Validations errors on a alert

[eluser]Tomer Simis[/eluser]
There is some way that a javascript alert appears with the validation errors?

I'have tried this:

Code:

$errors = validation_errors();
    if(!empty($errors)){
        echo '[removed] alert("'.$errors.'");[removed]';
    }

but it doesnt shows the alert.

Code:

<?php
// if errors
if ($this->form_validation->run() == FALSE)
{
     // display errors
     echo validation_errors();
     // in your case, you would echo javascript code for alert
}
?>
