我阅读了如何将自定义 JS 文件添加到新的 Rails 7 项目并且我写了Rails 7：如何添加自定义 javascript 函数？ 我想现在我已经清楚了。
我不想加载模块。我只想加载一个带有一些像这样的自定义函数的 JavaScript 文件。
function btn_project_show() {
alert('culodemono');
}
使用此代码...（以及上面帖子中提到的所有其他内容）
<%= javascript_importmap_tags %>
rails 创建此代码...（我知道 importmap 意味着源是一个 javascript 模块，而不是具有简单功能的简单文件）

否则，我的简单javascript函数找不到。
将其添加到您的布局中：
<%= javascript_include_tag "custom/index" %>
不要将该文件导入到其他任何地方，并从 importmap.rb 中删除它的
pin请记住，您仍然可以使用模块创建函数，只需将它们设为全局即可在模块外部使用：
window.btn_project_show = function() {
alert('culodemono');
}
