  • jquery for ruby on rails

    - by Cezar
    Hello, I am tying to use this code http://gist.github.com/110410 to dump Prototype in favor of jQuery but I do have a problem. This is my HTML (a link_to generated link): <a onclick="var f = document.createElement('form'); f.style.display = 'none'; this.parentNode.appendChild(f); f.method = 'POST'; f.action = this.href;var s = document.createElement('input'); s.setAttribute('type', 'hidden'); s.setAttribute('name', 'authenticity_token'); s.setAttribute('value', 'Mi6RcR6YDyvg2uNwGrpbeIJutSHa2fYboU37wSDE7AU='); f.appendChild(s);f.submit();return false;" class="post add_to_cart " href="/line_items?product_id=547">Add to cart</a> Issue: Everything works as it should except that the page does a reload. I suspect that the submit gets thru which causes a page reload. Is there an elegant way to prevent that ? return false; doesn't seem to cut it in this case.

  • Is something along the lines of nested memoization needed here?

    - by Daniel
    System.Transactions notoriously escalates transactions involving multiple connections to the same database to the DTC. The module and helper class, ConnectionContext, below are meant to prevent this by ensuring multiple connection requests for the same database return the same connection object. This is, in some sense, memoization, although there are multiple things being memoized and the second is dependent on the first. Is there some way to hide the synchronization and/or mutable state (perhaps using memoization) in this module, or perhaps rewrite it in a more functional style? (It may be worth nothing that there's no locking when getting the connection by connection string because Transaction.Current is ThreadStatic.) type ConnectionContext(connection:IDbConnection, ownsConnection) = member x.Connection = connection member x.OwnsConnection = ownsConnection interface IDisposable with member x.Dispose() = if ownsConnection then connection.Dispose() module ConnectionManager = let private _connections = new Dictionary<string, Dictionary<string, IDbConnection>>() let private getTid (t:Transaction) = t.TransactionInformation.LocalIdentifier let private removeConnection tid = let cl = _connections.[tid] for (KeyValue(_, con)) in cl do con.Close() lock _connections (fun () -> _connections.Remove(tid) |> ignore) let getConnection connectionString (openConnection:(unit -> IDbConnection)) = match Transaction.Current with | null -> new ConnectionContext(openConnection(), true) | current -> let tid = getTid current // get connections for the current transaction let connections = match _connections.TryGetValue(tid) with | true, cl -> cl | false, _ -> let cl = Dictionary<_,_>() lock _connections (fun () -> _connections.Add(tid, cl)) cl // find connection for this connection string let connection = match connections.TryGetValue(connectionString) with | true, con -> con | false, _ -> let initial = (connections.Count = 0) let con = openConnection() connections.Add(connectionString, con) // if this is the first connection for this transaction, register connections for cleanup if initial then current.TransactionCompleted.Add (fun args -> let id = getTid args.Transaction removeConnection id) con new ConnectionContext(connection, false)

  • Manually changing keyboard orientation for a view that's on top of a camera view

    - by XKR
    I'm basically trying to reproduce the core functionality of the "At Once" app. I have a camera view and another view with a text view on it. I add both views to the window. All is well so far. [window addSubview:imagePicker.view]; [window addSubview:textViewController.view]; I understand that the UIImagePickerController does not support autorotation, so I handle it manually by watching UIDeviceOrientationDidChangeNotifications and applying the necessary transforms to the textViewController.view. Now, the problem here is the keyboard. If I do nothing, it just stays in portrait mode. I can get it to rotate by adding the following code to the notification handler. [[UIApplication sharedApplication] setStatusBarOrientation:interfaceOrientation]; [textView resignFirstResponder]; [textView becomeFirstResponder]; However, the following simple test produces weird behavior. Start the app in portrait mode. Rotate the device 90 degrees clockwise. Rotate the device 90 degrees counterclockwise (back to the initial position). Rotate the device 90 degrees clockwise. After step 4, instead of the landscape-mode keyboard, the portrait-style keyboard is shown, skewed to fit in the landscape keyboard frame. Perhaps my approach is wrong from the start. I was wondering if anyone has been able to reliably make the keyboard change its orientation in response to setStatusBarOrientation.

