It still doesn't validate when the field is empty. Yes, I removed "
required: true, " in
$("#myform").validate({
rules: {
field: {
required: true,
email: true
}
}
});
The code is exactly the same just without the required: true, line as
belows.
And if I modified the <input id="field" name="field" /> to <input
class="left" id="field" name="field" onblur=alert($("#field").valid
()) /> It alerts 0 when it's empty, 0 when it's invalid email, and 1
when it's valid email address. I'm expecting 1 when field is empty.
