Question

我需要将这个json数组映射到文本框并使用自动填充进行填充，下面是我相信正在运行的代码，fiddler返回良好的结果也在控制台浏览器上没有错误

编辑：我在控制台中出错：

未捕获的TypeError：无法读取属性＆＃39;长度＆＃39;未定义的

的jQuery

$(document).ready(function () {
    $(function () {
        $("#destinationhotelcity").autocomplete({
            source: function (request, response) {
                $.ajax({
                    url: "http://engine.hotellook.com/api/v2/lookup.json",
                    dataType: "json",
                    data: {
                        query: request.term, // input field value
                        lang: "en",
                        lookFor: "both",
                        limit: 10,
                    },
                    success: function (data) {
                        response($.map(data.hotels, function (item) {
                            return {
                                label: item.label + ', ' + item.locationName,
                                value: item.label + ', ' + item.locationName,
                                code: item.id
                            }
                        }));
                    }
                });
            },
            select: function (event, ui) {
                $("#destinationhotelcity").val(ui.item.value);
            },
            change: function (event, ui) {
                if (!ui.item) {
                    $("#destinationhotelcity").val("");
                }
            },
            onclick: function (event, ui) {
                $("#destinationhotelcity").val("");
            }
        });
    });
});

Answer 1

response($.map(data.hotels, function (item) {

应该是：

response($.map(data.results.hotels, function (item) {

jQuery ajax自动完成没有映射
