• Treebeard admin in Django

  - by Sharath

  I've setup Treebeard in Django and everything seems to have gone well. I tried to setup the admin system and I can see my models being presented in the admin interface. However, when I try to add new data using the admin interface, I get the following error in my template. The code still works fine, and I did a check in my DB and the data seems to be inserted properly. However, the view doesn't seem to load properly. Any idea about what is causing this?? The exception am getting is.. Caught an exception while rendering: Failed lookup for key [request] in u'[{\'action_index\': 0, \'block\': , , , , , , ]}, {\'block\': , , , ], , , , , \n \', ], , ], , , , ], , , \n \', , , , , , , , , ], , ], \n \']}, {\'cl\': , \'root_path\': None, \'actions_on_bottom\': False, \'title\': u\'Select album to change\', \'has_add_permission\': True, \'media\': , \'is_popup\': False, \'action_form\': , \'actions_on_top\': True, \'app_label\': \'gallery\'}, {\'MEDIA_URL\': \'\'}, {\'LANGUAGES\': ((\'ar\', \'Arabic\'), (\'bn\', \'Bengali\'), (\'bg\', \'Bulgarian\'), (\'ca\', \'Catalan\'), (\'cs\', \'Czech\'), (\'cy\', \'Welsh\'), (\'da\', \'Danish\'), (\'de\', \'German\'), (\'el\', \'Greek\'), (\'en\', \'English\'), (\'es\', \'Spanish\'), (\'et\', \'Estonian\'), (\'es-ar\', \'Argentinean Spanish\'), (\'eu\', \'Basque\'), (\'fa\', \'Persian\'), (\'fi\', \'Finnish\'), (\'fr\', \'French\'), (\'ga\', \'Irish\'), (\'gl\', \'Galician\'), (\'hu\', \'Hungarian\'), (\'he\', \'Hebrew\'), (\'hi\', \'Hindi\'), (\'hr\', \'Croatian\'), (\'is\', \'Icelandic\'), (\'it\', \'Italian\'), (\'ja\', \'Japanese\'), (\'ka\', \'Georgian\'), (\'ko\', \'Korean\'), (\'km\', \'Khmer\'), (\'kn\', \'Kannada\'), (\'lv\', \'Latvian\'), (\'lt\', \'Lithuanian\'), (\'mk\', \'Macedonian\'), (\'nl\', \'Dutch\'), (\'no\', \'Norwegian\'), (\'pl\', \'Polish\'), (\'pt\', \'Portuguese\'), (\'pt-br\', \'Brazilian Portuguese\'), (\'ro\', \'Romanian\'), (\'ru\', \'Russian\'), (\'sk\', \'Slovak\'), (\'sl\', \'Slovenian\'), (\'sr\', \'Serbian\'), (\'sv\', \'Swedish\'), (\'ta\', \'Tamil\'), (\'te\', \'Telugu\'), (\'th\', \'Thai\'), (\'tr\', \'Turkish\'), (\'uk\', \'Ukrainian\'), (\'zh-cn\', \'Simplified Chinese\'), (\'zh-tw\', \'Traditional Chinese\')), \'LANGUAGE_BIDI\': False, \'LANGUAGE_CODE\': \'en-us\'}, {}, {\'perms\': , \'messages\': [], \'user\': }, {}]' This happens after I hit the save button in Django admin. This is my admin.py implementation.. class MP_Album_Admin(TreeAdmin): pass admin.site.register(Album,MP_Album_Admin)

• MooTools Event Delegation using HTML5 data attributes.

  - by Anurag

  Is it possible to have event delegation using the HTML5 data attributes in MooTools? The HTML structure I have is: ?<div id="parent"> <div>not selectable</div> <div data-selectable="true">selectable</div> <div>not selectable either.</div> <div data-selectable="true">also selectable</div> </div>???????????????????????????????????????????????????????????????????????? And I want to setup <div id="parent"> to listen to all clicks only on child elements that have the data-selected attribute. Please let me know if I'm doing something wrong: The events are being setup as: $("parent").addEvent("click:relay([data-selectable])", function(event, el) { alert(this.get('text')); }); but the click callback is fired on clicking all div's, not just the ones with a data-selectable attribute defined. You can see this example on http://jsfiddle.net/NUGD4/ A workaround is to adding this as a CSS class, which works with delegation but I would prefer to be able to use data-attributes as it's used throughout the application.

