表单常用正则验证

1.去除空格

  //去除空格
  nameValidator(c: FormControl) {
    let NOT_NULL = /\s{0,}[\S]{1,}[\s\S]{0,}/;
    if (c.value) {
      if (!NOT_NULL.test(c.value)) {
        return { error: true, notnull: true };
      }
    }
  };

2.手机号正则

  // 手机号正则
  phoneValidator = (control: FormControl): { [s: string]: boolean } => {
    const EMAIL_REGEXP = /^1([358][0-9]|4[579]|66|7[0135678]|9[89])[0-9]{8}$/;
    if (!control.value) {
      return { required: true }
    } else if (!EMAIL_REGEXP.test(control.value)) {
      return { error: true, phoneNumber: true };
    }
  };

3.邮箱正则

  //邮箱正则
  emailValidator = (control: FormControl): { [s: string]: boolean } => {
    const EMAIL_REGEXP = /^[a-zA-Z0-9_-]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$/i;
    if (!control.value) {
      return { required: true }
    } else if (!EMAIL_REGEXP.test(control.value)) {
      return { error: true, email: true };
    }
