对于我的应用程序使用的各种视图使用单独的样式表,正确的方式是什么?

目前,我在顶部的view / partial的html中放置了一个链接元素,但是这不是好做法。

另一种可能是将独立的样式表放在我的index.html中,但是我希望h只在样式表的视图以性能名称加载时才加载样式表。

1.创建一个自定义为<head>要素:

app.directive('head', ['$rootScope','$compile',
    function($rootScope, $compile){
        return {
            restrict: 'E',
            link: function(scope, elem){
                var html = '<link rel="stylesheet" ng-repeat="(routeCtrl, cssUrl) in routeStyles" ng-href="{{cssUrl}}" />';
                elem.append($compile(html)(scope));
                scope.routeStyles = {};
                $rootScope.$on('$routeChangeStart', function (e, next, current) {
                    if(current && current.$$route && current.$$route.css){
                        if(!angular.isArray(current.$$route.css)){
                            current.$$route.css = [current.$$route.css];
                        }
                        angular.forEach(current.$$route.css, function(sheet){
                            delete scope.routeStyles[sheet];
                        });
                    }
                    if(next && next.$$route && next.$$route.css){
                        if(!angular.isArray(next.$$route.css)){
                            next.$$route.css = [next.$$route.css];
                        }
                        angular.forEach(next.$$route.css, function(sheet){
                            scope.routeStyles[sheet] = sheet;
                        });
                    }
                });
            }
        };
    }
]);

2。指定哪些样式表属于哪些路由,使用$routeProvider

app.config(['$routeProvider', function($routeProvider){
    $routeProvider
        .when('/some/route/1', {
            templateUrl: 'partials/partial1.html', 
            controller: 'Partial1Ctrl',
            css: 'css/partial1.css'
        })
        .when('/some/route/2', {
            templateUrl: 'partials/partial2.html',
            controller: 'Partial2Ctrl'
        })
        .when('/some/route/3', {
            templateUrl: 'partials/partial3.html',
            controller: 'Partial3Ctrl',
            css: ['css/partial3_1.css','css/partial3_2.css']
        })
}]);

这里有些例子:

  $routeProvider
    .when('/page1', {
      templateUrl: 'page1/page1.html',
      controller: 'page1Ctrl',
      /* Now you can bind css to routes */
      css: 'page1/page1.css'
    })
    .when('/page2', {
      templateUrl: 'page2/page2.html',
      controller: 'page2Ctrl',
      /* You can also enable features like bust cache, persist and preload */
      css: {
        href: 'page2/page2.css',
        bustCache: true
      }
    })
    .when('/page3', {
      templateUrl: 'page3/page3.html',
      controller: 'page3Ctrl',
      /* This is how you can include multiple stylesheets */
      css: ['page3/page3.css','page3/page3-2.css']
    })
    .when('/page4', {
      templateUrl: 'page4/page4.html',
      controller: 'page4Ctrl',
      css: [
        {
          href: 'page4/page4.css',
          persist: true
        }, {
          href: 'page4/page4.mobile.css',
          /* Media Query support via window.matchMedia API
           * This will only add the stylesheet if the breakpoint matches */
          media: 'screen and (max-width : 768px)'
        }, {
          href: 'page4/page4.print.css',
          media: 'print'
        }
      ]
    });

指令

myApp.directive('myDirective', function () {
  return {
    restrict: 'E',
    templateUrl: 'my-directive/my-directive.html',
    css: 'my-directive/my-directive.css'
  }
});

另外:

myApp.controller('pageCtrl', function ($scope, $css) {

  // Binds stylesheet(s) to scope create/destroy events (recommended over add/remove)
  $css.bind({ 
    href: 'my-page/my-page.css'
  }, $scope);

  // Simply add stylesheet(s)
  $css.add('my-page/my-page.css');

  // Simply remove stylesheet(s)
  $css.remove(['my-page/my-page.css','my-page/my-page2.css']);

  // Remove all stylesheets
  $css.removeAll();

});
