  • jquery window.unload triggers post after unload

    - by index
    I am trying to do a post to server before unloading a page and I followed this and it's working fine. My problem is the $.post on window.unload is triggered after it has unloaded. I tried it with a signout link and checking on my logs, I get the following: Started GET "/signout" for 127.0.0.1 at 2012-11-22 00:15:08 +0800 Processing by SessionsController#destroy as HTML Redirected to http://localhost:3000/ Completed 302 Found in 1ms Started GET "/" for 127.0.0.1 at 2012-11-22 00:15:08 +0800 Processing by HomeController#index as HTML Rendered home/index.html.erb within layouts/application (0.4ms) Rendered layouts/_messages.html.erb (0.1ms) Completed 200 OK in 13ms (Views: 12.9ms) Started POST "/unloading" for 127.0.0.1 at 2012-11-22 00:15:08 +0800 Processing by HomeController#unloading as */* Parameters: {"p1"=>"1"} WARNING: Can't verify CSRF token authenticity Completed 500 Internal Server Error in 0ms NoMethodError (undefined method `id' for nil:NilClass): app/controllers/home_controller.rb:43:in `unloading' First part is the signout and then user gets redirected to root then it runs the post ('/unloading'). Is there a way to make the '/unloading' execute first then execute whatever the unload action was? I have this as my jquery post $(window).unload -> $.ajax { async: false, beforeSend: (xhr) -> xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content')) , url: '/unloading' , type: 'Post' , data: { p1: '1' } }

  • Having trouble comparing a range of dates entered in a form with records in a mySQL database

    - by Andrew Fox
    I have a table called schedule and a column called Date where the column type is date. In that column I have a range of dates, which is currently from 2012-11-01 to 2012-11-30. I have a small form where the user can enter a range of dates (input names from and to) and I want to be able to compare the range of dates with the dates currently in the database. This is what I have: //////////////////////////////////////////////////////// //////First set the date range that we want to use////// //////////////////////////////////////////////////////// if(isset($_POST['from']) && ($_POST['from'] != NULL)) { $startDate = $_POST['from']; } else { //Default date is Today $startDate = date("Y-m-d"); } if(isset($_POST['to']) && ($_POST['to'] != NULL)) { $endDate = $_POST['to']; } else { //Default day is one month from today $endDate = date("Y-m-d", strtotime("+1 month")); } ////////////////////////////////////////////////////////////////////////////////////// //////Next calculate the total amount of days selected above to use as a limiter////// ////////////////////////////////////////////////////////////////////////////////////// $dayStart = strtotime($startDate); $dayEnd = strtotime($endDate); $total_days = abs($dayEnd - $dayStart) / 86400 +1; echo "Start Date: " . $startDate . "<br>End Date: " . $endDate . "<br>"; echo "Day Start: " . $dayStart . "<br>Day End: " . $dayEnd . "<br>"; echo "Total Days: " . $total_days . "<br>"; //////////////////////////////////////////////////////////////////////////////////// //////Then we're going to see if the dates selected are in the schedule table////// //////////////////////////////////////////////////////////////////////////////////// //Select all of the dates currently in the schedule table between the range selected. $sql = ("SELECT Date FROM schedule WHERE Date BETWEEN '$startDate' AND '$endDate' LIMIT $total_days"); //Run a check on the query to make sure it worked. If it failed then print the error. if(!$result_date_query = $mysqli->query($sql)) { die('There was an error getting the dates from the schedule table [' . $mysqli->error . ']'); } //Set the dates to an array for future use. // $current_dates = $result_date_query->fetch_assoc(); //Loop through the results while a result is being returned. while($row = $result_date_query->fetch_assoc()) { echo "Row: " . $row['Date'] . "<br>"; echo "Start day: " . date('Y-m-d', $dayStart) . "<br>"; //Set this loop to add 1 day to the Start Date until it reaches the End Date for($i = $dayStart; $i <= $dayEnd; $i = strtotime('+1 day', $i)) { $date = date('Y-m-d',$i); echo "Loop Start day: " . date('Y-m-d', $dayStart) . "<br>"; //Run a check to see if any of the dates selected are in the schedule table. if($row['Date'] != $date) { echo "Current Date: " . $row['Date'] . "<br>"; echo "Date: " . $date . "<br>"; echo "It appears as though you've selected some dates that are not in the schedule database.<br>Please correct the issue and try again."; return; } } } //Free the result so something else can use it. $result_date_query->free(); As you can see I've added in some echo statements so I can see what is being produced. From what I can see it looks like my $row['Date'] is not incrementing and staying at the same date. I originally had it set to a variable (currently commented out) but I thought that could be causing problems. I have created the table with dates ranging from 2012-11-01 to 2012-11-15 for testing and entered all of this php code onto phpfiddle.org but I can't get the username provided to connect. Here is the link: PHP Fiddle I'll be reading through the documentation to try and figure out the user connection problem in the meantime, I would really appreciate any direction or advice you can give me.

