我读了How to add custom JS file to new rails 7 project，我写了Rails 7: How to add custom javascript functions? 我想现在我把事情弄清楚了.
我不想加载模块.我只想加载一个单独的javascript文件，其中包含几个这样的定制函数.
function btn_project_show() {
alert('culodemono');
}
有了这个密码……(以及上面帖子中提到的所有其他事情)
<%= javascript_importmap_tags %>
rails创建此代码...(我理解importmap意味着源代码是一个JavaScript模块，而不是一个简单函数的简单文件)
