I'm trying to get the jQuery Automcomplete thing to work, but it wont do as i want :P This is my code:

JavaScript的：

JavaScript:

        $("#CustomerID").autocomplete({
            source: function(request, response) {
                $.ajax({
                    type: "POST",
                    url: "/customer/search",
                    dataType: "json",
                    data: {
                        term: request.term
                    },
                    error: function(xhr, textStatus, errorThrown) {
                        alert('Error: ' + xhr.responseText);
                    },
                    success: function(data) {
                        response($.map(data, function(c) {
                            return {
                                label: c.Company,
                                value: c.ID
                            }
                        }));
                    }
                });
            },
            minLength: 2,
            select: function(event, ui) {
                alert('Select');
            }
        });

ASP MVC：

ASP MVC:

    [AcceptVerbs(HttpVerbs.Post)]
    public JsonResult Search(string term)
    {
        if (term == null)
            term = "";

        List<JSON_Customer> customers = repCustomer.FindCustomers(term).ToList();
        return Json(customers);
    }

    public class JSON_Customer
    {
        public int ID { get; set; }
        public string Company { get; set; }
    }

    public IQueryable<JSON_Customer> FindCustomers(string searchText)
    {
        return from c in _db.Customers
               where c.Company.Contains(searchText)
               orderby c.Company
               select new JSON_Customer
               {
                   ID = c.ID,
                   Company = c.Company
               };
    }

我从 $请求。AJAX ，我根据搜索词回报客户的正确列表。和成功方法被调用。我可以看到数据有一个 [对象的对象] 的价值，但我该怎么做？没有客户在我的下拉列表。我使用了响应（$。地图... code从的 http://jqueryui.com/demos/autocomplete/#remote-jsonp ，但它只是不会工作。

I get the request from $.ajax and I return the correct list of customers according to the search term. And the success method is invoked. I can see that data has a [object Object] value but what do I do next? No customers drops down in my list. I'm using the response($.map... code from the http://jqueryui.com/demos/autocomplete/#remote-jsonp but it just wont work.

任何人都知道为什么吗？

Anyone know why?

推荐答案

我我的第一个AJAX请求前使用此 - 我敢打赌，这将有助于。定义标准的项目，并采取了D的保健属性把微软作为顶级属性。

I use this before my first AJAX request -- I bet it will help. Defines the standard items and takes care of the "d" attribute microsoft puts in as the top level attribute.

  $.ajaxSetup({
     type: "POST",
     contentType: "application/json; charset=utf-8",
     data: "{}",
     dataFilter: function(data) {
        var msg;

        if (typeof (JSON) !== 'undefined' && typeof (JSON.parse) === 'function')
           msg = JSON.parse(data);
        else
           msg = eval('(' + data + ')');

        if (msg.hasOwnProperty('d'))
           return msg.d;
        else
           return msg;
     }
  });