  • CodeIgniter: problem using foreach in view

    - by krike
    I have a model and controller who gets some data from my database and returns the following array Array ( [2010] => Array ( [year] => 2010 [months] => Array ( [0] => stdClass Object ( [sales] => 2 [month] => Apr ) [1] => stdClass Object ( [sales] => 1 [month] => Nov ) ) ) [2011] => Array ( [year] => 2011 [months] => Array ( [0] => stdClass Object ( [sales] => 1 [month] => Nov ) ) ) ) It shows exactly what it should show but the key's have different names so I have no idea on how to loop through the years using foreach in my view. Arrays is something I'm not that good at yet :( this is the controller if you need to know: function analytics() { $this->load->model('admin_model'); $analytics = $this->admin_model->Analytics(); foreach ($analytics as $a): $data[$a->year]['year'] = $a->year; $data[$a->year]['months'] = $this->admin_model->AnalyticsMonth($a->year); endforeach; echo"<pre style='text-align:left;'>"; print_r($data); echo"</pre>"; $data['main_content'] = 'analytics'; $this->load->view('template_admin', $data); }//end of function categories()

  • javascript check function for a html form

    - by Reteras Remus
    I'm having a problem with a HTML form (name, e-mail, subject, message), I can't validate the form if it was completed correct or not. I want to call a javascript function when the form is submitted and alert if a field wasn't completed correct. My problem is with the submit button, because my boss said that I must use he's own php function to insert a submit button. The php function looke like: function normal_button($text, $width, $param = '', $class = 'button-blue') { $content = '<div class="'.$class.'" style="width:'.$width.'px;" '.$param.'>'.$text.'</div>'; return $content; } and how I call the function: echo normal_button('Send it', '100', 'onclick="document.getElementById(\'emailForm\').submit();" '); I tried to call the js function declaring the onSubmit="return checkForm(this)" in the <form action='email.php' method='post'> HTML form, but I can't "catch" the submit. Also I tried to catch it with jquery, $(document).ready(function() { $('.normal_button').click(function() { }); ); but I can't return false if a field wasn't completed correct. I must use he's PHP function to insert the submit button, but how can I "catch" the fields, how can I validate them? Any suggestions? Thank you !

  • How to flatten list of options using higher order functions?

    - by Synesso
    Using Scala 2.7.7: If I have a list of Options, I can flatten them using a for-comprehension: val listOfOptions = List(None, Some("hi"), None) listOfOptions: List[Option[java.lang.String]] = List(None, Some(hi), None) scala> for (opt <- listOfOptions; string <- opt) yield string res0: List[java.lang.String] = List(hi) I don't like this style, and would rather use a HOF. This attempt is too verbose to be acceptable: scala> listOfOptions.flatMap(opt => if (opt.isDefined) Some(opt.get) else None) res1: List[java.lang.String] = List(hi) Intuitively I would have expected the following to work, but it doesn't: scala> List.flatten(listOfOptions) <console>:6: error: type mismatch; found : List[Option[java.lang.String]] required: List[List[?]] List.flatten(listOfOptions) Even the following seems like it should work, but doesn't: scala> listOfOptions.flatMap(_: Option[String]) <console>:6: error: type mismatch; found : Option[String] required: (Option[java.lang.String]) => Iterable[?] listOfOptions.flatMap(_: Option[String]) ^ The best I can come up with is: scala> listOfOptions.flatMap(_.toList) res2: List[java.lang.String] = List(hi) ... but I would much rather not have to convert the option to a list. That seems clunky. Any advice?

