如何將數組傳遞給sub或gsub紅寶石？

Question

我有我想從一個字符串刪除的字符數組：

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

我希望能夠通過該陣列，並有去除，使得這些字符的所有實例：

"str [with] unwanted# char*acters"

成爲

"str with unwanted characters"

Answer 1

如果您需要刪除字符，你可以使用#delete

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

Answer 2

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

Answer 3

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