Is there a way to prevent some variables from being renamed via asp.net System.Web.Optimization

I'm using ASP.Net bundling and minification ( ) System.Web.Optimizationin an AngularJS project .

Everything works fine except for one case.

At this point, we must eval()express. We know this isn't ideal, although no other solution currently meets our needs.

So we have this line:

var isValid = eval('globalJson.Permissions.' + attrs.drHasPermissionFor);

Now this line fails because minification changes the names of our variables etc.globalJson

Is there a way to instruct ASP.Net Minification not to rename specific variables?

Starting from the answer given - we've used the Angulars safe way to inject.

The directive to use this directive looks like this:

    appDirectives.directive('drHasPermissionFor', ['globalJson', function (globalJson) {
        return {
            restrict: 'A',
            link: function (scope, element, attrs) {
                //code .....

                // how can I reference the injected globalJson here - so that i know it's using the
                // newly minified name..
                var isValid = eval('globalJson.Permissions.' + attrs.drHasPermissionFor);

//more code......
            }
        };
    }]);
