introduction and a question…

Hi Everyone,

Just found the site. Right now, I’m a serious web newbie. But once I get
more up to speed on things, I’m looking forward to contibuting as much as
possible. I’ve been developing applications in Lotus Notes for the last 7
years, and have recently started developing for the web. As such, I’ve been
using JavaScript a bit, but I’m sure I’m gonna have some questions.

Like this one… ?

I have a form with separate fields for month day and year. If the user
enters 4 in the month or day field, I need them to autofill with a zero
(ie. 04). What’s the easiest/best way to do this in JS?

Thanks in advance…

Steve

@felgallApr 26.2006 — Assuming your form is named "myform" and the input field for the day is named "day" then calling the following code would insert the leading zero if required.

var day = parseInt(myform.day.value);
myform.day.value = (day < 10) ? '0'+day : day;

@stevemtnoauthorApr 27.2006 — Hi Stephen,

Well, the users like the autofill so much, they came up with an couple more things for their 'want list':

  • 1. Ensure that the month entered is valid (01 - 12)

  • 2. Ensure that the day entered is valid for the month


    • Is there an easy way to do this?

    Thanks!
