纯代码实现WordPress网站底部渐变滚动公告

现在很多插件都可以实现公告功能，用来提示重要信息，但这些插件都会向数据库中写入数据，并频繁读取数据库，对网站并不怎么友好。

站长分享一种简单的WordPres纯代码实现底部渐变滚动公告的方法。

代码是自适应的，放在很多地方都可以用。

<div id="chakhsu" style="text-align: center; color: green;"></div>    
<script>var chakhsu = function (r) {    
        function t() {    
            return b[Math.floor(Math.random() * b.length)]    
        }    
        function e() {    
            return String.fromCharCode(94 * Math.random() + 33)    
        }    
        function n(r) {    
            for (var n = document.createDocumentFragment(), i = 0; r > i; i++) {    
                var l = document.createElement("span");    
                l.textContent = e(), l.style.color = t(), n.appendChild(l)    
            }    
            return n    
        }    
        function i() {    
            var t = o[c.skillI];    
            c.step ? c.step-- : (c.step = g, c.prefixP < l.length ? (c.prefixP >= 0 && (c.text += l[c.prefixP]), c.prefixP++) : "forward" === c.direction ? c.skillP < t.length ? (c.text += t[c.skillP], c.skillP++) : c.delay ? c.delay-- : (c.direction = "backward", c.delay = a) : c.skillP > 0 ? (c.text = c.text.slice(0, -1), c.skillP--) : (c.skillI = (c.skillI + 1) % o.length, c.direction = "forward")), r.textContent = c.text, r.appendChild(n(c.prefixP < l.length ? Math.min(s, s + c.prefixP) : Math.min(s, t.length - c.skillP))), setTimeout(i, d)    
        }    
        /*以下内容自定义修改*/    
        var l = "love- ",    
            o = ["感谢您的分享与赞赏，祝各位2024年，新年快乐，身体健康，万事如意”。", ].map(function (r) {    
                return r + ""    
            }), a = 2, g = 1, s = 5, d = 75,    
            b = ["rgb(110,64,170)", "rgb(150,61,179)", "rgb(191,60,175)", "rgb(228,65,157)", "rgb(254,75,131)", "rgb(255,94,99)", "rgb(255,120,71)", "rgb(251,150,51)", "rgb(226,183,47)", "rgb(198,214,60)", "rgb(175,240,91)", "rgb(127,246,88)", "rgb(82,246,103)", "rgb(48,239,130)", "rgb(29,223,163)", "rgb(26,199,194)", "rgb(35,171,216)", "rgb(54,140,225)", "rgb(76,110,219)", "rgb(96,84,200)"],    
            c = {text: "", prefixP: -s, skillI: 0, skillP: 0, direction: "forward", delay: a, step: g};    
        i()    
    };    
    chakhsu(document.getElementById('chakhsu'));</script>
