What is the best way to generate an object with a text string that is quote-free?

When passing an object to the MongoClient collection.find() method, I'm facing an issue where I don't want quotes around the values. If I pass a literal, it works fine:

cursor = collection.find({EmployeeName: {'$regex': /Jo/i}});

However, if I try to construct the object like this:

var queryt = "/Jo/i";
var queryo = {
    EmployeeName: {'$regex': queryt}
};

It doesn't work. When I check console.log(queryo), I notice that there are quotes present around "Jo/i":

{ EmployeeName: { '$regex': '/Jo/i' } }

In my application, 'queryt' is derived by extracting values from the 'query' object returned from an 'get' function in Express. For example, I make a call with an URL ending as "?EmployeeName:/Jo/i". In my "get" function, I do:

var queryt=req.query.EmployeeName;

Essentially, I am using this node.js app as a backend server that accepts queries via HTTP get requests.

I have tried different methods to remove the quotes but without success.

Apologies if this seems like a beginner question, I am new to this and have spent hours trying to resolve it. Hopefully, a more experienced node.js developer can guide me on how to structure this object so that collection.find will accept it. Thank you!

Answer №1

Remove double quotes in var queryt = "/Jo/i"; to create a string.

Instead, use var queryt = /Jo/i; to create a regular expression.

Update: kcantrel discovered the solution. The previous method mentioned will not work for him. He found success with the following method:

queryt = RegExp("jo", "i")
