here is javascript custom validation

var files = document.getElementsByName("uploadfile");
if(files[0].value.indexOf(".txt") == -1) {
// Code placed here will be executed if an invalid file type is found.
}

And yes you can use accept attribute as well:

<input accept="audio/*|video/*|image/*|MIME_type" />

However as far as I know it is not supported by IE and Safari

But please make sure to validate the uploaded file on the server side as well. Just client validation is not enough.

Yes, you can use the accept attribute. Browser supports varies. It takes an Internet media type (MIME type) list as value. For plain text (which is that .txt files usually are), that would be accept="text/plain". This may or may not affect the file selection functionality by restricting the choices to files that the browser regards as plain text files.
