As others have stated, you can create and submit a form to download via a POST request. However, you don't have to do this manually. One really simple library for doing exactly this is jquery. It provides an API similar to the standard jQuery. This is a 3 years old question but I had the same problem today. I looked your edited solution but I think that it can sacrifice the performance because it has to make a double request. So if anyone needs another solution that doesn't imply to call the service twice then this is the way I did it:.
This form is just used to call the service and avoid to use a window. After that you just simply have to make a form submit from jquery in order to call the service and get the file. It's pretty simple but this way you can make a download using a POST. I now that this could be easier if the service you're calling is a GET , but that's not my case.
I used this FileSaver. In my case with csv files, i did this in coffescript :. I think for most complicated case, the data must be processed properly. Under the hood FileSaver.
To get Jonathan Amends answer to work in Edge I made the following changes:. Below is my solution for downloading multiple files depending on some list which consists of some ids and looking up in database, files will be determined and ready for download - if those exist. And Yes, like others said, it is possible to do it in jQuery Ajax.
I did it with Ajax success and I am always sending response As long as you return response , success in Ajax can work with it, you can check if file actually exist or not as the line below in this case would be false and you can inform user about that:. But I am referring to a page that must first be processed and then downloaded. I know browsers block multiple file downloads, and I also have API which returns a set of csv formatted data.
If anyone can help me improve this that would be great, but it's working for me so far. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

If the server sends back headers like the other answer has, it opens in a new window - I've done it before. It would only navigate away if your server-side script returned HTML code — user PavlePredic did you end up figuring out how to manage both response scenarios, i. JSON text response or download file response? Answer is not clear and the proposed solution doesn't work.

This example sends an HttpGet request, and thus the data payload just one record ID in the request is included as parameters in the URL. But, what if I wanted to send an HttpPost request, with the data payload included as an object containing many fields in the request?

I have updated the answer. There's no dual access to DownloadAttachment method? This will call DownloadAttachment method 2 times. How to avoid that? There is absolutely no need to use ajax for this at all.
Just call window. All this is doing is making the same request twice. I have no idea why this was upvoted. Show 4 more comments. Equals Constants. Combine Path. Message ; return Content e.

Does it work on chrome? I can only see a blank pdf. Yes, it does work on all modern browsers. If you see a blank pdf, try running the ajax url in a new tab.
If you get a blank screen there as well, might be a problem with the pdf itself. If you do see a pdf file there and not in the downloaded file, do let me know on my email.

In some browsers the window. So, also do NOT use window.
If the content-disposition is set to attachment , you will just get a Save as dialogue. The parent page will stay unchanged. There is a limited Url length.
And the author is asking about POST. Show 10 more comments. URL window. It is reusable. Hope that helps. Georgios Syngouroglou Georgios Syngouroglou I had to set the responseType of xhr to arraybuffer or blob for this to work. Otherwise, this works great. I had the exact same question. All the people responding "just make it a link" doesn't help the OP. If your content is dynamic and the link you are going to is dynamic, you have to jquery it all Works great. This is a great answer, but for some reason, I just keep getting broken empty PDF.
