如何在JavaScript中放置另一个JSON数据

如何解决如何在JavaScript中放置另一个JSON数据

我正在构建 laravel 刀片php文件。 我需要为日历计划制作 json数据。 但是我不能将每个数据放入json。 此结果来自所有相同的记录。

代码如下...

@foreach($room_rates as $key=>$room_rate)
  var roomRate_object = {
    id: "{{$room_rate->sup_hotel_room_rates_list_id}}",roomRate_name: "{{$room_rate->room->room_name}}",roomRate_nameCode: "{{$room_rate->sup_room_details_id}}",roomRate_type: "2",roomRate_value: "3",start: "{{$room_rate->from_date}}",end: "{{$room_rate->to_date}}",status: "{{$room_rate->status}}",allotmant: "function select(arr,obj) {
    return arr.reduce(function (acc,key) {
        if (key in obj) acc[key] = obj[key];
        return acc;
    },{});
}

const arr = ['a','c','e'];
const obj = { a: 1,b: 2,c: 3,d: 4 };

let output = select(arr,obj);
console.log(output); // --> { a: 1,c: 3 }",night_stayval: "{{$room_rate->min_night_stay}}",};
  console.log("kkk roomRate_object")
  console.log(roomRate_object)
  
  roomRate_object.id = roomRate_object.id + "1";
  roomRate_object.roomRate_type = "1";
  roomRate_object.roomRate_value = "{{$room_rate->adult_rate}}";
  realize_schedule.push(roomRate_object);

  roomRate_object.id = roomRate_object.id + "2";
  roomRate_object.roomRate_type = "2";
  roomRate_object.roomRate_value = "{{$room_rate->double_rate}}";
  realize_schedule.push(roomRate_object);

  roomRate_object.id = roomRate_object.id + "3";
  roomRate_object.roomRate_type = "3";
  roomRate_object.roomRate_value = "{{$room_rate->triple_rate}}";
  realize_schedule.push(roomRate_object);

  roomRate_object.id = roomRate_object.id + "4";
  roomRate_object.roomRate_type = "4";
  roomRate_object.roomRate_value = "{{$room_rate->quad_rate}}";
  realize_schedule.push(roomRate_object);

  roomRate_object.id = roomRate_object.id + "5";
  roomRate_object.roomRate_type = "5";
  roomRate_object.roomRate_value = "{{$room_rate->child_rate}}";
  realize_schedule.push(roomRate_object);
@endforeach

结果是这样的。 enter image description here

那很奇怪。 请帮助我。

我对此非常担心。 谢谢您的时间。

解决方法

我认为您对参考的更改有些困惑。在javascript中，当创建对象时，如果您尝试修改该对象的值，则它将更改内存中的值。例子

var obj = {name:'test'};
var b = obj;
b.name = 'test2';

如果您对输出进行控制台，则obj和b都将具有test2，因为javascript将更改内存中的值，如var b = obj上的行一样，它只是使b指向obj使用的同一内存。 / p>

为逃避此技术，我们根据需要使用深克隆或浅克隆。

您有很多选择，一个可以只是创建多个具有不同名称的对象。

用于制作新对象

function getObj($room_rate,id,type,value){
  return {
   id: "{{$room_rate->sup_hotel_room_rates_list_id}}"+ id,roomRate_name: "{{$room_rate->room->room_name}}",roomRate_nameCode: "{{$room_rate->sup_room_details_id}}",roomRate_type: type,roomRate_value: value,start: "{{$room_rate->from_date}}",end: "{{$room_rate->to_date}}",status: "{{$room_rate->status}}",allotmant: "realize_schedule.push(getObj($room_rate,"1","{{$room_rate->adult_rate}}"));
",night_stayval: "{{$room_rate->min_night_stay}}",}
}

创建上述功能

并称呼它

\pause

以上片段仅是一个示例，仅用于说明您如何解决问题的想法

,

您必须为此使用每个对象。

var roomRate_object = {
    id: "{{$room_rate->sup_hotel_room_rates_list_id.'1'}}",roomRate_type: "1",roomRate_value: "{{$room_rate->adult_rate}}",allotmant: "/p:PublishUrl="C:\Apps\"
",};
realize_schedule.push(roomRate_object);

var roomRate_object = {
    id: "{{$room_rate->sup_hotel_room_rates_list_id.'2'}}",roomRate_type: "2",roomRate_value: "{{$room_rate->double_rate}}",allotmant: "/p:PublishUrl="C:\\Apps\\"
",};
realize_schedule.push(roomRate_object);

var roomRate_object = {
    id: "{{$room_rate->sup_hotel_room_rates_list_id.'3'}}",roomRate_type: "3",roomRate_value: "{{$room_rate->triple_rate}}",allotmant: "is_writable($directory_path)",};
realize_schedule.push(roomRate_object);

,

您必须使用另一个对象将另一个数据放入json。 因此，请执行以下代码。 我为你做的。

@foreach($room_rates as $key=>$room_rate)
  @for ($i = 1; $i <= 5; $i++)
    var roomRate_object = {
    id: "{{$room_rate->sup_hotel_room_rates_list_id}}",roomRate_type: "{{$i}}",roomRate_value: "3",allotmant: "=IF(AND(M2<=TODAY();L2="");"ERROR";"OK")
",};

  @switch($i)
    @case(1)
        roomRate_object.roomRate_value = "{{$room_rate->adult_rate}}";
        @break

    @case(2)
        roomRate_object.roomRate_value = "{{$room_rate->double_rate}}";
        @break

    @case(3)
        roomRate_object.roomRate_value = "{{$room_rate->triple_rate}}";
        @break

    @case(4)
        roomRate_object.roomRate_value = "{{$room_rate->quad_rate}}";
        @break

    @case(5)
        roomRate_object.roomRate_value = "{{$room_rate->child_rate}}";
        @break

    @default
        <span>Something went wrong,please try again</span>
  @endswitch

  realize_schedule.push(roomRate_object);
  @endfor
  console.log("kkk roomRate_object")
  console.log(roomRate_object)
  
@endforeach

我用另一个对象输入json数据。

如果结果不正确，请告诉我。 我会花我的黄金时间为您服务。 真幸运。
