我得到了一个JSON格式的结果,其中object可以在数组中,object可以在object中,或者类似的场景类型中。如何使用JQuery提取数组或对象中的任何特定值。

下面是存储在变量result中的JSON示例。

var result= {
  "to_station": {
    "name": "ANAND VIHAR TERMINAL",

      {
        "name": "FIRST CLASS",

        "code": "FC"
      },
      {
        "name": "FIRST AC",
        "available": "Y",
        "code": "1A"
      },
      {

    {
      "status": "RAC   9/RAC   7",
      "date": "29-8-2018"
    },
    {
      "status": "AVAILABLE-0017",

假设我想提取所有结果日期的状态(内部可用性),我应该如何使用JQuery进行相同的操作。

如果使用jQuery,可以尝试以下操作:

$.each(result.availability, function(idx, data){
    //status is available as data.status
    console.log(data.date + ' ' + data.status);
});

您还可以使用普通javascript实现相同的功能:

for(var idx in result.availability){
    //status is available as result.availability[idx].status
    console.log(result.availability[idx].date + ' ' + result.availability[idx].status);
}

希望这有帮助。
