陣列迭代

-3

所以我有這個數組動態創建：陣列迭代

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" ]

什麼，我想通過這個數組迭代，如果有值：

"Password can't be blank"

驗證是否存在價值：

"Password confirmation can't be blank"

並擺脫它。

所以返回的數組將是：

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)"]

非常感謝！

爲什麼要麻煩？如果密碼爲空白，我寧願刪除「太短」警告。 –

你剛剛寫到：'array.delete（「密碼確認不能爲空」）如果array.include？（「密碼不能爲空」）' – user2422869

「詢問代碼的問題必須證明對問題得到解決包括嘗試解決方案，爲什麼他們不工作，以及預期的結果。另請參見：[堆棧溢出問題清單]（http://meta.stackexchange.com/questions/156810/stack-overflow-question-清單）」 –

這就是你如何做到的。 include?檢查"Password can't be blank"。 delete刪除該項目。

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