Question

我是ruby的新手。我有一个像

这样的字符串

string = "You have successfully placed Service Request No. \#{@service_requests.id} for \#{@service_requests.category.name} . Our representative will be in touch with you soon for the same. Thank you."

我想删除＆＃34; \＆＃34;从整个字符串。

output_string = "You have successfully placed Service Request No. #{@service_requests.id} for #{@service_requests.category.name} . Our representative will be in touch with you soon for the same. Thank you."

如何使它成为可能。

Answer 1

试试这个：

string.gsub(/\\/, '') # or string.gsub!(/\\/, '') for inplace substitution

Answer 2

>> string = "You have successfully placed Service Request No. \#{@service_requests.id} for \#{@service_requests.category.name} . Our representative will be in touch with you soon for
the same. Thank you."
>> puts(string)
=> You have successfully placed Service Request No. #{@service_requests.id} for #{@service_requests.category.name} . Our representative will be in touch with you soon for the same. Thank you.
>> puts(string.inspect)
=> "You have successfully placed Service Request No. \#{@service_requests.id} for \#{@service_requests.category.name} . Our representative will be in touch with you soon for the same. Thank you."

确保您知道字符串表示（puts string.inspect）和字符串内容（puts string）之间的区别，并注意反斜杠作为表示的工件。

Answer 3

您可以将其删除，如：

string.gsub(%r{\"}, '')
