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。

	!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;}"),
			n(),
			r()
	} (window, document);
