使用方法

javascript 复制代码

<div id="app"></div>
<script type="module" src="/src/main.ts">
import { autoScale } from './autoScale.js'
autoScale('#app', {
  width: 1920,
  height: 1080
})
  </script>

autoScale.js

javascript 复制代码

function debounce(fn, delay) {
let timer
return function () {
clearTimeout(timer);
timer = setTimeout(() => {
fn.apply(this, arguments);
}, delay);
};
}

export function autoScale(selector,options) {
const el = document.querySelector(selector);
const {width,height} = options; 

el.style.transformOrigin = "top left";
el.style.transition = "transform 0.5s"
function init(){
const scaleX = innerWidth / width
const scaleY = innerHeight / height
const scale = Math.min(scaleX, scaleY);

const left = (innerWidth - width * scale) / 2
const top = (innerHeight - height * scale) / 2
el.style.transform = ` translate(${left}px,${top}px) scale(${scale})`
}
init()
addEventListener("resize", debounce(init,200))
}
