我有一个表单。上传后转到一个新页面。

现在的问题是如何用户单击浏览器后退按钮后，表单中已被输入的内容依然存在。这样用户就有可能再次单击上伟。导致重复提交和连续提交。

我想问怎么在用户单击后退按钮时表单内容被清空。


回复讨论(解决方案)

在页面 body上加个onload事件，一载入就执行重置表单reset操作



<script> <br /> function reset_form() ｛ <br /> document.getElementById('form1').reset(); <br /> ｝ <br /> </script>



<script> <br /> function reset_form() ｛ <br /> document.getElementById('form1').reset(); <br /> ｝ <br /> </script>

您好
我感觉还是用PHP可靠一点

表单页启用 session 就不保存了

PHP毕竟是后端的语言，可以验证数据是否重复，但页面清空表单还是需要前端来实现的~~

单击后退是浏览器行为，这个时候用js比php靠谱

你所看到的内容是在前端的，所以用JS来处理比较合适

js操作 初始化页面，input 的值被清空。
