win10默認設置150%,對頁面布局的影響靠單純的自適應是沒辦法解決的
解決方案一
css解決(復制粘貼放在樣式文件中,確保被加載)
@media all and (-moz-min-device-pixel-ratio: 1.09) and (-moz-max-device-pixel-ratio: 1.18), (-webkit-min-device-pixel-ratio: 1.09) and (-webkit-max-device-pixel-ratio: 1.18), (min-resolution: 1.09dppx) and (max-resolution: 1.18dppx) { :root { font-size: 14px; } } @media all and (-moz-min-device-pixel-ratio: 1.19) and (-moz-max-device-pixel-ratio: 1.28), (-webkit-min-device-pixel-ratio: 1.19) and (-webkit-max-device-pixel-ratio: 1.28), (min-resolution: 1.19dppx) and (max-resolution: 1.28dppx) { :root { font-size: 13px; } } @media all and (-moz-min-device-pixel-ratio: 1.29) and (-moz-max-device-pixel-ratio: 1.4), (-webkit-min-device-pixel-ratio: 1.29) and (-webkit-max-device-pixel-ratio: 1.4), (min-resolution: 1.29dppx) and (max-resolution: 1.4dppx) { :root { font-size: 12px; } } @media all and (-moz-min-device-pixel-ratio: 1.41) and (-moz-max-device-pixel-ratio: 1.6), (-webkit-min-device-pixel-ratio: 1.41) and (-webkit-max-device-pixel-ratio: 1.6), (min-resolution: 1.41dppx) and (max-resolution: 1.6dppx) { :root { font-size: 10px; } } @media all and (-moz-min-device-pixel-ratio: 1.61) and (-moz-max-device-pixel-ratio: 1.8), (-webkit-min-device-pixel-ratio: 1.61) and (-webkit-max-device-pixel-ratio: 1.8), (min-resolution: 1.61dppx) and (max-resolution: 1.8dppx) { :root { font-size: 9px; } } @media all and (-moz-min-device-pixel-ratio: 1.81) and (-moz-max-device-pixel-ratio: 2.1), (-webkit-min-device-pixel-ratio: 1.81) and (-webkit-max-device-pixel-ratio: 2.1), (min-resolution: 1.81dppx) and (max-resolution: 2.1dppx) { :root { font-size: 8px; } }
解決方案二?
這種方式會將頁面的元素進行縮放
js解決(放在入口文件中)
export const detectZoom = () => { let ratio = 0, screen = window.screen, ua = navigator.userAgent.toLowerCase(); if (window.devicePixelRatio !== undefined) { ratio = window.devicePixelRatio; } else if (~ua.indexOf('msie')) { if (screen.deviceXDPI && screen.logicalXDPI) { ratio = screen.deviceXDPI / screen.logicalXDPI; } } else if ( window.outerWidth !== undefined && window.innerWidth !== undefined ) { ratio = window.outerWidth / window.innerWidth; } if (ratio) { ratio = Math.round(ratio * 100); } return ratio; };
比如React項目中的app.js
app.js
import { detectZoom } from '@/utils/detectZoom'; // 處理筆記本系統默認系統比例為150%帶來的布局影響 const m = detectZoom(); document.body.style.zoom = 100 / Number(m);
