Vue实现大屏页面的屏幕自适应 Vue实现大屏页面的屏幕自适应

本文实例为大家分享了Vue实现大屏页面的屏幕自适应的具体代码，供大家参考，具体内容如下
1. 在配置文件设置大屏设计的尺寸1920*1080

//appConfig.jsexport default{screen:{width:1920,height:1080,scale:20}//大屏设计宽高}

2. 定义resetScreenSize.js

import appConfig from '../config/base' export function pageResize(callback) {let init = () => {console.log(window.innerHeight + "," + window.innerWidth); let _el = document.getElementById('app'); let hScale = window.innerHeight / appConfig.screen.height; let wScale = window.innerWidth / appConfig.screen.width; let pageH = window.innerHeight; let pageW = window.innerWidth; let isWider = (window.innerWidth / window.innerHeight) >= (appConfig.screen.width / appConfig.screen.height); console.log(isWider); if (isWider) {_el.style.height = window.innerHeight+'px'; // '100%'; _el.style.width = pageH * appConfig.screen.width / appConfig.screen.height + 'px'; _el.style.top='0px'; _el.style.left=(window.innerWidth -pageH * appConfig.screen.width / appConfig.screen.height)*0.5+'px'; console.log(_el.style.width + "," + _el.style.height)}else {_el.style.width = window.innerWidth+'px'; // '100%'; _el.style.height = pageW * appConfig.screen.height / appConfig.screen.width + 'px'; _el.style.top= 0.5*(window.innerHeight-pageW * appConfig.screen.height / appConfig.screen.width)+'px'; _el.style.left='0px'; console.log(_el.style.height); console.log(_el.style.top); }document.documentElement.style.fontSize =(_el.clientWidth / appConfig.screen.scale) + 'px'; }var resizeEvt = 'orientationchange' in window ? 'orientationchange' : 'resize'; window.addEventListener(resizeEvt, init, false); document.documentElement.addEventListener('DOMContentLoaded', init, false); init()}

3 使用方式
main.js 引入

import appConfig from './config/base.js'; Vue.prototype.appConfig=appConfig; app.Vue在mounted函数引入import{pageResize} from './utils/resetScreenSize' export default {name: 'App',data(){return{}},mounted(){pageResize(); console.log('pageResize'); }}

组件中样式 lang="stylus"

.mc{display :flex; flex-direction :column; align-content :center; justify-content :center; display: flex; flex: 1 1 auto; flex-direction: column; padding:(15/96)rem; } .leftC{width :(410/96)rem; } .centerC{width :(1060/96)rem; } .rightC{width :(450/96)rem; }

其中 96为配置文件中1920/20得来，这样不用在进行各种换算了
