Validate.js ReGex 未按預期工作

Question

我正在嘗試使用格式：模式：Validate.js 的功能來確保密碼滿足至少一個大寫、一個小寫、一個數字和一個特殊字符的要求，最小長度為 8 和最大為 20。存在和長度功能如預期。 有人有任何提示嗎？

 password: {
    presence: {
      allowEmpty: false,
      message: "is required",
      admin: "required",
      label: "Password*",
    },
    length: {
      minimum: 8,
      message: "must be at least 8 characters",
      maximum: 20,
    },
    format: {
      pattern: /^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[!|@|#|\$|%|\^|&|\*])(?=.{8,20})/,
    }
  },

Answer 1

用

/^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[!@#$%^&*]).{8,20}$/
