我有index.php哪个调用url.php按钮单击ajax以加载而无需重新加载页面。现在在'url.php' 上有另一个data.php通过ajax 调用的按钮。
现在会发生什么：index.php首先打开并单击它的按钮index.php 时加载url.php而不加载页面。但是当我单击按钮Fire me时，url.php它会重定向到data.php
如果我直接打开url.php，那么它会执行 ajax 操作并加载 data.php而无需重新加载页面。
我应该在这里进行什么更改，以便：当我首先打开index.php并单击它的按钮时，它会在url.php不重新加载页面的情况下加载（这已经发生，下一步会出现问题）。之后，当我单击“url.php”上的按钮时，它应该data.php在没有页面加载的情况下加载。

底线是：创建 ajax/jquery 系统 index.php -> url.php -> data.php。现有index.php -> url.php和url.php -> data.php
