in this code I want to cancel on Sunday

i try in

this.week = this.opt.date.getDay();


    if(this.week == 4)
        d.addClass('calDisable');

Answer 1

the getDay() method is zero-indexed, and Sunday is the first day of the week, so you need to run whatever code you need when this.week === 0

• 0 = Sunday
• 1 = Monday
• 2 = Tuesday
• 3 = Wednesday
• 4 = Thursday
• 5 = Friday
• 6 = Saturday

Answer 2

this.week = this.opt.date.getDay(); if(this.week === 0) d.addClass('calDisable');

This should work. Not sure why are you comparing to 4 since 4 represents Thursday.

The value returned by the Javascript getDay() method is an integer corresponding to the day of the week. It will be 0 for Sunday, 1 for Monday, ..... , 5 for Friday and 6 for Saturday.
