I would like to create a JavaScript function similar to confirm() that shows a dialog (a div with a question and 2 buttons) and returns true if the
Rather than waiting for the user's input and then returning from the function, it is more common in JavaScript to provide a callback function that will be called when the action you're waiting for is complete. For example:
myCustomConfirm("Are you sure?", function (confirmed) {
if (confirmed) {
// Whatever you need to do if they clicked confirm
} else {
// Whatever you need to do if they clicked cancel
}
});
This could be implemented along the lines of:
function myCustomConfirm(message, callback) {
var confirmButton, cancelButton;
// Create user interface, display message, etc.
confirmButton.onclick = function() { callback(true); };
cancelButton.onclick = function() { callback(false); };
}
