奇怪的String.split（“\ n”）行为 [英] Strange String.split("\n") behavior

问题描述

我有一个.txt文本文件，包含一些行..
我使用RequestBuilder对象加载包含，并使用
words = String.split（\ n）拆分responseText ;但我想知道，为什么结果包含\ n部分..
例如，我的文字：

I have a .txt text file, containing some lines.. I load the contain using the RequestBuilder object, and split the responseText with words = String.split("\n"); but i wonder, why the result is contains the "\n" part.. For example, my text:

abc
def
ghi

结果是，

words[0] = "abc\n"
words[1] = "def\n"
words[2] = "ghi\n"

任何帮助都非常感谢。在此先感谢。

Any help is highly appreciated. Thanks in advance.

推荐答案

Windows回车（\\\\ n）不应该对结果产生明显的影响，也不需要转义传递给 String.split（）的正则表达式。

Windows carriage returns ("\r\n") shouldn't make a visible difference to your results, nor should you need to escape the regular expression you pass to String.split().

以下是使用 str.split（\ n）的上述证据： http://ideone.com/4PnZi

Here's proof of both the above using str.split("\n"): http://ideone.com/4PnZi

如果你做虽然有Windows回车，你应该（尽管严格来说没有必要）使用 str.split（\\\\ n）： http://ideone.com/XcF3C

If you do have Windows carriage returns though, you should (although strictly not necessary) use str.split("\r\n"): http://ideone.com/XcF3C
