可以设置浏览器“退后”时跳转到指定页面吗
可以设置浏览器“后退”时跳转到指定页面吗？
我在某个PHP页面里做了一些操作比如保存数据，然后跳转到另一个页面。可是如果在浏览器中后退时，会后退到先前的那个页面然后操作就重复了。有什么办法避免这个问题吗？
------解决思路----------------------
是可以让浏览器不保存历史的，即使“后退”列表为空，于是名义上阻止了“后退”功能
------解决思路----------------------
开新窗口就可以阻止用户后退了。
------解决思路----------------------
保存数据后用location.replace('新页面');方法跳转即可
