ruby - 用空格分割字符串

Question

我想用空格序列分割一个字符串。

例如这个字符串："\tFirst \t\tSecond Third \t"应该是这样的数组：['First', 'Second', 'Third']

不幸的是@array = str.split(' ')，或者str.split('\t')在这种情况下不起作用。

什么都不做，就分开。空白是默认的！

p "\tFirst \t\tSecond Third \t".split # => ["First", "Second", "Third"]

String#split可以接受正则表达式（文档）

s = "\tFirst \t\tSecond Third \t"

s.split(/\s/).reject(&:empty?) # => ["First", "Second", "Third"]

试试这个

@array = str.split(/\s/)

您也可以使用String#scan.

"\tFirst \t\tSecond Third \t".scan(/\w+/) # => ["First", "Second", "Third"]
