我有一个看起来像这样的对象数组.

var arr = [{'id':21 ,'name' : 'name 1' ,'vehiclename' : 'vehicle 1' ,'parentid' : 21},
           {'id':21 ,'name' : 'name 1' ,'vehiclename' : 'vehicle 2' ,'parentid' : 21},
           {'id':22 ,'name' : 'name 2' ,'vehiclename' : 'vehicle 1' ,'parentid' : 22},
           {'id':22 ,'name' : 'name 2' ,'vehiclename' : 'vehicle 2' ,'parentid' : 22}]

我想对数组进行取消或分组,现在看起来像这样.

var arr = [{'id':21,
             name: 'name 1'
             vehicles : [{'vehiclename':'vehicle 1','parentid':21},
                         {'vehiclename':'vehicle 2','parentid':21}] },
           {'id':22,
             name: 'name 2'
             vehicles : [{'vehiclename':'vehicle 1','parentid':22},
                         {'vehiclename':'vehicle 2','parentid':22}] }
           }]

任何帮助,将不胜感激.
