One more time, thanks very much for your answer.
Now, my code is very similar as the one you sent and the js timepicker is the older version. I may miss something, but it is still the same thing : I can enter any numerical input but no timepicker appears.
Of course I made un echo test to see if I really could execute js script and it worked.
I don't understand what I am doing wrong, but I think I'll give up.
<div id="question34" class="numeric mandatory">
<table class="question-wrapper">
<tr>
<td class="questiontext">
<span class="asterisk">* </span>
<span class="qnumcode"> </span>
Heure de départ :
<script src="/upload/surveys/33913/jquery-ui-timepicker-addon.js"></script><script>
$(document).ready(function(){
$(".numeric:eq(0) input.text").timepicker({
timeText: 'Time',
hourText: 'hour',
minuteText: 'minute',
closeText: 'Done'
});
$(".numeric:eq(0) input.text").attr('readonly', 'readonly');
$( "<style>"
+".ui-widget-header, .ui-datepicker-current { display:none; }"
+".ui-timepicker-div dl dt { height: 25px; margin-bottom: -25px; }"
+".ui-timepicker-div dl dd { margin: 0 10px 10px 65px; }"
+" }"
+"</style>").appendTo( "head" );
});
</script>
