confirm Examples

The general syntax for this method is:

let answer = window.confirm("Message to user");

Displays a dialog box with a message and returns true if user clicks “ok” and false if user clicks “cancel”. The browser waits until the user clicks “ok” or “cancel”.

Example

let response = window.confirm("Would you like to play a game?");
// Code does NOT continue until user responds to confirm window
if (response) {
    console.log("Let's play a board game");
} else {
    console.log("Oh well, let's code instead");
}

Note

Remember that methods defined on window can be used without referencing the window variable.

Example

<!DOCTYPE html>
<html>
    <head>
    <title>DOM Examples</title>
    </head>
    <body>
    <h1>Window Confirm Example</h1>
    <script>
            let response = confirm("Are you excited?");
            if (response) {
                console.log("Yay! Me too!");
            } else {
                console.log("Oh no! I hope tomorrow is a better day!");
            }
    </script>
    </body>
</html>

Console Output (If “cancel” clicked)

Oh no! I hope tomorrow is a better day!
