This is the most easiest way of allowing users to download a file. But in some cases the web application may want to handle the download part itself, rather than leaving it to the browser.
It may have its own reasons like showing the download progress of the file in the applicaton's UI itself. Another reason may be monetization - the application can show an advertisement to the user while the file is being downloaded. This tutorial shows how to make an AJAX request to download a file, and showing the download percentage completed. However when downloading binary files, the responseType property of the request object is set to blob.
Possible values of responseType property are empty string default , arraybuffer , blob , document , json , and text. For simply downloading binary files use blob as the response type. NOTE: The files are of different types. Thanks in advance. Improve this question. Dekel Ayan Ayan 2, 2 2 gold badges 27 27 silver badges 61 61 bronze badges.
How are you sending the file you've downloaded to the user? If you are asking how am I downloading file, well that is what I want to know how should I download the file. It looked like you were asking how to show the progress, but on second read, this is an extra to the download. Simple answer: don't use ajax to download a file, use the browser. Yes that can be obviously done but I need to show the download progress as it is the part of the UI — Ayan.

Thanks a lot. If the file is big enough it's not good to put it in RAM. If it's small then a progressbar is not very usefull. This does not seem like a good idea. Show 4 more comments. Sign up or log in Sign up using Google.
