• FluentMigrator tutorials

  - by Paja

  Are there any tutorials for FluentMigrator? Some "Getting Started..." tutorial would be just awesome. All I was able to find was FluentMigrator.Tests (unit tests), inside FluentMigrator source, which are not as helpful as "Getting Started..." would be.

• Accessing array values in jQuery ajax callback function

  - by gibberish

  Values are received through a jQuery AJAX callback, but I've been unsuccessful getting at the values. Here's the ajax call: $.ajax({ type: "POST", url: "ajax/ax_all_ajax_fns.php", data: 'request=edit_timecard_entry&staff_id='+staff_id+'&tid='+tid, success: function(data){ alert(data); } } Here's the code sent out by ax_all_ajax_fns.php: $staff_id = $_POST['staff_id']; $t_id = $_POST['tid']; $rCard = mysql_query("SELECT `staff_id`, `date`, `project_id`, `project_num`, `task_desc`, `hours` FROM `timecards` WHERE `t_id`='$t_id'"); $aCard = mysql_fetch_assoc($rCard); print_r($aCard); // echo $aCard; Of course, I don't want the information print_r'd, I want it echoed. The print_r was used to demonstrate that the correct data was sent out by the PHP script, and it is echoed successfully in the alert() box in the success function. So the correct data is being returned, and (if correctly formatted) it is viewable. The data returned in this way looks like this in the alert() popup: Array ( [staff_id] => 51 [date] => 2012-10-18 [project_id] => 0 [project_num => 49 [task_desk] => This is a task [hours] => 3.30 ) But when I use echo to output the $aCard array and then try to break it down inside the success function of the ajax call, I can't figure out how to get at the values. My attempts have consistently returned values of "undefined". In the success function, in place of alert(data);, I've tried this: var tce_staff_id = data['staff_id']; alert(tce_staff_id); and this: var tce_staff_id = data.staff_id; alert(tce_staff_id); What am I missing? UPDATE: Thanks to Martin S. for information re json_encode() PHP instruction. I've modified the ajax script as follows: echo json_encode($aCard); I now get THIS result from alert(data); in the success function: {"staff_id":"51","date":"2012-10-18","project_id":"0","project_num":"49","task_desc":"This is a task","hours":"3.30"} However, the following returns "undefined": alert(data.staff_id); alert(data[0].staff_id); var test = data.staff_id; alert(test); Can anyone see what I'm missing? All above code comes immediately after alert(data) inside the success callback of the ajax function. alert(data) DOES work and displays the desired data, as above.

  - by Ward

  Hey there, I have a UINavigationController inside a UITabBarController. When a user presses the first tab, I want to reset the navigation controller back to the first screen instead of displaying whichever view they last selected in the navigation controller. Is there an easy way to reset the stack? Thanks, Howie

• Ajax problem not displaying data using multiple javascript calls...

  - by Ronedog

  I'm writing an app that uses ajax to retrieve data from a mysql db using php. Because of the nature of the app, the user clicks an href link that has an "onclick" event used to call the javascript/ajax. I'm retrieving the data from mysql, then calling a separate php function which creates a small html table with the necessary data in it. The new table gets passed back to the responseText and is displayed inside a div tag. The tables only have around 10-20 rows of data in them. This functionality is working fine and displays the data in html form exactly as it needs to be on the page. The problem is this. the HREF "onclick" event needs to run multiple scripts one right after the other. The first script updates the "existing" data and inside the "update_existing" function is a call to refresh a section of the page with the updated HTML from the responseText. Then when that is done a "display_html" function is called which also updates a different section of the page with it's newly created HTML table. The event looks like this: Update This string gets built dynamically using php with parameters supplied, but for this example I simply took the parameters out so it didn't get confusing. The "update_existion() function actually calls the display_html() function which updates a section of the page as needed. I need to update a different section of the page on the same click of the mouse right after the update, which is why I'm calling the display_html() again, right after it. The problem is only the last call is being updated on my screen. In other words, the 2nd function call "display_html()" executes and displays the refreshed data just fine, but the previous call to update_existing() runs and updates the database properly, but doesn't display on the screen unless I press the browsers "refresh" button, which of course displays the new data exactly how I want it to, but I don't want the users to have to press the "refresh" button. I tried adding multiple "display_html() calls one right after the other, separating all of them with the semicolon and learned that only the very last function call actually refreshed the div element on the html page with the table information, although all the previous display_html() calls worked, they couldn't be seen on the page without a refresh of the browser. Is this a problem with javascript, or the ajax call, or is this a limitation in the DOM that only allows one element to be updated at a time. The ajax call is asynchroneous, but I've tried both, only async works period. This is the same in both Firefox and Internet Explorer Any ideas what's going on and how to get around it so I can run these multiple scripts?