• JAXB boolean handling oddities and JSF

  - by finrod

  There is a known bug in JAXB: https://jaxb.dev.java.net/issues/show_bug.cgi?id=733 JAXB does not properly generate boolean field getters and setters, this bug is left unfixed for backwards compatibility. A JAXB plugin exists and will ensure that the following getters and setters for boolean fields are generated: setXXX(Boolean value) is generated getXXX() is generated If the boolean attribute specifies default value in the XSD, then getXXX() returns boolean, If the boolean attribute does not specify default in the XSD, then getXXX() returns Boolean. Problem: trying to edit/view the XXX field in a JSF component (such as checkbox) does not work - the component is disabled. I have not traced this in depth but the assumption (backed by the workaround below) is that JSF EL resolver (or whathaveyou) looks for Boolean getXXX() method and since it does not find it, the component is disabled. Workaround: If I change the getXXX() method to always return Boolean, then everything goes. Questions: What are your ideas to address this problem? Have I missed some customization for the boolean-getter JAXB plugin? Is it possible (does it make sense) to alter JSF resolver (or whathaveyou) so that if Boolean getXXX() is not found, it will fall back to boolean getXXX()? I would prefer not to manually intervene and change all the generated getXXX() methods to return Boolean instead of boolean.

• Reading Data from DDFS ValueError: No JSON object could be decoded

  - by secumind

  I'm running dozens of map reduce jobs for a number of different purposes using disco. My data has grown enormous and I thought I would try using DDFS for a change rather than standard txt files. I've followed the DISCO map/reduce example Counting Words as a map/reduce job, without to much difficulty and with the help of others, Reading JSON specific data into DISCO I've gotten past one of my latest problems. I'm trying to read data in/out of ddfs to better chunk and distribute it but am having a bit of trouble. Here's an example file: file.txt {"favorited": false, "in_reply_to_user_id": null, "contributors": null, "truncated": false, "text": "I'll call him back tomorrow I guess", "created_at": "Mon Feb 13 05:34:27 +0000 2012", "retweeted": false, "in_reply_to_status_id_str": null, "coordinates": null, "in_reply_to_user_id_str": null, "entities": {"user_mentions": [], "hashtags": [], "urls": []}, "in_reply_to_status_id": null, "id_str": "168931016843603968", "place": null, "user": {"follow_request_sent": null, "profile_use_background_image": true, "profile_background_image_url_https": "https://si0.twimg.com/profile_background_images/305726905/FASHION-3.png", "verified": false, "profile_image_url_https": "https://si0.twimg.com/profile_images/1818996723/image_normal.jpg", "profile_sidebar_fill_color": "292727", "is_translator": false, "id": 113532729, "profile_text_color": "000000", "followers_count": 78, "protected": false, "location": "With My Niggas In Paris!", "default_profile_image": false, "listed_count": 0, "utc_offset": -21600, "statuses_count": 6733, "description": "Made in CHINA., Educated && Making My Own $$.

• Does anyone knows any Train-table-api service?

  - by DaNieL

  Hi guys, im wondering if there is any online service who provide API about the train timetables (arrivals, departure, etch..), at least for the european stations. I know www.bahn.de, who provide the accurated timetables for many european countries, but i didin't find any similar to a api service. My goal (well, just a future-project) is to develope an application like gmaps, but instead of giving the car-trip i would like to give the train-trip.. you know, the user set the departure day, time and station, then the first arrival, maybe then add another one, and so on. So, there is something like, that can be queryed by php/python/javascript? Edit: if can help, im wondering to build a service to plan an inter-rail trip! (and any help will be really appreciate) Im stuck. Google's public-service api rely on the information that every local company makes avaiable, much branches are missing (for example, is almost impossible to use it to build an itinerary that touches two or more regions of Europe. As i said before, the only service that i know doing it good is the bahn.de, they really have all the data.. but no api. I tryed to parse theyre result page (in order to use them as API), but seem like the markup is been build exactly to avoid that.. maybe they have business plans behind that or whatever, but i dont think they will ever release some API.. so, my project is going on without this function (p.s: my project is about non-profit cultural organizations, we wont make war to anyone ;P) @El Goorf: if you find a way, and consider the idea of sharing it, count on my hand if need help!

