On Update is a field action that triggers a script when a field value is modified. Note that this section is executed only if the field value has been successfully edited.
Go to https://creator.zoho.com/sampleapps/script-actions/#View:On_User_Input_View and edit any record. There is a hidden field that captures the new updated value in its field. Below code was written in the On Update section.
Updated_Value = Choose_any_option;
You may want to send email to the administrator when a field value is modified. In that case, you can write the send mail task in the On Update section of the field.
