Trying to get a test bed working for jQuery UI V10 Autocomplete. I have the demo programs working, but when I adapt the code to an example using C# and an ASP.NET webservice, I am getting a status 200 parseerror. The jSon data is coming back wrapped in double quotes. When I put the response in jsonLint, it validates when I remove the outer quotes. It also has the "d." prefix that I expect from an ASP webservice.
How do I get the response to return valid JSON?
jQuery code:
$(settings.selector).autocomplete({
source: function (request, response) {
var data = JSON.stringify({
prefixText: request.term,
count: settings.count
});
ajaxCall(settings.url, data, {
onSuccess: function (data) {
var matches = [];
$.each(data, function (item) {
matches.push({
label: data[item].label,
value: data[item].value,
id: data[item].id
});
});
response(matches);
}
});
},
minLength: settings.minLength,
change: function (event, ui) {
if (ui && ui !== null && ui.item && ui.item !== null) {
currentValue = ui.item.label;
if (settings.onChange && settings.onChange !== null) {
settings.onChange(ui.item, settings.selector, oldValue);
}
} else {
$(settings.selector).val(oldValue);
}
},
select: function (event, ui) {
currentValue = ui.item.label;
if (settings.onSelect && settings.onSelect !== null) {
settings.onSelect(ui.item, settings.selector, oldValue);
}
},
open: function () {
$(this).removeClass("ui-corner-all").addClass("ui-corner-top");
},
close: function () {
$(this).removeClass("ui-corner-top").addClass("ui-corner-all");
}
});
WebService Code:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]
public class TestAutocomplete : System.Web.Services.WebService
{
[WebMethod(BufferResponse = true, Description = "Lookup City")]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string CityList(string prefixText, int count)
{
List<AutoSuggestReturn> matches = AssessorBusinessLayer.City.List(prefixText, count);
Messages.ConsoleLog(string.Format("Prefix: {0} return {1} matches", prefixText, matches.Count));
string ret = AutoSuggestReturn.ConvertToJson(matches);
return ret;
}
}
