  • Clear the form once form submitted

    - by zurna
    Once the form submitted, response from another page is printed to #GameStorySys. But values entered to the form still stays there. Is it possible for the form values to disappear (but the form should still stay) once the form submitted? $("[name='GameStoryForm']").click(function() { $.ajax({ type: "POST", data: $("#GameStoryForm").serialize(), url: "content/commentary/index.cs.asp?Process=EditLiveCommentaryStory&CommentaryID=<%=Request.QueryString("CommentaryID")%>", success: function(output) { $('#GameStorySys').html(output); }, error: function(output) { $('#GameStorySys').html(output); } }); });

  • How to break closures in JavaScript

    - by Not a Name
    Is there any way to break a closure easily in JavaScript? The closest I have gotten is this: var src = 3; function foo () { return function () { return src; } } function bar (func) { var src = 9; return eval('('+func.toString()+')')(); // Line breaks closure } alert(bar(foo())); Which prints 9, instead of 3 as a closure would dictate. However, this approach seems kind of ugly to me, are there any better ways?

  • Using try vs if in python

    - by artdanil
    Is there a rationale to decide which one of try or if constructs to use, when testing variable to have a value? For example, there is a function that returns either a list or doesn't return a value. I want to check result before processing it. Which of the following would be more preferable and why? result = function(); if (result): for r in result: #process items or result = function(); try: for r in result: #process items except TypeError: pass; Related discussion: Checking for member existence in Python

  • Resetting Qt Style Sheet

    - by mree
    I've managed to style my QLineEdit to something like this: void Utilities::setFormErrorStyle(QLineEdit *lineEdit) { lineEdit->setStyleSheet( "background-color: #FF8A8A;" "background-image: url(:/resources/warning.png);" "background-position: right center;" "background-repeat: no-repeat;" ""); } I called the function using Utilities *util = new Utilities; util->setFormErrorStyle(lineNoStaf); The flow should be something like this: User open form User fill data User submit data Got error Use setFormErrorStyle() User edit the text in the QLineEdit and the style disappear This function should be reusable over and over again, but how can I connect QLineEdit signal such as textChanged() to a function in other class that will reset the Style Sheet and then disconnect the signal so that it won't be running continuously every time the text changed ?

  • pointers for getting elements of an array in C

    - by Manolo
    I am a newbie in C and I would like to get the elements of an array with a function, I have tried different options, but I still do not get the elements. My function is: void getelements(int *a, int cl) { int *p; for (p=&a[0];p<&a[cl];p++) { printf("%d\n",*p); } } I know that the solution should work like that, but it only prints the first element and then memory positions. I am calling my function with: int v={10,12,20,34,45}; getelements(&v,5); Any help? I need to use arithmetic of pointers. Thanks

  • jQuery: Scroll the window then addClass() - how to callback

    - by carillonator
    Inside a jQuery event handler, I would like to scroll the window and then add a class to something. This is my code: $('#foo').click(function() { window.scrollTo(y); $('#bar').addClass('active'); }); $(window).scroll(function() { $('#bar').removeClass('active'); }); Notice I have another handler to remove that same class whenever the window is scrolled. The scrolling part works fine, but seems to run asynchronously, so removeClass() happens after addClass() but before the scrolling is finished. I don't know how to do this in plain javascript. I know there is a jQuery scrollTop() function that does the same thing (but seems to have cross-browser issues), but it doesn't accept a callback. What I really need is a callback to add the class after the scrolling is finished. thanks!

  • crontable OR conditions

    - by matt
    Crontable parameters seem to function as 'ands' conditions. So the example 0 9-5 * * 1-5 Runs when the conditions are met "minute is zero AND hour is between 9 and 5 AND day is between monday and friday". What I'd like is an 'or' function, so I can say "run monday to friday OR the 8th day of the month". Does such a thing exist? I realise you could add two entries, but with lots of entries it adds something to forget.

  • Setting an attribute in Jquery not working

    - by Probocop
    Hi, I have the following function which limits the amount of characters you can enter into a text area. What's meant to happen is, if the text length is higher than the text limit, set an attribute of disabled="disabled" on the submit button, but it isn't getting set, my function code is as follows: function limitChars(textid, limit, infodiv) { var text = $('#'+textid).val(); var textlength = text.length; if(textlength > limit) { $('#' + infodiv).html('You cannot write more then '+limit+' characters!'); $('input#submit').attr('disabled', 'disabled'); } else { $('#' + infodiv).html('You have '+ (limit - textlength) +' characters left.'); } } Any ideas?

  • How to address thread-safety of service data used for maintaining static local variables in C++?

    - by sharptooth
    Consider the following scenario. We have a C++ function with a static local variable: void function() { static int variable = obtain(); //blahblablah } the function needs to be called from multiple threads concurrently, so we add a critical section to avoid concurrent access to the static local: void functionThreadSafe() { CriticalSectionLockClass lock( criticalSection ); static int variable = obtain(); //blahblablah } but will this be enough? I mean there's some magic that makes the variable being initialized no more than once. So there's some service data maintained by the runtime that indicates whether each static local has already been initialized. Will the critical section in the above code protect that service data as well? Is any extra protection required for this scenario?

