fullcalendar 中的工具提示不起作用

Question

everyone! I'm trying to show tooltip over events in fullcalendar. But it's not working and show in console this message

Uncaught SyntaxError: Unexpected token (

What can be a problem? This is my js-function code:

$('#calendar').fullCalendar(function() {
    eventAfterRender: function(event, element) {
        $(element).tooltip({
            title: event.title,
            container: "body"
        });
    }
});

Answer 1

In FullCalendar 4, use eventRender function:

eventRender: function (info) {
  $(info.el).tooltip({ title: info.event.title });     
}

Answer 2

You are passing function. You should pass your options and callbacks. Read Docs

$('#calendar').fullCalendar({   //Removed function() from here
    eventAfterRender: function(event, element) {
        $(element).tooltip({
            title: event.title,
            container: "body"
        });
    }
});

Answer 3

as documentation say.

eventRender: function(info) {
    var tooltip = new Tooltip(info.el, {
      title: info.event.extendedProps.description,
      placement: 'top',
      trigger: 'hover',
      container: 'body'
    });
  }

don't forget to import popper.js
