JavaScript字符串编码/解码

Question

I have some strings like s0 = "\\"first line,\\\\nsecond line,\\\\n\\"" , and some other strings like s1 = "first line,\\nsecond line,\\n" , where s0 is like the string representation of the whole s1 . I wonder if there's any easy way to convert s0 and s1 both way. I understand I could do replace. However, there might be a whole lot of other escape sequences to take care of.

You could use JSON methods:

 s0 = "\\"first line,\\\\nsecond line,\\\\n\\"", s1 = "first line,\\nsecond line,\\n" console.log('Parse s0 ::', JSON.parse(s0)) console.log('Stringify s1 ::', JSON.stringify(s1))
