    if(typeof obj !== 'object'){
        return;
    } else if(window.JSON){
        str = JSON.stringify(obj), //系列化对象
        newobj = JSON.parse(str); //还原
    } else {
        for(var i in obj){
            newobj[i] = typeof obj[i] === 'object' ? 
            cloneObj(obj[i]) : obj[i]; 
        }
