使用属性搜索 json 对象并获取该对象的所有相应属性

Question

我有一个 json 数组，其中包含具有属性产品 ID 的对象。我能够获取产品 ID 并将其存储在一个数组中，并使用产品 ID 填充搜索框。现在，在从搜索框中选择产品 ID 时，该对象的相应纬度和经度属性需要存储在一个数组中。任何人都可以提出一种方法来做到这一点吗？下面是我获取 json 数据并使用产品 ID 填充搜索框的代码。

function loadsearch(){

     $.ajax({
        type: "GET",
        url: 'data.json',
        dataType: "json",
        crossDomain: true,
        success: function parse(response){
 for(k=0;k<response.BMS.length;k++){
productids.push(response.BMS[k].prodid)
     // var ci = response.records[i].city;

 }

        }
});
}
loadsearch();
$(function()
                {
                    $( "#searchbox" ).autocomplete({
                        source: productids,
                        select: function(event,ui){
                            var va = ui.item.value;
                           // hos(va);
                            //searchVal(va);
                        }
                    });
                });

下面是我的json：

也许你正在寻找数组的函数映射。这是一个例子：

$.ajax({
    type: "GET",
    url: 'data.json',
    dataType: "json",
    crossDomain: true,
    success: function parse(response){
    productids = response.BMS.map(
        function (p) {
            return p.prodid 
        }
    );
}

例子：

var a = [1, 2, 3, 4];
var b = a.map( function (x) { return x*2; } );
console.log(b); //it shows [2,4,6,8]
