验证器回调中value值没有数据

复杂的响应式，导致回调中value值没有数据，最终还是通过手动判断获取值处理

• 原理没有搞清楚，为什么回调中value没有值
• 背景：动态增加了form表单的字段，通过for循环处理的。对每个新增的字段还要添加字段验证其。就出现了问题

<el-form-itemv-for="(role, index) in currentProject.roleUserMappings":key="role.roleId":label="role.roleName":prop="`roleUserMappings.${index}.selectedUserId`"><el-select v-model="role.selectedUserId" multiple placeholder="请选择用户"style="width: 200px;"@change="flush"><el-optionv-for="user in role.userList":key="user.userId":label="user.userName":value="user.userId"/></el-select>
</el-form-item>

updateRoleValidationRules() {const rules = {};this.currentProject.roleUserMappings.forEach((role, index) => {console.log('userid:', `roleUserMappings.${index}.selectedUserId`);this.$set(this.rules, `roleUserMappings.${index}.selectedUserId`, [{validator: (rule, value, callback) => {// console.log('value:',value, )const selectedUsers =this.currentProject.roleUserMappings[index].selectedUserId;if (!selectedUsers || selectedUsers.length === 0) {console.log('未选择用户')callback(new Error(`${role.roleName}必须选择用户`))// callback()} else {console.log('校验通过')callback()}},trigger: ['change', 'blur']}]);});}

• 修改了这里。获取值做了判断，没有用value

 const selectedUsers =this.currentProject.roleUserMappings[index].selectedUserId;if (!selectedUsers || selectedUsers.length === 0) {
