試圖獲得測試平臺爲jQuery UI V10自動完成工作。我有演示程序工作，但是當我使用C＃和ASP.NET webservice將代碼調整爲示例時，我得到的狀態爲200 parseerror。 jSon數據重新包裝在雙引號中。當我將響應放入jsonLint中時，它將驗證我何時刪除外部引號。它也有「d」。前綴，我期望從ASP Web服務。jQuery自動完成小部件在調用C＃webservice時會得到ParseError
如何獲得響應以返回有效的JSON？
jQuery代碼：
$(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的代碼：
[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;
}
}
XHR對象從Web服務調用返回：
xhr: Object
abort: function (statusText) {
always: function() {
complete: function() {
done: function() {
error: function() {
fail: function() {
getAllResponseHeaders: function() {
getResponseHeader: function (key) {
overrideMimeType: function (type) {
pipe: function (/* fnDone, fnFail, fnProgress */) {
progress: function() {
promise: function (obj) {
readyState: 4
responseText: "{"d":"[{\"id\":\"10499\",\"label\":\"Delmar,AL (35551)\",\"value\":\"Delmar,AL (35551)\"},{\"id\":\"2679\",\"label\":\"Delmar,DE (19940)\",\"value\":\"Delmar,DE (19940)\"},{\"id\":\"2401\",\"label\":\"Delmar,IA (52037)\",\"value\":\"Delmar,IA (52037)\"},{\"id\":\"2679\",\"label\":\"Delmar,MD (21875)\",\"value\":\"Delmar,MD (21875)\"},{\"id\":\"3584\",\"label\":\"Delmar,NY (12054)\",\"value\":\"Delmar,NY (12054)\"},{\"id\":\"4780\",\"label\":\"Delmita,TX (78536)\",\"value\":\"Delmita,TX (78536)\"},{\"id\":\"3352\",\"label\":\"Delmont,NJ (08314)\",\"value\":\"Delmont,NJ (08314)\"},{\"id\":\"11550\",\"label\":\"Delmont,PA (15626)\",\"value\":\"Delmont,PA (15626)\"},{\"id\":\"4574\",\"label\":\"Delmont,SD (57330)\",\"value\":\"Delmont,SD (57330)\"}]"}"
setRequestHeader: function (name, value) {
state: function() {
status: 200
statusCode: function (map) {
statusText: "OK"