  • Extra < using auto complete in Sublime Text 2

    - by ReLeaf
    I installed the All Autocomplete package in my Sublime Text 2 editor and everything works fine except when I type "<div" or something similar, the auto-complete box pops up, I select the one I want and hit enter and it adds "<<div></div>" with an extra "<" in the front of my tag. I have to go back and delete the extra "<" every time...(!) I can't seem to resolve this issue. If I use the command CTRL+Space, the box pops up and I can select the tag I want and it does not include the extra tag but that messes with my flow. Has anyone out there experienced this? Thanks for your help!

  • Implementing a State Machine in Angular.js to control routing

    - by ldn_tech_exec
    Can anyone help me with integrating a state machine to control routing? What's the best method to do this? Create a service? I need to basically intercept every $location request, run the state machine and let it figure out what the next $location.path should be. Think of the problem like a bank of questions that get added and removed over time. The user visits once in a while, passes in the user's answers object to the statemachine, and the statemachine figures out which question to load. This is my pseudocode, but i need to figure out where to put this or what event I can hook into to make sure all route requests are passed through the machine. Do I need a specific stateMachine controller? Do I create a service? Where do I use the service? Do I need to override $locationProvider? $scope.user.answers = [{ id: 32, answer: "whatever" }, { id:33, answer: "another answer" }] $scope.questions = [{ id:32, question:"what is your name?", path:"/question/1" },{ id:34, question:"how old are you?", path:"/question/2" }] var questions = $scope.questions; angular.forEach(questions, function(question) { if(question.id !exist in $scope.user.answers.id) { $location.path = question.path break; }); Thanks

  • Apache FOP - Table top and bottom borders missing pagebreak inside table

    - by Thomas
    I am using Apache FOP to generate a PDF from a XLS FO document. I have created a test XLS FO document that contains a table with collapsed borders that with several tall rows. One of the rows starts on one page and ends on the next and this works as expected. The problem is that the bottom border of the table on the first page is missing and the top border of the table on the second pages is also missing. Below is the sample XLS FO document. <?xml version="1.0" encoding="utf-8"?> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <!-- defines the layout master --> <fo:layout-master-set> <fo:simple-page-master master-name="first" page-height="29.7cm" page-width="21cm" margin-top="1cm" margin-bottom="2cm" margin-left="2.5cm" margin-right="2.5cm"> <fo:region-body margin-top="3cm"/> <fo:region-before extent="3cm"/> <fo:region-after extent="1.5cm"/> </fo:simple-page-master> </fo:layout-master-set> <!-- starts actual layout --> <fo:page-sequence master-reference="first"> <fo:title>Sample Doc</fo:title> <fo:flow flow-name="xsl-region-body" font-size="x-small" font="Times New Roman"> <!-- table start --> <fo:table table-layout="fixed" width="100%" border-collapse="collapse"> <fo:table-column column-width="35mm"/> <fo:table-column column-width="100mm"/> <fo:table-column column-width="20mm"/> <fo:table-body> <fo:table-row> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Column 1</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Columns 2</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Column 3</fo:block> </fo:table-cell> </fo:table-row> <fo:table-row> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Row 1</fo:block> </fo:table-cell> <fo:table-cell border-width="0.5mm" border-style="solid"> <fo:block>Lorem Ipsum is simply dummy text of the printing and typesetting industry.

