I have as string as "pas" and "with_pas". I want to replace it with blank string. Now I am doing as follows
string.gsub("pas","").gsub("with_pas","")
In some scenario i get the string as "pas" and in some other with "with_pas".
Is there a better way to do this?
您可以使用当前的方法,但是需要更改顺序,否则将无法按预期工作:
string.gsub("with_pas","").gsub("pas","")
那使用正则表达式呢?
string.gsub(/(with_)?pas/, "")
str.gsub(/pas|with_pas/, '').squeeze
这将删除单词,并且squeeze
将删除gsub
添加的额外空间。
