Vue3 echarts 组件化使用 resizeObserver

点击查看代码

const resizeObserver = ref(null);
//进行初始化和监听窗口变化
onMounted(async () => {
  await nextTick(() => {
    initChart();
    setOptions(options.value, opts.value ?? true);
  });
  window.addEventListener('resize', handleResize);
  resizeObserver = new ResizeObserver(() => handleResize);
  resizeObserver.observe($el);
});
//调用echarts的resize方法
//charts.value是通过 echarts.init 创建的实例。
const handleResize = () => {
  if (!charts.value) return;
  charts.value.resize();
};
//销毁前移除监听
onBeforeUnmount(() => {
  window.removeEventListener('resize', handleResize);
  resizeObserver.disconnect();
});
