columnHeaderText
Programmatically generates text that will be displayed on the calendar’s column headings.
function( date ) -> string
This function will will receive a date object that represents a single column’s date and must return a string to be displayed. The text will be escaped before being inserted into the DOM. You do not need to worry about escaping HTML entities.
Example:
var calendar = new Calendar(calendarEl, {
columnHeaderText: function(date) {
if (date.getDay() === 5) {
return 'Friday!';
} else {
return date.toString();
}
}
});
If you are simply stringifying a date with a formatting string, using columnHeaderFormat is more elegant.
If you need to generate HTML, use columnHeaderHtml instead.
