  • Access multiple objects/arrays in JSON in jQuery $.each

    - by user2880254
    I am trying to build a simple page to view messages saved in a mysql db via JSON and jQuery. My JSON IS {"unread_msgs":[{"id":"6","title":"33333","user1":"19","timestamp":"1383747146","client_id":"Generic"},{"id":"5","title":"42142","user1":"19","timestamp":"1383740864","client_id":"Generic"}],"read_msgs":[{"id":"4","title":"test to addnrow","user1":"19","timestamp":"1383676647","client_id":"Generic"},{"id":"2","title":"kll","user1":"19","timestamp":"1383675548","client_id":"Generic"},{"id":"1","title":"jkjljklj","user1":"19","timestamp":"1382539982","client_id":"Generic"}],"urm_t":2,"rm_t":3} My JS <script type="text/javascript"> function GetClientMsgs () { $.post("assets/server/client_msgs.php",{ client_id:local_client_id } ,function(data) { var MsgData = $.parseJSON(data); console.log("Msg json data parsed"); $.each(MsgData, function(key, value) { console.log(value); $('#unread_row').append('<td><a href="#read_pm" onClick="ReadMsg('+value.unread_msgs.id+'); return false;">'+value.unread_msgs.title+'</a></td><td><a href="#profile">'+value.unread_msgs.studioname+'</a></td><td>'+value.unread_msgs.timestamp+'</td><td><a href="#delete_msg" onClick="DeleteMsg('value.unread_msgs.id+'); return false;">X</a></td>'); $('#read_row').append('<td><a href="#read_pm" onClick="ReadMsg('+value.read_msgs.id+'); return false;">'+value.read_msgs.title+'</a></td><td><a href="#profile">'+value.read_msgs.studioname+'</a></td><td>'+value.read_msgs.timestamp+'</td><td><a href="#delete_msg" onClick="DeleteMsg('+value.read_msgs.id+'); return false;">X</a></td>'); }); }); } </script> PHP $msgs = array('unread_msgs' => $dn1s, 'read_msgs' => $dn2s, 'urm_t' => $unread_msgs, 'rm_t' => $read_msgs); $json = json_encode($msgs); I am trying to post values returned such as unread_msgs.title or .id and am not able to access any of the objects. I have searched on here and could not find something specific to my structure. Thanks alot.

  • Using json_encode on objects in PHP

    - by Alan
    Hi, I'm trying to output lists of objects as json and would like to know if there's a way to make objects usable to json_encode? The code I've got looks something like $related = $user->getRelatedUsers(); echo json_encode($related); Right now, I'm just iterating through the array of users and individually exporting them into arrays for json_encode to turn into usable json for me. I've already tried making the objects iterable, but json_encode just seems to skip them anyway.

  • Get nested data from local JSON file

    - by Lbase
    Now that I have the NSDictionary object JSONDictionary, how do I get the nested data inside of it? NSString *JSONFilePath = [[NSBundle mainBundle] pathForResource:@"sAPI" ofType:@"json"]; NSData *JSONData = [NSData dataWithContentsOfFile:JSONFilePath]; NSDictionary *JSONDictionary = [NSJSONSerialization JSONObjectWithData:JSONData options:kNilOptions error:nil]; NSLog(@"Dictionary: %@", JSONDictionary); sAPI.json snippet: { "ss": [{ "name": "bl", }, "ls": [{ "name": "ML", "abbreviation": "ml", "id": 10,

  • How to select data in JSON based on other JSON data? Javascript

    - by user1699030
    Is it possible to select certain data in a JSON Object using other data in the same JSON Object. Similar to MySQL. For example: myObj = {"elements" : [ { "name" : "Hydrogen", "symbol" : "H" }, { "name" : "Silver", "symbol" : "Ag" }]}; I want to select "Hydrogen" where the symbol is "H". Instead of having to put in something like this: document.getElementByID("TEST").innerHTML = myObj.elements[0].name; Thank you in advance.

    - by Bi

I however need to read it in my C# application. Whats the best way to do so for JSON? The above keys are not associated with a class.

  • JSON.parse vs. eval()

    - by Kevin Major
    My Spider Sense warns me that using eval() to parse incoming JSON is a bad idea. I'm just wondering if JSON.parse() - which I assume is a part of JavaScript and not a browser-specific function - is more secure.

