using jquery to read an Asp.net arraylist

Question

I have a web method in ASP.net which it's output is an ArrayList and read cities from databse. this web method is called using jquery.

$.ajax(
    { url: "../AjaxServices/StateCity.asmx/showcity",
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        type: "POST",
        data: '{s: ' + $('#<%=DpState.ClientID%>').val() + '}',
        success: function(data) {

}

I wanna know how to loop through data, because the data is object. I knew about

jQuery.each( collection, callback(indexInArray, valueOfElement) )

but doesn't work

Look at the response and the data parameter in Firebug.

When you call an ASP.Net WebMethod using AJAX, it returns an object with a d property containing your data.

If your WebMethod returns a collection, you can write

$.each(data.d, function(index, obj) { ... });

Slaks answer is great a ndI found a solution base on SLaks answer, so I'll share it here: just take care about Value and Text they're case sensitive.

success: function(data) { 
                $.each(data.d, function() {   
                  alert(this['Value'] + ':' + this['Text']);                 })             }
