typeahead.js无法从asp.net中的远程数据源获取数据

Question

我试图在asp.net web forms app中实现typeahead.js。

我有一个通用的处理程序，它返回字符串列表，在我的例子中，是学校名称。

这是处理程序的代码：

   public void ProcessRequest(HttpContext context)
        {
            List<string> strSchools = new List<string>();
            string prefixText = context.Request.QueryString["q"];
            var schools =
               DataLayer.GetSchools()
                   .Select(s => s).OrderBy(s => s.Name);

            foreach (SchoolItem school in schools)
            {
                if (prefixText != string.Empty)
                {
                    prefixText = prefixText.ToLower();
                    if (school.Name.ToLower().Contains(prefixText))
                    {
                        strSchools.Add(school.Name);
                    }
                }
                else
                {
                   strSchools.Add(school.Name);
                }
            }

            JavaScriptSerializer jsSerializer = new JavaScriptSerializer();

            context.Response.Write(jsSerializer.Serialize(strSchools));
        }

在js代码中我有这个：

  function pageLoad(sender, args) {

            var schoolList = new Bloodhound({
                datumTokenizer: Bloodhound.tokenizers.obj.whitespace('names'),
                queryTokenizer: Bloodhound.tokenizers.whitespace,
                limit: 10,
                remote: 'SchoolListHandler.ashx'
            });

            // kicks off the loading/processing of `local` and `prefetch`
            schoolList.initialize();
            // debugger;

            // passing in `null` for the `options` arguments will result in the default
            // options being used
            $('#txtSchool').typeahead(null, {
                name: 'name',
                displayKey: 'Name',
                // `ttAdapter` wraps the suggestion engine in an adapter that
                // is compatible with the typeahead jQuery plugin
                source: schoolList.ttAdapter()
            });
  }

由于某些原因，我说我无法到达处理程序并获得结果。

你知道有什么不对吗？
