动态改变echarts大小,通过监听窗口实现

<template>
<div id="echartsDOM"></div>
</template>
<script>
import echarts from "echarts";
export default {  
    data(){
          return {
                 lineCharts: null;
          }
    },
    methods:{},
    mounted(){
        this.$nextTick(()=>{
              this.lineCharts = echarts.init(document.getElementById('echartsDOM'));
        })
        window.onresize = () => {
            this.lineCharts.resize({
                width:document.getElementById('echartsDOM').getBoundingClientRect().width
            });
        };
    }
    
}
</script>
