Question

我想创建一个自定义过滤器在angularjs中使用typescript 我的代码

//Reverse.ts
class Reverse{
    static filter(msg:string) {
        return (msg) => {
            return msg.split("").reverse().join("");
        }
    }
}


//app.ts
/// <reference path="../lib/angular.d.ts"/>
/// <reference path="./Reverse.ts"/>
class MyApp{
    public app:AngularModule;
    constructor(){
          this.app = angular.module('myApp', []);
          this.app.filter ('reverse',(msg) => { return Reverse.filter(msg) });
    }
}
class AlbumController {
    constructor (private $scope) {
        this.$scope.test = '20 whatsomething';
     }
}


new MyApp();

//index.html
<!DOCTYPE html>
<html>
    <head>
        <title>My test TS</title>
    </head>
    <body>
    <div data-ng-app="myApp">
        <div data-ng-controller="AlbumController">  
            {{test | reverse}}
        </div>
    </div>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
    <script src="./Reverse.js"></script>
    <script src="./app.js"></script>
    </body>
</html>

我收到错误：未知提供者：msgProvider＆lt; - msg＆lt; - reverseFilter 所以，你能帮助我吗？

更新

我解决了

class MyApp{
    public app:AngularModule;
    constructor(){
          this.app = angular.module('myApp', []);
          this.app.filter ('reverse',() => { 
            return (msg) => {
                return Reverse.filter(msg);
            } 
          });
    }
}
class AlbumController {
    constructor (private $scope) {
        this.$scope.test = '20 whatsomething';
     }
}


new MyApp();


class Reverse{
    static filter(msg:string) {
        return msg.split("").reverse().join("");
    }
}

如果您使用--out编译器标志编译，原始代码将起作用：

tsc --out app.js app.ts
