AngularJS 在同一个界面启动多个ng-app应用模块详解

时间:2020-05-15 人气:0

AngularJS默认在一个html界面中只启动一个

ng-app 模块，而且是界面中第一次出现的那个使用 ng-app 声明的模块，该问题可以通过查看AngularJS源代码或者是文档验证。

解决方案：

直接上代码，如果有兴趣了解其中缘由，可以选择阅读后面的部分；

 <div id="test-0" ng-controller="testCtrl_0">

 var myApp_0 = angular.module("myApp-0", []);
 myApp_0.controller('nameCtrl', function ($scope, $rootScope){
 $scope.names = ["shen", "amy", "sereno"];
 $scope.age = 24;
 $rootScope.demo = "demo";
 });

 var myApp_1 = angular.module("myApp-1", []);
 myApp_1.controller('nameCtrl-1', function ($scope, $rootScope){
 $scope.names = ["shen-1", "amy-1", "sereno-1"];
 $rootScope.age = 24;
 });


 // 并行启动多个 ng-app
 var myApp1mod = angular.module('test-0',[]);
 myApp1mod.controller('testCtrl_0',function($scope){
 var content= {};
 content.message = "Hello Test-0";
 $scope.content= content;
 });

 var myApp2mod = angular.module('test-1',[]);
 myApp2mod.controller('testCtrl_1',function($scope){
 var content= {};
 content.message = "Hello Test-1";
 $scope.content= content;
 });

 angular.element(document).ready(
  function (){
  angular.bootstrap(document.getElementById("test-0"), ["test-0"]);
  angular.bootstrap(document.getElementById("test-1"), ["test-1"]);
  }
 );

</script>
