如何將數組平鋪或旋轉到單個對象？

Question

我有幾個陣列我想扁平化爲一個對象。任何人都可以看到一個很好的方式來映射或從這轉移數據：

Something: [ 
    {"Test":0,"Count":206,"Abc":0}, 
    {"Test":2,"Count":119,"Abc":3}, 
    {"Test":1,"Count":207,"Abc":3}, 
    {"Test":3,"Count":129,"Abc":8, 
    {"Test":4,"Count":122,"Abc":2} 
] 

to this？

{ 
    Name: "Something", 
    Test0: 206, 
    Test1: 207, 
    Test2: 119, 
    Test3: 129, 
    Test4: 122 
} 

Answer 1

Array.prototype.flattenOn=function(out,key,value) 
{ 
    for(var i=0,l=this.length;i<l;i++) 
    { 
     out[key+''+this[i][key]]=this[i][value]; 
    } 
    return out; 
}; 

var obj={ 
    Something:[ 
    {"Test":0,"Count":206,"Abc":0}, 
    {"Test":2,"Count":119,"Abc":3}, 
    {"Test":1,"Count":207,"Abc":3}, 
    {"Test":3,"Count":129,"Abc":8}, 
    {"Test":4,"Count":122,"Abc":2} 
    ] 
}; 

var output={}; 
output.Name='Something'; 
output=obj.Something.flattenOn(output,'Test','Count'); 
alert(JSON.stringify(output));

Answer 2

var newSomething = {}; 
newSomething.name = 'Something'; 
for (var i=0,l=Something.length;i<l;i++) { 
    newSomething['Test'+Something[i].Test] = Something[i].Count; 
}
