I would use jQuery.ajax to load the decisiontree div content dynamically when the user clicks the submit button. You would need to put your decisiontree div content code in a separate file(decisiontree.html) and give your submit button an id.
<script>
$(function()
{
$("input#submit").live('click', function()
{
loadApplet();
return false;
});
function loadApplet()
{
jQuery.ajax({
type: 'GET',
url: 'decisiontree.html,
success: function(data) {
$('#decisiontree').html(data);
}
});
};
});
</script>
This is a great resource for jQuery.ajax: http://api.jquery.com/jQuery.ajax/
