echarts大屏如何实现自适应缩放

核心代码

const dataScreenRef = (ref < HTMLElement) | (null > null);onMounted(() => {if (dataScreenRef.value) {dataScreenRef.value.style.transform = `scale(${getScale()}) translate(-50%, -50%)`;}console.log("dataScreenRef ========> ", dataScreenRef);window.addEventListener("resize", resize);
});// 设置响应式
const resize = () => {if (dataScreenRef.value) {dataScreenRef.value.style.transform = `scale(${getScale()}) translate(-50%, -50%)`;console.log(1111);}
};// 根据浏览器大小推断缩放比例
const getScale = (width = 1920, height = 1080) => {let ww = window.innerWidth / width;let wh = window.innerHeight / height;return ww < wh ? ww : wh;
};
