在这个AngularJS代码中：
<!DOCTYPE html>
<html>
<head>
<script src="http://code.angularjs.org/1.2.9/angular.min.js" type="text/javascript"></script>
<script>
var app1 = angular.module('app1',[]);
app1.controller('Ctrl1',function ($scope)
{
$scope.name = "Jack";
});
var app2 = angular.module('app2',[]);
app2.controller('Ctrl2',function ($scope)
{
$scope.name = "Steve";
});
</script>
<title>Test Controllers</title>
</head>
<body>
<div ng-app="app1">
<div ng-controller="Ctrl1">
<span>{{name}}</span>
</div>
</div>
<div ng-app="app2">
<div ng-controller="Ctrl2">
<span>{{name}}</span>
</div>
</div>
</body>
</html>
我有两个ng-app和两个控制器.但只有第一个似乎有效.杰克的名字显示但史蒂夫没有.为什么？
显示问题的JSFiddle在这里：

ng-app指令的自动初始化仅发生一次,但您可以使用bootstrapping方法手动初始化其他模块. (见：https://docs.angularjs.org/guide/bootstrap)
