I want to create a drop down menu of month:, day:, and year. The difficulty with this one is that i dont know whether to make this a dynamic menu list - after all - the number of days within the day selection list depends on the month entered and also the year (in the case of a leap year)
So, can any one suggest me with this or can give a sample code..
Thanx
hi check out the code below... you will get drop down box with current month and year and the days for the particular month.
I have used 2 functions in the code .One for checking the leap year and other for populating the drop down box on body load.
Read the functions in the code and write a new function if you want to change day if users changes month or year.
And move this post to javascript forum
