我跟着這個職位的方向：how can we integrate jquery autocomplete using asp.net, webservie and sql database我不能讓與AJAX調用自動完成工作，我的web服務
，使jQuery的自動完成插件的工作與我的asp.net web服務，但它只是不會工作。
自動完成工作，如果我做本地數據。我也可以使用jquery ajax調用我的web服務。有人可以告訴我我做錯了什麼嗎？代碼：
//This jquery ajax call works perfectly
function AjaxTest() {
$.ajax({
type: "POST",
url: "/Services/OSServices.asmx/HelloWorld",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: RenderTest
});
}
//this autocomplete ajax call doesn't work. It doesn't even hit the breakpoint in the
web service
$("#lastName").autocomplete("/Services/OSServices.asmx/HelloWorld", {
parse: function(data) {
var parsed = [];
$(data).find("string").each(function() {
parsed[parsed.length] = {
data: [$(this).text()],
value: $(this).text(),
result: [$(this).text()]
};
});
return parsed;
},
datatype: "xml"
});
//this is the webservice code:
[WebService(Namespace = "http://tempuri.org")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.ComponentModel.ToolboxItem(false)]
[System.Web.Script.Services.ScriptService]
public class OSServices : System.Web.Services.WebService
{
[WebMethod]
public string[] HelloWorld()
{
string[] myArray = { "blah1", "blah2", "blah3" };
return myArray;
}
}

這是我得到題爲內部服務器錯誤的響應。

編輯：
所以我刪除了/的HelloWorld /部分來自URL，響應已不產生 錯誤。但是，這並不能解決我的問題。我想有另一種 的方式來傳遞方法名稱來調用？
好吧，我們需要更多的信息，如顯示正在發出的請求和任何響應以及狀態碼和響應內容的Fiddler或Firebug屏幕截圖。 – redsquare 2009-09-02 17:13:02
我已將響應與錯誤一起添加。謝謝。 – Riz 2009-09-02 17:44:43
