Hi Joffm,

Yes, I agree with you. But I am working on a complex questionnaire including many questions of respondents' history. For example, in this case, the original question is asking about people's illness history. The table will contain "illness" "When were you diagnosed with this illness?" "Have you recovered from this illness?" "If yes, when did you recover from this illness?" "Relapse or not?" The questions are continuous and we don't know how many experiences the respondent has. So I think it's better to achieve it in an array. If Limesurvey cannot do this, I will choose your solution. Thank you!

Hi,

Good news! I think I have solved this problem with the following code:

<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$('input[ name="{SGQ}SQ001_SQ002"]').change(function() {
$('input[ name="{SGQ}SQ001_SQ003"]').prop('disabled', true);
$('input[name="{SGQ}SQ001_SQ003"]').val("");
if ($('input[ name="{SGQ}SQ001_SQ002"]').val()=="3") {
$('input[ name="{SGQ}SQ001_SQ003"]').prop('disabled', false);
$('input[name="{SGQ}SQ001_SQ003"]').val("");
}
});

});

</script>
