网上引用的：

 function fn(data, pid) {
    var result = [], temp;
    for (var i = 0; i  0) {
                obj.children = temp;
            }
            result.push(obj);
        }
    }
    return result;
}

自己写的

var aaa= [{name:'aaa',id:0},{name:'a',id:1},{name:'b',id:2,pid:1},{name:'c',id:3,pid:1},{name:'d',id:4,pid:2},{name:'e',id:5,pid:2}];

function test(ary,data){

    var data=data?data:(function(ary){
      var tempAry=[];
      for(var i=0,len=ary.length;i0){
     if(data.constructor==Array){
      for(var n=0,lenB=data.length;n
