Get value from option value table in UCI file

For Developers

How to get the value from an option object in a section of a UCI File to write it in another file using CBI models.

With the following script it´s already possible to read the option, but it writes the names of the fields and I haven´t been able to get the values because they seem to be in a table to which I can not found how to access.

Script:

mfs = fs:option(DynamicList, "src_mac", translate("MACs con Internet"))
mfs.datatype = "macaddr"

btn = s:option(Button, "_btn", translate("ClickM2RunDScript"))                                                                                                                                  
                                                                                                                                                                                                  
function btn.write()

Script prueba.sh

#!/bin/ash
