vue-amap的marker点单击高亮

我使用vue-amap组件显示marker点，部分代码如下

<el-amap-marker v-for="marker in markers" :key="marker.index" :position="marker.position" :events="marker.events" ></el-amap-marker>

#####点击高亮的思路
我的思路是点击之后修改icon的样式，但该如何使得下次点击后前一次的图标变回蓝色呢
在下方method方法中的显示marker的方法中，点击事件e.target.setIcon(afticon);成功在点击后变换红色图标，结果如下

在vue的method中的部分代码

Point() {
      let markers = [];
      let windows1 = [];
      let srcLists1=[];
      let myicon=[];
      let that = this;
      let afticon=new AMap.Icon({
        //size: new AMap.Size(30, 35),//图标大小
        imageSize:new AMap.Size(35, 35),
        //image: "../../static/5.png"
        image: "//a.amap.com/jsapi_demos/static/demo-center/icons/poi-marker-red.png"
      });
      let beficon=new AMap.Icon({
        //size: new AMap.Size(19, 31),//图标大小
        imageSize:new AMap.Size(28, 28),
        //image:"../../static/7.png"
        image: "//a.amap.com/jsapi_demos/static/demo-center/icons/poi-marker-blue.png"
      });
      //let showed=e.target.setIcon(afticon);
      this.CollectPoint.forEach((item, index) => {
        markers.push({
          position: item.position,
          offset: new AMap.Pixel(-10, -10),
          icon:beficon, //不设置默认蓝色水滴
          events: {
            click(e) {
               //let showered=e.target.setIcon(afticon);
              that.srcList1 = that.srcLists1[index];
              // 方法：鼠标移动到点标记上，显示相应窗体
              that.windows1.forEach((window1) => {
                window1.visible = false; // 关闭窗体
              });
              that.window1 = that.windows1[index];
              that.$nextTick(() => {
                that.window1.visible = true;
                e.target.setIcon(afticon);
                that.$refs.map.$$getInstance().setZoomAndCenter(6,item.position)
              });
            },
          },
        });
        windows1.push({
          name:item.name,
          recorder:item.recorder,
          position: item.position,
          offset: [0, -20], // 窗体偏移
          showShadow: false,
          visible: false, // 初始是否显示
        });
        srcLists1.push({
          photos:item.url4,
          lont:item.lont,
          lat:item.lat,
          gaocheng:item.gaocheng,
          recorder:item.recorder,
          name:item.name,
          wea:item.weather,
          dtm:item.dtm,
          place:item.place,
        });
      });
      //  加点
      this.markers = markers;
      // 加弹窗
      this.windows1 = windows1;
      this.srcLists1 =srcLists1;
    }

但如何写使得点击下一个点之后，前一个点可以变回原来的蓝色图标，就是如何修改这个events中的click里的事件

先循环this.markers，把坐标全都变蓝，然后再setIcon把点击的变红

that.$nextTick(() => {
  that.window1.visible = true;
  that.markers.forEach(itemm=>{
    itemm.icon = beficon;
  })
  e.target.setIcon(afticon);
  that.$refs.map.$$getInstance().setZoomAndCenter(6,item.position)
});

获取当前map中所有点的layer 然后循环所有的点对象与当前点对象进行比对 如果比对成功则设置当前icon样式为红色 不成功则设置其他点icon为蓝色
