The alert() function is synchronous and you can't verify what was clicked (it does not return anything), so the code below the call will be executed after it is closed (ok or close button). The alert is not used to gain user input. It is an alert, a message to the user. If you need to check what the user want, you should use confirm(). Note that the function name tells its purpose like alert.

Something like:

// if the ok button is clicked, result will be true (boolean)
var result = confirm( "Do you want to do this?" );

if ( result ) {
    // the user clicked ok
} else {
    // the user clicked cancel or closed the confirm dialog.
}
