本人写的一个小例子,闲话不说,上代码
var nodes = [
{"id":2,"cname":"第一级1","ipid":0,"ccode":"1"},
{"id":3,"cname":"第一级1","ipid":2,"ccode":"1"},
{"id":4,"cname":"第一级1","ipid":2,"ccode":"1"},
{"id":5,"cname":"第一级1","ipid":4,"ccode":"1"},
{"id":6,"cname":"第一级1","ipid":3,"ccode":"1"},
{"id":7,"cname":"第一级1","ipid":0,"ccode":"1"}
]
function transDate(list,idstr,pidstr){
var result = [],temp = {};
for(i = 0; i < list.length; i++){
temp[list[i][idstr]]=list[i];//将nodes数组转成对象类型
}
for(j=0; j<list.length; j++){
tempVp = temp[list[j][pidstr]]; //获取每一个子对象的父对象
if(tempVp){//判断父对象是否存在,如果不存在直接将对象放到第一层
if(!tempVp["nodes"]) tempVp["nodes"] = [];//如果父元素的nodes对象不存在,则创建数组
tempVp["nodes"].push(list[j]);//将本对象压入父对象的nodes数组
}else{
result.push(list[j]);//将不存在父对象的对象直接放入一级目录
}
}
return result;
}
console.log(transDate(nodes,"id","ipid")); //传入的值 列表 ,本对象的id,父对象的id
document.write(JSON.stringify(transDate(nodes,"id","ipid")));
