Question

I want to call a web service method in javascript. (asp.net 3.5)

I have traced the result with firebug .
here is the result:

{"d":"[{\"TI\":\"www\"},{\"TI\":\"www1\"}]"}

I think the correct result should like this

{"d":[{\"TI\":\"www\"},{\"TI\":\"www1\"}]}

what is the quotation before and after the Bracket ?

// edited :
in webserivce:

public class Test
    {
        public Test(string t){T1 = t;}
        public string T1 { set; get; }
    }

    [WebMethod]
    [ScriptMethod(ResponseFormat = ResponseFormat.Json, UseHttpGet = true, XmlSerializeString = false)]
    public string Load(string e)
    {
        List<Test> post = new List<Test> { new Test("www"), new Test("www1") };
        return JsonConvert.SerializeObject(post);
    }

and in js file :

 var store = new Ext.data.JsonStore({
        proxy: new Ext.data.HttpProxy({
            url: '/core/webservice/service.asmx/Load',
            method: 'GET',
            headers: { 'Content-type': 'application/json' }
        }),
        root: 'd',
        id: 'Id',
        fields: ['TI']
    });
    store.load({ params: { e: ''} });
    return; 

thank you .

You shouldn’t need to serialize manually in the web service; consider using something like this instead:

public List<Test> Load(string e)
{
    List<Test> post = new List<Test> { new Test("www"), new Test("www1") };
    return post;
}

Since you’re using string as your return object, it will convert it as that for you when serializing it (once again).
