I have an Angular2 click event defined in the template, inside the table's cell:
我在模板中定义了一个 Angular2 单击事件，位于表格的单元格内：
<td (click)="click2Download()">fileName.txt</td>
In the typescript component, I need help to define a method click2Download()that would automatically start downloading the fileName.txt to client's browser. Note: file is on the same domain, e.g.:
在打字稿组件中，我需要帮助定义一个方法click2Download()，该方法将自动开始将 fileName.txt 下载到客户端的浏览器。注意：文件在同一个域中，例如：
http://example.com/fileName.txt

Have you tried: window.location.href = '...';?
你有没有试过：window.location.href = '...';？
To force download of files you should use html attribute: <a target="_self" href="somefile.txt" download="somefile.txt">
要强制下载文件，您应该使用 html 属性： <a target="_self" href="somefile.txt" download="somefile.txt">
