Copy the data from first line while dynamically adding a new line in table

Question

Hi,
1. There is a table
2. An add button adds a new line to the table using 'AddInstance'
3. A record is entered in the first line
4. When the add button is clicked it adds a new line and along with it copies the data entered in the first line
My question is how to copy the data from the first line and show it in the new line added. This is required so that user can use most of the common values in the first line.
Thanks,
Nikhil

Answer 1

You can use the following Java Script in the Click event of the button.
// Get the number of rows in the table
var nrows = xfa.resolveNodes("page.table.DATA[*]").length;
// Add a new instance(row) to the table
page.table.addInstance.instanceManager(1);
xfa.form.recalculate(1);
// Copy the values from the first line to the newly created row
page.table.DATA\[ nrows \].field1.rawValue = page.table.DATA\[ 0 \].field1.rawValue;
..........field2
..........field3
