A simple event on button click. It creates an AjaxDownloadFile object. The AjaxDownloadFile class source is below. What worked for me is the following code, as the server function is retrieving File memoryStream. This worked for me.
Found this plugin here. This snippet is for angular js users which will face the same problem, Note that the response file is downloaded using a programmed click event. Concerning the answer given by Mayur Padshala this is the correct logic to download a pdf file via ajax but as others report in the comments this solution is indeed downloads a blank pdf. The reason for this is explained in the accepted answer of this question: To fix the blank PDF issue in post request to get stream data like PDF, we need to add response type as 'arraybuffer' or 'blob' in request.
If you have to work with file-stream so no physically saved PDF like we do and you want to download the PDF without page-reload, the following function works for us:.
Hope this will save you a few hours and spare you from a headache. Solution was this:. Include download.
I have an action class that generates a PDF. The contentType is set appropriately. Your browser sent a request that this server could not understand. Mike B.
Nayn Nayn 1, 7 30 BalusC BalusC k I can't give a hyperlink since the document is being dynamically generated on server side. Once again: It's only asking for trouble. 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. Mayur Padshala Mayur Padshala 1, 2 12 Does it work on chrome?
URL window. It is reusable. Hope that helps. George Siggouroglou George Siggouroglou 7, 6 61 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. Can't figure it out.
I use FileResult response type: File bytes, System. ParPar ParPar 4, 5 36 Turns out, they have.
The specific improvement that made this possible is the FormData interface , first introduced in Safari 5, and later in Chrome 7 and Firefox 4. Also as usual, the best way to know if the client supports this feature is object detection. If not, it may still be that the old technique can still be used although chances are slim.
If neither is, you will have to resort to some other way to do this, such as Flash argh! Last year, we fed it an instance of the File interface. This time instead, we will give it an instance of FormData. FormData gives us two ways to interface with it. Any events that you may be listening to will be called, such as onprogress or onreadystatechange. Submitting only the file The solution proposed above, albeit useful, is a bit limiting in that we are forced to submit the whole form.
Instead, we may want to submit the file independently of the rest of the form. This is common nowadays in places such as bulk photo uploaders on many social networks. Fortunately FormData also allows us to do it this way.
Progressive enhancement One immediate advantage over the old method: the data received on the server side will be indistinguishable from a normal form submission. With the old method, we had to add specific code on the server side to handle the incoming data in a specialised way. This is not necessary anymore, and removed code is debugged code!