  • Load some data from database and hide it somewhere in a web page

    - by kwokwai
    Hi all, I am trying to load some data (which may be up to a few thousands words) from the database, and store the data somewhere in a html web page for comparing the data input by users. I am thinking to load the data to a Textarea under Div tag and hide the the data: <Div id="reference" style="Display:none;"> <textarea rows="2" cols="20" id="database"> html, htm, php, asp, jsp, aspx, ctp, thtml, xml, xsl... </textarea> </Div> <table border=0 width="100%"> <tr> <td>Username</td> <td> <div id="username"> <input type="text" name="data" id="data"> </div> </td> </tr> </table> <script> $(document).ready(function(){ //comparing the data loaded from database with the user's input if($("#data").val()==$("#database").val()) {alert("error");} }); </script> I am not sure if this is the best way to do it, so could you give me some advice and suggest your methods please.

  • Is ther a Designer for MFC in Visual Studio like for windows forms in .NET?

    - by claws
    Hello, I'm a .NET programmer. I've never developed anything in MFC. Currently I had to write a C++ application (console) for some image processing task. I finished writing it. But the point is I need to design GUI also for this. Well, there won't be anything complex. Just a window with few Buttons, RadioButtons, Check Boxes, PicturesBox & few sliders. thats it. I'm using VS 2008 and was expecting a .NET style form designer. Just to test, I created a MFC project (with all default configuration) and these files were created by default: ChildFrm.cpp MainFrm.cpp mfc.cpp mfcDoc.cpp mfcView.cpp stdafx.cpp Now, I'm unable to find a Designer. There is no View Designer. I've opened all the above *.cpp and in the code editor right clicked to see "Designer View". ToolBox is just empty because I'm in code editor mode. When I built the project. This is the window I get. How to open a designer?

  • Positioning DIV element at center of screen

    - by iSumitG
    I want to position a DIV (or a TABLE) element at the center of screen irrespective of screen size. In other words, the space left on 'top' and 'bottom' should be equal and space left on 'right' and 'left' sides should be equal. How to do it? Note: I prefer a complete CSS solution, but if is not possible without Javascript then using Javascript is also fine. I am trying the following but it is not working: <body> <div style="top:0px; border:1px solid red;"> <table border="1" align="center"> <tr height="100%"> <td height="100%" width="100%" valign="middle" align="center"> We are launching soon! </td> </tr> </table> </div> </body> Note: It is either way fine if the DIV element (or TABLE) scrolls with the website or not. Just want it to be at center when page loads.

  • Table overflow working in Chrome and IE but not Firefox

  • Delegate Methods Not Firing on Search Results Table

    - by Slinky
    All, I have a UITableView w/detail, with a Search bar, created from code. Works fine on selected items except it doesn't work when an item is clicked from the search results; no delegate methods fire.

  • OpenCV. cvFnName() works, but cv::FunName() doesn't work

    - by Innuendo
    I'm using OpenCV to write a plugin for a simulator. I've made an OpenCV project (single - not a plugin) and it works fine. When I added OpenCV libs to the plugin project, I added all libs required. Visual Studio 2010 doesn't highlight any code line with red. All looks fine and compiles fine. But in execution, the program halts with a Runtime Error on any cv::function. For example: cv::imread, or cv::imwrite. But if I replace them with cvLoadImage() and cvSaveImage(), it works fine. Why does this happen? I don't want to rewrite the whole script in old-api-style (cvFnName). It means I should change all Mat objects to IplImages, and so on. UPDATE: // preparing template ifstream ifile(tmplfilename); if ( !FILE_LOADED && ifile ) { // loading template file Mat tmpl = cv::imread(tmplfilename, 1); // << here occurs error FILE_LOADED = true; } Mat src; Bmp2Mat(hDC, hBitmap, src); TargetDetector detector(src, tmpl); detector.detectTarget(); If I change to: if ( !FILE_LOADED && ifile ) { IplImage* tmpl = 0; tmpl = cvLoadImage(tmplfilename, 1); // no error occurs } And then no error occurs. Early it displayed some Runtime Error. Now, I wanted to copy exact message and it just crashes the application (simulator, what I am pluginning). It displays window error - to kill process or no. (I can't show exact message, because I'm using russian windows now)

  • Why do I get errors when using unsigned integers in an expression with C++?

