I've tried implementing your solution as suggested, but unfortunately, it's still not functioning. Do you have any other ideas? Thank you.
code
open_links() {
var options = document.querySelectorAll('#dwl option');
for( var i = 0 ; i < options.length ; i++ )
window.open(options[i].value, '_blank');
}
**HTML**
<li id="li_8">
<label class="description" name="Download">Download a HTML sample</label>
<div>
<select id="dwl">
<option value="http://www.bbc.co.uk/">Sample 1</option>
<option value="http://www.bbc.co.uk/">Sample 2</option>
<option value="http://www.bbc.co.uk/">Sample 3</option>
<option value="http://www.bbc.co.uk/">Sample 4</option>
<option value="http://www.bbc.co.uk/">Sample 5</option>
</select>
<input type="button" onclick="open_links()" value="Download" />
