The JavaScript is very simple and looks like this:
<script type="text/javascript">function buttonClick(){ var elem = document.getElementById('selection'); elem.innerHTML = document.getElementById('year').value;} </script>
You can see that we grab the element with the ID of selection and write the value of the year to it. You will, I am sure, wish to produce something a little more sophisticated than this! Now we have the basics, the second example is a bit more complex. In this example, we will be passing messages directly between server (R) and client (JavaScript).