    - by neuviemeporte
    Given the following piece of (pseudo-C++) code: float x=100, a=0.1; unsigned int height = 63, width = 63; unsigned int hw=31; for (int row=0; row < height; ++row) { for (int col=0; col < width; ++col) { float foo = x + col - hw + a * (col - hw); cout << foo << " "; } cout << endl; } The values of foo are screwed up for half of the array, in places where (col - hw) is negative. I figured because col is int and comes first, that this part of the expression is converted to int and becomes negative. Unfortunately, apparently it doesn't, I get an overflow of an unsigned value and I've no idea why. How should I resolve this problem? Use casts for the whole or part of the expression? What type of casts (C-style or static_cast<...)? Is there any overhead to using casts (I need this to work fast!)? EDIT: I changed all my unsigned ints to regular ones, but I'm still wondering why I got that overflow in this situation.

  • Using Maven for maintaining product documentation

    - by Waldheinz
    We are using Maven for building a Java server-style application. It consists of several modules (in a single Maven "reactor") which can be plugged together to generate a final product (essentially a .jar) with the features enabled that the customer needs. All the internals are documented using JavaDoc and all, but that's not what you can give to the customer to find out how to get the thing running. Currently we have an OpenOffice document which serves as end-user documentation. I'd like to integrate this documentation into the Maven build process where each module's documentation is maintained (hand-edited) together with the Module's sources and the final document can reference the required Module documentation sections, add some friendly foreword and, if possible at all, can reference into the JavaDocs. Ultimately, the document should be output as a PDF. Is there any experience on Maven plugins can help with this? Is DocBook the right tool? Maybe Latex? Or something completely different? A sound "stick with OpenOffice and some text blocks" could be an answer, too.

  • JQuery AJAX returned too much data that I had not requested

    - by kwokwai
    Hi all, I am using CakePHP 1.26 and CDN JQuery in this URL: http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js In a HTML web page, I have these lines of code: $.ajax({ type: "POST", url: "http://mywebsite.com/controllers/avail/"+curl, success: function(data) { alert(data);} }); and in the PHP page, I got another few lines of code: function avail($uname){ $result1=$this->Site1->User->findByusername($uname); if($result1){ return 1; } else{ return 0; } } As you see, the Avail function will return either zero or one. But there was some redundant data returned from the server, what I saw in the Alert box was somthing like this (rather than 0 or 1): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Missing Method in Controller</title> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script> <style type="text/css"> /* CSS Document */ /*PAGE LAYOUT*/ 0

  • Whose fault is a NullReferenceException?

    - by stefan.at.wpf
    I'm currently working on a class which exposes an internal List through a property. The List shall and can be modified. The problem is, entries in the internal list could be set to null from outside the class. My code actually looks like this: class ClassWithList { List<object> _list = new List<object>(); // get accessor, which however returns the reference to the list, // therefore the list can be modified (this is intended) public List<object> Data { get { return _list; } } private void doSomeWorkWithTheList() { foreach(object obj in _list) // do some work with the objects in the list without checking for null. } } So now in the doSomeWorkWithTheList() I could always check whether the current list entry is null or I could just asume that the person using this class doesn't have the great idea to set entries to null. So finally the questions end up in: Whose fault is a NullReferenceException in this case? Is it the fault of the class developer not checking everything for null (which would make code generally - not only in this class - more complex) or is it the fault of the user of this class, as setting a List entry to null doesn't really make sense? I'd tend to generally not check values for null except in some really special cases. Is this a bad style or de facto standard / standard in praxis? I know there's probably no ultimate answer for this, I'm just missing enough experience for such thing and therefore wondering what other developers think about such cases and want to hear what's done in reality about checking null (or not).

