Question

I have a textbox, I need to check if the textbox is empty and set a variable accordingly to true or false.

my code at the moment print the value of the textbox.

var isDateTimEndEmpty = dateTimeEnd.val() == null ? true : false;

what am I doing wrong here?

Answer 1

Here is the correct way:

var isDateTimEndEmpty = !$.trim(dateTimeEnd.val()).length;

Good practice is to use $.trim which makes the code to ignore spaces in the input field. So if the length of trimmed value is 0 then the value is empty.
