前言：
此时你们对“js的random函数”大体比较着重，我们都需要分析一些“js的random函数”的相关内容。那么小编在网上收集了一些对于“js的random函数””的相关内容，希望我们能喜欢，大家一起来了解一下吧！一、生成随机颜色
const generateRandomHexColor = () => `#${Math.floor(Math.random() * 0xffffff).toString(16)}`console.log(generateRandomHexColor())二、数组重排序const shuffle = (arr) => arr.sort(() => Math.random() - 0.5)const arr = [1, 2, 3, 4, 5]console.log(shuffle(arr))三、复制到剪切板
const copyToClipboard = (text) => navigator.clipboard && navigator.clipboard.writeText && navigator.clipboard.writeText(text)copyToClipboard("Hello World!")四、检测暗色主题const isDarkMode = () => window.matchMedia && window.matchMedia("(prefers-color-scheme: dark)").matches;console.log(isDarkMode())五、平滑滚动到顶部const scrollToTop = (element) => element.scrollIntoView({ behavior: "smooth", block: "start" });六、平滑滚动到底部const scrollToBottom = (element) => element.scrollIntoView({ behavior: "smooth", block: "end" });七、检测元素是否在屏幕中const callback = (entries) => { entries.forEach((entry) => { if (entry.isIntersecting) { console.log(`${entry.target.id} is visible`); } });};const options = { threshold: 1.0,};const observer = new IntersectionObserver(callback, options);const btn = document.getElementById("btn");const bottomBtn = document.getElementById("bottom-btn");observer.observe(btn);observer.observe(bottomBtn);八、检测设备UAconst detectDeviceType = () => /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test( navigator.userAgent ) ? "Mobile" : "Desktop";console.log(detectDeviceType());九、从 URL 中获取参数
const getParamByUrl = (key) => { const url = new URL(location.href) return url.searchParams.get(key)}十、深拷贝对象const deepCopy = obj => JSON.parse(JSON.stringify(obj))
