How to update the multiple objects of array on single click?

[Deepak8717]

Hi i’m making backtesting stimulator and

1. I have a form to add leg
2. list of legs (coming from an array of objects)

I have onchange event on each field and each leg can be edited. However, I don’t want to update the individual object of arrayList. I have to update every individual changes on single update button

i am unable to do is after i edit those legs i want to be able to update them all in on click of final update button and not have update for each leg form.

here is the code if you want

I apologize i did not understand your advice. i need the user to be able to edit each leg that’s why I have onchange event on each leg. However onchange doesn’t update the array and I am unable to figureout how to update all the changed objects with in array all at once.
I made a minimal representation of what I am talking about. may be it should be easy to understand.
