How to parse regular expression text using Json

Question

I have this line that I want to convert to a JSON object, the problem is that one of the fields of the object is a regular expression:

"{
     \"regex\": /^([a-zA-Z0-9_\\.\\-\\+%])+\\@(([a-zA-Z0-9\\-])+\\.)+([a-zA-Z0-9]{2,4})+$/,
     \"alertText\": \"test\"
}"

Is there a way to get a JavaScript object without making hundreds of replacements?

EDIT: am I using the following code to store the correct serialized version of the source object from a regex string? :

RegExp.prototype.toJSON = function() { return this.source; };

Then I could change the contents of the line:

{"regex":"^([a-zA-Z0-9_\\.\\-\\+%])+\\@(([a-zA-Z0-9\\-])+\\.)+([a-zA-Z0-9]{2,4})+$","alertText":"* {{alertText}}"}

Therefore, I can use it as a template, and then, when necessary, a JSON.parse string to get a new object.
