我发现这个 javascript 允许您选择一个选项，然后单击“执行”按钮。它会将您重定向到另一个网站。我尝试修改它，以便我可以使用按钮而不是 radio 来使用它，但它似乎不起作用。任何人1都可以帮我吗？

非常感谢。

这里是代码:

最佳答案

您可以在单选按钮上使用 onclick 事件: http://www.dyn-web.com/tutorials/forms/radio/onclick-onchange.php

您可以修改代码以使用按钮而不是单选按钮。它应该类似于以下内容:

   <button  name="b1" onclick="f19_SetFormCookie('Baseball')">Baseball</button>
   <button  name="b2" onclick="f19_SetFormCookie('Basketball')">Basketball</button>
   <button  name="b3" onclick="f19_SetFormCookie('Soccer')">Soccer</button>
   <button  name="b4" onclick="f19_SetFormCookie('Fencing')">Fencing</button>

然后您必须修改 SetFormCookie 函数以接受参数 - 基于将设置的 cookie。
