Posted 2020-10-14 dongxiaolei

function chart(opt,id,chartName){//配置option的方法
    var chartName = echarts.init(document.getElementById(id));
    chartName.setOption(opt);
    window.onresize = chartName.resize;
   window.setTimeout(function(){
       $(".indexCon1-filter a").on(‘click‘,function(){
           var _body=$("body");
           chartName.animation="false";
           var picInfo = chartName.getImage();//picInfo为echarts图表转换后的img标签
           $(picInfo).addClass("canvasImg");
           if(!_body.hasClass("cImg")){
               _body.addClass("cImg")
           }
           $("#"+id).html(picInfo);
       })
   });
