我正在研究从 1 到 2 升级教程(Angular 1 upgrade)和 phonecat 代码库示例的 angularjs。在安装 typescript 和所有提到的依赖项后,为函数参数输入添加类型:boolean会使 chrome 执行失败,并出现“Uncaught SyntaxError: Unexpected token :” checkmarkFilterProvider 连续未创建,并且 Provider 注入组件失败。

(function() {
    ///<reference path='../../../typings/index.d.ts' />
    'use strict';

    angular.
        module('core').
        filter('checkmark', function() {
            return function(input:boolean) {
                return input ? '\u2713' : '\u2718';
            };
        });
})();

npm run tsc -w 命令编译 .ts 文件并创建地图,但是,浏览器执行失败。 在此处输入图像描述

最后 *.ts 源文件在项目资源管理器中编译,但浏览器没有它们,正如@tadwork 指出的那样。我的配置遗漏了什么?

更新

要运行 Angular 应用程序,我从 package.json 执行 npm start 脚本,理论上应该编译 *.ts 文件并以 ./app 作为服务器源运行 http-server(请参阅 package.json 脚本 -> 开始)。

脚本执行后的 ./app 文件夹已编译 *.js 和 *.map.js 文件。 在此处输入图像描述

看起来 Typescript 类型注释在没有被编译的情况下被注入浏览器,所以类型仍然在input参数上

return function(input: 布尔值 )
