Question

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"

验证是否有值：

"Password confirmation can't be blank"

并摆脱它。

所以返回的数组将是：

    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！

这就是你能够做到的。 include?检查"Password can't be blank"。 delete删除该项目。

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

Ruby中的数组迭代
