Question

I have a string of "aa$bb$cc"; and I want to replace it to be "aa\$bb\$cc"
I’ve tried this:

var str = "aa$bb$cc"
str.replace(/$/g, "\\$"); 

But the outpus is "aa$bb$cc\$"

How can I replace it and get same (correct…) result in all browsers?

Answer 1

str = str.replace(/\$/g, "\\$");

$ in a regular expression means “end of the line”. Therefore, it’s replacing all the ends of lines with \$. Escape the $ in the regular expression and it works.
