  • JQuery plugin: catch events for clicking/tabbing into and out of an input box

    - by poswald
    I'm creating a Javascript JQuery Timepicker control plugin (which I hope to open source soon) and I would like some advice on how to best register the events in the cleanest way. The control will attach to an <input> box and provide a graphical way to enter times of day ( 14:25, 2:45 AM, etc...). It does this by adding a <div> after the input box. What I want is to bind an openControl() function that fires when the input is clicked or tabbed to, and a closeControl() function that fires when the input box is tabbed away from or deselected but not if the control itself is clicked. That is, I don't want to close the control if you're clicking inside of the control's <input> or the <div>. Here's what I have been doing to try to get there: /* Close the control attached to the passed inputNode */ function closeContainer(inputNode, options) { $input = $(inputNode); if ( $input.next().is(':visible')) { $input.next().hide(options.hideAnim, options.hideOptions, options.hideDuration, options.onHide ); } } /* Open the control */ function openContainer(node, options) { $input = $(node); $input.next().show(options.showAnim, options.showOptions, options.showDuration, options.onShow ); // bind a click handler for closing the contol $("body").bind('click', function (e) { $('.time-control').each( function () { $input = $(this).prev(); // only close if click is outside of the control or the input box if (jQuery.contains(this, e.target) || ($input.get(0) === e.target) ) { closeContainer($input, options); setTime($input, $input.next(), options); } else { closeContainer($input, options); } }); }); } I want to add support for tabbing in/out but I feel like this approach is wrong. Focus/Blur wasn't working well because the blur event fires if you click on the control. Should I be using those events but filtering out if they are inside the control's div? Anyone have a better way of doing this? Thanks!

  • How to catch YouTube embed code and turn into URL

    - by Jonathan Vanasco
    I need to strip YouTube embed codes down to their URL only. This is the exact opposite of all but one question on StackOverflow. Most people want to turn the URL into an embed code. This question addresses the usage patttern I want, but is tied to a specific embed code's regex ( Strip YouTube Embed Code Down to URL Only ) I'm not familiar with how YouTube has offered embeds over the years - or how the sizes differ. According to their current site, there are 2 possible embed templates and a variety of options. If that's it, I can handle a regex myself -- but I was hoping someone had more knowledge they could share, so I could write a proper regex pattern that matches them all and not run into endless edge-cases. The full use case scenario : user enters content in web based wysiwig editor backend cleans out youtube & other embed codes; reformats approved embeds into an internal format as the text is all converted to markdown. on display, appropriate current template/code display for youtube or other 3rd party site is generated At a previous company, our tech-team devised a plan where YouTube videos were embedded by listing the URL only. That worked great , but it was in a CMS where everyone was trained. I'm trying to create a similar storage, but for user-generated-content.

  • Catch access to undefined property in JavaScript

    - by avri
    The Spider-Monkey JavaScript engine implements the noSuchMethod callback function for JavaScript Objects. This function is called whenever JavaScript tries to execute an undefined method of an Object. I would like to set a callback function to an Object that will be called whenever an undefined property in the Object is accessed or assigned to. I haven't found a noSuchProperty function implemented for JavaScript Objects and I am curios if there is any workaround that will achieve the same result. Consider the following code: var a = {}; a.__defineGetter__("bla", function(){alert(1);return 2;}); alert(a.bla); It is equivalent to [alert(1);alert(2)] - even though a.bla is undefined. I would like to achieve the same result but to unknown properties (i.e. without knowing in advance that a."bla" will be the property accessed)

  • Can't catch newConnection() signal from QTcpServer

    - by Bob
    I am trying to make a simple server thread in QT to accept a connection, however although the server is listening (I can connect with my test app) I can't get the newConnection() signal to be acted on. Any help as to what I'm missing here would be much appreciated! class CServerThread : public QThread { Q_OBJECT protected: void run(); private: QTcpServer* server; public slots: void AcceptConnection(); }; void CServerThread::run() { server = new QTcpServer; QObject::connect(server, SIGNAL(newConnection()), this, SLOT(AcceptConnection())); server-listen(QHostAddress::Any, 1000); // Any port in a storm exec(); // Start event loop } void CServerThread::AcceptConnection() { OutputDebugStringA("\n***** INCOMING CONNECTION"); // This is never called! }

  • Catch Id (INT AUTO INCREMENT) of a Record after INSERT INTO Statement

    - by Johannes
    This is my first time I use MySQL as datastorage for my C# Application, as I've seen that there is no UNIQUEIDENTIFIER type as in SQL server I decieded to use INT with AUTO_INCREMENT, my problem is now if I execute a INSERT, how may I get the ID of the Record I just added. My quick and dirty solution has been to execute a SELECT MAX(ID) FROM table Statement. But this doesn't seem consistent. I belive there is a better solution something like mysql_insert_id() (PHP). Any Idea how to resolve this in C#?

  • (Android) How to catch a "ring" event?

    - by rockit
    Hi android developers! I'm clearly a newb, and I was wondering if anyone knows how I can detect a "ring" event on my cellphone through the android sdk? Generally I want to do something with the phone when it begins ringing! Any thoughts? If you want to simply point me to a page in the api documents that would be a good answer for me, I just don't know how to start my research!

