如何將數組傳遞給ruby中的sub或gsub？

Question

我有一個字符數組，我想從字符串中刪除：

stops = ["[", "]", "^", "(", ")", "#", "*", "?", "~"]

我希望能夠傳遞數組並刪除所有出現的chars，以便：

"str [with] unwanted# char*acters"

變

"str with unwanted characters"

Answer 1

"str [with] unwanted# char*acters".gsub(Regexp.union(stops), '')
# => "str with unwanted characters"

Answer 2

如果您需要刪除字符，可以使用#delete

str.delete "[]^()#*?~"

Answer 3

str.tr('[]^()#*?~','')
str.tr('[]^()#*?~','abcdefghi')
