It is a example of add button functionality use it 

In a visualforce page with two different components a & b, i want to create an add button which adds fields from component A and add it to the fields on component B while creating a record on component B.

both these components have same field name (ADD)

Component a(object 1)      Component b (object 2)
FIELD 1                    FIELD 1
FIELD 2                    FIELD 2
FIELD 3                    FIELD 3 
FIELD 4                    FIELD 4
START DATE/TIME            START DATE/TIME           
END DATE/TIME              END DATE/TIME
the add button has to pickup the field values from component A and add it to Component b.
