progress/index.js
const controller = {
init: require('./controllers/html'),
speed: require('./controllers/speed')
}
exports.init = controller.init
exports.speed = controller.speedprogress/controllers/html/index.js
exports.set = () => {
let dom = document.createElement('div')
dom.setAttribute('id', 'progress_speed')
dom.classList.add('progress-box', 'progress-hide')
dom.innerHTML = '<div class="progress progress-speed-hide" id="progress_box_speed"><div class="speed" style="width:0%;background: #f2f3f5;transition: 0.2s;"></div></div>'
document.getElementById('app').insertBefore(dom, document.getElementById('app').firstChild)
let Style = `

}`
let styleElement = document.getElementById('progress')
if (!styleElement) {
styleElement = document.createElement('style')
styleElement.type = 'text/css'
styleElement.id = 'progress'
document.getElementsByTagName('head')[0].appendChild(styleElement)
styleElement.appendChild(document.createTextNode(Style))
}
}progress/controllers/speed/index.js
exports.run = (time) => {
document.getElementById('progress_speed').classList.remove('progress-hide')
time = time * 100
let dom = document.getElementById('progress_box_speed')
dom.classList.remove('progress-speed-hide')
dom.getElementsByClassName('speed')[0].classList.remove('speed-success')
setTimeout(() => {
dom.getElementsByClassName('speed')[0].setAttribute('style', 'width:' + time + '%')
}, 10)
if (time >= 100) {
setTimeout(() => {
dom.getElementsByClassName('speed')[0].classList.add('speed-success')
dom.getElementsByClassName('speed')[0].setAttribute('style', 'width:100%')
dom.classList.add('progress-speed-hide')
setTimeout(() => {
document.getElementById('progress_speed').classList.add('progress-hide')
dom.getElementsByClassName('speed')[0].setAttribute('style', 'width:0%')
}, 900)
}, 1000)
}
}如何使用？
main.js中导入（根据你自己新建文件的路径为基准，这是我自己的路径）
import progress from './common/progress'全局挂载
Vue.prototype.$progress = progress结构
使用：
this.$progress.init.set()
this.$progress.speed.run('10.555555') // 这样进度条就走到10.555555%了
进度条走到100之后，会自动隐藏！可以全局挂载，然后各种需要进度条的地方再使用！
