el-input的rules驗證

 rules: {
        appraisalType: [{ required: true, message: "考核類型必選" }],
        subModelName: [
          { required: true, message: "請輸入部門名稱", trigger: "blur" },
          { max: 30, message: "長度在30 個字符以內", trigger: "blur" },

前端Vue中常用rules校驗規則:

1、是否合法IP地址:

pattern:/^(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])\.(\d{1,2}|1\d\d|2[0-4]\d|25[0-5])$/,

2.是否手機號碼或者固話
pattern:/^((0\d{2,3}-\d{7,8})|(1[34578]\d{9}))$/,

3. 是否身份證號碼
pattern:/(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/,

4.是否郵箱
pattern:/^([a-zA-Z0-9]+[-_\.]?)+@[a-zA-Z0-9]+\.[a-z]+$/,

5.整數填寫
pattern:/^-?[1-9]\d*$/,

6.正整數填寫
pattern:/^[1-9]\d*$/,

7.小寫字母
pattern:/^[a-z]+$/,

8.大寫字母
pattern:/^[A-Z]+$/,

9.大小寫混合
pattern:/^[A-Za-z]+$/,

10.多個8位數字格式(yyyyMMdd)並以逗號隔開
pattern:/^\d{8}(\,\d{8})*$/,

11.數字加英文，不包含特殊字符
pattern:/^[a-zA-Z0-9]+$/,

12.前兩位是數字后一位是英文
pattern:/^\d{2}[a-zA-Z]+$/,

13.密碼校驗（6-20位英文字母、數字或者符號（除空格），且字母、數字和標點符號至少包含兩種）
pattern:/^(?![\d]+$)(?![a-zA-Z]+$)(?![^\da-zA-Z]+$)([^\u4e00-\u9fa5\s]){6,20}$/,

14.中文校驗
pattern:/^[\u0391-\uFFE5A-Za-z]+$/,