• Is it possible top opt-out of INamingContainer if it's implemented by a superclass?

  - by michielvoo

  The UserControl class inherits from TemplateControl which implements INamingContainer. Since this is "only a marker interface" I was wondering if it's possible to opt-out of the behavior that this interface brings with it. I am developing a templated control based on a user control, and I want the controls inside the template to be accessible in the page without using FindControl(id).

• SVN Repository folders don't match my solution folder structure in Visual Studio or folder structure

  - by Carlos

  I have a .NET solution which was badly organised, so I moved some projects around to appropriate folders. In the solution, I simply fixed the paths to the new locations, and everything is working in my working copy. I used AnkhSVN to commit the solution to the repository, which worked out fine as well. However, when I look in the repo explorer, the folders inside are organised in the old way. What do I need to do?

• Algorithm to merge adjacent rectangles into polygon

  - by Glitch

  I guess that my problem is related to "convex hull", but no the same. All shapes in the drawing are rectangles with same width and height. Many are adjacent to each other. I want to combine those adjacent rectangles into polygons. Unlike "convex hull", the resuled polygons could be "hollow" inside. Is there any open source algorithm available?

• jQuery "Autocomplete" plugin is messing up the order of my data

  - by Max Williams

  I'm using Jorn Zaefferer's Autocomplete plugin on a couple of different pages. In both instances, the order of displayed strings is a little bit messed up. Example 1: array of strings: basically they are in alphabetical order except for General Knowledge which has been pushed to the top: General Knowledge,Art and Design,Business Studies,Citizenship,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Displayed strings: General Knowledge,Geography,Art and Design,Business Studies,Citizenship,Design and Technology,English,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Note that Geography has been pushed to be the second item, after General Knowledge. The rest are all fine. Example 2: array of strings: as above but with Cross-curricular instead of General Knowledge. Cross-curricular,Art and Design,Business Studies,Citizenship,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Displayed strings: Cross-curricular,Citizenship,Art and Design,Business Studies,Design and Technology,English,Geography,History,ICT,Mathematics,MFL French,MFL German,MFL Spanish,Music,Physical Education,PSHE,Religious Education,Science,Something Else Here, Citizenship has been pushed to the number 2 position. I've experimented a little, and it seems like there's a bug saying "put things that start with the same letter as the first item after the first item and leave the rest alone". Kind of mystifying. I've tried a bit of debugging by triggering alerts inside the autocomplete plugin code but everywhere i can see, it's using the correct order. it seems to be just when its rendered out that it goes wrong. Any ideas anyone? max EDIT - reply to Clint Thanks for pointing me at the relevant bit of code btw. To make diagnosis simpler i changed the array of values to ["carrot", "apple", "cherry"], which autocomplete re-orders to ["carrot", "cherry", "apple"]. Here's the array that it generates for stMatchSets: stMatchSets = ({'':[#1={value:"carrot", data:["carrot"], result:"carrot"}, #3={value:"apple", data:["apple"], result:"apple"}, #2={value:"cherry", data:["cherry"], result:"cherry"}], c:[#1#, #2#], a:[#3#]}) So, it's collecting the first letters together into a map, which makes sense as a first-pass matching strategy. What i'd like it to do though, is to use the given array of values, rather than the map, when it comes to populating the displayed list. I can't quite get my head around what's going on with the cache inside the guts of the code (i'm not very experienced with javascript).

