引导程序的模态-单击取消按钮-触发`close（）`或`dismiss（）`吗？

Question

Bootstrap's modal provides two methods to hide the dialog:

close(result) (Type: function) - Can be used to close a modal, passing a result.

dismiss(reason) (Type: function) - Can be used to dismiss a modal, passing a reason.

Is my understanding correct that I should use close when a user clicks on the OK button on the dialog, and dismiss when the user clicks on the cancel button?

Answer 1

Not necessary. A reason can be self-explaintory, like close a modal due a click on a link inside the modal or an event that does not pass between standard "ok || cancel"

Answer 2

Looking at result would indicate that closing is the way to "properly" close a modal, which resolves the result promise.

• result (Type: promise ) - Is resolved when a modal is closed and rejected when a modal is dismissed.`

Judging by that, I would say that you are correct in your assumption.

Answer 3

Consider the case where you have 'Yes', 'No', and 'Cancel'

eg. Preparing to connect to a chatroom, you might ask the user if they want to use their usual nickname, Yes would result in a connection with their nickname, No would result in a connection with a Guest nickname, and Cancel would result in no connection (dismissed)

Cancel is dismissed, yes and no are closed (with a further result)

Of course, there could be many more button combinations, but Yes/No/Cancel is quite common.
