Recipe #9.3: JavaScript Forms
Another very common use for JavaScript is to validate forms. Usually these
forms can be treated as normal forms. However, sometimes these forms will make
use of an
<input type="button">
tag to submit, rather than the usual
<input type="submit">
. If an
<input>
tag makes use of the
button
type,
rather than
submit
, then JavaScript must be used to submit the form. This recipe will show
how to process such a form. You can see the form that this recipe will process at the following
