ElementPlus el-form多选框校验默认触发问题

multiple自动触发了change事件

      <el-form-item label="代码路径" prop="path_id">
            <el-select
                v-model="editform.path_id"
                clearable
                filterable
                multiple
                placeholder="代码路径"
            >
              <el-option
                  v-for="item in (selectsData?.codePathData || [])"
                  :key="item.id+''"
                  :label="item.path"
                  :value="item.id+''"
              />
            </el-select>
          </el-form-item>

使用校验增加开关判断（每次开启时记得初始化开关）；

const pathIdFirst = ref(true);
const rules = reactive<FormRules>({
  path_id: [
    {
      required: true, message: '请选择代码路径', trigger: 'change', validator: (rule, val, cb) => {
        if (!pathIdFirst.value) {
          if (val.length === 0) {
            cb(new Error('请选择代码路径'));
          } else {
            cb();
          }
        } else {
          pathIdFirst.value = false;
          cb();
        }
      }
    },
  ],
 
})
