Js To Clear Conditional Child Input Fields

[costar]

i have a field on a submission data page which if checked will display other other fields to be checked which have been hidden by a rule, but if I un-check the parent field the children fields disappear but remain checked. Can I use JS to clear the children cells if the parent is un-checked?

many thanks

Hello costar,

 

You can use following code in the footer field: 

<SCRIPT type="text/javascript">

function f_a(v_id){ return document.getElementById(v_id); }
function f_b(v_id){ return f_a('InsertRecordcheckbox' + v_id);}
function f_findParentTR(v_node){
 var v_parentNode = v_node;
 if(!v_node) return null;
 while(v_parentNode && String(v_parentNode.nodeName).toUpperCase() != 'TR')
  v_parentNode = v_parentNode.parentNode;

 return v_parentNode;
}
function CheckboxesCheck() {
 if (f_b("1").checked){
  f_b("2").checked=true;
  f_b("3").checked=true;
 } else {
    if(!f_b("2").checked){
    f_findParentTR(f_b("2")).style.display='none';
    }
    if(!f_b("3").checked){
    f_findParentTR(f_b("3")).style.display='none';
    }
 }
}
f_b("1").onchange=CheckboxesCheck;
</script>

Note: The code works for three fields with 'Yes/No' DataTypes. 

 

Hope it helps.
