how to use replace in javascript for special characters

Question

I want to make this:

[:fr]french[:de]german[:en]english[:]

Look like this:

<!--:fr-->french<!--:de-->german<!--:en-->english<!--:-->

I have tried:

string.replace("[:", "<!--:");

and

string.replace("]", "-->");

but no luck,

Any help would be appreciated!

您可以：

str = str.replace(/\[(:[a-z]*)\]/g, "<!--$1-->");
