Java script (last_day)

[Sheikha]

hi:

im building a web based vb.net application. i want to write a javascript in teh html side. basically the user enters a date. it has to be end of the month. for example 31-jan-2005 and not 5-jan-2005. iof teh user enters 5-jan-2005, he should get an alert saying to enter teh date of end of the month.

in sql its like last_day(date). but how do i do it in javascript?

thanks

Only allow the user to enter the month and year.

Sheikha,

Did DeadEye's suggestion help you?

Is so thats great.

If not then can you explain how your interface is designed and why DeadEye's suggestion did not help? Thanks.
