只允许angular-file-upload模块中的特定文件扩展名可单击 [英] Only allow specific file extensions in angular-file-upload module to be clickable

问题描述

我正在使用此模块， https://github.com/nervgh/angular-file -upload

我正在使用他们的简单例子， http://nervgh.github.io/pages/angular-file-upload/examples/simple/

I am using their simple example, http://nervgh.github.io/pages/angular-file-upload/examples/simple/

当您单击选择文件按钮时，它将打开一个窗口，允许我们选择要上传的文件。我想要发生的是只允许点击特定的文件扩展名。是否有未记录的配置可以做到这一点？

When you click "Choose file" button, it will open a window which allows us to pick a file that we want to upload. What I would like to happen is to only allow specific file extensions to be clicked. Is there a non-documented configuration which will do that?

例如，在配置中，我们只允许.txt扩展名，当我点击选择文件按钮时，它会打开一个窗口并显示所有文件。但是，没有扩展名.txt的文件将被禁用。

For example, in the config, we only allowed .txt extensions, when I click "Choose file" button, it will open up a window and show all the files. However, files that doesn't have the extension .txt will be disabled.

出于安全考虑，我不这样做。我只是按照提供的设计/说明进行操作。 :)我总是可以使用mitm工具拦截并允许上传其他扩展。

I'm not doing this for security purposes. I am just following the design/instructions provided to me. :) I can always use mitm tools to intercept and allow other extensions to be uploaded.
