//1.初始化的时候要设置为一个空的数组
editData : {
headImageUrl: '',
nickName: '',
studentNumber: null,
sex: null,
dateOfBirth: '',
ilicenseNo: '',
nation: null,
appointmentTime: null,
politicsStatus: null,
nativePlace: null,
gradeClass: []
};
//2.自定义写rules
<el-form-item
label="年级班级"
prop="gradeClass"
:rules="[{ validator: (rule, value, callback)=>{checkClass(rule, value, callback,editData.gradeClass)}, message: '请选择年级班级', trigger: 'change',required: true}]">
<el-cascader
v-model="editData.gradeClass"
:options="optionsGradeClass"
:props="{ expandTrigger: 'hover' }"
></el-cascader>
</el-form-item>
//在method写好方法
//自定义验证
checkClass(rule, values, callback, data){
//自定义验证的逻辑
if(!this.editData.gradeClass || !this.editData.gradeClass.length ){
return callback(new Error(`请选择年级班级`));
}else{
return callback()
}
},
