I want to create a new db use openDatabase and I get SecurityError like this:

so if any ideas,

Can I pause my web app running  when creating db ,and go on when user choose yes or no?

and how can I know user choose which one?

or can I settings “yes” as default (means I have the privilege  to create the db without notify user)?
