I got a string from “text\_area\_tag”. Because the browser working on windows while my rails server working on linux, there is ^M at the end of each line. What I want to do is to remove this character and separate the string to an array. How can I do this? thanks. ---

You have a string with embedded ^M characters and you wish to turn this into an array of strings? If that is correct then I would suggest looking at String#split. Colin ---

Thanks. I think split is what I want. Another thing is that how I can remove the ^M from a string. I found that there is a method “replace” in string class. But it will replace the whole string, right? ---
