排序JSON字典字母顺序值

问题描述：

我已经字典下列字典，我因为我没有权力在服务器端使用这种格式排序JSON字典字母顺序值

{"1":{"aov":0,"oo":1,"ot":"Cem-Merve","pi":87},"2":{"aov":100,"oo":2,"ot":"Murat-Pelin","pi":88},"3":{"aov":0,"oo":3,"ot":"Fevzi-Azbiye","pi":85},"4":{"aov":0,"oo":4,"ot":"Burak-Gizem","pi":86},"21":{"aov":100,"oo":21,"ot":"Murat","pi":84,"ro":2},"22":{"aov":0,"oo":22,"ot":"Pelin","pi":83,"ro":2}}

我需要它使用JavaScript通过按键按字母顺序排序要像

{"1":{"aov":0,"oo":1,"ot":"Cem-Merve","pi":87},"2":{"aov":100,"oo":2,"ot":"Murat-Pelin","pi":88},"21":{"aov":100,"oo":21,"ot":"Murat","pi":84,"ro":2},"22":{"aov":0,"oo":22,"ot":"Pelin","pi":83,"ro":2},"3":{"aov":0,"oo":3,"ot":"Fevzi-Azbiye","pi":85},"4":{"aov":0,"oo":4,"ot":"Burak-Gizem","pi":86}}

我已经试过类似的东西，但是没有希望：

function sortObject(o) { 
    var sorted = {}, 
    key, a = []; 

    for (key in o) { 
     if (o.hasOwnProperty(key)) { 
      a.push(key); 
     } 
    } 

    a.sort(); 

    for (key = 0; key < a.length; key++) { 
     sorted[a[key]] = o[a[key]]; 
    } 
    return sorted; 
}

任何想法如何执行该操作？

的JavaScript将是一个良好的开端。尝试一下，当你卡住时回复。 – crush

我被卡住了，这就是为什么我问这个 – ImadBakir

JavaScript对象不可排序，您需要将它转换为Array，然后使用Array.prototype.sort对项目进行排序。 –

答

正如其他人在评论中指出的，一个对象的属性不能被排序。你可以做的是产生一个对象属性的有序数组，并迭代该数组以访问你想要的对象属性。你基本上已经在你的示例代码中做了这个 - 你只是试图把它做得太过分了。

See jsFiddle

function getObjectKeysAlphabetical(obj) { 
    var keys = [], 
     key; 

    for (key in obj) { 
     if (obj.hasOwnProperty(key)) 
      keys.push(key); 
    } 

    keys.sort(); 

    return keys; 
} 

var obj = {}; //Your object here. 
var keys = getObjectKeysAlphabetical(obj) 
    i = 0, key = null, val = null; 

//Iterate the array of sorted keys. 
for (i = 0; i < keys.length; i++) { 
    key = keys[i]; 
    val = obj[key]; //Get the value of the property here. 
}

工作像一个魅力与一些编辑，以符合我的要求，非常感谢主意。 – ImadBakir
