 ie: /msie/.test(window.navigator.userAgent.toLowerCase()),
 moz: /gecko/.test(window.navigator.userAgent.toLowerCase()),
 opera: /opera/.test(window.navigator.userAgent.toLowerCase())
};

//得到当前浏览器高度
function dbwindowHeight() {
 var E = document.documentElement;
 return self.innerHeight || (E && E.clientHeight) || document.body.clientHeight;
}

//自定义获取对象的函数
fw.$ = function (s) {
 return (typeof s == "object") ? s : document.getElementById(s);
};

//删除子节点的函数
fw.Element = {remove:function () {
 for (var i = 0; i < arguments.length; i++) {
  try {
   fw.$(arguments[i]).parentNode.removeChild(fw.$(arguments[i]));
  }
  catch (e) {
  }
 }
}};

 

//切换弹出层newDiv的导航条
function tab(){
 var obj= document.getElementById("box").childNodes;
 var Arr=[];

  }
