Echarts 服务器端刷新前端Echarts图表

1.前端页面js需要定义一个常量

 var dom = document.getElementById("container2");
        var myChart = echarts.init(dom);
        var option = (@Html.Raw(ViewBag.Echart));  //常量
        myChart.setOption(option); //这个是关键方法

        //多个图标随着web窗体的改变而改变
        window.addEventListener("resize", function () {
        myChart.resize();
        });

2.服务器端调用前端JS,以FineUI为例

  PageContext.RegisterStartupScript(" myChart.clear();myChart.setOption(" + echartStr + ");");
            return UIHelper.Result();

3.Vue中使用

     var myChart = this.$echarts.init(document.getElementById("myChart"));
      myChart.showLoading();
      myChart.hideLoading();
      myChart.setOption({
        title: { text: "在Vue中使用echarts" },
        tooltip: {},
        xAxis: {
          data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"],
        },
        yAxis: {},
        series: [
          {
            name: "销量",
            type: "bar",
            data: [5, 20, 36, 10, 10, 20],
          },
        ],
      });
         window.onresize=myChart.resize;  //这行代码自适应
