##鼠标神效 ```javascript <script type="text/javascript"> 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": 99999999999999999999999999999, "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> ``` ##离开和进入html时改变title ```javascript <script type="javascript"> var OriginTitile = document.title; var titleTime; document.addEventListener('visibilitychange', function() { if (document.hidden) { document.title = '(つェ⊂)人呢?快回来! ' + OriginTitile; clearTimeout(titleTime); } else { document.title = '(*´∇｀*) 你来啦~ ' + OriginTitile; titleTime = setTimeout(function() { document.title = OriginTitile; }, 2000); } }); </script> ``` ##显示网页运行时间 ```javascript <script type="javascript"> function show_runtime(){ window.setTimeout("show_runtime()",1000); X=new Date("08/06/2019 16:22:00"); Y=new Date();T=(Y.getTime()-X.getTime());M=24*60*60*1000; a=T/M; A=Math.floor(a); b=(a-A)*24; B=Math.floor(b); c=(b-B)*60; C=Math.floor((b-B)*60); D=Math.floor((c-C)*60); runtime_span.innerHTML="本站勉强运行: "+A+"天"+B+"小时"+C+"分"+D+"秒"}show_runtime(); </script> ``` 然后在需要显示运行时间的地方加上以下代码即可。 `<span id="runtime_span"></span>` Last modification：September 20th, 2019 at 03:52 pm © 允许规范转载 Support 如果觉得我的文章对你有用，请随意赞赏 Appreciate the author 支付宝微信

这个真的挺有趣的，点一下鼠标就会有提示٩(ˊᗜˋ*)و
好多的干货
离开和进入html时改变title 这个代码放在哪里 我添加了没有显示
自定义JS里面，需要删除script标签
受教了
非常不错呢~
可以尝试一下吼
