replace()

How do you use string.replace()? The concept seems simple enough, but I don't understand the $$4\'t\7 type stuff used in the arguements. Is it supposed to be a string? What does it represent and/or do? :confused:

Well to replace I think you can do something like this -

document.body.innerHTML=document.body.innerHTML.replace("1st String","2nd String");

those funky things is a regular expression, it is easy to understand once you know what it means.

JavaScript Kit has a tutorial on them:
