大家好,今天给大家分享鼠标点击屏幕后如何出现小爱心的特效代码


JS代码如下:

<script>
        //鼠标点击出现爱心特效
        (function(window, document, undefined) {
            var hearts = [];
            window.requestAnimationFrame = (function() {
                return window.requestAnimationFrame ||
                    window.webkitRequestAnimationFrame ||
                    window.mozRequestAnimationFrame ||
                    window.oRequestAnimationFrame ||
                    window.msRequestAnimationFrame ||
                    function(callback) {
                        setTimeout(callback, 1000 / 60);
                    }
            })();
            init();

            function init() {
                css(".heart{width: 10px;height: 10px;position: fixed;background: #f00;transform: rotate(45deg);-webkit-transform: rotate(45deg);-moz-transform: rotate(45deg);}.heart:after,.heart:before{content: '';width: inherit;height: inherit;background: inherit;border-radius: 50%;-webkit-border-radius: 50%;-moz-border-radius: 50%;position: absolute;}.heart:after{top: -5px;}.heart:before{left: -5px;}");
                attachEvent();
                gameloop();
            }

            function gameloop() {
                for(var i = 0; i < hearts.length; i++) {
                    if(hearts[i].alpha <= 0) {
                        document.body.removeChild(hearts[i].el);
                        hearts.splice(i, 1);
                        continue;
                    }
                    hearts[i].y--;
                    hearts[i].scale += 0.004;
                    hearts[i].alpha -= 0.013;
                    hearts[i].el.style.cssText = "left:" + hearts[i].x + "px;top:" + hearts[i].y + "px;opacity:" + hearts[i].alpha + ";transform:scale(" + hearts[i].scale + "," + hearts[i].scale + ") rotate(45deg);background:" + hearts[i].color;
                }
                requestAnimationFrame(gameloop);
            }

            function attachEvent() {
                var old = typeof window.οnclick === "function" && window.onclick;
                window.onclick = function(event) {
                    old && old();
                    createHeart(event);
                }
            }

            function createHeart(event) {
                var d = document.createElement("div");
                d.className = "heart";
                hearts.push({
                    el: d,
                    x: event.clientX - 5,
                    y: event.clientY - 5,
                    scale: 1,
                    alpha: 1,
                    color: randomColor()
                });
                document.body.appendChild(d);
            }

            function css(css) {
                var style = document.createElement("style");
                style.type = "text/css";
                try {
                    style.appendChild(document.createTextNode(css));
                } catch(ex) {
                    style.styleSheet.cssText = css;
                }
                document.getElementsByTagName('head')[0].appendChild(style);
            }

            function randomColor() {
                return "rgb(" + (~~(Math.random() * 255)) + "," + (~~(Math.random() * 255)) + "," + (~~(Math.random() * 255)) + ")";
            }
        })(window, document);
    </script>
