表单
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。
------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
------解决方案--------------------



<script><br /> function reset_form() {<br /> document.getElementById('form1').reset();<br />}<br /></script>
------解决方案--------------------
表单页启用 session 就不保存了
------解决方案--------------------
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~~
------解决方案--------------------
单击后退是浏览器行为,这个时候用js比php靠谱
------解决方案--------------------
你所看到的内容是在前端的,所以用JS来处理比较合适
------解决方案--------------------
js操作 初始化页面,input 的值被清空。
