Vue Realizes Screen Adaptation of Large Screen Pages

In this paper, we share the specific code of Vue to realize the screen adaptation of large screen pages for your reference. The specific contents are as follows

1. Set the size of the large screen design in the configuration file 1920*1080

//appConfig.js
export default{
    screen:{
        width:1920,
        height:1080,
        scale:20
    }// Large screen design width and height 
}

2. Define 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 Usage

Introduction of main. js

import appConfig from './config/base.js';
Vue.prototype.appConfig=appConfig;
app.Vue   In mounted Function introduction 

import  {pageResize} from './utils/resetScreenSize'
 
export default {
  name: 'App',
  data(){
    return{
       
    }
  },
  mounted(){
    pageResize();
    console.log('pageResize');
  }
}

Style lang= "stylus" in component

 .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;
    }

Among them, 96 is obtained from 1920/20 in the configuration file, so there is no need to carry out various conversions
