通过JSOn结果进行迭代

Question

I have a WebMethod being called from ajax, trying to iterate through the returned data. The data being returned is "{ BusinessTypeID = 2 }". I'm trying to figure out how to just get the value 2?

        //Function called from ajax
[System.Web.Services.WebMethod]
public static string[] GetTerminalBusinessTypes(string terminalID)
{
    DataClassesDataContext db = new DataClassesDataContext();
    List<string> results = new List<string>();

    try
    {

        var terminalBusinessTypes = (from bt in db.BusinessTypes
                                    join obt in db.OxygenateBlenderBusinessTypes on bt.BusinessTypeID equals obt.BusinessTypeID
                                    where obt.OxygenateBlenderID == Convert.ToInt32(terminalID)
                                    select new
                                    {
                                        bt.BusinessTypeID
                                    }).ToList();


        for (int i = 0; i < terminalBusinessTypes.Count(); i++)
        {
            results.Add(terminalBusinessTypes[i].ToString());
        }

    }
    catch (Exception ex)
    {

    }

    return results.ToArray();
}

The ajax function:

            function PopulateTerminalBusinessTypes(terminalID) {

        $.ajax({
            type: "POST",
            url: "OxygenateBlenderCertificationApplication.aspx/GetTerminalBusinessTypes",
            data: "{'terminalID':" + terminalID + "}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data) {

                var targetValue = data.d;

                var items = $('#cblTerminalBusinessType input:checkbox');



                                    $.each(targetValue, function (key, targetValue) {
                                        alert(data[index].BusinessTypeID);
                                    });
                    }
        })//end ajax

    }

To be honest I cannot see where your "index" is defined.

Shouldn't the alert line read

$each(targetVale, function(key, item) {
   // on second look, this wont work as you are converting toString()
   alert(targetValue[key].BusinessTypeId)
   // this should
   alert(item)
});

You could also throw a debugger; line above the alert and see the values being traversed.
