A small utility to read ASP.NET issued cookies from javascript. (Cookies and sub-cookies)

cookieCutter.js

;(function(){
	function cookieCutter(cookieName, subCookieName) {
		var name = cookieName + "=";
		if (subCookieName) {
			name += subCookieName + "=";
		}

		var cookie = document.cookie + ";";
		var cookieValueStart = cookie.indexOf(name) + name.length;
		var val = cookie.substring(cookieValueStart, cookie.indexOf(";", cookieValueStart));
	
		return val.trim();
	};  
  // Publish the library as an AMD module, CommonJS Module, or to the global window object
  if (typeof define === 'function' && define.amd) {
    define('cookieCutter', function() {
      return cookieCutter;
    });
  } else if(typeof require === 'function' && typeof exports === 'object' && typeof module === 'object') {
    module.exports = cookieCutter;
  } else {
    window.cookieCutter = cookieCutter;
  }
})();

How to use

Without a module loader

<script src="cookieCutter.js"></script>
<script>
  var cookieName = '...';
  var subCookieName = '...';
  var res = cookieCutter(cookieName, subCookieName);
</script>

With AMD

require(["cookieCutter"], function(cookieCutter){
  var cookieName = '...';
  var subCookieName = '...';
  var res = cookieCutter(cookieName, subCookieName);
});

With CommonJS

var cookieCutter = require("cookieCutter");
var cookieName = '...';
var subCookieName = '...';
var res = cookieCutter(cookieName, subCookieName);