  • ASP.NET, C#: timeout when trying to Transaction.Commit() to database; potential deadlock?

    - by user1843921
    I have a web page that has coding structured somewhat as follows: SqlConnection conX =new SqlConnection(blablabla); conX.Open(); SqlTransaction tran=conX.BeginTransaction(); try{ SqlCommand cmdInsert =new SqlCommand("INSERT INTO Table1(ColX,ColY) VALUES @x,@y",conX); cmdInsert.Transaction=tran; cmdInsert.ExecuteNonQuery(); SqlCommand cmdSelect=new SqlCOmmand("SELECT * FROM Table1",conX); cmdSelect.Transaction=tran; SqlDataReader dtr=cmdSelect.ExecuteReader(); //read stuff from dtr dtr.Close(); cmdInsert=new SqlCommand("UPDATE Table2 set ColA=@a",conX); cmdInsert.Transaction=tran; cmdInsert.ExecuteNonQuery(); //display MiscMessage tran.Commit(); //display SuccessMessage } catch(Exception x) { tran.Rollback(); //display x.Message } finally { conX.Close(); } So, everything seems to work until MiscMessage. Then, after a while (maybe 15-ish seconds?) x.Message pops up, saying that: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." So something wrong with my trans.Commit()? The database is not updated so I assume the trans.Rollback works... I have read that deadlocks can cause timeouts...is this problem cause by my SELECT statement selecting from Table1, which is being used by the first INSERT statement? If so, what should I do? If that ain't the problem, what is?

  • php calling classes functions in separate pages

    - by sys_debug
    I've worked with J2EE recently and like the idea of struts.xml where I can handle the redirection to pages based on return string from action classes. In PHP, in my new under-development site, I am trying to follow the MVC standards without an MVC framework used from the internet. So I create the controllers, models and views (empty now). The only thing I am really stuck at is when I submit the form in view (insert_product.php) then I will need to create another php page to handle the post data and pass them to controllers. Anyway of avoiding creating those pages and maybe having something like struts.xml? Even if I can post data directly to controller class, that would be good. Thanks,

  • How can I get the data from an ajax request to appear inside a div?

    - by Aaron Brokmeier
    I am unable to get the data from my ajax request to appear inside <div class="l_p_i_c_w"></div>. What am I doing wrong? I know the function inside my_file.php works, because if I refresh the page, then the data shows up where it should. jQuery: $.ajax({ type: "POST", url: "my_file.php", dataType: 'html', success: function(data){ $('div#myID div.l_p_c div.l_p_i_c_w').prepend(data); } }); HTML: <div class="l_p_w" id="myID"> <div class="l_p_c"> <div class="l_p_i_c_w"> <!-- stuff, or may be empty.

  • assigning selected="selected" to dynamic option list

    - by leemjac
    In an "edit article" page i have a select list which displays author first and last name, as well as authorId as the value. As well as the article context and headline and so on (fetched with a different method) - though this method also holds the authorId of the specific article. I need to have the Author of the Article selected in the option list, instead of it defaulting to the first option in the select list. what i have: echo''; //loop through author names in option list $authors_name foreach($authors_name as $nameRow){ echo'<option class="authorId" value = "' . $nameRow['AuthorID'] . '">'. $nameRow['FirstName'].' '.$nameRow['LastName'] .''; } echo'</select>'; and the jquery: var currID = ('#selectAuthor').val(); if(('.authorId').val() == currID){ $('.authorId').addClass('new_class') $('.new_class').prop('selected',true); } OR var currID = ('#selectAuthor').val(); if($("select option[value=currID]").attr('selected','selected')); Any help would be greatly appreciated, I hope what I am trying to do is clear. Thanks in advance I have simplified it with just regular input and checked it in jsfiddle.net here is the HTML '; <option value = "2">Name val 2</option> <option value = "5">Name val 5</option> <option value = "1">Name val 1</option> and here is the jquery var currID = $('#selectAuthor').val(); if($("select option[value='+currID+']").prop('selected',true));? and even then it doesn't apply selected="selected" to option with value="1"

