event.persisted判断是否后退进入

 

后退返回

window.addEventListener(‘pageshow’, function (event) {
if (event.persisted || window.performance &&
window.performance.navigation.type == 2)
{
location.reload();
}
},false);

event.persisted从缓存冲获取时为true否则为false，谷歌浏览器及Ie浏览器不起作用可使用上面的方法判断

 

 <script type="text/javascript">      

        window.addEventListener('pageshow', function (event) {

        if (event.persisted|| window.performance && window.performance.navigation.type == 2){

            document.getElementById("enter").style.opacity=0

            location.reload();

        }

        });

    </script>
