比較 string

[tjeff]

請教一下, 如果我有一個 string "an apple", 我要將此string 輸出至 indicator, 如何獲知我輸入的 string 與 "an apple" 符合? 如符合, 輸出 "an apple" 至 indicator, 如不符合, 呈現 error message " not matched", 請問我該如何建立? 非常感謝各位的回答

case if true 後面如果不用boolean, 而需要以string 呈現, 該如何修改? case if failed, 該如何用 one button dialog 來呈現error message? 非常感謝

hi,

Sorry if I am not quite understand your question/ problems 😉

The Case if Error (Failed) is already a One Button Dialog. And, for Case if No Error (Passed), it is up to you how you want to process with the Input String, isn't it?
