Answer a quetsion -- 2

I make an ajax call to populate a select This works: I want to then populate the rest of the form with data that was returned from the ajax call I tried this but the data object is undefined. How do I pass the data object into the change event $.ajax({ url: "/_handlers/[login to view URL]", data: {userRole_ID: 1300}, dataType: 'json', type: 'POST', contentType: 'application/x-www-form-urlencoded', success: function (data) { $('#ddl_users').html('<option value="0" title="Add a new client user"> Add New</option> '); $.each(data, function (index, item) { $('#ddl_users').append('<option value="' + [login to view URL] + '" title="' + [login to view URL] + '">' + [login to view URL] + '</option>'); }) $('#ddl_users').on('change',function (data) { //alert('hi'); alert($(this).val()); $.each(data, function (index, item) { alert([login to view URL]); //if ($(this).val() == [login to view URL]) { // alert('match:' + $(this).val() + ': ' + [login to view URL]); //} }); }); }, error: function (data, status, jqXHR) { alert('There was an error loading User Data.'); } });
