Answer 1

Get rid of the inline onclick() event in your HTML, and let your JavaScript handle the click:

$('#send').click(function(e){
    e.preventDefault();
    sendContact();
});

preventDefault() stops the click event from acting normally, so your form data is submitted without reloading the page.