  • getElementById does return null

    - by pbcoder
    I have following function: $('canvas').createWindow('xyz', 500, 600); And js-code behind is: var $ = function(element) { if (this.constructor !== $) { return new $(element); } alert(element); var windowObj = document.getElementById(element); this.createWindow = function(src, width, height) { if(width != "" && height != "") { windowWidth = windowObj.style.width = width + 'px'; windowHeight = windowObj.style.height = height + 'px'; } }; }; But the problem is that JS says windowObj is null, alert(element) works fine! Thanks for your help!

  • Do i need a hashtag in Javascript to pass as a Div

  • AJAX with jQuery not returning data

    - by James P
    This is my Javascript: $(document).ready(function() { $('#like').bind('keydown', function(e) { if(e.keyCode == 13) { var likeMsg = $('#like').val(); if(likeMsg) { // Send the AJAX request to like.php $.ajax({ url: 'like.php', success: function(data) { alert('Content: ' + data); } }); } } }); }); And this is my like.php file: <?php echo "It works! :)"; ?> When I press enter on the #like input, it seems the AJAX request is sent and an alert box comes up saying: Content:, but there's no data being sent back from like.php... I have checked if the file exists and if it's in the same directory and whatever and it is, so I'm pretty much clueless atm. Does anyone know what could be wrong here? Cheers.

  • Vew not updating after scope update

    - by bsparacino
    Here is a very simple example of what I am trying to do Athlete.save(athlete,function(result) { $scope.athlete = result.athlete; }); The issue is that the $scope.athlete variable does not update in my view. In order to get it to update I have to do this Athlete.save(athlete,function(result) { $scope.athlete.fname = result.athlete.fname; $scope.athlete.lname= result.athlete.lname; $scope.athlete.gender= result.athlete.gender; .... }); This gets annoying very quickly. With the first block of code it's as if angular does not know that my $scope.athlete variable has been updated. This function is triggered from an ng-click, not some jquery call, I am doing it the angular way as far as I know. here is a simpler case I made: http://plnkr.co/edit/lMCPbzqDOoa5K4GXGhCp

  • Strange behaviour of mb_detect_order() in PHP

    - by termopro
    I would like to detect encoding of some text (using PHP). For that purpose i use mb_detect_encoding() function. The problem is that the function returns different results if i change the order of possible encodings with mb_detect_order() function. Consider the following example $html = <<< STR ????????????????????????????????????????????????????????????????????????????????????????????????????????? STR; mb_detect_order(array('UTF-8','EUC-JP', 'SJIS', 'eucJP-win', 'SJIS-win', 'JIS', 'ISO-2022-JP','ISO-8859-1','ISO-8859-2')); $originalEncoding = mb_detect_encoding($str); die($originalEncoding); // $originalEncoding = 'UTF-8' However if you change the order of encodings in mb_detect_order() the results will be different: mb_detect_order(array('EUC-JP','UTF-8', 'SJIS', 'eucJP-win', 'SJIS-win', 'JIS', 'ISO-2022-JP','ISO-8859-1','ISO-8859-2')); die($originalEncoding); // $originalEncoding = 'EUC-JP' So my questions are: Why is that happening ? Is there a way in PHP to correctly and unambiguously detect encoding of text ?

    Take the following example: $.fn.foo = function() { var $input = $('<input type="text"/>'); var $button_one = $('<button>One</button>'); var $button_two = $('<button>Two</button>'); $button_one.click(function(){ $input.val('hey'); }); $button_two.click(function(){ $input.replaceWith( $input.val('').clone( true ) ); }); this.append($input, $button_one, $button_two); }; Check the demo: http://jsbin.com/ezexah/1/edit Now click "one" and you should see "hey" in the input. Next click "two" and then click "one" again and it doesn't work. Even using the true option in clone to copy all events it still does not work. Any ideas?

    I'm using the following in order to have on screen display of each value of a checkbox that's selected with great results when it's displayed inside a textbox. I'd like to change it so that I can show a real time display in a div as html instead of a textbox. A link to a working demo is here and below is the script. I know it's probably a basic line or two but i'm still learning and new. thanks! function updateTextArea() { var allVals = []; $('#c_b :checked').each(function() { allVals.push($(this).val()); }); $('#t').val(allVals) } $(function() { $('#c_b input').click(updateTextArea); updateTextArea(); });

  • PHP: Remove all fcn not acting as expected, Code Inside

    - by Josh K
    I made this simple function (remove all $elem from $array): function remall($array, $elem) { for($i=0; $i < count($array); $i++) if($array[$i] == $elem) unset($array[$i]); $newarray = array_values($array); return $newarray; } But it isn't working perfectly, here are some inputs and outputs $u = array(1, 7, 2, 7, 3, 7, 4, 7, 5, 7, 6, 7); $r = remall($u, 7); Output of $r: 12345767 $n = array(7, 7, 1, 7, 3, 4, 6, 7, 2, 3, 1, -3, 10, 11, 7, 7, 7, 2, 7); $r = remall($n, 7); Output of $r: 1346231-30117727 Notice how there are still 7s in my outputs. Also, My function will only be removing numbers from an array. Let me know if you spot something, thanks.
