如何把二维数组转化成json对象

Question

 大家知道怎么把二维数组转化成json对象吗
例如
var source = 
[['ID','name','size','parentID'],
              ['0','工厂',13,''],
              ['1','分销站A',13,'0'],    
              ['2','分销站B',13,'0']];
需要转成：
var jsonData = [
{id:'0', name:'工厂',size:13,parentID:''},
{id:'1', name:'分销A',size:13,parentID:'0'},
{id:'2', name:'分销B',size:13,parentID:'0'}
];
