将整数数组映射到值和选择值的id

// 创建一个空的字典
var mapping = {};

// 将整数数组映射到值和选择值的id
var arr = [1, 2, 3];
for (var i = 0; i < arr.length; i++) {
  var key = arr[i];
  var value = "value" + key;
  var id = "id" + key;
  mapping[key] = {
    value: value,
    id: id
  };
}

// 根据整数查找对应的值和选择值的id
var num = 2;
var result = mapping[num];
console.log(result.value); // 输出"value2"
console.log(result.id); // 输出"id2"
