我用CSS设计的吨可以使用吗？或者我必须替换这些按钮吗？您只需更新它们链接到的位置。href=“#我的链接”将改为“download.php？file=myfile”。谢谢@Aaron Brewer。让我看看你给我的链接。非常感谢。虽然我对PHP并没有什么想法，但我肯定会尝试一下。我想我从你的台词中得到了一点启示“如果你想做这样的事情，那么一个非常简单的解决方案就是给每个下载按钮一个唯一的ID；让下载计数器作为一个简单div中的数字”！让我试着从头开始。再次非常感谢。非常感谢：））很抱歉在您吃饭时打扰了您：（如果需要的话，我可能会详细介绍答案，因为答案不太清楚；但正如我所说的，PHP中的mysql函数有一些非常好的教程和文档！考虑到这一点，实际上下载计数器不必是div，jQuery也可以编写任何元素！（这是很多可能性！）我觉得这比担心HTML代码中有内联PHP要好。不过，我肯定会选择jQuery和PHP解决方案，它应该很容易装配！而且，如果你掌握了它，它会打开很多门……晚餐也不太好！；）如果您进一步阐述关于jQuery的观点，我将不胜感激。我已经介绍了jQuery代码的第一部分，以演示如何在组（即类）中的每个元素上循环，然后为该元素创建.post（）请求；从PHP脚本返回值。：）不幸的是，我所做的每一次编辑似乎都让它听起来更加复杂和混乱！我又编辑了一遍，我能理解你的感受。我第一次看到jQuery（我对Javascript非常了解）时，我记得我在想“这个不断出现的美元符号到底是什么？！”-但一旦你习惯了它，它就会非常强大和简单。我仍然认为你最好的选择是做这样的事情；如果只为满足和技能你可以使用一次又一次！另外，使用stackoverflow，您永远不会出错；）
