在有效載荷轉換鍵值對，JSON對象

Question

這裏是我的JSON有效載荷

"multiList": [ 
    { 
    "Key": "my_key", 
    "Value": this is my key 
    }, 
    { 
    "Key": "my_text_box", 
    "Value": "This is my text box" 
    }, 

]

我怎麼能動態轉換這個使用jQuery

"multiList": [ 
    { 
    "my_key" : "this is my key" 
    }, 
    { 
    "my_text_box": "This is my text box" 
    }, 

]

Answer 1

例如：

yourobj.multiList = yourobj.multiList.map(function(v) { 
    var r = {}; 
    r[v.Key] = v.Value; 
    return r; 
}); 

如果你想支持IE8，你必須use a shim for map或使用for代替map：

for (var i=0; i<yourobj.multiList.length; i++) { 
    var v = yourobj.multiList[i]; 
    var r = {}; 
    r[v.Key] = v.Value; 
    yourobj.multiList[i] = r; 
}