• C#, finding the largest prime factor of a number

  - by Juan

  Hello! I am new at programming and I am practicing my C# programming skills. My application is meant to find the largest prime factor of a number entered by the user. But my application is not returning the right answer and I dont really know where the problem is. Can you please help me? using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Console.WriteLine("Calcular máximo factor primo de n.

• XSP2 crashes serving static images

  - by Dawkins

  Hi, Requesting a simple HTML page with a jpg image makes XSP2 crash. If I remove the image from the HTML then the page is served OK all the time. The version is XSP2 2.0 mono 2.6.1. the version 2.4.2.2 in the same machine works fine. I have tested it in two different machines, both Windows Vista Business SP1. Anyone has experienced the same? Any clue of what can be the problem? Below is the stack trace displayed by the console: (The line in Spanish says "it has been forced the interruption of an existing connection by the remote host") EDIT: since another user is having the same problem I have submited a bug to Novell and created a litle zip to reproduce the problem: https://bugzilla.novell.com/show_bug.cgi?id=582162 Peer unexpectedly closed the connection on write.

• Simple Enterprise Library console application refuses to compile

  - by Vadim

  I just downloaded and installed Microsoft Enterprise Library 5.0. I fired up VS 2010 to play with EL 5 and created a very simple console application. However, it would not compile. I got the following error: The type or namespace name 'Data' does not exist in the namespace 'Microsoft.Practices.EnterpriseLibrary' (are you missing an assembly reference?) I added Microsoft.Practices.EnterpriseLibrary.Common, Microsoft.Practices.EnterpriseLibrary.Data, and Microsoft.Practices.Unity references to my project. Here's the simple code that refuses to compile. using Microsoft.Practices.EnterpriseLibrary.Common.Configuration.Unity; using Microsoft.Practices.EnterpriseLibrary.Data; using Microsoft.Practices.Unity; namespace EntLib { class Program { static void Main(string[] args) { IUnityContainer container = new UnityContainer(); container.AddNewExtension<EnterpriseLibraryCoreExtension>(); var defaultDatabase = container.Resolve<Database>(); } } } The error above complains about line #2 : using Microsoft.Practices.EnterpriseLibrary.Data; Someone probably will point out to a stupid mistake by me, but at the moment I fail to see it. I tried to remove and add again Microsoft.Practices.EnterpriseLibrary.Data to refences but it didn't help.

  Hi. I'm fairly new to jQuery. I have a Jquery datepicker in a user control. I have added a "disable" property to the datepicker. Whenever I save the page(having this usercontrol) the datepicker with disable set to true is empty. All other datepickers save fine. Here is my code. ASPX < USERCONTROL:DATEPICKER id="dpBirthDate" startyear="1980" runat="server" Disable=true ASCX < input type="text" size="8" runat="server" id="txtDate" name="txtDate" onblur="ValidateForm(this.id);" / ASCX Code Behind Public Property Disable() As Boolean Get Return (txtDate.Disabled = True) End Get Set(ByVal bValue As Boolean) If (bValue = True) Then txtDate.Attributes.Add("Disabled", "True") Else txtDate.Attributes.Remove("Disabled") End If End Set End Property My Jquery $(document).ready(function() { $("input[id$=txtDate]").datepicker({ showOn: 'button', buttonImage: '<%=ConfigurationSettings.AppSettings("BASE_DIRECTORY")%>/Images/el-calendar.gif', buttonImageOnly: true }); $("input[id$=txtDate]").mask("99/99/9999", { placeholder: " " }); //Disable datepicker if "disable=true" $("input[id$=txtDate]").each(function() { if ($("input[id$=" + this.id + "]").attr("Disabled") == "True") { $("input[id$=" + this.id + "]").datepicker("disable"); } else if ($("input[id$=" + this.id + "]").attr("Disabled") == "False") { $("input[id$=" + this.id + "]").datepicker("enable"); } }); }); I am sorry, I am not sure how to format the code here. I apologies for the cluttered code. Can anybody tell me why the datepicker value is empty when it is disabled but works fine otherwise? Thanks is advance.

• JQuery Validate: only takes the first addMethod?