  • IE7 Problem with sIFR when <br> is inside an H3

    - by David Fox
    I have a problem I just discovered when viewing certain pages in IE7. If I have a very long header that wraps to a second line, or worse, if I put a BR in the middle, that throws off the spacing. One page to look at: broken example1 You'll notice that the margin at the top of the page gets offset as the headings are rendered, throwing everything off. I'm using code like this: <h3 style="margin:0"><a href="../books/msc1.html">Middle School Confidential™<br> Book 1: Be Confident in Who You Are</a></h3> but repeated many times to exaggerate the problem. I tried another test where I removed the BR and let the lines wrap naturally. This is an improvement in terms of the spacing, but it doesn't fix the problem. (Same URL but make it m1.html) In the third example, each heading takes up only one line (m2.html) One option would be to just split up the heading onto two lines, each with its on H tags. But since these are links, then it will appear that the first line might go to one place, and the second to another, since they wouldn't change color simultaneously as you roll over them. So, any solutions to this? I believe I have the current version of sIFR 3. I don't want to upgrade to IE8 until I know this is resolved. Thanks!

  • How to hide the title bar while application is loading and show it when it finishes loading?

    - by Arci
    I have an application which uses a custom title bar. However, when my application launches, I noticed that the default title bar is shown for a brief period of time. My problem is I don't want to show the default title bar while my application is loading. How do I hide the title bar while my application is loading so that there will be no hint of it and then show it afterwards? So far, I tried the following solutions but none have worked: Hide the title bar in XML and then set the custom title bar in code. (Problem encountered: I received an error message saying: "You cannot combine custom titles with other title features".) In XML: <item name="android:windowNoTitle">true</item> In onCreate method: requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); //... some code goes here getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title_header); Set the size of the title bar in XML to 0. Then change it's size via code later. (Problem encountered: I don't know how to set the size of title bar in code. Is it possible? I tried getWindow().setAttributes() and getWindow().setLayout() but both of them didn't worked.)" In XML: <item name="android:windowTitleSize">30dp</item> Modify windowTitleBackgroundStyle and set a transparent drawable as background. (Problem encountered: The content of the title bar became invisible but a line below the title bar is still visible.) In XML: <!-- style used by windowTitleBackgroundStyle --> <item name="android:background">@drawable/transparent</item>

  • Load more function in Javascript

    - by erastusnjuki
    EDIT: This question was initially too general, I think. So What I really need is a very good tutorial on how to implement the Load More function on Safari for iPhone just like the Twitter website(mobile.twitter.com) does. Just a wordpress plugin won't really help. But if the plugin is well explained, like if it is wptouch, home(that also has this function) that can also do. I know that it doesn't really matter that it is being displayed on a mobile device, but the point I am stressing is that if such a function is well explained, then it will be up to me to know how to customize it to suit me. I am using a javascript function to load entries that come from the database dynamically, so that content opens in the same page (like with twitter(tweets feed) and facebook(news feed)). The php/html version(That opens a page in a new tab) is echo '<a href="http://'. $_SERVER['HTTP_HOST'] .'/'.$domain_page.'?form='.$form_id.'&page='.($page+1).'">Load more entries&rsaquo; </a>'; The javascript/ajax version: <div id="call_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>" class="ajax-load-more"> <img id="spinner<?php echo md5($_SERVER['REQUEST_URI']); ?>" class="spin" src="<?php bloginfo('template_directory'); ?>/images/main-ajax-loader.gif" style="display:none" alt="" /> <a class="ajax" href="javascript:$ajax_hv('#spinner<?php echo md5($_SERVER['REQUEST_URI']); ?>').fadeIn(200); $ajax_hv('#ajaxentries_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>').load('form='<? echo $form_id; ?>&page=<?php echo $page+1;?>', {}, function(){ $ajax_hv('#call_hv<?php echo md5($_SERVER['REQUEST_URI']); ?>').fadeOut();})">Load more entries... </a>
