When creating a dropdown box / menu and using the .change() event to bind a function to submit the form, in IE it triggers the function when clicking the select box.

When the page first loads, it works fine for the first time, then it fails for subsequent attempts - possibly because a selected="selected" has been added to one of the options by then (using server-side scripting). Tested in IE 7 & 8.

<script>

$(function() {

$('#industry-form input[type=submit]').remove();

$('#industry-form select').change(function() {$('#industry-form').submit()});

});

</script>

<p>Please select the sector you are interested in from the drop-down box below:</p>

<form id="industry-form" action="index.php" method="get">

<select name="sector">

<option value="0">[Select Industry]</option>

<option value="1">Aerospace</option>

<option value="2">Automotive & Engineering</option>

<option value="3">Chemicals & Plastics</option>

<option value="4">Defence</option>

<option value="5">Food & Drink</option>

<option value="6">General Manufacturing</option>

<option selected="selected" value="7">Healthcare</option>

<option value="8">Paper & Packaging</option>

<option value="9">Pharmaceuticals & Medical Products</option>

</select>

<input type="hidden" name="ar" value="144" />

<input type="submit" name="submit" value="Go >" />

</form>
