【已解决】ECharts中如何在点击事件函数中获得额外的自定义数据

ECharts crifan 1037浏览 0评论

ECharts中,对于配置:

    let curEchartsOption = {
     。。。
      series:
      [
        {
          name: CUSTOMER_SOURCE.DCC.name,
          type: ‘bar’,
          stack: ‘总量’,
          label: {
            normal: {
              show: true,
              position: ‘inside’
            }
          },
          itemStyle: {
            normal: {
              color: ValueColor.DARK_BLUE
            }
          },
          // data: [dccNum]
          data: [
            {
              name: CUSTOMER_SOURCE.DCC.name,
              value: dccNum
            }
          ]
        },
        {
          name: CUSTOMER_SOURCE.TEL.name,
          type: ‘bar’,
          stack: ‘总量’,
          label: {
            normal: {
              show: true,
              position: ‘inside’
            }
          },
          itemStyle: {
            normal: {
              color: ValueColor.GREEN
            }
          },
          // data: [telNum]
          data: [
            {
              name: CUSTOMER_SOURCE.TEL.name,
              value: telNum
            }
          ]
        },
。。。
  onCompleteProgressClick(e){
    console.log(‘onCompleteProgressClick: e=’, e);
    let newByModelDict = this.state.newAddByModelDict;
    newByModelDict.isFiltered = true;
    let newByConsultantDict = this.state.newAddByConsultantDict;
    newByConsultantDict.isFiltered = true;
    this.setState({
      newAddByModelDict: newByModelDict,
      newAddByConsultantDict: newByConsultantDict
    });
  }
  onClickCompleteProgressEvents = {
    // Note: must bind this here, Not in constructor otherwise not find this
    // ‘click’: this.onCompleteProgressClick
    ‘click’: this.onCompleteProgressClick.bind(this)
  }
                  <div className=”chart”>
                    <ReactEcharts
                      option={this.state.completeProgressDict.echartsOption}
                      style={{height: ‘200px’, width: ‘100%’}}
                      onEvents={this.onClickCompleteProgressEvents}
                      />
                  </div>

然后点击事件中,是可以获得对应的event的信息的,其中包括了name和value:

但是此处希望:

除了name和value之外,还可以给data中每个对象添加自定义的属性和值

但是看了看官网的定义中,只有已知的属性:

name

value

label

等等:

没有支持自定义的属性(用于保存此处的type,值为:10031001)

然后自己去试试,直接加到data中的:

const CUSTOMER_SOURCE = {
  DCC: {
    name: ‘DCC’,
    type: 10031001,
  },
          data: [
            {
              name: CUSTOMER_SOURCE.DCC.name,
              value: dccNum,
              type: CUSTOMER_SOURCE.DCC.type,
            }
          ]

结果还真的是可以获得的:

所以能推测出:

【总结】

此处设置series中的data(列表)中的每个对象,系统是直接赋值给内部属性的,比如常见的:

name和value

对应着官网的API中的参数:

http://echarts.baidu.com/option.html#series-bar.data.name

但是除此之外的其他自己定义的属性名,比如下面再去试试customerSourceType,ECharts可以自动忽略,重点的是:不会报错。

且还可以:

在点击事件回调函数中,可以返回对应的原先的dict值。

比如再去试试:

          data: [
            {
              name: CUSTOMER_SOURCE.DCC.name,
              value: dccNum,
              customerSourceType: CUSTOMER_SOURCE.DCC.type,
            }
          ]

效果:
