getJSON $。每个都不显示值

Question

I have the following getJSON that calls an MVC controller which returns inforamtion back:

    $.getJSON('@Url.Action("List", "Spkr")',
              { id: spkrid},
            function (data) {

                     $.each(data.spk, function () {
                               alert(spk.ID);
                      });
     });

The JSON object looks like the following: {"spk":[{"ID":31,"Title":"SprkTitle","Status":"Onlne"}]}

The .each is not showing the anything in the alert. Not sure if I have it configured wrong.

Answer 1

I see no definition/declaration of spk
the $.each method can take a function like function(index, value) as the second parameter where index is the index of the current item and value is its value i.e. data.spk[index == value
So this should work

$.each(data.spk, function (index, spk) {
    alert(spk.ID);
});