  - by Neuquino

  Hi, I need to add multiple custom validations to one form. I have 2 definitions of addMethod. But it only takes the first one... here is the code. $(document).ready(function() { $.validator.addMethod("badSelectionB",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_B_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) != 0){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $.validator.addMethod("badSelectionA",function(){ var comboValues = []; for(var i=0;i<6;i++){ var id="comision_A_"+(i+1); var comboValue=document.getElementById(id).value; if($.inArray(comboValue,comboValues) != 0){ comboValues.push(comboValue); }else{ return false; } } return true; },"Seleccione una única prioridad por comisión."); $("#inscripcionForm").validate( { rules : { nombre : "required", apellido : "required", dni : { required: true, digits: true, }, mail : { required : true, email : true, }, comision_A_6: { badSelectionA:true, }, comision_B_6: { badSelectionB: true, } }, messages : { nombre : "Ingrese su nombre.", apellido : "Ingrese su apellido.", dni : { required: "Ingrese su dni.", digits: "Ingrese solo números.", }, mail : { required : "Ingrese su correo electrónico.", email: "El correo electrónico ingresado no es válido." } }, }); }); Do you have any clue of what is happening? Thanks in advance,

• can I disable the "(Type e to repeat macro)" message in emacs?

  - by lindes

  Hi there, So, I've finally made the plunge, and have gotten to the state where I'm quite happy to have switched from vi and vim to emacs... I've been putting stuff in my .emacs file, learning how to evaluate things (not to mention becoming familiar with movement commands), etc. etc. etc. And now I have a problem with a require line in my .emacs file (a require statement*), which bombs out when I launch emacs (and generally fails to work). So, this lead me to the following situation: In the process of trying to debug the above situation, one of the steps I did was to open the file I was trying to require, and evaluate it bit by bit, using C-M-f and C-x C-e (and later just M-x eval-buffer), which all worked fine. But along the way of the section-by-section, I got tired of typing all those, and so I recorded a keyboard macro... C-x ( C-M-f C-x C-e C-x ) and then C-x e... which gave me a message in the minibuffer (I think I'm using the right name), saying (Type e to repeat macro). Which meant I could no longer see the resultant value of the evaluation of each section of code... which, while not critical in this case, I was liking having. Which leads me to the actual question: Is there a way to disable that message, and/or to cause the minibuffer to show multiple lines at once? I know about the *Messages* buffer, and that could have helped, I'm just wondering if there's a way to either disable that message, or otherwise make it coexist with other messages. Any suggestions? Thanks! lindes * - the problem at hand, which is not really my question, is that (require 'ruby-mode/ruby-mode) fails, even though emacs is definitely and successfully (per system call tracing) opening and reading the ruby-mode.el file. I presume this is because the provide line says just 'ruby-mode. I've found a solution for this, but if anyone can point me to any "best practices", I'd appreciate it.

• Redirecting to a Facelet is not working when extending FaceletViewHandler

  - by Abel Morelos

  I'm overriding the handleRenderResponse method defined in com.sun.facelets.FaceletViewHandler: protected void handleRenderException(FacesContext context, Exception ex) I'm overriding this method so I can redirect the user to a custom error page (which contain the desired look and feel and other stuff). This is the way I'm trying to String errorPage = "/error.xhtml"; String contextPath = context.getExternalContext().getRequestContextPath(); String errorPagePath = contextPath+errorPage; context.getExternalContext().redirect(errorPagePath); The previous code is what I'm using to perform the redirect to this custom error page. Anyway, when I perform the redirect I'm prompted with a download dialog (this is with Internet Explorer, in Firefox the page does not display properly or as I would expect). I tried changing "/error.xhtml" to "/error.jsf" but in that case I get a 404 error. Somehow I think that the XHTML file is not being handled to the Facelets ViewHandler after the redirect, if I open the downloaded xhtml file I can see that the EL expressions were not resolved and the the ui tags were not handled. I don't have problems with other pages in my application, only when doing the redirect programatically. Important data from my web.xml: facelets.VIEW_MAPPINGS is set to *.xhtml javax.faces.DEFAULT_SUFFIX is set to .xhtml servlet-mapping for the "Faces Servlet" is ".jsf" and "/faces/"

  - by Ignacio

  For example, i want to zip a file stored in /Users/me/Desktop/image.jpg I maded this method: public static Boolean generateZipFile(ArrayList<String> sourcesFilenames, String destinationDir, String zipFilename){ // Create a buffer for reading the files byte[] buf = new byte[1024]; try { // VER SI HAY QUE CREAR EL ROOT PATH boolean result = (new File(destinationDir)).mkdirs(); String zipFullFilename = destinationDir + "/" + zipFilename ; System.out.println(result); // Create the ZIP file ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFullFilename)); // Compress the files for (String filename: sourcesFilenames) { FileInputStream in = new FileInputStream(filename); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(filename)); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file out.close(); return true; } catch (IOException e) { return false; } } But when i extract the file, the unzipped files have the full path. I don't want the full path of each file in the zip i only want the filename. How can i made this?

