--------------------------------------------------------------------------------
9.iframe(嵌入式帧)自适应高度
填写的嵌入地址一定要和本页面在同一个站点上，否则会提示“拒绝访问！”。对跨域引用有权限问题，请查阅其他资料。

document.write( "现在离"+times+"还有: "+time +"天")
</Script>
--------------------------------------------------------------------------------
15.加在HEAD里
