为什么我们宽度设置了100%，结果变为了100px？

源码这里没有获取到clientWidth，会将设置的width:100%转换称100px 

解决办法：

<div ref="numberPieRef"></div>let numberPieRef = ref(null);
let myChart = null;function initChart() {if (numberPieRef.value) {numberPieRef.value.style.width = window.innerWidth - 300 + "px";numberPieRef.value.style.height = "500px";myChart = $eCharts.init(numberPieRef.value);myChart.showLoading();.....myChart.hideLoading();myChart.setOption({.........});window.addEventListener("resize", () => {myChart.resize();});}
}
