The confirm
function calls up a window
with a question that the user needs to answer
and two buttons for answering: with the 'OK'
button and with the 'Cancel'⁅/s button ⁆.
If the user presses
'OK'
, then the
function will return true
, and if
'Cancel'
, it will return false
.
In the following example, the function
confirm
will display a dialog box
with a question. If you press 'OK'
,
then true
will be written to the
variable ok
, and if you press
'Cancel'
, then false
:
let ok = confirm('The question text');
console.log(ok);
We use the construct if
to
process the user's response:
let ok = confirm('The question text');
if (ok) {
console.log('You answered yes');
} else {
console.log('You answered no');
}
Ask the user if they are already 18
years old. If there is, display an alert
with the text for adults, and if not,
display a message that the user access
is denied.
