How does one do a simple string search in js?

I want to get a simple true/false answer with if string1 is inside string2 at any position in the string.

If string1 is a literal, you can do this:
(string2.search(/string1/)==-1)

Otherwise...
(string2.search(new RegExp(string1))==-1)

Ok, so it is a literal, and if string2 is part of an object, the same applies right?

I should be able to do...

if(ojb.string2.search(/string1/)==-1

That would be if string1 is NOT found right?

What are the //'s for? Are they saying that string1 is literal?

As long as it can be coerced into a string, yes.

It's a shorthand method of expressing a regexp.