  • Windows RT Powershell (PermissionDenied) on New-Object

    - by bazile
    I am trying to instantiate an object in Powershell for Windows RT, but keep getting the following error. PS > $foo = New-Object System.Security.Cryptography.SHA1Managed New-Object : Cannot create type. Only core types are supported in this language mode. At line:1 char:8 + $foo = New-Object System.Security.Cryptography.SHA1Managed + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : PermissionDenied: (:) [New-Object], PSNotSupportedException + FullyQualifiedErrorId : CannotCreateTypeConstrainedLanguage,Microsoft.PowerShell.Commands.NewObjectCommand I just spent the last thirty minutes engaged in some pretty heavy Google-fu and was unable to find anything even close to a similar problem, let alone an answer. My hope is that I just need to configure something; my fear is that Windows RT ships with a crippled version of Powershell. Does anyone know which case it is?

The class has methods to add integers to a set or remove integers from a set,check size of a set, and check if 2 sets are equal. the 2 sets are created using 2 different objects of type IntArray in main, lets say object A and B. equals method supposed to check if two sets of integers are equal. for example set A = {1,2,3} and B = {1,2,3,4}. The method still return true even though one set is a subset of the other set. What exactly I am doing wrong? Thanks. //part of the code in main IntArray A = new IntArray(); IntArray B = new IntArray(); if(A.equals(B)) System.out.println("A and B are equal"); //equals method in IntArray class public boolean equals(Object b) { if (b instanceof IntArray) { IntArray A = (IntArray) b; for (int i = 0; i < data.length; i++) if (countOccurrences(data[i]) != A.countOccurrences(data[i])) return false; return true; } else return false; }

  • Convert NSData into Hex NSString

    - by Dawson
    With reference to the following question: Convert NSData into HEX NSSString I have solved the problem using the solution provided by Erik Aigner which is: NSData *data = ...; NSUInteger capacity = [data length] * 2; NSMutableString *stringBuffer = [NSMutableString stringWithCapacity:capacity]; const unsigned char *dataBuffer = [data bytes]; NSInteger i; for (i=0; i<[data length]; ++i) { [stringBuffer appendFormat:@"%02X", (NSUInteger)dataBuffer[i]]; } However, there is one small problem in that if there are extra zeros at the back, the string value would be different. For eg. if the hexa data is of a string @"3700000000000000", when converted using a scanner to integer: unsigned result = 0; NSScanner *scanner = [NSScanner scannerWithString:stringBuffer]; [scanner scanHexInt:&result]; NSLog(@"INTEGER: %u",result); The result would be 4294967295, which is incorrect. Shouldn't it be 55 as only the hexa 37 is taken? So how do I get rid of the zeros? EDIT: (In response to CRD) Hi, thanks for clarifying my doubts. So what you're doing is to actually read the 64-bit integer directly from a byte pointer right? However I have another question. How do you actually cast NSData to a byte pointer? To make it easier for you to understand, I'll explain what I did originally. Firstly, what I did was to display the data of the file which I have (data is in hexadecimal) NSData *file = [NSData dataWithContentsOfFile:@"file path here"]; NSLog(@"Patch File: %@",file); Output: Next, what I did was to read and offset the first 8 bytes of the file and convert them into a string. // 0-8 bytes [file seekToFileOffset:0]; NSData *b = [file readDataOfLength:8]; NSUInteger capacity = [b length] * 2; NSMutableString *stringBuffer = [NSMutableString stringWithCapacity:capacity]; const unsigned char *dataBuffer = [b bytes]; NSInteger i; for (i=0; i<[b length]; ++i) { [stringBuffer appendFormat:@"%02X", (NSUInteger)dataBuffer[i]]; } NSLog(@"0-8 bytes HEXADECIMAL: %@",stringBuffer); As you can see, 0x3700000000000000 is the next 8 bytes. The only changes I would have to make to access the next 8 bytes would be to change the value of SeekFileToOffset to 8, so as to access the next 8 bytes of data. All in all, the solution you gave me is useful, however it would not be practical to enter the hexadecimal values manually. If formatting the bytes as a string and then parsing them is not the way to do it, then how do I access the first 8 bytes of the data directly and cast them into a byte pointer?

  • Replacing innertext of XML node using PHP DOMDocument

    - by Rohan Kumar
    I want to replace innertext of a XML node my XML file named test.xml is <?xml version="1.0" encoding="utf-8"?> <ads> <loop>no</loop> <item> <description>Description 1</description> </item> <item> <description>Text in item2</description> </item> <item> <description>Let play with this XML</description> </item> </ads> I want to change the value of loop and description tag both, and it should be saved in test.xml like: <?xml version="1.0" encoding="utf-8"?> <ads> <loop>yes</loop> <item> <description>Description Changing Here</description> </item> <item> <description>Changing text in item2</description> </item> <item> <description>We will play later</description> </item> </ads> I tried code in PHP: <? $file = "test.xml"; $fp = fopen($file, "rb") or die("cannot open file"); $str = fread($fp, filesize($file)); $dom=new DOMDocument(); $dom->formatOutput = true; $dom->preserveWhiteSpace = false; $dom->loadXML($str) or die("Error"); //$dom->load("items.xml"); $root=$dom->documentElement; // This can differ (I am not sure, it can be only documentElement or documentElement->firstChild or only firstChild) $loop=$root->getElementsByTagName('loop')->item(0);//->textContent; //echo $loop; if(trim($loop->textContent)=='no') { echo 'ok'; $root->getElementsByTagName('loop')->item(0)->nodeValue ='yes'; } echo "<xmp>NEW:\n". $dom->saveXML() ."</xmp>"; ?> I tried only for loop tag.I don't know how to replace nodevalue in description tag. When I run this page it shows output like: ok NEW: <?xml version="1.0" encoding="utf-8"?> <ads> <loop>yes</loop> <item> <description>Description 1</description> </item> <item> <description>Changing text in item2</description> </item> <item> <description>Let play with this XML</description> </item> </ads> It gives the value yes in browser but don't save it in test.xml any reason?

  • Installing Ruby On Rails - Issues with gem (and no RVM)

    - by JXPheonix
    I'm having this issue whenever i run "gem install rails": usr/local/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>': It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. ERROR: Loading command: install (LoadError) cannot load such file -- zlib ERROR: While executing gem ... (NameError) uninitialized constant Gem::Commands::InstallCommand Ruby and Rubygems were both installed from source. I've installed libyaml from source and from apt-get. I'm running ubuntu 12.04. I am NOT running RVM as far as I know (trying "rvm" returns "bla bla bla not installed apt-get". I'm pretty sure this speaks of 2 separate issues but I need solutions to both. Thanks.

  • a reddit-php-sdk method not outputting anything

    - by diggpthoo
    I'm trying to learn reddit code and using this https://github.com/jcleblanc/reddit-php-sdk There's a method in this library $reddit->getUser() which outputs null always. Everything else seems to be working though. include_once("jcleblanc-reddit-php-sdk-4a4cc32/reddit.php"); $reddit = new reddit("my-username", "my-password"); $userData = $reddit->getUser(); var_dump($userData); outputs null. $response = $reddit->getListing("all", 5); var_dump($response); outputs what's expected just fine. Then what could be going wrong with $reddit->getUser()?

  • What is better for a student programming in C++ to learn for writing GUI: C# vs QT?

