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。

第一种：

<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;}"),
            n(),
            r()
    } (window, document);
</script>

第二种：

<script>
    var a_idx = 0;
    jQuery(document).ready(function($) {
        $("body").click(function(e) {
            var a = new Array("富强", "民主", "文明", "和谐", "自由", "平等", "公正" ,"法治", "爱国", "敬业", "诚信", "友善");
            var $i = $("<span/>").text(a[a_idx]);
            a_idx = (a_idx + 1) % a.length;
            var x = e.pageX,
            y = e.pageY;
            $i.css({
                "z-index": 999999999999999999999999999999999999999999999999999999999999999999999,
                "top": y - 20,
                "left": x,
                "position": "absolute",
                "font-weight": "bold",
                "color": "#ff6651"
            });
            $("body").append($i);
            $i.animate({
                "top": y - 180,
                "opacity": 0
            },
            1500,
            function() {
                $i.remove();
            });
        });
    });
</script>

背景特效：

<script>!function(){function n(n,e,t){return n.getAttribute(e)||t}function e(n){return document.getElementsByTagName(n)}function t(){var t=e("script"),o=t.length,i=t[o-1];return{l:o,z:n(i,"zIndex",-1),o:n(i,"opacity",.5),c:n(i,"color","0,0,0"),n:n(i,"count",99)}}function o(){a=m.width=window.innerWidth||document.documentElement.clientWidth||document.body.clientWidth,c=m.height=window.innerHeight||document.documentElement.clientHeight||document.body.clientHeight}function i(){r.clearRect(0,0,a,c);var n,e,t,o,m,l;s.forEach(function(i,x){for(i.x+=i.xa,i.y+=i.ya,i.xa*=i.x>a||i.x<0?-1:1,i.ya*=i.y>c||i.y<0?-1:1,r.fillRect(i.x-.5,i.y-.5,1,1),e=x+1;e<u.length;e++)n=u[e],null!==n.x&&null!==n.y&&(o=i.x-n.x,m=i.y-n.y,l=o*o+m*m,l<n.max&&(n===y&&l>=n.max/2&&(i.x-=.03*o,i.y-=.03*m),t=(n.max-l)/n.max,r.beginPath(),r.lineWidth=t/2,r.strokeStyle="rgba("+d.c+","+(t+.2)+")",r.moveTo(i.x,i.y),r.lineTo(n.x,n.y),r.stroke()))}),x(i)}var a,c,u,m=document.createElement("canvas"),d=t(),l="c_n"+d.l,r=m.getContext("2d"),x=window.requestAnimationFrame||window.webkitRequestAnimationFrame||window.mozRequestAnimationFrame||window.oRequestAnimationFrame||window.msRequestAnimationFrame||function(n){window.setTimeout(n,1e3/45)},w=Math.random,y={x:null,y:null,max:2e4};m.id=l,m.style.cssText="position:fixed;top:0;left:0;z-index:"+d.z+";opacity:"+d.o,e("body")[0].appendChild(m),o(),window.onresize=o,window.onmousemove=function(n){n=n||window.event,y.x=n.clientX,y.y=n.clientY},window.onmouseout=function(){y.x=null,y.y=null};for(var s=[],f=0;d.n>f;f++){var h=w()*a,g=w()*c,v=2*w()-1,p=2*w()-1;s.push({x:h,y:g,xa:v,ya:p,max:6e3})}u=s.concat([y]),setTimeout(function(){i()},100)}();</script>
