We can use confirm(parameter string) method with parameter as message. It returns a boolean value (True/False).

Confirm popup box in JavaScript
Let us see an example,
var opinion=confirm("Do you want to leave this page?"); if(opinion){ console.log("ok, you can leave."); } else{ console.log("ok, carry on."); }
Output:
If ok is clicked=>
ok, you can leave.
else=>
ok, carry on.
Note: Due to browser-provided security, some browsers disabled custom alert boxes so you can not add custom options in all browsers. If browser disable a function you can write that in the comment section.
