js跳出iframe

(1)session过期后登陆页面跳出iframe页面问题登陆页面增加javascript：function window.onload(){if(window.parent.length>0)window.parent.location=location;}或者：if (window != top){top.location.href = location.href;}(2)自动跳出iframe的代码<script type="text/javascript">if (top.location !== self.location) {top.location=self.location;}</script>(3)在框架页内的退出操作：<script type="text/javascript">if (top.location !== self.location) {top.location = "../index.jsp";//跳出框架，并回到首页}</script>