  • MVC 2: Html.TextBoxFor, etc. in VB.NET 2010

    - by Brian
    Hello, I have this sample ASP.NET MVC 2.0 view in C#, bound to a strongly typed model that has a first name, last name, and email: <div> First: <%= Html.TextBoxFor(i => i.FirstName) %> <%= Html.ValidationMessageFor(i => i.FirstName, "*") %> </div> <div> Last: <%= Html.TextBoxFor(i => i.LastName) %> <%= Html.ValidationMessageFor(i => i.LastName, "*")%> </div> <div> Email: <%= Html.TextBoxFor(i => i.Email) %> <%= Html.ValidationMessageFor(i => i.Email, "*")%> </div> I converted it to VB.NET, seeing the appropriate constructs in VB.NET 10, as: <div> First: <%= Html.TextBoxFor(Function(i) i.FirstName) %> <%= Html.ValidationMessageFor(Function(i) i.FirstName, "*") %> </div> <div> Last: <%= Html.TextBoxFor(Function(i) i.LastName)%> <%= Html.ValidationMessageFor(Function(i) i.LastName, "*")%> </div> <div> Email: <%= Html.TextBoxFor(Function(i) i.Email)%> <%= Html.ValidationMessageFor(Function(i) i.Email, "*")%> </div> No luck. Is this right, and if not, what syntax do I need to use? Again, I'm using ASP.NET MVC 2.0, this is a view bound to a strongly typed model... does MVC 2 still not support the new language constructs in .NET 2010? Thanks.

  • .NET Framework 4 Client Profile vs .NET Framework 3.5 Client Profile

    - by Janusz
    Currently I am targeting .NET Framework 3.5 Client profile. Under certain conditions (when .NET 1.x or 2.x is installed) the client profile is not installed and instead full version of .NET Framework 3.5. is installed. This limitation has been removed from .NET 4.0 profile - therefore its a nice improvement that significantly reduces download size on certain PCs. However, if I target application to .NET 4.0 then all the clients will have to download new framework. I think ideal scenario would be to target .NET 3.5 profile but point installer to .NET 4.0 client profile. This way PCs with 3.5 installed (65% from our tests at the moment) would be fine and the rest would install .NET 4.0. Is my thinking correct or its not feasible? Will .NET 3.5 profile application run with only .NET 4.0 profile installed? Thank you

  • How do I install ASP.NET MVC 2 Futures?

    - by Zack Peterson
    I want to use the DataAnnotations.DisplayAttribute.Order property to arrange my fields when using the DisplayForModel and EditorForModel methods. Related question: Does the DataAnnotations.DisplayAttribute.Order property not work with ASP.NET MVC 2? I think that I need to use the ASP.NET MVC 2 Futures. But I can't get it to work. How do I install ASP.NET MVC 2 Futures? Why are my fields still out of order?

  • You may get "A potentially dangerous Request.QueryString value was detected from the client" after u

    - by anas
    I was upgradting one of the DNN portals to ASP.NET 4.After Upgrading completed and when i configured it to run under asp.net 4 in iis, I started to get that exception on every postback. The mentioned exception is happening because in ASP.NET 4, the request validation is now being called for every asp.net resource like web services and other httphandlers.As a result, you may get that exception even if you turned off the RequestValidation via: <pages validateRequest="false" .... section.

  • Install Quartz.Net as a windows service and Test installation

    - by Tarun Arora
    In this blog post I’ll be covering, 01: Where to download Quartz.net from 02: How to install Quartz.net as a Windows service 03: Test the Quartz.net Installation If you are new to Quartz.net I would recommend reading the blog post on a brief introduction to Quartz.net. 01 – Where to download Quartz.net? http://sourceforge.net/projects/quartznet/files/quartznet/       Currently version  Quartz.Net 2.0.1 is the recommended download version. 02 – How to install Quartz.net as a Windows service         Go to the download location and unzip the Quartz.net package Navigate to the folder Quartz.Net \ Server \ bin – This is where you will find different .net version installers of the quartz.net packages. For example in the screen shot above, you can see the Quartz.net .net 3.5 and .net 4 packages. Open up the Quartz.net .net 4.0 folder, this folder contains the files you need to install Quartz.net as a windows service Copy the contents of the folder Downloads\Quartz.NET-2.0.1\server\bin\4.0 to the folder %program files%\Quartz.net   5. Open up a new CMD as an administrator and run the below command to install Quartz.net as a windows service /> Quartz.Server.exe install 6. How do I know that Quartz.Net service has installed as a Windows service? Go to run prompt and type ‘services.msc’ you should now see all the windows services installed on your machine. Navigate down to look for Quartz.Net. The service installs itself as an automatic startup Type and log on as ‘Local System’. You can easily change this to your prefer account that you would like to run the service as. If you wanted to name the Quartz service something else then that’s also possible… Can I change the default display name of the quartz.net windows service? Yes, you can! Navigate to C:\Program Files (x86)\Quartz.Net\ and open up the config file ‘quartz.config’ - You can change the instance name - You can change the default thread count of 10 - The port that the service listens to (by default this is port 555) A blog post on more configuration details can be found here. 03 – Test Quartz.Net windows service installation So, I have installed Quartz.Net as a windows service, how do I test whether my installation has been successful. Open up cmd as an administrator and run the below command, C:\Program Files (x86)\Quartz.Net> Quartz.Server.exe –i Since by default the Quartz.net windows service writes INFO level diagnostics (this can be changed from Quartz.Server.exe.config) you should see the service information show up on the console. For instance in the example above I can see that the service is running in a NON CLUSTERED mode, its currently not started and is currently in standby mode with 0 number of jobs executed so far… This was second in the series of posts on enterprise scheduling using Quartz.net, in the next post I’ll be covering how to run your first scheduled task using Quartz.net windows service.

