Javascript/PHP 重定向

各位程序员大家好!

我正在做一个个人项目(主要是为了学习 php/javascript)，在点击链接时遇到了重定向问题。我在创建的标签页上遇到了一些奇怪的情况，我认为这可能是导致我出现问题的原因。

我试图让用户点击(由于 css 使它看起来与正常情况不同)将他们重定向到包含更多详细信息的新页面。我认为我页面上的第二个标签让我失望，因为我在其中有一个表单。

我已经尝试了很多不同的东西，比如 window.location.href="", location.href="", document.location="", 等等...但同样的事情总是发生。我能够收到这两条警报消息，所以我知道我正在进入我的 JavaScript(即使我将它放入它自己的 .js 文件中)。

无论如何，建议/帮助都会很有帮助。此外，如果有人建议稍微清理一下这段代码，那也会很有帮助。

下面基本上是我所拥有的。

预先感谢您的帮助!

最佳答案

window.location.href 在某些浏览器和情况下可能不会触发重新加载。您应该在之后添加一个重新加载

像这样:

window.location.href = '/foo/bar/';
window.locaton.reload(true)

但是，某些浏览器会延迟几毫秒来执行 location.href 设置。在这种情况下，window.location.reload(true) 可能在此之前完成。

因此，在reload中加入超时时间:

window.location.href = '/foo/bar/';
setTimeout('window.locaton.reload(true)', 500);

适用于我所有的浏览器
