I am allowing a user to selected a date to schedule an event and it
seems like the best way to do this is with drop down menus for Year,
month, date. However I would like to make it so when you choose a year
and a month the appropriate days for that month show (i.e. 28 days if
you chose February 2006). I can easily do this with a loop if I can
find out what month the user has selected, but I can't seem to find a
way to get that value. Is there a simple javascript solution to this
problem?
<select name="myMonthList"
onchange="setBestDay(this.form, this.selectedIndex)">
<option value="0">January</option>
...
</select>
where in the <head> section you have:
<script type="text/javascript">
function setBestDay(f,m) {
// m corresponds to the selected month
// 0 - January, 11 - December
// do your calculations
// then:
f.myDayList.selectedIndex = myCalculatedIndex;
}
</script>
There is much to be said for understanding a question before attempting
to give an answer - you should try it sometime.
