Answer 1

You can do this with pure Javascipt. Here is a rough pseudo-code to start you off inside IIFE:

<form method="GET" action="/site">
    <input type="text" name="page" id="yourInput" />
</form>

<script>
(function() {
    var el = document.getElementById('yourInput'); //Get your input by ID
    el.onblur = function() { // when focus lost...
        this.form.submit(); // submit the form
    }
})();
</script>
