Find Checkbox by Value in NodeJS with JQuery

How can I find a checkbox in NodeJS with JQuery? I've tried the basic ways that I've found, but none seem to work. I've attached the code I'm using to run the command:

require("jsdom").env("http://ift.tt/2kPQwqS", function (err, window) {
    if (err) {
        console.error(err);
        return;
    }

   var $ = require("jquery")(window);
   $(window).ready(function () {

        if ($(":checkbox[value='IVC Library - Room 100E 8:00am - 8:30am Friday, February 10, 2017']").length > 0)
            console.log("Checkbox exists.");

    });
});

In this case, the value of the checkbox is from here: http://ift.tt/2kPQwqS. The checkbox is nested within a form.
