vue效果之改element的el-checkbox-group多选框组为单选可取消的单选框(样式还是多选框的样式)

vue

<el-checkbox-group v-model="listThematicChecked">
        <el-checkbox v-for="(item , index) in subjectList" @change="clickThematicMapItem(item,index)" :key="item.menu" :label="item.menu" :disabled="item.menu === '责任区' && disabledZeRenQu">
          <img :src="item.img" alt="" />&nbsp;&nbsp;{{ item.menu }}
          <em class="four-more-em" v-show="item.menu == '辖区态势图' || item.menu == '四色预警图'" @click.prevent="fourClick(item)">...</em>
        </el-checkbox>
      </el-checkbox-group>

后面...的点击效果，如果当前为勾选状态，点击...为切换另外一种区域图，再点击就是切换到勾选的那个区域图

  fourClick(data, fourMoreEm) {
      console.log('259', this.subjectList);
      if (data.isCheck === true) {
        console.log(data);
        switch (data.type) {
          //辖区态势
          case 'taishitu':
            this.$parent.$refs.dsMap.clearTrailLine();
            this.$parent.$refs.dsMap.clearFeatures('taishitu');
            // this.subjectList[3].isCheck = false;
            // this.subjectList[0].isCheck = true;
            if (data.fourMoreEm === false) {
              this.$parent.$refs.dsMap.readTsFeatures(allData, 'taishitu');
            } else {
              this.$parent.$refs.dsMap.readTsFeatures(tsData, 'taishitu');
            }
            this.$parent.$refs.dsMap.clearFeatures('tongjitu');
            this.$parent.$refs.dsMap.clearFeatures('sisetu');
            this.$parent.$refs.dsMap.clearHotFeatures('relitu');
            this.$parent.$refs.dsMap.clearHotFeatures('jingqingtu');

            break;
          //四色
          case 'sisetu':
            this.$parent.$refs.dsMap.clearTrailLine();
            this.$parent.$refs.dsMap.clearFeatures('sisetu');
            // this.subjectList[0].isCheck = false;
            // this.subjectList[3].isCheck = true;
            if (data.fourMoreEm === false) {
              this.$parent.$refs.dsMap.readTsFeatures(allData, 'sisetu');
            } else {
              this.$parent.$refs.dsMap.readTsFeatures(tsData, 'sisetu');
            }
            this.$parent.$refs.dsMap.clearFeatures('taishitu');
            this.$parent.$refs.dsMap.clearFeatures('tongjitu');
            this.$parent.$refs.dsMap.clearHotFeatures('relitu');
            this.$parent.$refs.dsMap.clearHotFeatures('jingqingtu');
            break;
        }
        data.fourMoreEm = !data.fourMoreEm;
      } else {
        console.log('我是f');
      }
    },

思路解析：

点击多选组件,

1>当前点击的这个对象和整个原始list去匹配，如果相同则让当前计数器isqx 加1,以及状态isCheck为true代表被选中;否则就是else里面的;

2>当相同的一个再点击一次，代表的是这个多选取消的效果，这个时候，计数器isqx加了1后就是2;然后走进判断

if (res.isqx == 2) {
            res.isqx = 0;
            check = false;
          } else if (res.isqx == 1) {
            check = true;
          }

然后用check去判断到底是取消还是选上的状态;
