js的一点点见解

var t = {d:'dd','b':'bb',c:{a:function (){alert('dddd');}}};
function test (obj)
{
    this.d='fdfd';
    this.b='dfd';

    var tmp;

//遍历对象

    for(tmp in obj)
    {
        this[tmp]=obj[tmp];
    }
}

var s = new test(t);
alert(s.d);
var x = {c:{a:function (){alert('dxxx');}}};
var s2 = new test(x);
alert(typeof(s2.c.a));
