[英]How to pass array to sub or gsub in ruby?
I have an array of characters I want to be removed from a string: 我有一个字符数组,我想从字符串中删除:
stops = ["[", "]", "^", "(", ")", "#", "*", "?", "~"]
I want to be able to pass the array and have all occurrences of those chars removed so that: 我希望能够传递数组并删除所有出现的chars,以便:
"str [with] unwanted# char*acters"
becomes 变
"str with unwanted characters"
"str [with] unwanted# char*acters".gsub(Regexp.union(stops), '')
# => "str with unwanted characters"
如果您需要删除字符,可以使用#delete
str.delete "[]^()#*?~"
str.tr('[]^()#*?~','')
str.tr('[]^()#*?~','abcdefghi')