    - by flashnik
    I'm a teacher(instructor) of CS in the university. The course is based on Cormen and Knuth and students program algorithms in C++. But sometimes it is good to show how an algorithm works or just a result of task through GUI. Also in my opinion it's very imporant to be able to write full programs. They will have courses concerning GUI but a three years, later, in fact, before graduatuion. I think that they should be able to write simple GUI applications earlier. So I want to teach them it. How do you think, what is more useful for them to learn: programming GUI with QT or writing GUI in C# and calling unmanaged C++ library? Update. For developing C++ applications students use MS Visual studio, so C# is already installed. But QT AFAIK also can be integrated into VS. I have following pros of C# (some were suggested there in answers): The need to make an additional layer. It's more work, but it forces you explicitly specify contract between GUI and processing data. The border between GUI and algorithms becomes very clear. It's more popular among employers. At least, in Russia where we live. It's rather common to write performance-critical algorithms in C++ and PInvoke them from well-looking C# application/ASP.Net website. Maybe it is not so widespread in the rest of the world but in Russia Windows is very popular, especially in companies and corporations due to some reasons, so most of b2b applications are Windows applications. Rapid development. It's much quicker to code in .Net then in C++ due to many reasons. And the con is that it's a new language with own specific for students. And the mess with invoking calls to library.

  • Is JDEE worth using?

    - by User1
    I see many nice feature of JDEE in Emacs. However installation seems to be a bit involved, especially in Windows so I want to see if others found it useful. I use Eclipse and NetBeans and there are some decent features to these products. However, I really like the idea of a scripted language like Lisp built into my IDE so I can change most features on-the-fly. So I want to give JDEE a shot, but I've heard from more than one advanced Emacs user that they don't even need JDEE. I wonder if those people even tried JDEE or if they are just doing simple Java projects. Has anyone tried JDEE and liked it? Are there features in Emacs that make JDEE fairly pointless? Please no "try Eclipse" comments..I have used it and it has nice features, but I want to give Emacs a fair shot. UPDATE: See my accepted answer. I tried JDEE for a while but gave it up for eclipse and have never looked back. Happily ever after.

  • A Simple Entity Tagger

    - by Elton Stoneman
    In the REST world, ETags are your gateway to performance boosts by letting clients cache responses. In the non-REST world, you may also want to add an ETag to an entity definition inside a traditional service contract – think of a scenario where a consumer persists its own representation of your entity, and wants to keep it in sync. Rather than load every entity by ID and check for changes, the consumer can send in a set of linked IDs and ETags, and you can return only the entities where the current ETag is different from the consumer’s version.  If your entity is a projection from various sources, you may not have a persistent ETag, so you need an efficient way to generate an ETag which is deterministic, so an entity with the same state always generates the same ETag. I have an implementation for a generic ETag generator on GitHub here: EntityTagger code sample. The essence is simple - we get the entity, serialize it and build a hash from the serialized value. Any changes to either the state or the structure of the entity will result in a different hash. To use it, just call SetETag, passing your populated object and a Func<> which acts as an accessor to the ETag property: EntityTagger.SetETag(user, x => x.ETag); The implementation is all in at 80 lines of code, which is all pretty straightforward: var eTagProperty = AsPropertyInfo(eTagPropertyAccessor); var originalETag = eTagProperty.GetValue(entity, null); try { ResetETag(entity, eTagPropertyAccessor); string json; var serializer = new DataContractJsonSerializer(entity.GetType()); using (var stream = new MemoryStream()) { serializer.WriteObject(stream, entity); json = Encoding.UTF8.GetString(stream.GetBuffer(), 0, (int)stream.Length); } var guid = GetDeterministicGuid(json); eTagProperty.SetValue(entity, guid.ToString(), null); //... There are a couple of helper methods to check if the object has changed since the ETag value was last set, and to reset the ETag. This implementation uses JSON to do the serializing rather than XML. Benefit - should be marginally more efficient as your hashing a much smaller serialized string; downside, JSON doesn't include namespaces or class names at the root level, so if you have two classes with the exact same structure but different names, then instances which have the same content will have the same ETag. You may want that behaviour, but change to use the XML DataContractSerializer if you think that will be an issue. If you can persist the ETag somewhere, it will save you server processing to load up the entity, but that will only apply to scenarios where you can reliably invalidate your ETag (e.g. if you control all the entry points where entity contents can be updated, then you can calculate and persist the new ETag with each update).
