I am in the middle of developing a web app. I am using AngularJS for loading all the files dynamically into the UI.

I have an index.html file into which

Answer 1

I used jquery to do the hardwork like this

/** resolve will come inside your route .when() function **/
resolve: {
        theme: function ($route, $q) {
            changeCss($route, $q);
        }
    }

/** This will come just outside your route .when() function, make sure the following function shall be in scope of the route provider **/
    var changeCss = function ($route, $q) {
        var defer = $q.defer();
        // Change the CSS as per the param received
        if ($route.current.params.css != undefined) {
            if ($route.current.params.css === ‘dark’) {
                loadCSS(“assets / css / dark.css”);
                defer.resolve();
            }
            if ($route.current.params.css === ‘light’) {
                loadCSS(“assets / css / light.css”);
                defer.resolve();
            } else {
                defer.resolve();
            }
        }
        return defer.promise;
    }
    var loadCSS = function (href) {
        var cssLink = $(“ < link rel = ’stylesheet’ type = ’text / css’ href = ’”+href + “‘ > ”);
        $(“head”).append(cssLink);
    };

I have used Promise because this will make sure to load the css before it shows/load the angularjs route/page.
