如果开始与结束日期相同，则为完整日历

Question

I have full calendar and when getting the data for event I get error in this line

end: event.end.format() || event.start.format(),

saying

Uncaught TypeError: Cannot read property 'format' of undefined

According to this

a work around is

eventClick: function(event) {
    var start = event.start;
    var end = event.end || start;
}

but it didnt work for me

What is the best way to handle end date in full calendar

eventData = {
  id: id,
  sysid: sysid,
  title: title,
  start: event.start.format(),
  end: event.end.format() || event.start.format(),
  description: description,
  otherinformation: otherinformation,
  page: page,
  action: action

};

Answer 1

Problem with your implementation is it checks for truthy ofthe formatted value, it doesn't evaluate whether event.end is truthy . So when event.end evaluated to falsey the error is thrown.

You should check for event.end to be truthy , thus use

end: (event.end || event.start).format()

Or, As suggest by API Docs

var start = event.start;
var end = event.end || start;

eventData = {
  end: end.format(),
};
