我想使用 konami 代码来实现它，我已经在我的网站上成功使用了它。我只是无法让它与 skifree 一起工作。 为了快速引用，这里是 konami 代码:

var kkeys = [], konami = "38,38,40,40,37,39,37,39,66,65";
$(document).keydown(function(e) {
 kkeys.push( e.keyCode );
if ( kkeys.toString().indexOf( konami ) >= 0 ){
$(document).unbind('keydown',arguments.callee);
// Launch easter egg here
  }
});

这是从该站点提取的 skifree 代码:http://timelessname.com/canvas/skifree/

    var left;
    var right;
    var faster = false;

    var step = 0;
    var obst = new Array();

    var locX = 430;
    var locY = 100;

    var running = true;

    var guy = new Image();
    var guyLeft = new Image();
    var guyRight = new Image();
    var crash = new Image();
    var rock = new Image();
    var tree = new Image();
    var bush = new Image();
    guy.src = "http://timelessname.com/canvas/skifree/guy_down.png";
    guyLeft.src = "http://timelessname.com/canvas/skifree/guy_left.png";
    guyRight.src = "http://timelessname.com/canvas/skifree/guy_right.png";
    crash.src = "http://timelessname.com/canvas/skifree/crash.png";
    rock.src = "http://timelessname.com/canvas/skifree/rock.png";
    tree.src = "http://timelessname.com/canvas/skifree/tree.png";

    $(window).keydown(function(e){
        if(e.keyCode == 37){
            left = true;
        }
        else if(e.keyCode == 39){
            right = true;
        }

            faster = true;
        }
    });

            right = false;

            faster = false;
        }

最佳答案

不确定，但您复制的代码看起来不对；看这里:

    if(left){
        if(locX > -320){
            locX--;
        }
    }
    if(right){
        if(locX < 640+320){
            locX++;
        }
    }

你是从html复制过来的吗？ > & <不应转义字符 :)

同时记得更新你的图片路径 :D

我让这个在这个页面上工作。刚刚添加了 <canvas/>元素，将 ski javascript 包装在一个名为 setupSki 的函数中(由 konami 函数调用)并替换了

setTimeout("runSki();"

与

setTimeout(runSki

关于javascript - 无法将 skifree 添加为复活节彩蛋，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11759612/
