Question

如果字符串看起来是有效的JSON格式（从api调用接收），我该如何解析该字符串以便我可以访问

JSON.parse（data）的值返回为包含[Object]的JSON，这对我没有帮助。
我正在尝试将data中的lat和lng作为字符串发送给我，我认为可以转换为JSON。
我知道我可以将data作为字符串混乱，但我想将它用作JSON。

{ results: 
   [ { address_components: [Object],
       formatted_address: 'Google Bldg 41, 1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA',
       geometry: [Object],
       place_id: 'ChIJxQvW8wK6j4AR3ukttGy3w2s',
       types: [Object] } ],
  status: 'OK' }

以下是数据的价值：

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "Google Building 41",
               "short_name" : "Google Bldg 41",
               "types" : [ "premise" ]
            },
            {
               "long_name" : "1600",
               "short_name" : "1600",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "Amphitheatre Parkway",
               "short_name" : "Amphitheatre Pkwy",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Mountain View",
               "short_name" : "Mountain View",
               "types" : [ "locality", "political" ]
            },
            {

               "short_name" : "Santa Clara County",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "California",
               "short_name" : "CA",

你可以像这样得到lat和lng：

parsedData = JSON.parse(data);
lat = parsedData.results[0].geometry.location.lat;
lng = parsedData.results[0].geometry.location.lng;

console.log（JSON.parse（result））打印[Object]我期望看到JSON
