How to check file upload type in Angular JS?

Question

I am using the Angular File Uploader library in Angular JS. Here is filtersone that allows you to set file types for download. I do it like:

uploader.filters.push({
    name: 'imageFilter',
    fn: function (item /*{File|FileLikeObject}*/, options) {
    var type = '|' + item.type.slice(item.type.lastIndexOf('/') + 1) + '|';
         return '|doc|txt|docx|xml|pdf|djvu'.indexOf(type) !== -1;
   }
});

The problem is that the user can change the extension file, for example, change *.exeto *.pdf, and after Angular, the loader will add the file to the download queue.

And how can I show the information in the template where the PDF and txt files are?
