我正在开发 Rails 3 应用程序。这里有一个视图显示用户上传的所有 excel 文件。执行所有复选框选定文件的按钮已经存在，每个文件分别删除。现在我应该添加一个“删除”按钮来删除选定的文件。我添加了按钮 n 修改了此表单调用的函数，现在只是显示“执行中”和“删除中”，以检查第二个“删除”按钮是否具有功能。但是每次单击删除时，它仅在 cmd 中打印“执行中”。我猜想在视图“列表”中编写的 AJAX 相关代码是问题所在。请帮忙！！告诉我为什么它总是会执行？相关代码在这里：
PS：我在controller.rb中也使用过if params[:commit]="Delete"& if params[:delete_button]，但没有帮助
list.html.erb（显示所有文件的视图）
