By adding this snippet of code to the directions part of the question, you can hide a field and then show it upon the user selecting the Yes option. You will need to adjust with the IDs associated with the specific question.
$("#s-2677_3474").hide();
$("#content_field_2669_3466 input").on("change", function() {
if ($("#content_field_2669_3466 input:checked").val() == "Yes") {
$("#s-2677_3474").show();
} else {
$("#s-2677_3474").hide();
}
});
Another example shows you how to target the specific survey_no no matter what page it's on.
if (curObj.survey_no == 1234) {
$("#s-4655_6360").hide();
$("#s-4286_6341").hide(); $("#s-3612_6871").on("change", function() {
if ($("input:checked", this).val() == 'Yes') {
$("#s-4655_6360").show();
$("#s-4286_6341").show();
} else {
$("#s-4655_6360").hide();
$("#s-4286_6341").hide();
}
})
}
