多次渲染报错 There is a chart instance already initialized on the dom

解决的办法就是先在页面卸载这个chart图表，再重新渲染一次

<div id="equipmentLocalization" style="width:100%; height: 400px;"></div>
var chartDom = document.getElementById('equipmentLocalization');
// 解决多次渲染报错
var myChart = echarts.init(chartDom).dispose();
myChart = echarts.init(chartDom);
var option;
option={};
option && myChart.setOption(option);
