使用非常简单，需要在哪个页面显示就把代码放到哪个页面就行。
<script>
!function(e, t, a) {
function r() {
for (var e = 0; e < s.length; e++) s[e].alpha <= 0 ? (t.body.removeChild(s[e].el), s.splice(e, 1)) : (s[e].y--, s[e].scale += .004, s[e].alpha -= .013, s[e].el.style.cssText = \"left:\" + s[e].x + \"px;top:\" + s[e].y + \"px;opacity:\" + s[e].alpha + \";transform:scale(\" + s[e].scale + \",\" + s[e].scale + \") rotate(45deg);background:\" + s[e].color + \";z-index:99999\");
requestAnimationFrame(r)
}
function n() {
var t = \"function\" == typeof e.onclick && e.onclick;
e.onclick = function(e) {
t && t(),
o(e)
}
}
function o(e) {
var a = t.createElement(\"div\");
a.className = \"heart\",
s.push({
el: a,
x: e.clientX - 5,
y: e.clientY - 5,
scale: 1,
alpha: 1,
color: c()
}),
t.body.appendChild(a)
}
function i(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 c() {
return \"rgb(\" + ~~ (255 * Math.random()) + \",\" + ~~ (255 * Math.random()) + \",\" + ~~ (255 * Math.random()) + \")\"
}
var s = [];
e.requestAnimationFrame = e.requestAnimationFrame || e.webkitRequestAnimationFrame || e.mozRequestAnimationFrame || e.oRequestAnimationFrame || e.msRequestAnimationFrame ||
function(e) {
setTimeout(e, 1e3 / 60)
},
i(\".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;}\"),
