How to escape a quote in a string?

[Jane Doe]

Hi,

I've tried different things, but still can't find how to escape a
single quote in a string:

mystring = '\'stuff\''
var input = new RegExp(mystring,"gi");

ie. how to copy 'stuff' including its native single quotes into the
mystring regex?

Thank you
JD.

mystring = '\'stuff\''

That looks correct. Put a "var" in front and a ";" behind, and I can't
find anything to complain about (and those shouldn't change anything
in this exampel).

You could just write
var mystring = "'stuff'";

var input = new RegExp(mystring,"gi");

Let me try:
var mystring = '\'stuff\'';
var re = RegExp(mystring,"gi");
if (re.test("asgasgag'stuff'asfasf")) { alert ("ok");}
if (re.test("asgasgagstuffasfasf")) { alert ("bad");}

This only alerts "ok".

ie. how to copy 'stuff' including its native single quotes into the
mystring regex?

The way you do it looks fine to me.

What you have there should work fine:

var mystring = '\'stuff\'';
var re = new RegExp(mystring, "gi");
alert("'stuff'".replace(mystring, "'newstuff'"));

alerts 'newstuff' in IE6SP1, Netscape 4 and Mozilla.
