I would like to be able to save several input fields on a new page in a custom version of Customer Portal. 

The idea is that I have a checklist which always consists of different fields that are put into a table using foreach. 

I would now like the customer to be able to leave a comment in certain fields. I would then like to save this in the order rows from where the list of fields was created in the same row on a comment field. 

But the problem is that I have a different number of different fields that I want to save and I don't want the page to be reloaded when I save the fields. 

Ideally I would like to have a button next to the comment which then makes the transfer. 

How can I solve this without using the post method which reloads the page?
