急急急！！！怎样将json数组数据 转成json树结构数据？
现有数据：{success:true,root:[{id:"001",name:"aaa",parent:null},{id:"002",name:"bbb",paren...
现有数据：
{success:true,root:[
{id:"001",name:"aaa",parent:null},
{id:"002",name:"bbb",parent:null},
{id:"003",name:"ccc",parent:"001"},
{id:"004",name:"ddd",parent:"001"},
{id:"005",name:"eee",parent:"002"},
{id:"006",name:"fff",parent:"003"}

怎样将上面的数据转成如下的格式：
{success:true,root:[
{id:"001",name:"aaa",text:"aaa",leaf:false,children:[
{id:"003",name:"ccc",text:"ccc",leaf:false,children:[
{id:"006",name:"fff",text:"fff",leaf:true}
]},
{id:"004",name:"ddd",text:"ddd",leaf:true}
]},
{id:"002",name:"bbb",text:"bbb",leaf:false,children:[
{id:"005",name:"eee",text:"eee",leaf:true}
