Jquery ui 如何使用jquery自动完成从json文件获取值

这是我的jquery代码

$（'.typeahead'，此）。自动完成({

我的Json文件是 [ { “代码”：“9BP3”， “名称”：“9Bp No3” }, { “代码”：“AA”， “名称”：“共济失调” },{ “代码”：“BILA”， “名称”：“贝斯拉纳” }, { “代码”：《图片报》， “名称”：“比尔迪” },{ “代码”：“HRI”， “名称”：“Hardoi” }, { “代码”：“人力资源管理”， “姓名”：“Hadmadiya” } ]

当我键入任意三个字母时，它将返回整个json文件值

q:request.term这是从stations.json中筛选返回值的字符串。您必须将类似这样的变量传递给筛选结果。stations.json必须是动态生成的文件，如带有json头的php。q是$\u GET参数，必须进行解析。请尝试如下更改代码：

$.ajax({
  url: "includes/stations.json",
  dataType: "json",
  data: {
    q: request.term // here is the string for filter returned values from stations.json. You must pass variable like this to filter results. stations.json must be dynamically generated file like php with json header. q is $_GET parameter and must be parsed.
  },
  success: function(data) {
    response(
        $.map(data, function(item, i) {
            return {
                label: item.name,
                value: item.code
            }
        })
    );
}
});
},
minLength: 3,

$.ajax({

                value: item.code
            }
        })
    );
}
});
},
