One possible solution is to add a class to every option
<select name="export_type" id="export_type">
<option class="export_option" value="pdf">PDF</option>
<option class="export_option" value="xlsx">Excel</option>
<option class="export_option" value="docx">DocX</option>
</select>
and then use the click handler for this class
$(document).ready(function () {
$(".export_option").click(function (e) {
//alert('click');
});
});
UPDATE: it looks like the code works in FF, IE and Opera but not in Chrome. Looking at the specs http://www.w3.org/TR/html401/interact/forms.html#h-17.6 I would say it's a bug in Chrome.
