JQuery :: Compute JSON In JTemplate In Webservice Manually?
Mar 31, 2011
I have a webservice which retrieves data from another external service. The data is already in JSON Format. So I retrieve it and set it to the return value (type: string) of my webservice. But according to firebug the webservice then encapsulates the provided JSON-Data with a backslash, e.g. it returns:
[Code]....
instead of
[Code]....
But the JSON provided by the external service is correct. So how could I provide the correct string to jTemplate from my Webservice?
i want to get data from my database and dispaly it in my web page using json with webservicei'm going to post my code i create a webservice and add method which return string to get all data so my code like this
I have been trying for two months to get this code working, and I am close, but still confused. I want the JQuery UI Autocomplete function to call an web service which returns JSON data and display that data for selection, and on selection put the selected value into a hidden field.
There are several issues:
1) The autocomplete function is not firing 2) The source: "/AutoSuggest.asmx/DOTFind?" line throws an invalid object exception 3) The service requires two parameters: (string prefixText, int count) - count tells it how many records to return. 4) I am not at all certain that this code will accept JSON data that comes back from the service
I have an ASP.NET webservice method that returns a generics list (List'<'Construct>) serialized as JSON, using code such as this:
[WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] public class TestService : System.Web.Services.WebService { [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public string GetOccupationListJSON(int SOCLevel) { Construct NewConstructList = new ConstructList(); DataContractJsonSerializer serializer = new DataContractJsonSerializer(ConstructList.GetType()); MemoryStream ms = new MemoryStream();
[Code]....
I assumed (from looking elsewhere) that accessing the JSON data through the index would provide me with access to the underlying object at that index, so that I can then work with it to access its properties. However, when i=0 and I do var Construct = data[i]; I get the character at the i position of the data array ([), and in the next iteration I get the second character ({). So clearly I am accessing the elements of a string array rather than the JSON data object.How do I make sure that the data returned by the webservice gets into proper JSON format, so that I can iterate through the object elements within it?
i am using combination of jquery and JSON based webservice in most of projets. Lately i am facing this problem. if the data returned from webservice is huge ajax call from jquery fails. yup i know i can implement paging etc etc but is there a way i can increase the limit to get more data from webservice with jquery ajax call?
I have a webservice which returns 1 single table with 1 single row. That works fine. Now I call it with jQuery, that also works fine. But when assigning it to a jTemplate I always get the error: "error". : I haven't found any example for datasets. tables, or rows, just for lists. But is it also possible to use jTemplate with a single row returned from Webservice?
I have DataReader that holds the results from a stored procedure caal. The results consist of two fields ...
UserID UserName
Normally I bind these results to an ASP.NET dropdownlist control ...
ddlUserList.DataSource = rdr // rdr is the DataReader ddlUserList.DataTextField = "UserName" ddlUserList.DataValueField = "UserID" ddlUserList.DataBind()
However I am now trying to accomplish the same thing using jQuery AJAX. What I am stuck on is how to manually convert the dataset held in the DataReader to JSON. How are multiples values separated? Does this look correct?
I realize there are libraries out there such as JSON.NET to handle the serialization but I am in the learning stage now and want to make sure I understand everything from the bottom up.
Does anyone know of free webservice that returns a list in the form of JSON? I have searched many webservice sites but they all return xml. Geonames.org is not required.
The main issue is that I cannot run a webservice that accepts requests in JSON format. I keep getting a 500 Server error stating that the "request format is invalid." My ASP.NET AJAX extensions are installed. My server is running Plesk Control Panel 8.6 which is undoubtedly causing these problems.
The default handler for this specified extension is shown in the web.config like so:
For my applications webservice to handle JSON it needs to have this reference:
Plesk is not allowing the request to be handled properly. I need to know the correct http directive(s) to put into the web.config to properly handle JSON webservices.
I have trouble with JSON response compression. I look to response headers after uploading website to production server (Windows 2008, IIS 7) and found uncompressed response. Turning on "Enabled static compression" and ""Enable dynamic compression" in IIS control panel does not effect. ASPX pages was responsed gzipped, but webservice response uncompressed.
I looked to google, but no answer found about this trouble. Also, I try this [URL] way (and adding to web.config this module) - but this source is excellent working at development machine with ASP.NET development server (and have seven times response size reduced) and totally ignored at IIS7.
How I can apply gzip compression to json responses from my webservice?
I need to make a call to a json webservice from C# Asp.net. The service returns a json object and the json data that the webservice wants look like this:
"data" : "my data"
This is what I've come up with but I can't understand how I add the data to my request and send it and then parse the json data that I get back.
string data = "test"; Uri address = new Uri("http://localhost/Service.svc/json"); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address); request.Method = "POST"; request.ContentType = "application/json; charset=utf-8"; string postData = "{"data":"" + data + ""}";
How can I add my json data to my request and then parse the response?
I have two parameters (categoryName and categoryDescription) that I need to pass to the web service using JSON. I found the syntax to pass categoryName but have not been able to get the correct syntax to pass both parameters. Here is the code.
I have successfully returned data from a ASP.Net webservice in JSON format (using a service method that required no parameters) but have struggled with making a webservice call that requires a parameter.
Webservice:
<WebMethod()> _ <ScriptMethod(ResponseFormat:=ResponseFormat.Json, UseHttpGet:=True)> _ Public Function TestWebService(ByVal Description As String) As Stock Dim res As New Stock(Guid.NewGuid, Description) Return res
I have a website where I am using the JSON webservice. I have uploaded my website on the server.
Problem:
When I try to access the webservice it gives me the error as shown in below screenshot. In the below screenshot MyServices is my webservice. MyServices.asmx is the name of the file that I am trying to access.
Troubleshooting that already has been done:
I tried cleaning the bin folder and rebuilding again. But it didnt work.
I have a simple webservice that I would like to upload a file to. The problem is that I need the response in json.
Form my experience in order to get a response in Json my request has to have a content-type of 'application/json'. But ofcourse this cannot be the case with a file upload since the content type will have to be 'multipart/form-data'.
In my Json i want to return a value showing whether successful and a filename.
Is it possible to update an UpdatePanel manually using JavaScript or jQuery?
What I have is a TextBox at the top of my page. When a user leaves that TextBox I want to run some server code (it will add a record to my database) then at the bottom of the page I have an UpdatePanel which will get refreshed. The UpdatePanel has a GridView which will have an entry for the record added)