  • .net compact framework backward compatibility 3.5 and 2.0

    - by mack369
    Do I need to install .net 2.0 on the device, where .net 3.5 is installed? So far my application works on .net 2.0 (which potentially should be faster) but the long term plan is to port it to .net 3.5. I need to order devices and the OEM needs to know which version of .net should be add to Windows CE image (version 5.0). Shall I ask him to add both .net 2.0 and .net 3.5 ?

    I have seen there are lots of myth’s about asp.net web services in fresher level asp.net developers. So I decided to write a blog post about asp.net web services interview questions. Because I think this is the best way to reach fresher asp.net developers. Followings are few questions about asp.net web services. 1) What is asp.net web services? Ans: Web services are used to support http requests that formatted using xml,http and SOAP syntax. They interact with through standards xml messages through Soap. They are used to support interoperability. It has .asmx extension and .NET framework contains http handlers for web services to support http requested directly. 2) What kind of data can be returned web services web methods? Ans: It supports all the primitive data types and custom data types that can be encoded and serialized by xml. You can find more information about that from the following link. http://msdn.microsoft.com/en-us/library/bb552900.aspx 3) Is web services are only written in asp.net? Ans: No, It can be written by Java and PHP languages also. 4) Explain web method attributes in web services Ans: Web method attributes are added to a public class method to indicate that this method is exposed as a part of XML web services. You can have multiple web methods in a class. But it should be having public attributes as it will be exposed as xml web service part. You can find more information about web method attributes from following link. http://msdn.microsoft.com/en-us/library/byxd99hx(v=vs.71).aspx 5) What is SOA? Ans: SOA stands for “Services Oriented Architecture”. It is kind of service oriented architecture used to support different kind of computing platforms and applications. Web services in asp.net are one of the technologies that supports that kind of architecture.  You can call asp.net web services from any computing platforms and applications. 6) What is SOAP,WDSL and UDDI? Ans: SOAP stands “Simple Object Access protocol”. Web services will be interact with SOAP messages written in XML. SOAP is sometimes referred as “data wrapper” or “data envelope”.Its contains different xml tag that creates a whole SOAP message.  WSDL stand for “Web services Description Language”.  It is an xml document which is written according to standard specified by W3c. It is a kind of manual or document that describes how we can use and consume web service. Web services development software processes the WSDL document and generates SOAP messages that are needed for specific web service. UDDI stand for “Universal Discovery, Description and Integration”. Its is used for web services registries. You can find addresses of web services from UDDI.

