javascript-用TypeScript类编写Angular指令
作者:互联网
我可能只是试图一次组合太多“新手入门”概念,但是我试图使用TypeScript类编写自定义Angular指令.目前,我并没有做任何非常有用的事情,只是POC.
我有一个看起来像这样的TypeScript文件:
module App {
'use strict';
export class appStepper {
public link:(scope:angular.IScope, element: angular.IAugmentedJQuery, attrs: angular.IAttributes) => void;
public template:string = '<div>0</div><button>-</button><button>+</button>';
public scope = {};
public restrict:string = 'EA';
constructor(){ }
public static Factory(){
var directive = () =>
{ return new appStepper(); };
return directive;
}
}
angular.module('app').directive('appStepper', App.appStepper.Factory());
}
它在JavaScript中编译为:
(function(App) {
'use strict';
var appStepper = (function() {
function appStepper() {
this.template = '<div>0</div><button>-</button><button>+</button>';
this.scope = {};
this.restrict = 'EA';
}
appStepper.Factory = function() {
var directive = function() {
return new appStepper();
};
return directive;
};
return appStepper;
})();
App.appStepper = appStepper;
angular.module('app').directive('appStepper', App.appStepper.Factory());
})(App || (App = {}));
我的角度模块看起来像(我什至不知道是否需要这样做):
angular.module('app',['appStepper'])
我尝试在我看来使用它:
<div app-stepper></div>
并得到以下错误:
Uncaught Error: [$injector:nomod]
Uncaught Error: [$injector:modulerr]
为什么我的应用程序不知道我的指令?
解决方法:
尽管问题不完全相同,但此答案包含了我尝试执行的操作的示例:How can I define my controller using TypeScript?
我按照它引用的Plnkr中的示例进行操作,并发现成功:http://plnkr.co/edit/3XORgParE2v9d0OVg515?p=preview
我最后的TypeScript指令如下所示:
module App {
'use strict';
export class appStepper implements angular.IDirective {
public link:(scope:angular.IScope, element: angular.IAugmentedJQuery, attrs: angular.IAttributes) => void;
public template:string = '<div>0</div><button>-</button><button>+</button>';
public scope = {};
public restrict:string = 'EA';
constructor(){ }
}
angular.module('app').directive('appStepper', [() => new App.appStepper()]);
}
