Download file using jquery
Posted by: admin November 4, Leave a comment. I have a jquery-based single-page webapp. It communicates with a RESTful web service via AJAX calls. I also have 3 working from the web-service point of view, meaning it will create and return a binary file if given the correct JSON parameters.
Is it possible to get a downloadable file back from an ajax call like this? How do I get the browser to download and save the file? Another idea is to download file using jquery the PDF and store it on the server and return JSON that includes a URL to the file. Then, issue another call in the ajax success handler to do something like the following:. But doing that means I would need to make more than one call to the server, and my server would need to build downloadable files, store them somewhere, then periodically clean up that storage area.
Not use ajax and instead submit a form post and embed my JSON data into the form values. Would probably need to mess with hidden iframes and such. Not use ajax and instead convert my JSON data into a query string to build a standard GET request and set window.
href to this URL. May need to use event. preventDefault in my click handler to keep browser from changing from the application URL. Use my other idea above, but enhanced with suggestions from the naikus answer. Submit AJAX request with some parameter that lets web-service know this is being called via an ajax call. If the web service is called from an ajax call, simply return JSON with a URL to the generated resource.
If the resource is called directly, download file using jquery, then return the actual binary file. The more I think about it, the more I like the last option. This way I can get information back about the request time to generate, size of file, error messages, etc. and I can act on that information before starting the download. The downside is extra file management on the server.
This will wipe out any event bindings your page has, amongst other things. Create an element and use appendChild instead. php with the data in the variable postData; if that post completes successfully, add a new iframe to the body of the page. Adding an iframe to the page that references that URL will result in the browser promoting the user to download the file, assuming that the web server has the appropriate mime type configuration.
It will only download the file in Chrome, Firefox and Opera, download file using jquery. This uses a download attribute on the anchor tag to force the browser to download it. I know this kind of old, but I think I have come up with a more elegant solution. I had the exact same problem.
The issue I was having with the solutions suggested were that they all required the file being saved on the server, but I did not want to save the files on the server, because it introduced other problems security: the file could then be accessed by non-authenticated users, cleanup: how and when do you get rid of the files.
And like you, my data was complex, nested JSON objects that would be hard to put into a form. What I did was create two server functions. The first validated the data.
If there was an error, it would be returned. Then, on the client, I have a form that has only one hidden input and posts to a second server function.
I set the hidden input to the base64 string and submit the format. The form could submit to a new window or an iframe on the page and the file will open up. In short, there is no simpler way, download file using jquery. You need to make another server request to show PDF file.
It is been a while since this question was asked but I had the same challenge and want to share my solution. Instead of saving the file between the requests, it saves the post data. Download file using jquery seems to be download file using jquery simple and effective.
I think the best approach is to use a combination, Your second approach seems to be an elegant solution where browsers are involved. So depending on the how the call is made. whether its a browser or a web service call you can use a combination of the two, with sending a URL to the browser and sending raw data to any other web service client. Not entirely an answer to the original post, but a quick and dirty solution for posting a json-object to the server and dynamically generating a download.
and then decoding the json-string at the serverside and setting headers for download PHP example :. I have been awake for two days now trying to figure out how to download a file using jquery with ajax call.