  • ASP.NET Server-side comments

    - by nmarun
    I believe a good number of you know about Server-side commenting. This blog is just like a revival to refresh your memories. When you write comments in your .aspx/.ascx files, people usually write them as: 1: <!-- This is a comment. --> To show that it actually makes a difference for using the server-side commenting technique, I’ve started a web application project and my default.aspx page looks like this: 1: <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ServerSideComment._Default" %> 2: <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> 3: </asp:Content> 4: <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> 5: <h2> 6: <!-- This is a comment --> 7: Welcome to ASP.NET! 8: </h2> 9: <p> 10: To learn more about ASP.NET visit <a href="http://www.asp.net" title="ASP.NET Website">www.asp.net</a>. 11: </p> 12: <p> 13: You can also find <a href="http://go.microsoft.com/fwlink/?LinkID=152368&amp;clcid=0x409" 14: title="MSDN ASP.NET Docs">documentation on ASP.NET at MSDN</a>. 15: </p> 16: </asp:Content> See the comment in line 6 and when I run the app, I can do a view source on the browser which shows up as: 1: <h2> 2: <!-- This is a comment --> 3: Welcome to ASP.NET! 4: </h2> Using Fiddler shows the page size as: Let’s change the comment style and use server-side commenting technique. 1: <h2> 2: <%-- This is a comment --%> 3: Welcome to ASP.NET! 4: </h2> Upon rendering, the view source looks like: 1: <h2> 2: 3: Welcome to ASP.NET! 4: </h2> Fiddler now shows the page size as: The difference is that client-side comments are ignored by the browser, but they are still sent down the pipe. With server-side comments, the compiler ignores everything inside this block. Visual Studio’s Text Editor toolbar also puts comments as server-side ones. If you want to give it a shot, go to your design page and press Ctrl+K, Ctrl+C on some selected text and you’ll see it commented in the server-side commenting style.

  • Dynamic data validation in ASP.NET MVC

    - by user252160
    I've recently read about the model validation capabilities of ASP.NET MVC which are all very cool until a certain point. What happens if the application doesn't know the data that it works with because it is all stored in DB and built together at runtime. Just like in Drupal, I'd like to be able to define custom types at runtime, and assign runtime validation rules as well. Obviously, the idea of assigning attributes to well established models is now gone. What else could be done ? I am thinking in terms of rules being stored as JSON objects in the DB fields or something like that.

  • How do I put my return data from an asmx into JSON?

    - by jphenow
    I want to return an array of javascript objects from my asp.net asmx file. ie. variable = [ { *value1*: 'value1', *value2*: 'value2', ..., }, { . . } ]; I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable. Thanks in advance for assistance. EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.

  • Connecting to TFS via ASP.NET, jQuery and Phonegap

    - by Tony D.
    I want to develop a mobile application that would allow the user the ability to run a suite of automated test cases housed in TFS. This is something I thought of this morning so it's all still very preliminary. But I'm curious as to what would be the best route for something like this? Or if it's even possible? Because the mobile devices from the users will vary from iphones to droids, I would probably want to incorporate something like Phonegap for it's cross platform capabilities. My initial thought was to develop in ASP.net/C# (which would be stored on a remote server), and have jQuery make calls to that server. Not sure if that would be the most appropriate way of handling this. I'm not too familiar with JSON but I have seen it as a suggestion on various sites to handle the returned data. Any thoughts or suggestions are appreciated. Thanks.

  • JQuery Json error: Object doesn't support this property or method

    - by Abu Hamzah
    ERROR: Microsoft JScript runtime error: Object doesn't support this property or method i am using WCF service to pull the data and its very simple for the purpose of test and it does returning me the data from wcf service but it fails on json2.js on line number 314-316 // We split the first stage into 4 regexp operations in order to work around // crippling inefficiencies in IE's and Safari's regexp engines. First we // replace all backslash pairs with '@' (a non-JSON character). Second, we // replace all simple value tokens with ']' characters. Third, we delete all // open brackets that follow a colon or comma or that begin the text. Finally, // we look to see that the remaining characters are only whitespace or ']' or // ',' or ':' or '{' or '}'. If that is so, then the text is safe for eval. if (/^[\],:{}\s]*$/.test(text.replace(/\\["\\\/bfnrtu]/g, '@'). replace(/"[^"\\\n\r]*"|true|false|null|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?/g, ']'). replace(/(?:^|:|,)(?:\s*\[)+/g, ''))) { here is what i am doing function serviceProxy(wjOrderServiceURL) { var _I = this; this.ServiceURL = wjOrderServiceURL; // *** Call a wrapped object this.invoke = function (options) { // Default settings var settings = { serviceMethod: '', data: null, callback: null, error: null, type: "POST", processData: false, contentType: "application/json", dataType: "text", bare: false }; if (options) { $.extend(settings, options); } function GetFederalHolidays() { $("#dContacts1").empty().html('Searching for Active Contacts...'); ContactServiceProxy.invoke({ serviceMethod: "Holidays", callback: function (response) { // ProcessActiveContacts1(response); debugger }, error: function (xhr, errorMsg, thrown) { postErrorAndUnBlockUI(xhr, errorMsg, thrown); } }); } any help what iam doing wrong? i try to change from dataType: text to json but i get the same error above.
