javascript match() without slash

Question

I found this code:

var k= 'test';

var m = document.cookie.match(k+'=([^;]*)');

and I'm trying to get which cookies will be read. Normally there is a leading slash in the regex like: x.match (/\d+/g); but not here, so my question is how has the cookie to look like?

See the documentation on MDN:

If regexp is a non-RegExp object, it is implicitly converted to a RegExp by using new RegExp(regexp).

do you have any example how the cookie look like?

@hamburger it would match that regex. So test= followed by any amount of non-; characters.

thats means the regex ist between the brackest [^;]* and the cookiename must contain an equal signe?

@hamburger — No. The whole string will be converted to a regular expression.

so the cookiename has to look like this: test=(hello)
