以下代码放入全局文件即可

<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;}"),
