Get inputing data in Form Script

I have Custom Script for Form like this:

frappe.ui.form.on('Key Results', {
	refresh(frm) {
		// your code here
		frm.doc.current_progress = flt(frm.doc.current) / flt( * 100;

But I found that frm.doc.current value is the value stored in Database, not in submitting form. For example:

  • Old current value is 1, target is 2. Update new current value to 0, progress is 50 (because it use 1/2 instead of 0/2)

Is there a way to get data in submitting form?
