How check if email element is valid?

Question

I use LiveValidation plugin (http://livevalidation.com). I need validate one input and if it is ok, make same ajax. Instead submit button I have img and I would like to process it by onClick action. Everything works validation works live, but when I click on image I need to check if is email fill and valid. Is some method like isValid or how can I do it and avoid to process ajax always after click?

<input id="email" type="text" name="email" />
<img id="sendToEmail" src="send.png" />

<script type="text/javascript">
var email = new LiveValidation('email', { validMessage: ' ', wait: 500 } );
email.add( Validate.Presence, { failureMessage: "Is required" } );
email.add( Validate.Email, { failureMessage: "Must by email" } );

$('#sendToEmail').click(function() {
  if (email.isvalid) {
    //ajax calling
  }
})
</script>

This is right solution

if (email.validate()) {
  // some process if is validated
}

You can use:

 $(function(){
    $('#sendToEmail').click(function(){
        if ( !email.validationFailed ){
           //ajax calling
        }
    });
});
