底层源码：

handleClearClick(event) {
        this.deleteSelected(event);
      },
deleteSelected(event) {
        event.stopPropagation();
        const value = this.multiple ? [] : '';
        this.$emit('input', value);
        this.emitChange(value);
        this.visible = false;
        this.$emit('clear');
      },

删除

<div>
        <el-select
          v-model="data"
          clearable
          placeholder="请选择"
          size="small"
          @clear="remove(tagNumber)"
          @change="">
          <el-option
            v-for="option in list"
            :key="option.id"
            :label="option.name"
            :value="option.id">
            {{ option.name  }}
          </el-option>
        </el-select>
      </div>

方法：

remove(tagNumber) { 
      // console.log(event)
      // 业务逻辑
      
    }
