Javascript或Ruby。格式化JSON對象

Question

我需要把這個JSON對象：

[ 
    [ 
     "email@email.com" 
    ], 
    [ 
     "email2@email.com" 
    ], 
    [ 
     "email3@email.com" 
    ], 
    [ 
     "email4@email.com" 
    ] 
] 

進入這個：

{ 
    "data": [ 
     { 
      "email": "email@email.com" 
     }, 
     { 
      "email": "email2@email.com" 
     }, 
     { 
      "email": "email3@email.com" 
     }, 
     { 
      "email": "email4@email.com" 
     } 
] } 

這是如何完成的？

Answer 1

那麼，這實際上只是一個數組的數組，但除此之外。只是通過數組的數組循環，推動相關數據到新的數組中的對象：

var my_new_object = {}; 
my_new_object['data'] = []; 

for (var i = 0; i < your_array.length; i++) { 
    my_new_object.data.push({"email": your_array[i][0]}); 
} 

Working demo。

Answer 2

的Javascript：

var original = [ 
[ 
    "email@email.com" 
], 
[ 
    "email2@email.com" 
], 
[ 
    "email3@email.com" 
], 
[ 
    "email4@email.com" 
] 
]; 

var output = {}; 
output.data = new Array(); 
for(var i=0;i<original.length;i++){ 
    var o = new Object(); 
    o.email = original[i][0]; 
    output.data.push(o); 
}

你可以在這裏進行測試： http://jsfiddle.net/v3fnk/

var data=[["email@email.com"],["email2@email.com"],["email3@email.com"],["email4@email.com"]]; 

for (var i in data) { 
    for (var x in data[i]) { 
     $("#info").append(data[i][x] + '<br/>'); 
    } 

}
