Populate field1 in table, based on dropdown value of a field2 in same row

Question

Hi Experts,
I have created an offline interactive Adobe form and need help with java-script on events. I will describe my scenario below -
I have written an SE38 report program which will generate the PDF. To pre-populate fields in the PDF, I have a structure Default_Values which has a few internal tables. One of the internal tables Employees has 2 fields Emp_Code and Emp_Name. I have written code to obtain a list of employees and populate this internal table Empoyees. I call the Adobe form and along with other parameters, pass this structure Default_Values. Thus all the default values along with the internal table Employees pre-populated with the Employee Code and Employee Names have been passed to the Context.
In the Adobe form I have a table with 10 lines with Employee details (6 columns, 2 of which are Emp_Code and Emp_Name)
In this table control, the column Employee Name is a drop down list. For this column, under List Items, I have created a binding to the internal table Employees with default values. This binding Items looks like this - $record.DEFAULT_VALUES.EMPLOYEES.DATA[*] with Item Text and Item Value having the value EMP_NAME.
When I test the form, I can see all the Employee Names in the drop down list in the column Employee Name of the table control.
My requirement is that when a user selects an Employee Name from the drop-down list, the field Emp_Code for that row in the table control should be automatically populated with the corresponding value of Emp_Code  depending on the Emp_Name which the user has selected.
I am new to Java-scripts and Adobe forms. I have searched this and other forums, however I couldn't find the right code which I can place in either the Change or Exit event of the drop-down to accomplish this.
Can someone please provide me with sample code to achieve this.
Any help will be greatly appreciated.
Thanks in advance.

Hi Neha,
I would prefer not to use FormCalc for this requirement.
Array Processing shall be done in Java Scripting and you simply cannot have two different scripting language elements in the same scripting block.
First create a table type parameter in the interface or GT_* type in Global variable and pass all the necessary entries of dropdown to the table type parameter. Once included in the context it shall be available in your data view of the form.
To access any repeating instance node of the form in the data view, use te following script -
var theFields = xfa.resolveNodes(
                  "xfa.datasets.data.data.CUSTOMERS.DATA[*].NAME");
assuming that you have a table named CUSTOMERS in the Data View.
For more details on XFA Data Model refer to

Hope these inputs help.
