Hi Jörn and others jquery forum readers,
So, is there anything wrong with the script? It still doesn't work
when email field is empty; fine with both validating the field when
there is input. onblur=alert($("#field").valid()) gives me 0 when
empty.
$(document).ready(function(){
$("#myform").validate({
rules: {
field: {
email: true
}
}
});
});
<form id="myform">
<label for="field">Required, email: </label>
<input class="left" id="field" name="field" onblur=alert($
("#field").valid()) />
<br/>
<input type="submit" value="Validate!" />
</form>
