I'm looking into writing some jQuery extensions.

Example:

1. $.fn.IsTest = function () {
2.     let result = this.val() === "test";
3.     return result;
4. }

Usage:

1. $("select").IsTest();

So far I have written extensions for the input element and as you can see I use val() to get the value. but is it possible to write an extension for the value itself or a variable?

Ex:

1. $.fn.IsTest = function () {
2.     let result = this === "test";
3.     return result;
4. }

Usage like this:

Thanks!
