jQuery Konami代码监听器

Posted 2021-02-26

This is the code to add to a website to listen for the Konami Code (as implemented on jQuery.com"

if ( window.addEventListener ) {
    var kkeys = [], konami = "38,38,40,40,37,39,37,39,66,65";
    window.addEventListener("keydown", function(e){
        kkeys.push( e.keyCode );
        if ( kkeys.toString().indexOf( konami ) >= 0 )
            // User entered Konami Code, do something cool!!!
    }, true);
}
