Code

将以下 js script 放置在 body 任意位置，随后在你喜欢的位置放置 id 为 saintwei 的元素。

  1. <p style="text-align:center" id="saintwei"></p>
  3. <script>
  4.    var saintwei = function (r) {
  5.        function t() {
  6.            return b[Math.floor(Math.random() * b.length)]
  7.        }
  8.        function e() {
  9.            return String.fromCharCode(94 * Math.random() + 33)
  10.        }
  11.        function n(r) {
  12.            for (var n = document.createDocumentFragment(), i = 0; r > i; i++) {
  13.                var l = document.createElement("span");
  14.                l.textContent = e(), l.style.color = t(), n.appendChild(l)
  15.            }
  16.            return n
  17.        }
  18.        function i() {
  19.            var t = o[c.skillI];
