是否有可能让一个控制器使用另一个?
例如:
此HTML文档只是打印MessageCtrl控制器在messageCtrl.js文件中传递的消息.
<html xmlns:ng="http://angularjs.org/">
<head>
<meta charset="utf-8" />
<title>Inter Controller Communication</title>
</head>
<body>
<div ng:controller="MessageCtrl">
<p>{{message}}</p>
</div>
<!-- Angular Scripts -->
<script src="http://code.angularjs.org/angular-0.9.19.js" ng:autobind></script>
<script src="js/messageCtrl.js" type="text/javascript"></script>
</body>
</html>

控制器文件包含以下代码:
function MessageCtrl()
{
this.message = function() {
return "The current date is: " + new Date().toString();
};
}

这只是打印当前日期;
如果我要添加另一个控制器,DateCtrl它将日期以特定格式交还给MessageCtrl,那怎么会这样做呢?DI框架似乎关注XmlHttpRequests和访问服务.
我最近Object.create()在JavaScript中偶然发现了这个方法,并试图推断它与创建一个对象的新实例有什么不同new SomeFunction(),当你想要使用另一个时.
请考虑以下示例:
var test = {
val: 1,
func: function() {
return this.val;
}
};
var testA = Object.create(test);
testA.val = 2;
console.log(test.func()); // 1
console.log(testA.func()); // 2
console.log('other test');
var otherTest = function() {
this.val = 1;
this.func = function() {
return this.val;
};
};
var otherTestA = new otherTest();
var otherTestB = new otherTest();
otherTestB.val = 2;
console.log(otherTestA.val); // 1
console.log(otherTestB.val); // 2
console.log(otherTestA.func()); // 1
console.log(otherTestB.func()); // 2Run Code Online (Sandbox Code Playgroud)
请注意,在两种情况下都观察到相同的行为.在我看来,这两种情况之间的主要区别是:
Object.create()实际使用的对象实际上形成了新对象的原型,而在new …当我第一次启动我的网站时,我收到了这个错误

我正在使用DataContractJsonSerializer,它喜欢输出到Stream.我想要对串行器的输出进行顶部和尾部处理,因此我使用StreamWriter交替写入我需要的额外位.
var ser = new DataContractJsonSerializer(typeof (TValue));
using (var stream = new MemoryStream())
{
using (var sw = new StreamWriter(stream))
{
sw.Write("{");
foreach (var kvp in keysAndValues)
