How to monitor a form form has a value changed

as shown in the figure, I click on different form components to change the corresponding field properties on the right. Currently, you need to click Save, and then get the modified field attribute push to the data structure. According to the customer"s request, you need to modify the data in real time and save it to the corresponding object in the corresponding array in real time. How to monitor? Is there a better way to implement
than an input box listener? Can you monitor the value of this form form to modify it? Either the jquery or the js method is fine! I"m in a hurry! Thank you, gods!
