如何在TypeScript中处理内置对象的专有/自定义属性的警告

Question

我正在使用依赖于专有财产的navigator.id人物角色.由于此属性不是标准属性,因此TypeScript编译器会生成以下警告:

$ tsc home.ts --out my_ts_generated_code.js
/Users/..../home.ts(27,18): The property 'id' does not exist on value of type 'Navigator'

但.js文件已成功生成并在FF15浏览器上运行,没有任何警告/错误消息.
我还navigator.id按照文档的说明包含了一个polyfill ,因此navigator.id肯定会在每个浏览器中提供.

有人可以建议我如何处理这个警告吗？

的index.html

<!-- some HTML omit above -->
<script src="https://login.persona.org/include.js"></script>
<script src="my_ts_generated_code.js"></script>
<button class="btn" id="signin">Sign in</button>
<button class="btn" id="signout">Sign out</button>
<!-- some HTML omit below -->

home.ts

declare var $;

class Student {
    fullname : string;
    constructor(public firstname, public middleinitial, public lastname) {
        this.fullname = firstname + " " + middleinitial + " " + lastname;
    }
}

interface Person {
    firstname: string;
    lastname: string;
}

function greeter(person : Person) {
    return "Hello, " + person.firstname + " " + person.lastname;
}

var user = new Student("Jane", "M.", "User");

$(function() {
    $('#signin').on('click', function(e) {
        e.preventDefault();
        navigator.id.request();
    });

    $('#signout').on('click', function(e) {
        e.preventDefault();
        navigator.id.logout();
    });
    //document.body.innerHTML = greeter(user);
});

Answer 1

1)您可以重新解释导航器道具.

(<any>navigator).id.request();

2)你可以自己申报身份证明

mycompany.lib.d.ts

interface Navigator {
  id: any
}

app.ts

navigator.id.request();
