问题描述
在AngularJS中，有一个用于指令(和其他指令)的属性，用于指定是否可以通过元素名称或属性来实例化它，例如元素AND属性的restrict:EA.
In AngularJS there is an attribute for directives (and others) to specify if it can be instantiated by an element name or an attribute - like restrict:EA for element AND attribute.
文件 angular.dart/lib/指令/ng_a.dart 包含注释* @restrict E，该注释指示该指令用于<A> element.
The file angular.dart / lib / directive / ng_a.dart contains a comment * @restrict E which indicates the directive is for the <A> element.
在Angular.dart中是否不需要restrict?
什么是替代品?
Is restrict not necessary in Angular.dart?
What is the replacement?
推荐答案
正确的Angular.dart没有restrict，因此请忽略ng_a.dart中的注释，它可能只是JS版本的复制粘贴.所有指令/组件/控制器均使用selector，因此通常需要非常具体.如果需要等效的restrict:EA，则可以在类上应用两个注释.例如:
Correct, Angular.dart doesn't have restrict, so please disregard the comment in ng_a.dart, it's probably just a copy-paste from JS version. All directives/components/controllers use selector, so you normally need to be very specific. If you need an equivalent of restrict:EA, you could apply two annotations on the class. Ex:
@NgDirective(selector: 'foo')
@NgDirective(selector: '[foo]')
class FooDirective {
}
