javascript - 第二只动画眼睛的重复代码

我开始学习JavaScript，并且尝试扩展Codepen上的代码。

现在，我想在这里复制这只眼睛，以便两只眼睛跟随我的光标。我开始使用不同的变量以及关键帧动画来复制整个功能，但是我想这不是正确的方法，而且也无法正常工作。

http://codepen.io/GottZ/pen/XbxBXw

var eye;
var n_eye = document.querySelector(".eye");
var n_iris = n_eye.querySelector(".iris");
var size = n_eye.clientWidth;

(window.onresize = function () {
    eye = {
        x: n_eye.offsetLeft + size / 2,
        y: n_eye.offsetTop + size / 2
    };
})();

window.onmouseout = window.onmouseleave = function () {
    n_iris.setAttribute("class", "iris anim");
};

window.ontouchend = function (e) {
    if (e.touches.length == 0) window.onmouseout();
}

window.onmousemove = function (e) {
    n_iris.setAttribute("class", "iris");
    var m = {
        x: e.clientX - eye.x,
        y: e.clientY - eye.y
    };
    m.rx = 0 - m.y;
    m.ry = m.x;
    ["rx", "ry"].forEach(function (r) {
        m[r] *= 0.1;
        m[r] = Math.max(-60, m[r]);
        m[r] = Math.min(60, m[r]);
    });
    n_iris.style.transform = "rotateX("+m.rx+"deg) rotateY("+m.ry+"deg) translateZ(68px) scale(0.6)";
};

window.ontouchmove = window.ontouchstart = function (e) {
    var touch = e.touches[0];
    window.onmousemove(touch);
};

有人可以帮我吗？我将对正确而干净的方法应该如何进行感兴趣...

谢谢!

最佳答案

我已经更改了您的CSS jqquery和html。看一看。根据需要更改眼睛的位置。

  $(function () {

            var eyeL;
            var n_eyeL = document.querySelector(".eyeL");
            var n_irisL = n_eyeL.querySelector(".irisL");
            var sizeL = n_eyeL.clientWidth;

            var eyeR;
            var n_eyeR = document.querySelector(".eyeR");
            var n_irisR = n_eyeR.querySelector(".irisR");

            var sizeR = n_eyeR.clientWidth;

            (window.onresize = function () {
                eyeL = {
                    x: n_eyeL.offsetLeft + sizeL / 2,
                    y: n_eyeL.offsetTop + sizeL / 2
                };
                eyeR = {
                    x: n_eyeR.offsetLeft + sizeR / 2,
                    y: n_eyeR.offsetTop + sizeR / 2
                };
            })();

            window.onmouseout = window.onmouseleave = function () {
                n_irisL.setAttribute("class", "irisL anim");
                n_irisR.setAttribute("class", "irisR anim");
            };

            window.ontouchend = function (e) {
                if (e.touches.length == 0) window.onmouseout();
            }

            window.onmousemove = function (e) {
                n_irisL.setAttribute("class", "irisL");
                n_irisR.setAttribute("class", "irisR");
                var m = {
                    x: e.clientX - eyeL.x,
                    y: e.clientY - eyeL.y
                };
                m.rx = 0 - m.y;
                m.ry = m.x;
                ["rx", "ry"].forEach(function (r) {
                    m[r] *= 0.1;
                    m[r] = Math.max(-60, m[r]);
                    m[r] = Math.min(60, m[r]);
                });
                n_irisL.style.transform = "rotateX(" + m.rx + "deg) rotateY(" + m.ry + "deg) translateZ(68px) scale(0.6)";


                var m = {
                    x: e.clientX - eyeR.x,
                    y: e.clientY - eyeR.y
                };
                m.rx = 0 - m.y;
                m.ry = m.x;
                ["rx", "ry"].forEach(function (r) {
                    m[r] *= 0.1;
                    m[r] = Math.max(-60, m[r]);
                    m[r] = Math.min(60, m[r]);
                });
                n_irisR.style.transform = "rotateX(" + m.rx + "deg) rotateY(" + m.ry + "deg) translateZ(68px) scale(0.6)";



            };

            window.ontouchmove = window.ontouchstart = function (e) {
                var touch = e.touches[0];
                window.onmousemove(touch);