• ASP.Net JSON Web Service Post Form Data

  - by Will D

  I have a ASP.NET web service decorated with System.Web.Script.Services.ScriptService() so it can return json formatted data. This much is working for me, but ASP.Net has a requirement that parameters to the web service must be in json in order to get json out. I'm using jquery to run my ajax calls and there doesn't seem to be an easy way to create a nice javascript object from the form elements. I have looked at serialiseArray in the json2 library but it doesn't encode the field names as property name in the object. If you have 2 form elements like this <input type="text" name="namefirst" id="namefirst" value="John"/> <input type="text" name="namelast" id="namelast" value="Doe"/> calling $("form").serialize() will get you the standard query string namefirst=John&namelast=Doe calling JSON.stringify($("form").serializeArray()) will get you the (bulky) json representation [{"name":"namefirst","value":"John"},{"name":"namelast","value":"Doe"}] This will work when passing to the web service but its ugly as you have to have code like this to read it in: Public Class NameValuePair Public name As String Public value As String End Class <WebMethod()> _ Public Function GetQuote(ByVal nvp As NameValuePair()) As String End Function You would also have to wrap that json text inside another object nameed nvp to make the web service happy. Then its more work as all you have is an array of NameValuePair when you want an associative array. I might be kidding myself but i imagined something more elegant when i started this project - more like this Public Class Person Public namefirst As String Public namelast As String End Class which would require the json to look something like this: {"namefirst":"John","namelast":"Doe"} Is there an easy way to do this? Obviously it is simple for a form with two parameters but when you have a very large form concatenating strings gets ugly. Having nested objects would also complicate things The cludge I have settled on for the moment is to use the standard name value pair format stuffed inside a json object. This is compact and fast {"q":"namefirst=John&namelast=Doe"} then have a web method like this on the server that parses the query string into an associate array. <WebMethod()> _ Public Function AjaxForm(ByVal q As String) as string Dim params As NameValueCollection = HttpUtility.ParseQueryString(q) 'do stuff return "Hello" End Sub As far a cludges go this one seems reasonably elegant in terms of amount of code, but my question is: is there a better way? Is there a generally accepted way of passing form data to asp.net web/script services?

• How can I inject Javascript (including Prototype.js) in other sites without cluttering the global na

  - by Daniel Magliola

  I'm currently on a project that is a big site that uses the Prototype library, and there is already a humongous amount of Javascript code. We're now working on a piece of code that will get "injected" into other people's sites (picture people adding a <script> tag in their sites) which will then run our code and add a bunch of DOM elements and functionality to their site. This will have new pieces of code, and will also reuse a lot of the code that we use on our main site. The problem I have is that it's of course not cool to just add a <script> that will include Prototype in people's pages. If we do that in a page that's already using ANY framework, we're guaranteed to screw everything up. jQuery gives us the option to "rename" the $ object, so it could handle this situation decently, except obviously for the fact that we're not using jQuery, so we'd have to migrate everything. Right now i'm contemplating a number of ugly choices, and I'm not sure what's best... Rewrite everything to use jQuery, with a renamed $ object everywhere. Creating a "new" Prototype library with only the subset we'd be using in "injected" code, and renaming $ to something else. Then again I'd have to adapt the parts of my code that would be shared somehow. Not using a library at all in injected code, to keep it as clean as possible, and rewriting the shared code to use no library at all. This would obviously degenerate into us creating our own frankenstein of a library, which is probably the worst case scenario ever. I'm wondering what you guys think I could do, and also whether there's some magic option that would solve all my problems... For example, do you think I could use something like Caja / Cajita to sandbox my own code and isolate it from the rest of the site, and have Prototype inside of there? Or am I completely missing the point with that? I also read once about a technique for bookmarklets, were you add your code like this: (function() { /* your code */ })(); And then your code is all inside your anonymous function and you haven't touched the global namespace at all. Do you think I could make one file containing: (function() { /* Full Code of the Prototype file here */ /* All my code that will run in the "other" site */ InitializeStuff_CreateDOMElements_AttachEventHandlers(); })(); Would that work? Would it accomplish the objective of not cluttering the global namespace, and not killing the functionality on a site that uses jQuery, for example? Or is Prototype too complex somehow to isolate it like that? (NOTE: I think I know that that would create closures everywhere and that's slower, but I don't care too much about performance, my code is not doing anything that complex)
