Question

"An error occurred stating that currDateEnd.setHours is not a valid function

I am attempting to transform my date into ISO format and adjust the hours to 23. Below is my code:

var currDateEnd = $('#calendar').fullCalendar('getView').start;
console.log(currDateEnd);
currDateEnd.toDate().toISOString();
console.log(currDateEnd);
currDateEnd.setHours(23);

OUTPUT

Mon Oct 19 2015 02:00:00 GMT+0200 (ora legale Europa occidentale)

Mon Oct 19 2015 02:00:00 GMT+0200 (ora legale Europa occidentale)

However, I encounter an error on the last line:

currDateEnd.setHours is not a function

What could be causing this issue? Is there a solution to rectify it?

UPDATE

Upon running the following code:

var currDateEnd = $('#calendar').fullCalendar('getView').start;
console.log("currDateEnd iso => ", currDateEnd.toDate().toISOString());

The output generated is as follows:

currDateEnd iso => 2015-10-19T00:00:00.000Z

Answer 1

Answer №1

currDateEnd.setHours(23);

should be

currDateEnd.toDate().setHours(23);

It is important to note that .setHours() is a method that can only be called on a Date object. Since you are working with a Moment object named currDateEnd, you need to convert it to a Date object before using the method.

Answer 2

currDateEnd.setHours(23);

should be

currDateEnd.toDate().setHours(23);

It is important to note that .setHours() is a method that can only be called on a Date object. Since you are working with a Moment object named currDateEnd, you need to convert it to a Date object before using the method.

Answer №2

The reason for this discrepancy lies in the fact that setHours operates on Date instances, while currDateEnd is an instance of moment. To resolve this issue, you can utilize the hour method from moment js and then convert it to an ISO string.

currDateEnd.hour(23).toISOString()
