不要publishAs值必须在角飞镖独特之处？ [英] Do publishAs values have to be unique in Angular Dart?
问题描述
我怀疑这是一个错误，甚至可能 HTTPS的体现：// github上。 COM /角/ angular.dart /问题/ 396 。
I suspect this is a bug, possibly even a manifestation of https://github.com/angular/angular.dart/issues/396.
我要注册多个控制器，并希望使用 CTRL 作为内的 publishAt 字段的值 @NgDirective 。这导致了第二个 CTRL 重挫第一位的价值，即使它们在不同的范围存在。
I want to register multiple controllers and want to use ctrl as the value of the publishAt field within @NgDirective. This leads to the second ctrl clobbering the value of the first one, even though they exist in different scopes.
下面认为：
<!DOCTYPE html>
<html>
<body>
<div>
<div foo-controller>
<!-- PRINTS 'bar'. -->
<p>{{ctrl.item}}</p>
</div>
<div bar-controller>
<!-- PRINTS 'bar'. -->
<p>{{ctrl.item}}</p>
</div>
</div>
<script type="application/dart" src="main.dart"></script>
<script type="text/javascript" src="packages/browser/dart.js"></script>
</body>
</html>
这里是飞镖code：
And here is the Dart code:
import 'package:angular/angular.dart';
@NgDirective(
selector: '[foo-controller]',
publishAs: 'ctrl'
)
class FooController {
String item = 'foo';
}
@NgDirective(
selector: '[bar-controller]',
publishAs: 'ctrl'
)
class BarController {
String item = 'bar';
}
main() {
ngBootstrap(module: new Module()
..type(FooController)
..type(BarController));
}
输出为'巴'两次。如果我让 publishAs 值独特的，输出的是'富'后面'酒吧'。
The output is 'bar' both times. If I make the publishAs values unique, the output is 'foo' followed by 'bar'.
这是一个错误或我误解范围是如何工作的？
Is this a bug or am I misunderstanding how scopes work?
