Typeahead将结果显示为undefined

Question

我正在尝试使用typeahead来显示谷歌的建议.

Ajax调用工作正常,数据正确返回:

在执行返回过程(数据)之前; data包含以"w"开头的字符串数组.

data = ["walmart","weather","well fargo","worldstarhiphop","walgreens","维基百科","白页","世界杯","webmd","天气雷达"]

但是显示的建议显示"未定义"而不是真实的单词.知道我在这里缺少什么吗？谢谢.

    <input type="text" class="typeahead" placeholder="Search">


    $('.typeahead').typeahead({
        hint: true,
        highlight: true,
        minLength: 1
    },
    {
        source: function (query, process) {
            $.getJSON("Home/Suggest", { query: query }, function (data) {
                return process(data);
            });
        }
    });

Answer 1

更新:

经过一些研究,我找到了我的问题的答案,如果有人需要,我会在这里发布.

诀窍是 - "进程"回调函数期望结果格式为:

[{value:"string1"},{value:"string2"},{value:"string3"}]

而不只是一个字符串数组.

$('.typeahead').typeahead(
{ hint: true, highlight: true, minLength: 1 }, // options
{
    source: function (query, process) { // source dataset, data = array of strings
        $.getJSON('Home/Suggest', { query: query }, function (data) {
            //data=["string1", "string2", "string3"]
            //process callback function needs it 
            //in a format [{value: "string1"}, {value: "string2"}, {value: "string3"}]
            var output = $.map(data, function (string) { return { value: string }; });
            process(output);
        });
    }
});
