    </li>
    <li>
        item-2
        <ul>
            <li>
                item-2.2
                <ul>

看看这个是不是你想要的

var div=document.createElement('div');
        document.getElementsByTagName('body')[0].appendChild(div);
        var obj=[
            {
                name:"name1",
                age:"age1",
                more:false
            },
            {
                name:"name1",
                age:"age1",
                more:[{
                    name:"name2",
                    age:"age2",
                    more:false
                }]
            },
            {

        (function forEach(obj,div){
            for(var i= 0,len=obj.length;i<len;i++){

                        continue;

                    var li=document.createElement('li');
