Question

如何將以下json轉換爲所需格式？

我有什麼：

{ 
    "1":{ 
    "name":"Room1", 
    "agegroup":"38 to 67", 
    "display_agegroup":"Months", 
    "0":"After School Care" 
    }, 
    "5":{ 
    "name":"new room", 
    "agegroup":"3.08 to 4.", 
    "display_agegroup":"Years", 
    "0":"After School Care", 
    "1":"Before School Care" 
    } 
} 

我需要什麼：

[{ 
    "id":"1", 
    "field1":"Room1", 
    "field2":"38 to 67", 
    "field3":"Months", 
    "field4":"After School Care"}, 
{ 
    "id":"5", 
    "field1":"new room", 
    "field2":"3.08 to 4.", 
    "field3":"Years", 
    "field4":"After School Care & Before School Care" 
}] 

請指引我。

Answer 1

var out = []; 
var input = { 
    "1": { /* ... */ }, 
    "5": { /* ... */ } 
}; 

_.each(_.keys(input), function(el) { 
    var obj = { 
    "id": el 
    }; 

    _.each(_.keys(input[el], function(k, idx) { 
    obj["field"+(1+idx)] = input[el][k]; 
    }); 

    out.push(obj); 
}); 

爲了方便起見，使用Underscore.js。如果你不能/不會，那麼用標準的JS代碼代替_.keys和_.each是相當簡單的。
