  message: '请输入正确的手机号',
  trigger: 'blur'
}

3. 纯整数校验

export const integer = {
  pattern: /^(\-|\+)?\d+?$/,
  message: '请输入正确的数字',
  trigger: 'blur'
}

4. 纯整数或小数校验

export const float = {

  message: '请输入正确的营业执照',
  trigger: 'blur'
};

9. 字符长度校验

export function len(max = 255, min = 0) {
  return {

    message: `长度在 ${min} 到 ${max} 个字符`,
    trigger: 'blur'
  }
}

10. 数字范围校验

export function range(max = 99999999.99, min = 0) {
  const validator = (rule, val, cb) => {
    val = +val
    if (!(val >= min && val <= max)) {
      cb(new Error(rule.message))
    }
    cb()
  }
  return {
    validator,
    message: `数字范围在 ${min} 到 ${max}`,
    trigger: 'blur'

    if (!value) {
      cb(new Error('收款账户不能为空'))
    } else if (!Number.isInteger(+value)) {
      cb(new Error('银行卡号必须全为数字'))
    } else if (value.trim().length < 12 || value.trim().length > 19) {
      cb(new Error('银行卡号长度必须在12到19之间'))
    } else if (strBin.indexOf(value.substring(0, 2)) === -1) {
      cb(new Error('银行卡号开头6位不符合规范'))
    } else {
      cb();
    }

  };
