I am trying to have form options generate dynamically based on other answers. This can propagate to many fields within a large form. In the basic example below, there is an ad_form test_form with a select widget, call it subgroup_id, that I would like to populate dynamically based on another input, call that supergroup_id.
Relevant TCL:
set supergroup_list [list {"Select One" ""} {"A" "1"} {"B" "2"} {"C" "3"}]
set subgroup_list [list {"Select One" ""}]
ad_form \
-name test_form \
-form {
{supergroup_id:text(select)
{options $supergroup_list}
}
{subgroup_id:text(select)
{options $subgroup_list}
}
}
Relevant ADP:
<formtemplate id="test_form"></formtemplate>
<script type="text/javascript" <if @::__csp_nonce@ not nil> nonce= "@::__csp_nonce;literal@"</if>>
document.getElementById("supergroup_id").addEventListener("change", function(event) {
const select = document.getElementById("subgroup_id");
// Remove all options
select.innerHTML = "";
// Add initial "Select One" option
const option0 = document.createElement("option");
option0.text = "Select One";
option0.value = "";
select.appendChild(option0);
switch (this.value) {
case "1":
const option1 = document.createElement("option");
option1.text = "Ex 1";
option1.value = "7";
select.appendChild(option1);
const option2 = document.createElement("option");
option2.text = "Ex 2";
option2.value = "8";
select.appendChild(option2);
break;
case "2":
const option3 = document.createElement("option");
option3.text = "Ex 3";
option3.value = "7";
select.appendChild(option3);
const option4 = document.createElement("option");
option4.text = "Ex 4";
option4.value = "8";
select.appendChild(option4);
break;
case "3":
const option5 = document.createElement("option");
option5.text = "Ex 5";
option5.value = "7";
select.appendChild(option5);
const option6 = document.createElement("option");
option6.text = "Ex 6";
option6.value = "8";
select.appendChild(option6);
break;
}
});
</script>
The example works with OpenACS 5.9.1, but with OpenACS 5.10.1b1 the form is returned with "Invalid Choice" next to the subgroup_id label and the form doesn't process.
Are there any suggestions on how to allow this dynamic form creation in 5.10.1 without a large amount of restructuring? Any help or guidance would be greatly appreciated.
