So I don't have access to the preventDefault function is there anyway I can wait for a user to do an action on the first file before opening the second?

What is happening is it goes straight to the third file and I can't download the first two. What kind of action are you talking about? Because im not sure you can track that. My call is window.

Then its best you create 2 pages: mysite. When each loads, you can start the file download for that page. And require the user interaction. Once the interaction has been verified then load the next page. Dan Dan 1, 1 1 gold badge 24 24 silver badges 34 34 bronze badges. I've just been using this code Dan and I've had problem in chrome where it ignores fast clicking, so had to set a timeout. IainMNorman interesting issue, a timeout seems a good enough solution, not sure how else it could be resolved — Dan.

Just a FYI to others reading this: The download attribute won't work for cross-origin requests at least with the latest version of Chrome.

I think it used to but was patched out — georaldc. This is solution that worked for me. Lukasz Dynowski Lukasz Dynowski 7, 4 4 gold badges 53 53 silver badges 83 83 bronze badges. Use element. Remove the element from the body of the document HTML page.

John Culviner John Culviner Your modern example here doesn't seem to me to make a great deal of sense.

MarkAmery that works too as other answers have indicated. That approach AFAIK doesn't give you feedback on when the download starts, when it completed and if it errored which is handy.

I could add that to the answer for a "fire and forget" option. Also the [download] attribute doesn't allow for a POST or anything exotic either. Your modern example is not quite right. It will "download" whatever the server returns. For ex, if you have an authentication error, it will return the login page or whatever the server returns and not the "downloaded file" itself.

Any idea? As mentioned in caniuse. So if your links points to another domain, it hardly works anywhere for now. For it to work on Firefox, do document. You can also do link. Show 3 more comments. Tomer 1, 13 13 silver badges 14 14 bronze badges.

Chrome downloads, but Firefox just shows the picture. Saved me the time to test it only to find out it won't work.

Also the Edge 13 implementations is buggy because the name of the file is ignored and instead you get a file with an id as the name. In my opinion, this is the correct answer to the question. The other answers make sense if you have to support older browsers and need a workaround.

I dont' think is needed. It's already setting the 'src:url' in the creation step. Please use ide. Load Comments. What's New. Most popular in JavaScript. Convert a string to an integer in JavaScript Node. Most visited in Web Technologies.
