Hi Everyone,
I need to pop up a prompt when user click on update button, if the required fields are left behind. Can anyone please guide me how to achieve this.

For this the most common and most supported technique is to use field-level and/or form-level validation messages. You could conditionally enable a button confirmation message when some on-form conditions are not met, however this can be tricky to setup and maintain and ends up being a bit of a workaround approach only.
