創建JSON

Question

我收到下面

{ 
    "category": "test", 
    "sealing_temp_1": "", 
    "sealing_temp_2": "", 
    "sealing_temp_3": "", 
    "level_sensor_1": "", 
    "level_sensor_2": "", 
    "level_sensor_3": "", 
    "check_pack_1": "", 
    "check_pack_2": "", 
    "check_pack_3": "", 
    "comment": "" 
} 

這個JSON數組，我想將其變成這樣的結構，節省

{ 
    "category": "test", 
    "sealing_temp": "['a', 'b', 'c']", 
    "level_sensor": "['x', 'y', 'z']", 
    "check_pack": "[1, 2, 3]", 
    "comment": "" 
} 

有人能指導我，我試圖用for..in但在這個過程

你可能分裂的關鍵，如果它在它的一端有個數字，然後將其用於數組來填補迷路了。

這一提議改變對象，並刪除不想要的性質，這值現在是在收集的陣列。

var object = { category: "test", sealing_temp_1: "s1", sealing_temp_2: "s2", sealing_temp_3: "s3", level_sensor_1: "l1", level_sensor_2: "l2", level_sensor_3: "l3", check_pack_1: "c1", check_pack_2: "c2", check_pack_3: "c3", comment: "cc" }; 
 
    
 
Object.keys(object).forEach(function (k) { 
 
    var parts = k.split(/_(?=\d+$)/); 
 
    if (parts.length === 2) { 
 
     object[parts[0]] = object[parts[0]] || []; 
 
     object[parts[0]][parts[1] - 1] = object[k]; // subtract one for zero based array 
 
     delete object[k]; 
 
    } 
 
}); 
 
console.log(object);

.as-console-wrapper { max-height: 100% !important; top: 0; }
