Show a Bootstrap popup and then revert the eventDrop in FullCalendar based on user's choice

问题

Currently I am using Javascript confirm box to ask whether the user wants to proceed or he wants to revert, but I need to warn the user using Bootstrap popup. User needs to say 'Proceed/Cancel' in popup.

I used bootstrap modal popup. but the 'drop' doesn't wait for user's choice. It executes the flow of code written inside 'eventDrop', before user clicks yes/no button of popup.

Current code snippet:

eventDrop: function(event, delta, revertFunc) {
        if (!confirm("Are you sure to re-book the ticket?"))
            revertFunc();
}

Kindly suggest.

回答1:

Sometimes in eventDrop function if not work if { } not given. So, please follow my code below::

eventDrop: function(event, delta, revertFunc) {
    if (!confirm("Are you sure to re-book the ticket?")) {
      revertFunc();
    }
}

But it will be better to use a confirmbox or bootstap cofirm modal because if any user checks prevent this page from additional dialogs , from next time that alert box will not show.
