RegExp - Build Dynamic Pattern

I have written an ASP.net app that pulls settings from a
database. Part of the setting definition is a regular expression that
I want to use on the client via JavaScript for data validation...


1) Sample code for the setting object:
----------------------------------------------------
function setting(id, name, validationPattern, validationMsg) {
this.id = id;
this.name = name;
this.validationPattern = validationPattern;
this.validationMsg = validationMsg;
}


2) Sample code on the page that creates a new setting object:
----------------------------------------------------
setting(1, 'test', '^d{1,1}$|^d{2,2}$|^100$', 'invalid value');


3) The issue:
----------------------------------------------------
The setting object gets built just fine except the pattern argument
gets escaped by javascript!!!

^d{1,1}$|^d{2,2}$|^100$

GETS ESCAPED TO

^d{1,1}$|^d{2,2}$|^100$ (Notice how the double is now a single )


Is there any way for me to preserve the pattern text as is?
