都采用单例模式,原生js实现es6
兼容老版本浏览器内核,请将用es6语法的地方做修改github
代码: 样式所有经过js建立style标签注入head中,若需修改,请修改loadignStyle和loadignChildStyle 的值即刻。web
const loading = (() => { let loadingEle = null return (status) => { if(!loadingEle) { const divEle = document.createElement('div') const styleEle = document.createElement('style') // 底部遮罩样式 const loadignStyle = '.loading{position: fixed;z-index: 1000;left: 0;top:0;width: 100%;height: 100%;background-color: rgba(0,0,0, .6)}' // loading动画样式 const loadignChildStyle = '.loading div{position: absolute;width: 30px;height: 30px;top: 50%;left: 50%;margin: -15px 0 0 -15px;border: 1px solid #fff;border-right: 1px solid transparent;border-radius: 50%;animation: loading 1s linear infinite;}' divEle.setAttribute('class', 'loading') divEle.innerHTML = '<div></div>' styleEle.innerHTML = `${loadignStyle} ${loadignChildStyle} @keyframes loading {to {transform: rotate(360deg)}}` document.querySelector('head').append(styleEle) document.querySelector('body').append(divEle) loadingEle = divEle } else { // 控制loading的显示与隐藏 const dispalyStatus = status ? 'block': 'none'; loadingEle.setAttribute('style', `display:${dispalyStatus}`) } } })()
任意可调用loading函数的地方调用即刻;显示传入参数true,不显示不传参数或传false。浏览器
const toast = (() => { let once = null let clearTime return (text, time) => { if(!time || time<1000 ) time = 1500 const updata = () => { once.innerHTML = text || '' once.setAttribute('style', 'position: fixed;left: 50%;z-index: 9000;max-width: 300px;padding: 5px 12px;-webkit-transform: translateX(-50%);text-align: center;border-radius: 4px;font-size: 14px;color: #fff;background-color: rgba(0,0,0,0.6);') clearTime = setTimeout(() => { once.setAttribute('style', 'display:none') clearTimeout(clearTime) }, time); } if(!once) { const bodyEle = document.querySelector('body') const div = document.createElement('div'); bodyEle.appendChild(div) once = div updata() } else { updata() } } })()
参数:text(弹窗文本) time(显示时常) 时间默认或小于1000时设置为1500毫秒app
任意可调用的地方调用 toast 方法便可函数
