What is my browser? Download Google Chrome. 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. 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 If you don't want to generate and store the file on the server, are you willing to store the status, e.

Your "waiting" page could poll the server to know when the file generation is complete. You wouldn't know for sure that the browser started the download but you'd have some confidence. I just had this exact same problem. My solution was to use temporary files since I was generating a bunch of temporary files already.

The form is submitted with:. This will cause the load event on the iframe to be fired. Then the wait message is closed and the file download will then start. Tested on IE7 and Firefox. 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.

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.

A quick solution if you only want to display a message or a loader gif until the download dialog is displayed is to put the message in a hidden container and when you click on the button that generate the file to be downloaded you make the container visible.

Then use jquery or javascript to catch the focusout event of the button to hide the container that contain the message. 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. Then the server-side overrides this cookie with an earlier expiration age -- the completion of the server process.

As soon as the cookie expiration is detected in the JS polling, "Loading You can rely on the browser's cache and trigger second download of the same file when the file is loaded to the cache.

Thanks Eric -- that's good to know. I won't waste any more time with that approach. NET folks. Show 3 more comments. Active Oldest Votes. The client algorithm: Generate a random unique token. Show the "waiting" indicator. Start a timer, and every second or so, look for a cookie named "fileDownloadToken" or whatever you decide. If the cookie exists, and its value matches the token, hide the "waiting" indicator.
