javascript - 自动完成选择未触发

Question

我的 asp.net MVC razor View 中有以下脚本:-

$("#Technology2_Tag").autocomplete({
            minLength: 1, delay: 1000,
            source: function (request, response) {
                $.ajax({
                    url: "@Url.Content("~/Switch/AutoComplete2")",
                    dataType: "json",

                    data: {
                        term: request.term,
                        SearchBy: $("#ChoiceTag").prop("checked") ? $("#ChoiceTag").val() : $("#ChoiceName").val(),
                    },
                    success: function (data) {
                        response(data);
                    },
                    select: function (event, ui) 
                    {
                        //get the value user selected
                        alert('t');
                        //your code populate data to dropdownlist...
                    }
                });
            },

        });

自动完成功能运行良好，但选择未触发，例如选择自动完成项后，不会显示任何警报？有人可以建议吗？谢谢

放在ajax里面是错误的，放在外面像这样:

$("#Technology2_Tag").autocomplete({
            minLength: 1, 
            delay: 1000,
            source: function (request, response) {
                $.ajax({
                    url: "@Url.Content("~/Switch/AutoComplete2")",
                    dataType: "json",

                    data: {
                        term: request.term,
                        SearchBy: $("#ChoiceTag").prop("checked") ? $("#ChoiceTag").val() : $("#ChoiceName").val()
                    },
                    success: function (data) {
                        response(data);
                    }

                }); // <----------ending of ajax 
            }, //<------- ending bracket of source function
            select: function (event, ui) 
                    {
                        //get the value user selected
                        alert('t');
                        //your code populate data to dropdownlist...
                    }

        });