  • Catch a PHP Object Instantiation Error

    - by Rob Wilkerson
    It's really irking me that PHP considers the failure to instantiate an object a Fatal Error (which can't be caught) for the application as a whole. I have set of classes that aren't strictly necessary for my application to function--they're really a convenience. I have a factory object that attempts to instantiate the class variant that's indicated in a config file. This mechanism is being deployed for message storage and will support multiple store types: DatabaseMessageStore FileMessageStore MemcachedMessageStore etc. A MessageStoreFactory class will read the application's preference from a config file, instantiate and return an instance of the appropriate class. It might be easy enough to slap a conditional around the instantiation to ensure that class_exists(), but MemcachedMessageStore extends PHP's Memcached class. As a result, the class_exists() test will succeed--though instantiation will fail--if the memcached bindings for PHP aren't installed. Is there any other way to test whether a class can be instantiated properly? If it can't, all I need to do is tell the user which features won't be available to them, but let them continue one with the application. Thanks.

  • How to catch unintentional function interpositioning with GCC?

    - by SiegeX
    Reading through my book Expert C Programming, I came across the chapter on function interpositioning and how it can lead to some serious hard to find bugs if done unintentionally. The example given in the book is the following: my_source.c mktemp() { ... } main() { mktemp(); getwd(); } libc mktemp(){ ... } getwd(){ ...; mktemp(); ... } According to the book, what happens in main() is that mktemp() (a standard C library function) is interposed by the implementation in my_source.c. Although having main() call my implementation of mktemp() is intended behavior, having getwd() (another C library function) also call my implementation of mktemp() is not. Apparently, this example was a real life bug that existed in SunOS 4.0.3's version of lpr. The book goes on to explain the fix was to add the keyword static to the definition of mktemp() in my_source.c; although changing the name altogether should have fixed this problem as well. This chapter leaves me with some unresolved questions that I hope you guys could answer: Should our software group adopt the practice of putting the keyword static in front of all functions that we don't want to be exposed? Does GCC have a way to warn about function interposition? We certainly don't ever intend on this happening and I'd like to know about it if it does. Can interposition happen with functions introduced by static libraries? Thanks for the help.

  • [C++] Boost test: catch user defined exceptions

    - by user231536
    If I have user defined exceptions in my code, I can't get Boost test to consider them as failures. For example, BOOST_AUTO_TEST_CASE_EXPECTED_FAILURES(MyTest,1) BOOST_AUTO_TEST_CASE(MyTest) { // code which throws user defined exception, not derived from std::exception. } I get a generic message: Caught exception: .... unknown location(0):.... It does not recognize this error as a failure since it is not a std::exception. So it does not honor the expected_failures clause. How do I enforce that the piece of code should always throw an exception? THis seems to be a useful thing to want. In case future code changes cause the code to pass and the exception is not thrown, I want to know that.

  • howto catch jQuery for multiple links but not all

    - by user247245
    I'm trying to dig into jQuery but would like some feedback on how to do things the best way, I have a list with items, which each contains a hidden div that should show upon click on it's parent, list div:ed item1 with link hidden div div:ed item2 with link hidden div .. My current solution is to trace the calling link by it's id and then reusing that ID for showing the correct hidden one: $(document).ready(function() { //jQ should only trigger on links with id="cmLinkINT" $("a").click(function() { //see if it's a comment request. var s = $(this).attr("id"); if (s.indexOf('cmLink') != -1) { //ok, it was a 'show'-link, get the id.. var j = s.substring(6); //ok, now I have the id i want to show (detailsINT) return false; } }); }); What's not clear to me is the best approach, Should I use id for requesting a or trace the id of the parent div. How to avoid that the code triggers on any link? Class? Thankful for any feedback, regards //t

  • Catch/Intercept all mouse clicks

    - by Hallik
    I have this simple script that catches all mouse clicks, unless you click on something that actually works. Links, flash videos, etc. How can I adjust this so no matter what a user clicks on, before the video loads, new page loads, etc. It sends the simple GET request I built? (function($) { $.fn.saveClicks = function() { $(this).bind('mousedown.clickmap', function(evt) { var clickDocument = (document.documentElement != undefined && document.documentElement.clientHeight != 0) ? document.documentElement : document.body; var width = clickHeatDocument.clientWidth != undefined ? clickDocument.clientWidth : window.innerWidth; var height = clickHeatDocument.clientHeight != undefined ? clickDocument.clientHeight : window.innerHeight; var scrollx = window.pageXOffset == undefined ? clickDocument.scrollLeft : window.pageXOffset; var scrolly = window.pageYOffset == undefined ? clickDocument.scrollTop : window.pageYOffset; var x = evt.clientX + scrollx; var y = evt.clientY + scrolly; $.get('/click-save.php', { "x":evt.pageX, "y":evt.pageY, "click":"true", "w":width, "h":height, "l":escape(document.location.pathname), "d":escape(document.domain) }); }); }; })(jQuery); $(function() { $(document).saveClicks(); });

  • jQuery catch img

    - by Happy
    We have a script used for each .item: $(".item").each(function(){ item_link = "http://..."; block = $('.block', this); $.get(item_link, function(data) { var src = $('img.slide', data).attr('src'); block.html(src); }); }); item_link variable is uniquie for each query. There can be 100 .item or more. The problem is - server has limit on connections at the same time, that why some .item get var src, some not. The best solution is to use just one .get at the same time. I think there should be some counter, if .get is finished - it gives message "I'm finished, you can start" to the next .get and so on. How to do that? Thanks.

  • Catch all javascript errors and send them to server

    - by ssaboum
    Hi everyone, i wandered if anyone had experience in handling javascript errors globally and send them from the client browser to a server. I think my point is quite clear, i want to know every exceptions, errors, compilation errors, ... that happens on the client side and send them to the server to report them. I'm mainly using mootools and head.js (for the js side) and django for the server side (not that it matters...). Thank you for your help. Regards.
