Hi, everyone This is a suitelet with html , now all this is working in GET, now I want to submit values to the sales order corresponding to the "select" button. I have created custom fields to store. Select button is a link, (a href=""Select/a). How can send an object to post of this suitelet on a button(Select) here.

keeping in mind that there are frameworks designed to solve this problem

reference please

but you add an on click event listener to your link to send an xhr post to the suitelet
