Question

Is there any fnction in the JQuery datepicker custom ui where I can get the total number of days by passing on the month name and year?

Answer 1

Just use regular Javascript. No need for jQuery. I’m not sure what the date picker returns but if you can get the year like ‘2012’ and the month like ‘2’:

var year = 2012;
var month = 2;
var days = Math.round(((new Date(year, month))-(new Date(year, month-1)))/86400000);

Since 2012 is a leap year, and 2 is February the above code days becomes 29.
