js特效:点击鼠标位置漂浮心形图案随机变色

这篇笔记分享一个点击鼠标时漂浮随机变颜色的心形，用在网页上面非常漂亮。先看下预览图：

JS特效源码：

! function (e, t, a) {
function n() {
c(".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: fixed;}.heart:after{top: -5px;}.heart:before{left: -5px;}"), o(), r()
}
function r() {
for (var e = 0; e < d.length; e++) d[e].alpha <= 0 ? (t.body.removeChild(d[e].el), d.splice(e, 1)) : (d[e].y--, d[e].scale += .004, d[e].alpha -= .013, d[e].el.style.cssText = "left:" + d[e].x + "px;top:" + d[e].y + "px;opacity:" + d[e].alpha + ";transform:scale(" + d[e].scale + "," + d[e].scale + ") rotate(45deg);background:" + d[e].color + ";z-index:99999");
requestAnimationFrame(r)
}
function o() {
var t = "function" == typeof e.onclick && e.onclick;
e.onclick = function (e) {
t && t(), i(e)
}
}
function i(e) {
var a = t.createElement("div");
a.className = "heart", d.push({
el: a,
x: e.clientX - 5,
y: e.clientY - 5,
scale: 1,
alpha: 1,
color: s()
}), t.body.appendChild(a)
}
function c(e) {
var a = t.createElement("style");
a.type = "text/css";
try {
a.appendChild(t.createTextNode(e))
} catch (t) {
a.styleSheet.cssText = e
}
t.getElementsByTagName("head")[0].appendChild(a)
}
function s() {
return "rgb(" + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + ")"
}
var d = [];
e.requestAnimationFrame = function () {
return e.requestAnimationFrame || e.webkitRequestAnimationFrame || e.mozRequestAnimationFrame || e.oRequestAnimationFrame || e.msRequestAnimationFrame || function (e) {
setTimeout(e, 1e3 / 60)
}
}(), n()
}(window, document);
