如何移动/更改 JavaScript 对象数组 (JSON) 的位置/顺序？

Question

Let's say I have this javascript object array,

[{a:'a', b:2, c:true}, {a:'b', b:3, c:true}, {a:'a1', b:3, false}]

Let's say I need to move the object at index 0 to 2. I have tried this function with no luck.

   Array.prototype.move = function (old_index, new_index) {
    if (new_index >= this.length) {
        var k = new_index - this.length;
        while ((k--) + 1) {
            this.push(undefined);
        }
    }
    this.splice(new_index, 0, this.splice(old_index, 1)[0]);
  };

The object array is not correct, it needs the 'c' variable in the last item:

[{a:'a', b:2, c:true}, {a:'b', b:3, c:true}, {a:'a1', b:3, c:false}];
