如果要完整解決該縮放和布局問題,仍需適配,下面這篇文章主要給大家介紹了關(guān)于如何解決前端筆記本屏幕顯示縮放比例125%,150%對頁面布局的影響,需要的朋友可以參考下

發(fā)現(xiàn)問題

win10默認設(shè)置150%,對頁面布局的影響靠單純的自適應(yīng)是沒辦法解決的

問題出在device-pixel-ratio

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(tǒng)默認系統(tǒng)比例為150%帶來的布局影響
const m = detectZoom();
document.body.style.zoom = 100 / Number(m);
