]]; [theRequest addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [theRequest addValue:msgLength forHTTPHeaderField:@"Content-Lenght"]; [theRequest setHTTPMethod:@"POST"]; [theRequest addValue:@"myhost.com" forHTTPHeaderField:@"Host"]; [theRequest addValue:@"http://tempuri.org/function" forHTTPHeaderField:@"SOAPAction"]; [theRequest setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; I basically copy and modified the soap request the web service gave as an example. i also implemented the methods didRecieveResponse didRecieveAuthenticationChallenge didRecievedData didFailWithError connectionDidFinishLoading. And it works perfectly. Now I need to send 2 parameters to the function: "location" and "module". I tried modifying the soapMessage like this: NSString *soapMessage = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n" "<soap:Body xmlns=\"http://tempuri.org/\" />\n" "<m:GetMonitorList>\n" "<m:location>USA</m:location>\n" "<m:module>DEVELOPMENT</m:module>\n" "</m:GetMonitorList>\n" "</soap:Body>\n" "</soap:Envelope>\n"]; But is not working...any thoughts how should I modify it? Extra info: it seems to be working... kind of. But the webservice return nothing. During the connection, the method didReceiveResponse execute once and the didFinishLoading method executes as well. But not even once the method didReceiveData. I wonder if, even though there is no USA locations, it will still send at least something? is there a way to know which are the parameters the function is waiting for? I don't have access to the source of the webservice but i can access the WSDL.

  • is it possible if callback in array_filter receive parameter ?

    - by justjoe
    i got this multiple array name $files[], who consist keys and values as below : [0] = Array ( [name] = index1.php [path] = http://localhost/php/gettingstarted/ [number] = 1 ) [1] = Array ( [name] = index10.php [path] = http://localhost/php/gettingstarted/ [number] = 2 ) [2] = Array ( [name] = index11.php [path] = http://localhost/php/gettingstarted/ [number] = 3 ) and i use this code to create new array consist of 'name' keys only. but it failed array_filter($files, "is_inarr_key('name')"); function is_inarr_key($array, $key) { //TODO : remove every array except those who got the same $key } and i got this error array_filter() [function.array-filter]: The second argument, 'is_inarr_key('name')', should be a valid callback in C:\xampp\htdocs\php\gettingstarted\index.php on line 15 so the queastion : 1. is it possible to make call-back function on array_filter has ability to receive parameter ? What is general rule of thumb on how to use callback in anyPHP built-in function ?

  • How to debug an external library (OpenCV) in Visual C++?

    - by neuviemeporte
    I am developing a project in VC++2008. The project uses the OpenCV library (but I guess this applies to any other library). I am working with the Debug configuration, the linker properties include the debug versions of the library .lib's as additional dependencies. In VC++ Directories under Tools|Options i set up the include directory, the .lib directory, the source directories for the library as well. I get an error while calling one of the functions from the library and I'd like to see exactly what that function is doing. The line that produces the error is: double error = cvStereoCalibrate(&calObjPointsM, &img1PointsM, &img2PointsM, &pointCountsM, &cam1M, &dist1M, &cam2M, &dist2M, imgSize, &rotM, &transM, NULL, NULL, cvTermCriteria(CV_TERMCRIT_ITER + CV_TERMCRIT_EPS, 100, 1e-5)); I set up a breakpoint at this line to see how the cvStereoCalibrate() function fails. Unfortunately the debugger won't show the source code for this function when I hit "Step into". It skips immediately to the cvTermCriteria() (which is a simple inline, macro-kinda function) and show its contents. Is there anything else I need to do to be able to enter the external library functions in the debugger? EDIT: I think the cvTermCriteria() function shows in the debugger, because it's defined in a header file, therefore immediately accesible to the project.

  • Event not triggering

    - by the Hampster
    I have no idea where to start on this one. I have a that does not appear until a button is clicked. This function call works: onclick="highlight('mod_sup_div', true);" function highlight(aDiv,show) { if (show) { Effect.Appear('Overlay',{duration: 0.5, to: .80}); Effect.Appear(aDiv,{duration: 0.5}) } else { Effect.Fade('Overlay',{duration: 0.5, to: .80}); Effect.Fade(aDiv,{duration: 0.5}) } } In the <div> I have a button to close the window. <p class="closer"><span onclick="highlight('mod_sup_div',false)">X</span></p> This does not work. The function is not even called, as I made a alert() the first line of the function at it does nothing. What is odd, is that onclick="Effect.Fade(aDiv,{duration: 0.5})" does work. Other simple javascript functions in the onclick="" work, except for the function call. Any help as to why this is happening would be very appreciated. Thanks, Dave

  • Excel 2007 UDF keeps failing, why?

    - by Zan
    I've been trying to browse info about this for a while now. The user defined functions in Excel 2007 just make no sense to me whatsoever. According to all the tutorials, it should be really simple. Just press alt + f11, insert a new module, and enter the VBA code there. At this point typing '=FUNCTIONNAME(parameters)' into any cell should make it work. It did, at first. Then upon closing and reopening the worksheet it stopped working. I checked to see that macros were enabled, but either way, that didn't help. Then I browsed the graphic UI from the function button to locate user defined functions. I found it there by name of 'MyExcelWorksheet.xls!FUNCTIONNAME.FUNCTIONNAME' and clicking that, it started working again. Now, a day later, I get back to working on this and it's broken, again. I just get #NAME? error or some "Function Arguments - Function doesn't use any arguments" -popup (translated from Finnish Excel, not sure what that msg is in English) when I select the function from the GUI. So what does it take to just create a function, and actually make it work and KEEP working? For the life of me I can't figure out why this has to be so difficult. :) I'm starting to think my company has some weird settings enabled or whatever, because judging by the lack of information I've found on the subject, this isn't supposed to happen.

  • Multiple asserts in single test?

    - by Gern Blandston
    Let's say I want to write a function that validates an email address with a regex. I write a little test to check my function and write the actual function. Make it pass. However, I can come up with a bunch of different ways to test the same function ([email protected]; [email protected]; test.test.com, etc). Do I put all the incantations that I need to check in the same, single test with several ASSERTS or do I write a new test for every single thing I can think of? Thanks!
