Onclick Confirm Not working

Question

Hello I have this line of code.

onClick=\"confirm(\'Are you sure you want to update the database
   to the latest version?\')\">
Updat         


        

Answer 1

You must use return confirm(...) instead of just confirm(...) for it to work.

Answer 2

Confirm function actually returns a boolean. It's true if the user clicks ok, and false if cancel is clicked.
So you need to save the return value of confirm function in a variable, and then check that variable to perform desired operations.
