if (email.test(mail))
{
    window.location.href = 'URL to redirect';
}
else
{
    alert("Enter a valid email");

}

or

 if (email.test(mail.value))
{
      window.location = 'Default.aspx';
}
else
{
     alert("Enter a valid email");
     this.focus();
}

Solution 4

Add "return false" when the validation passes, so as to cancel the button1_click event.

window.location="Default3.aspx";
return false;
