如何避免重复提交表单页

互联网 2021-08-14 20:39:10 10 6,483

在很多表单提交数据的网站中，很容易遇到用户通过浏览器的后退按钮，返回表单提交前的页面，然后多次提交表单的情况。

为了避免提交重复数据，可以使用JavaScript在网页的头部head标签内添加一段简单的代码，禁止浏览器记录历史记录。

JavaScript:window.history.forward(1);

然后，即可禁止浏览器记录上一页的历史记录，防止用户重复提交。

    Having read this I thought it was extremely informative. I appreciate you spending some time and effort to put this content together. I once again find myself spending way too much time both reading and posting comments. But so what, it was still worthwhile!

    Hi there would you mind stating which blog platform you're working with? I'm planning to start my own blog in the near future but I'm having a difficult time selecting between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your layout seems different then most blogs and I'm looking for something unique. P.S My apologies for getting off-topic but I had to ask!

    Do you have a spam problem on this blog; I also am a blogger, and I was wondering your situation; many of us have developed some nice methods and we are looking to swap techniques with other folks, why not shoot me an e-mail if interested.