• Are there any configurable parameters to the gpsd?

  - by danatel

  I use the gpsd daemon with my application. Sometimes, the gpsd ceases to work with no apparent reason (clean sky). Even the gpsmon monitor shows no fix. Are there any parameters which must be set? Or is it a hardware problem? I am surprissed that many satellites are visible but the "Stat" bitmap does not contain the bit 7 - ephemeris data available. Should i somewhat pre-configure my position to allow for correct ephemeris data?

• How to parse text as JavaScript?

  - by Danjah

  This question of mine (currently unanswered), drove me toward finding a better solution to what I'm attempting. My requirements: chunks of code which can be arbitrarily added into a document, without an identifier: [div class="thing"] [elements... /] [/div] the objects are scanned for and found by an external script: var things = yd.getElementsBy(function(el){ return yd.hasClass('thing'); },null,document ); the objects must be individually configurable, what I have currently is identifier-based: [div class="thing" id="thing0"] [elements... /] [script type="text/javascript"] new Thing().init({ id:'thing0'; }); [/script] [/div] So I need to ditch the identifier (id="thing0") so there are no duplicates when more than one chunk of the same code is added to a page I still need to be able to config these objects individually, without an identifier SO! All of that said, I wondered about creating a dynamic global variable within the script block of each added chunk of code, within its script tag. As each 'thing' is found, I figure it would be legit to grab the innerHTML of the script tag and somehow convert that text into a useable JS object. Discuss. Ok, don't discuss if you like, but if you get the drift then feel free to correct my wayward thinking or provide a better solution - please! d

• Javascript: Check if checkboxes are selected on page load and add a class to parent html li

  Im looking a way to do it with prototype, this js, needs to loads with the page and interate over all the elements (inputs - checkboxes, in this case) with the given id and assign a class to its parent <li></li> The JS is: function changeSelectionStyle(id) { var inputId = id.substr(0,id.length-2); if(document.getElementById(inputId).checked){document.getElementById(id).className = 'yes';} alert(document.getElementById(inputId).checked); /* * if(document.getElementById(id).className != 'yes'){ * document.getElementById(id).className = 'yes'; * } else{document.getElementById(id).className = '';} */ } And the HTML (piece of it) that interacts with this JS is: <li id="selectedAuthorities-4_1li"> <input type="checkbox" id="selectedAuthorities-4_1" name="selectedAuthorities" value="ROLE_ADD_COMMENT_TO_CV" checked="checked" onclick="changeSelectionStyle(this.id + 'li'); checkFatherSelection(this.id);"> <a href="#" onclick="document.getElementById('selectedAuthorities-4_1').click(); return false;"> Agregar comentario <samp><b></b>Permite agregar comentario en el detalle</samp> </a> </li> After iteration, checking is the checkbox is checked, it has to add the class="yes" to the <li id="selectedAuthorities-4_1li">

• Wrong answer on c# application, finding the n prime of a list of prime numbers.

  - by user300484

  Hello, I am new to C# and I am practicing by trying to solve this easy C# problem. This application will receive an "n" number. After receiving this number, the program has to show the n prime of the list of primes. For example, if the user enters "3", the program is supposed to display "5", because 5 is the third prime starting at 2. I koow that something is wrong with my code but I dont know where is the problem and how I can fix it. Can you please tell me? Thank you :P using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Console.WriteLine("Determinar el n-esimo primo."); long n = Convert.ToInt64(Console.ReadLine()); // N lugar de primos long[] array = new long[n]; long c=0; while (c >= 2) { if(siprimo(c++) == true) for (long i = 0; i < n; i++) { array[i] = c; } } Console.WriteLine(array[n - 1]); Console.ReadLine(); } static private bool siprimo(long x) { bool sp = true; for (long k = 2; k <= x / 2; k++) if (x % k == 0) sp = false; return sp; } } }

