Javascript - Accessing Elements Of JSON Object Without Knowing The Key Names
Feb 25, 2011Here's my json:
{"d":{"key1":"value1",
"key2":"value2"}}
Is there any way of accessing the keys and values (in javascript) in this array without knowing what the keys are?
The reason my json is structured like this is that the webmethod that I'm calling via jquery is returning a dictionary. If it's impossible to work with the above, what do I need to change about the way I'm returning the data?
Here's an outline of my webmethod:
<WebMethod()> _
Public Function Foo(ByVal Input As String) As Dictionary(Of String, String)
Dim Results As New Dictionary(Of String, String)

Convert JSON String To JSON Object?

Javascript - Pass JSON File From ASP.NET To JQuery?
Feb 27, 2012my problem is that my company does not want to serve up the .json MIME type, so I have to use ASP.NET to fetch the JSON file from the file server. Currently I have jQuery that does a getJSON and traverses the JSON object to build certain elements of the page. Is there a way I can use ASP.NET (VB) to give the object to my jQuery script after I fetch it?
View 1 RepliesJavascript - JSON Array Type Resolution In ASP.Net Webservices?
Jan 6, 2011I have worked out how to pass my custom objects into ASP.Net json webservices. Works a charm. Problem I am having is passing in straight arrays of my custom objects or alternatively passing in arrays that are parameters of my custom objects. So for example...
Public Class WebService1
Inherits System.Web.Services.WebService
<WebMethod()> _
[code]....
Fails with error: The value "System.Collections.Generic.Dictionary`2[System.String,System.Object]" is not of type "WebApplication1.WebService1+Person" and cannot be used in this generic collection. Parameter name: value
So how do I explain to ASP.net that it is infact an array of Person? note: That changing the function to as List(of Person) or ArrayList does work but given that I implement my own custom collections this is not optimal for me.
UPDATE: Ok so what I have worked out so far is that this problem is definitely associated with how the JavascriptSerializer uses the SimpleTypeResolver to resolve types. Basically if I do something like this
Public Function AddPersonList(ByVal PersonList As String) As PersonList
I can recreate the error using the following code.
Dim PersonList As PersonList = jsonSerializer.Deserialize(Of PersonList)(PList)
However when I provide my own custom type resolver along the lines of
Dim jsonSerializer As New JavaScriptSerializer(New MyCustomTypeResolver)
I can successfully create an instance of my custom list.Now I have worked out how to provide my own custom convertor in the web.config file. Along the lines of this....
<system.web.extensions>
<scripting>
<webServices>
[code]....
PSS: I have tried to use the assembly fully qualified name as specified in the docs for the SimpleTypeResolver (SimpleTypeResolver MSDN) but this throws a "Operation is not valid due to the current state of the object." exception - which is an error caused when the TypeResolver cannot resolve the name?
My problem was never passing in a List(of Object) into my webservice (I simply posed the question as such to simplify it for stackoverflow). In such a case I would be willing to completely accept using a Generic List(of) but my problem was actually that one of my custom objects implemented a property with a strong typed List(of) so for example:
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS EmailAddressList}
which now needs to be changed to
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS List(Of EmailAddress)}
This is admittedly not the end of the world and is probably better in the webservice context (as you have suggested) but definitely a detriment when it comes to internal application usage of my Collection properties. What this means is that once I have this property I either need to cast it to my CustomCollectionList every time I want to use some advanced feature or I need to implement another property which exposes the CustomCollectionList.
Passing A JSON Object As A Dictionary(Of String, Object) To WCF Web Service?
