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了。
- <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;}"),
