Date in javascript (not show 31 in february ...)

[Daft]

Hi

I must do a form where I ask for the birthday, I do 3 <select> and I want that when I choose february, the 31° are not available ? How can I do that ??

Please Help

set an onchange event on the month select box, and make it call a javascript function that updates (or only checks for the value) for the day

Yeah Iza that i know but how can I in javascript 'hide' some number in the day-select ?

i would remove the values > 29 if the month is february, add them instead. There might be a smarter solution but i don't see :-(

removing an option
the_name_of_your_lisbox.options.remove(the_index_of_the_item_you_wish_to_remove);

adding an option
var oOption = document.createElement(&quot;OPTION&quot;
oOption.text=the_text_of_the_item_you_want_to_add;
oOption.value=the_value(index)_of_the_item_you_want_to_add;
the_name_of_your_lisbox.options.add(oOption)

You could have an array which holds the number of days for each month, where the index will correspond to the month:

daysArray[0]= days in January etc...

onChange in the month select box add some script which just takes the selected index from the month, and applies it to your array, returning the number of days.You can for loop it put all the values in for you.
