如何在Rails中使用纯JavaScript进行删除和确认？

Question

I don't have jquery_ujs in my project, So I am trying to get a pop up when clicked on a delete button.

But the item is getting deleted, even if I press cancel or ok.

Here is the code:

= button_to "Remove Item", item, method: :delete, onclick: 'remove_item()'

function remove_item(event){
    if (!confirm('Are you sure, you want to delete the item')) {
       event.preventDefault();
    }
  }

Can you help me solve this? Thank you.

您必须在onclick属性中传递event ，实际上您只是在使用函数而不传递参数，请尝试：

= button_to "Remove Item", item, method: :delete, onclick: 'remove_item(event)'
