javascript - How to get original value if want to reset changes in reactjs by using controlled components in reactjs? -


i having issue while prefilling values , changing in reactjs.

i have table , consist of lots of data,also in table have option of update. so, on click of update open model , prefill values. can't use defaultvalue because when modal rendered first time user, fields in model set user if again open model user,since defaultvalue set on initial render , model got rendered once. have use value. if use value, have call onchange function update state able update values in fields.

the problem in case after doing bit change want cancel , revert changes since state updated, don't have initial value of field. how revert changes on click of cancel if have option of cancel.

i think problem straight forward. if didn't problem please comment provide code understand this.

any appreciated. :)
