Validate.js ReGex 未按预期工作

如何解决Validate.js ReGex 未按预期工作

我正在尝试使用格式：模式：Validate.js 的功能来确保密码满足至少一个大写、一个小写、一个数字和一个特殊字符的要求，并且具有最小长度8 个，最多 20 个。存在和长度功能如预期。有人有任何提示吗？

 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})/,}
  },

解决方法

使用

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