在以下示例中,有三个模块,第二个模块需要第一个模块。这在使用ng-appin引用时有效div。但是名为 的第三个模块someonesApp不起作用。当使用 ng-app 引用第二个模块时,它的 run 方法不会运行。没有前两个模块第三个有效,为什么会这样?

<!DOCTYPE html>
<html >
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular.min.js"></script>


</head>
<body ng-init="name='123'">

<div ng-app="myApp">
</div>

<div ng-app="someonesApp">
</div>



<script>

var yourApp = angular.module('yourApp',[]);
yourApp.run(function(){
    console.log('run block of yourApp');
});


var myApp = angular.module('myApp',['yourApp']);

myApp.run(function(){
    console.log('run block of myApp');
});


var someonesApp = angular.module('someonesApp',[]);

someonesApp.run(function(){
    console.log('run block of someonesApp');
});



</script>

</body>    
</html>

这是修改后的代码,在这种情况下,我删除了<div ng-app="myApp"></div>第三个模块。

<!DOCTYPE html>
<html >
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular.min.js"></script>


</head>
<body ng-init="name='123'">

<div ng-app="someonesApp">
</div>



<script>

var yourApp = angular.module('yourApp',[]);
yourApp.run(function(){
    console.log('run block of yourApp');
});


var myApp = angular.module('myApp',['yourApp']);

myApp.run(function(){
    console.log('run block of myApp');
});


var someonesApp = angular.module('someonesApp',[]);

someonesApp.run(function(){
    console.log('run block of someonesApp');
});



</script>

</body>    
</html>