• undefined returned for currentView object in Backbone.Marionette

  - by ontk

  I am testing how a layout can listen to its subviews's custom events. I created a jsFiddle here where I have a layout, 2 regions and I instantiated 2 ItemViews and showed them in the layout's regions. The fiddle is in CoffeeScript. <div id="region"></div> <script id="layout-tmpl" type="text/_"> <h3>Heading</h3> <div id="content"></div> <div id="content2"></div> </script> <script id="item-tmpl" type="text/_"> <form> <label>Firstname:</lable> <input type="text" name="firstname" value="<%= firstname %>" /> <input type="button" value="Save" id="save" /> </form> </script> And the CoffeeScript is: SimpleLayout = Backbone.Marionette.Layout.extend template: '#layout-tmpl' regions: main: '#content' other: '#content2' initialize: () -> console.log @ onShow: () -> _.each @.regionManagers, (region, name, something) => console.log region.currentView # @.bindTo region.currentView, "custom:event", @callback callback: () -> alert "HELL YEAH" SimpleItemView = Backbone.Marionette.ItemView.extend template: "#item-tmpl" events: 'click #save': 'save' save: (evt) -> evt.preventDefault() @.trigger "custom:event" region = new Backbone.Marionette.Region el: "#region" layout = new SimpleLayout() region.show layout layout.main.show new SimpleItemView model: (new Backbone.Model firstname: "Olivier") layout.other.show new SimpleItemView model: (new Backbone.Model firstname: "Travis") I want the layout to listen to the ItemViews's custom events. In the onShow, I am looping through the region managers and trying to access the currentView object but it returns undefined. If I attach the same event handlers outside of the SimpleLayout class and after I show the itemviews, then the layout handlers the custom events properly. Thanks for your help.

• How can I split my conkeror-rc config over multiple files?

  - by Ryan Thompson

  Short version: can you help me fill in this code? var conkeror_settings_dir = ".conkeror.mozdev.org/settings"; function load_all_js_files_in_dir (dir) { var full_path = get_home_directory().appendRelativePath(dir); // YOUR CODE HERE } load_all_js_files_in_dir(conkeror_settings_dir); Background I'm trying out Conkeror for web browsing. It's an emacs-like browser running on Mozilla's rendering engine, using javascript as configuration language (filling the role that elisp plays for emacs). In my emacs config, I have split my customizations into a series of files, where each file is a single unit of related options (for example, all my perl-related settings might be in perl-settings.el. All these settings files are loaded automatically by a function in my .emacs that simply loads every elisp file under my "settings" directory. I am looking to structure my Conkeror config in the same way, with my main conkeror-rc file basically being a stub that loads all the js files under a certain directory relative to my home directory. Unfortunately, I am much less literate in javascript than I am in elisp, so I don't even know how to "source" a file.

• How to filter what is shown in the for-each loop in XSL

  - by Denoteone

  I thought it would be as easy as tell the for-each to only select top_coach_sales_vw that has "Site" equal to "PB" but when I run the script it does not loop through any of the data in the XML. I am escaping the single quotes because it is part of a php echo. <xsl:for-each select="NewDataSet/top_coach_sales_vw[Site==\'PB\']"> <td><xsl:value-of select="name"/></td> <td><xsl:value-of select="Site"/></td> <td><xsl:value-of select="Status"/></td> </xsl:for-each> XML: <NewDataSet> <top_coach_sales_vw> <name>Mike</name> <Site>PB</Site> <State>Ready</State> </top_coach_sales_vw> <top_coach_sales_vw> <name>Bill</name> <Site>EL</Site> <State>Talking</State> </top_coach_sales_vw> <top_coach_sales_vw> <name>Ted</name> <Site>PB</Site> <State>Ready</State> </top_coach_sales_vw> </NewDataSet>

• jQuery AJAX PHP JSON problem

  Hi Gurus I'm facing the problem of receiving an empty array when I do an AJAX request in the following way: This is the code I'm executing in JavaScript: <script type="text/javascript" src="lib/jquery.js"></script> <script type="text/javascript" src="lib/jquery.json.js"></script> <script type="text/javascript"> $(document).ready(function(){ /* Preparar JSON para el request */ var mJSON = new Object; mJSON.id_consulta = new Array; for (var i=0; i<3; i++){ mJSON.id_consulta[i] = new Object; mJSON.id_consulta[i].id = i; } var sJSON = $.toJSON(mJSON); $.ajax({ type: "POST", url: "getUbicaciones.php", data: sJSON, dataType: "json", contentType: "application/json; charset=utf-8", success: function(respuesta){ alert(respuesta); }, error: function (request,error){ alert("Error: " + request.statusText + ".
