Answer 1

Example of that behavior with jquery.
You need to match the select id and also insert a span tag inside the button with a matching class

Live example:

From gravityforms site:

there is an easy way to add custom Javascript to your Gravity Forms that only loads when the form is rendered. Just copy-and-paste your desired snippet into the robust editor on your Form Settings and you're golden.

<div>
    <select id="picker">
        <option value="5">5 items</option>
        <option value="4">4 items</option>
        <option value="3">3 items</option>
        <option value="2">2 items</option>
        <option value="1">1 items</option>
    </select>
</div>
<div>
    <button>user picked <span class="pickedAmount">1</span> items</button>
</div>


<!-- copy this into gravity form -->
<script>
// picker - is the ID of the select
// pickedAmount - is the CLASS of the span 
jQuery(function($){
 
    $('#picker').on('change', function() {
        $('.pickedAmount').text($(this).val());
    })

});
</script>
<!-- copy this into gravity form -->

Your JavaScript solution is :

<select onchange="my_fun(this)">
    <option>item one(1)</option>
    <option>item two(2)</option>
    <option>item three(3)</option>
</select>

<script>
    function my_fun(obj){
        alert(obj.options[obj.selectedIndex].text);
    }
</script>
