iview Form表單校驗自定義校驗

• Form 組件基於 async-validator 實現的數據驗證，給 Form 設置屬性 rules，同時給需要驗證的 FormItem 設置屬性 prop 指向對應字段即可。
• 下面是完整代碼：

<template>

<script>
    export default {
        data () {
            return {
                formValidate: {
                    name: '',
                    mail: '',
                    city: '',
                    gender: '',
                    interest: [],
                    date: '',
                    time: '',
                    desc: ''
                },
                ruleValidate: {
                    name: [
                        { required: true, message: 'The name cannot be empty', trigger: 'blur' }
                    ],
                    mail: [
                        { required: true, message: 'Mailbox cannot be empty', trigger: 'blur' },
                        { type: 'email', message: 'Incorrect email format', trigger: 'blur' }
                    ],
                    city: [
                        { required: true, message: 'Please select the city', trigger: 'change' }
                    ],
                    gender: [
                        { required: true, message: 'Please select gender', trigger: 'change' }
                    ],
                    interest: [
                        { required: true, type: 'array', min: 1, message: 'Choose at least one hobby', trigger: 'change' },
                        { type: 'array', max: 2, message: 'Choose two hobbies at best', trigger: 'change' }
                    ],
                    date: [
                        { required: true, type: 'date', message: 'Please select the date', trigger: 'change' }
                    ],
                    time: [
                        { required: true, type: 'string', message: 'Please select time', trigger: 'change' }
                    ],
                    desc: [
                        { required: true, message: 'Please enter a personal introduction', trigger: 'blur' },
                        { type: 'string', min: 20, message: 'Introduce no less than 20 words', trigger: 'blur' }
                    ]
                }
            }
        },
        methods: {
            handleSubmit (name) {
                this.$refs[name].validate((valid) => {
                    if (valid) {
                        this.$Message.success('Success!');
                    } else {
                        this.$Message.error('Fail!');
                    }
                })
            },
            handleReset (name) {
                this.$refs[name].resetFields();
            }
        }
    }
</script>

• 如果下拉框是動態賦值 要加上類型 type：

city: [
                        { required: true, type:'number',message: 'Please select the city', trigger: 'change' }
                    ],

• 自定義校驗

1. 這裏是驗證手機號，在data下面加上以上代碼

const validatePhone = (rule, value, callback) => {
                if (!value) {
                    return callback(new Error('聯繫電話不能爲空'));
                } else if (!(/^1[3456789]\d{9}$/.test(value)) && !(/^((0\d{2,3})-)(\d{7,8})(-(\d{3,}))?$/.test(value))) {
                    callback('聯繫電話格式不正確');
                } else {
                    callback();
                }
            };
          

2. 在ruleValidate裏面使用上面自定義校驗的函數

phone: [
                        { required: true,validator:validatePhone,trigger:'blur'}
                    ]
