<form onsubmit='return false'>

No, the only valid test of an emailaddress
is the reception thereof by the intended "to"-person.
Don't know what you mean by "without re-checking"!
A partial test is easy like:
<form onsubmit='return
/^[^@]+@[^@]{3,}$/.test(this.form.myEmailField.value'>
but can be made nonsensically more complex.
