Me and ASMX web services do not get on. We argue. She brings up arguments we had in the past. It's a pain. Our relationship is on the rocks!
I have an ASMX web service, which I haven't serialised with the Newtonsoft library (as explained why here: http://encosia.com/2011/04/13/asp-net-web-services-mistake-manual-json-serialization/). It looks like this:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string[] GetCitiesWithState(string isoalpha2, string prefixText)
{
var dict = AtomicCore.CityObject.GetCitiesInCountryWithStateAutocomplete(isoalpha2, prefixText);
string[] cities = dict.Values.ToArray();
return cities;
}
Simple enough right? It return this when searching for new:
<?xml version="1.0" encoding="utf-8"?>
<ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/">
<string>New Orleans, Louisiana</string>
<string>New York, New York</string>
</ArrayOfString>
I was expecting JSON, but after a bit of reading, it seems I shouldn't try and serialise the output - it should just happen right? Anyway, so I have the following JQuery on the frontend:
$('#<%=txtCity.ClientID%>').autocomplete('<%=ResolveUrl("~/AtomicService/Assets.asmx/GetCitiesWithState")%>', {
dataType: 'json',
httpMethod: 'POST',
contentType: 'application/json; charset=utf-8',
parse: function (data) {
var rows = new Array();
for (var i = 0; i < data.d.length; i++) {
rows[i] = { data: data.d[i], value: data.d[i].Value, result: data.d[i].Value };
}
return rows;
},
formatItem: function (row, i, n) {
return row.Value;
},
extraParams: {
minChars: 2,
isoalpha2: '<%=Session["BusinessCountry"].ToString()%>',
maxRows: 20,
prefixText: function () {
return $('#<%=txtCity.ClientID%>').val()
}
},
max: 20
}).result(function (event, data, formatted) {
if (data) {
alert(data['Key']);
}
});
I can see the calls using Chrome:
And yet stuff all happens! There is no Jquery errors, no fireworks, no anything. She is ignoring me.
At first I was blaming the webservice, but I think this may have more to do with how I'm parsing and formatting the data in jquery.
So, my question is, what am I doing wrong and how can I make the autocomplete work correctly?
Help appreciated :)
EDIT: It may not be helpful, but this is what I see in Fiddler:
