Ruby中的数组迭代

所以我动态创建了这个数组：

array = [ "Name can't be blank", "Email can't be blank",
      "Email is invalid", "Password can't be blank",
      "Password is too short (minimum is 6 characters)",
      "Password confirmation can't be blank" ]

我想要的是迭代这个数组，如果有值：

"Password can't be blank"

"Password confirmation can't be blank"

验证是否存在以下值：

"Password can't be blank"

"Password confirmation can't be blank"

然后扔掉它

因此，返回的数组将是：

    array = [ "Name can't be blank", "Email can't be blank",
      "Email is invalid", "Password can't be blank",
      "Password is too short (minimum is 6 characters)"]

非常感谢

这就是你能做到的<代码>包括？检查

“密码不能为空”

<代码>删除删除项目

if array.include? "Password can't be blank"
  array.delete "Password confirmation can't be blank"
end

为什么要麻烦？如果密码为空，我希望您删除“太短”警告。您只需将其写入：

array。如果array.include？（“密码不能为空”）则删除（“密码确认不能为空”）
