I already had the modal dialog with the iframe, but I was trying to bind an event to the document load of the loading page in the iframe You solution works.

It sounded ok, but in my case iframe load event is not triggered, probably because it triggers only if content is HTML. Alternatively: myiframe. Sadly, iframe doesn't fire any event upon file download. Jerome Jaglale Jerome Jaglale 1, 17 17 silver badges 22 22 bronze badges. You save my life!

It hides the download button. Server receives the request, prepares the file for download and starts the response, setting appropriate headers as discussed in other solutions e. Client receives the response, but does not show the button , it just knows that the server has successfully created the file and the download started.

When the server knows that the file has finished downloading, it pushes a notification to the client with the token from step 1 using cometd. Client receives notification that the download finished and shows the button again. Sign up or log in Sign up using Google.

I had an html page that launched a separate php script that generated the file and then downloaded it. On the html page, i used the following jquery in the html header you'll need to include a jquery library as well :. To break this down, jquery first launches your php script in an iframe.

The iframe is loaded once the file is generated. Then jquery launches the script again with a request variable telling the script to download the file. The reason that you can't do the download and file generation all in one go is due to the php header function. If you use header , you're changing the script to something other than a web page and jquery will never recognize the download script as being 'loaded'.

I know this may not necessarily be detecting when a browser receives a file but your issue sounded similar to mine. If Xmlhttprequest with blob is not an option then you can open your file in new window and check if eny elements get populated in that window body with interval. If you have download a file, which is saved, as opposed to being in the document, there's no way to determine when the download is complete, since it is not in the scope of the current document, but a separate process in the browser.

If you're streaming a file that you're generating dynamically, and also have a realtime server-to-client messaging library implemented, you can alert your client pretty easily. The server-to-client messaging library I like and recommend is Socket.

After your server script is done generating the file that is being streamed for download your last line in that script can emit a message to Socket. On the client, Socket. The benefit of using this method over others is that you are able to detect a "true" finish event after the streaming is done.

For example, you could show your busy indicator after a download link is clicked, stream your file, emit a message to Socket. I realize most people reading answers to this question might not have this type of a setup, but I've used this exact solution to great effect in my own projects and it works wonderfully. BUT onload does not fire in IE for file downloads like with the attachment header token. Polling the server works, but I dislike the extra complexity. So here is what I do:. But really, if your sites that busy the long running process will starve you of threads anyways.

When the user triggers the generation of the file, you could simply assign a unique ID to that "download", and send the user to a page which refreshes or checks with AJAX every few seconds. Once the file is finished, save it under that same unique ID and Does anyone have a better idea?
