如何制作有效的多行Javascript REGEX

Question

I have a block of text that can literally be anything. Somewhere in the text is something like [block] or [header]. I want to match against the following regex:

new RegExp("(.*)\\\\[" + config.wrapper+ "\\\\](.*)", "m");

If I write "hello[block]" it works perfect.

If I write "hello

[block]" it catches nothing.

What am I missing to properly match?

Note, for complicated reasons, I can't currently use a template engine like handlebars or any of those in this special case.

Change this:

(.*)

to this:

([\\s\\S]*)

because the . doesn't match line breaks.
