.factory工厂, $provider, service等等都是一样样的, 不要感觉很难, 其实就是看出一个数据模型或者实例就好了;:

复制代码 代码如下:

http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
http://www.w3.org/1999/xhtml">


angular
　　
   


   
   

       

            angular中的factory就相当于一个公用的实例方法,可以理解为一个多个控制器都可以用的函数;
       

       

            {{json}}
            <script><br>                 app.factory("ff", function() {<br>                     return {<br>                         "noting" : "json"<br>                     };<br>                 });<br>                 app.controller("factory", function($scope, ff) {<br>                     $scope.json = ff;<br>                 });<br>             </script>
       

   

   

       

            angular的指令;
       

         

                 Inhalten Sie für?
                                                                                                                        app.directive("heh", function() {
                       zurück {
                          einschränken: „AE“,
Ersetzen: true,
transclude: wahr,
Vorlage: '
'
                    };
                 })
                                                                                                                                                                                           





Verwenden der .ng-switch-Direktive (diese ist der Vorlage sehr ähnlich, es ist unsere übliche Winkelmethode zum Klicken, um das Tab-Plug-in anzuzeigen und auszublenden)::

ng-src和ng-href;

复制代码 代码如下:

angular
　　
   


   
   

       

            ng-src和ng-href的使用(如果使用src或者href的话,HTML初始化的时候就会加载,肯定是不行的)
       

       

           
               
           
       

       
   



如何操作页面的样式,这个直接改绑定的数据模型就好了:

复制代码 代码如下:

   

       

            angular对样式进行操作;(jQ是手动选择元素对元素样式进行操作,angular提供了一种更屌的方法,把元素的属性赋值给一个变量,你只要改变这个变量即可)
       

       

           
                hehe--o(^▽^)o哇;
           
       

       


   
   

       

            使用模板
       

       

                       
           
                           
           

           

               
           

       

         


   
   

       

            updateangular的通知数据更新三种方式$scope.$digest(),$scope.$apply(),以及通过$scope.$watch监听进行更新;
       

       

            {{hehe}}
           
           

                the value set by $scope.$watch ==>> {{wat}}

  • angular.uppercase

    •                                                                                                                                      

    Diese Tools und Methoden ähneln anderen Bibliotheken;
                     angle.element ist eine kleine JQ für anguarLite zur Auswahl von Elementen;
                                                                                              Angular.module ist eine Methode des Modulelements;

                  {{text}}
               

           

           



              

    NGPaste und ngmouseup und ngkeyup, ngmodeloptions ....... Als Referenz zur offiziellen Verwendung schauen Sie sich einfach die API an (der Beamte möchte FQ;)
