How can I update a text field that is hidden triggered by a rule?

Hi NeoInJS,

In your details page, let's say you have the following fields:

• Textbox1
  • Set as form element: Hidden
• Virtual1
  • Set as form element: Checkbox
• Virtual2 
  • Go to Advanced > External Associations and Defaults > Set On load to receive value or parameter: Data Source Fields | Textbox1

Rules

|---------------------|----------------------|
| CRITERIA            | ACTIONS              |
|---------------------|----------------------|
| Virtual1 is checked | Make Virtual2 hidden |
|---------------------|----------------------|

Create a Header/Footer and insert the code below in the Footer

<script>

// This will copy the value you enter in Virtual2 to Textbox1
document.getElementById('cbParamVirtual2').onkeyup= function(){
 var x = document.getElementById('cbParamVirtual2').value;
 document.getElementById('EditRecordTextbox1').value = x;
};

</script>
