xml will work: EXAMPLE. That excel file is created by the server and returned as a response to the client. Download that response as a file with custom name in browser ". Here we need to carefully set few things on the server side. I set few headers in Python Django HttpResponse. You need to set them accordingly if you use other programming languages. Since I download xls excel here, I adjusted contentType to above one. You need to set it according to your file type. You can use this technique to download any kind of files. The params are sent as proper post params as if coming from an input rather than as a json encoded string as per the previous example. CAVEAT: Be wary about the potential for variable injection on those forms. There might be a safer way to encode those variables. Alternatively contemplate escaping them. My approach is completly based on jQuery. The problem for me was that it has to be a POST-HTTP call. And I wanted it to be done by jQuery alone.

What I and many others do is to create a link on the webpage, indicating that the target should be downloaded and putting the result of the http-request as the target. After that I append the link to the document than simply clicking the link and removing the link afterwards. You don't need an iframe anymore. The interesting point is that this solution is only working with a " blob ". As you can see in other answers, some are simply using a blob but not explaining why and how to create it. As you can read e. in the Mozilla developer documentation you need a file, media ressource or blob for the function " createObjectURL " to work. The problem is that your http-response might not be any of those. Therefore the first thing you must do is to convert your response to a blob.

This is what the first line does. Then you can use the " createObjectURL " with your newly created blob. If you than click the link your browser will open a file-save dialog and you can save your data. Obviously it s possible that you cannot define a fixed filename for your file to download. Then you must make your response more complex like in the answer from Luke. And don't forget to free up the memory especially when you are working with large files. For more examples and information you can look at the details of the JS blob object. Here is what I did, pure javascript and html. Did not test it but this should work in all browsers. I try to download a CSV file and then do something after download has finished. So I need to implement an appropriate callback function. Using window. Something like this, change header so it is not a good idea.

fetch is a good alternative however it cannot support IE And window. createObjectURL cannot support IE You can refer this. This is my code, it is similar to the code of Shahrukh Alam. But you should take care that window. createObjectURL maybe create memory leaks. When response has arrived, data will be stored into memory of browser. So before you click a link, the file has been downloaded. It means that you can do anything after download. Use window. And that way, the browser should prompt the user to save the file to disk, instead of just showing them the file. It will also automatically close the tab that it just opened. lets say you have your byte array declare and populate, the only thing you need to do is to use the File function using System. and then you will be able to call your controller to download and get the "success" or "failure" callback. I found a fix that while it's not actually using ajax it does allow you to use a javascript call to request the download and then get a callback when the download actually starts.

I found this helpful if the link runs a server side script that takes a little bit to compose the file before sending it. so you can alert them that it's processing, and then when it does finally send the file remove that processing notification. which is why I wanted to try to load the file via ajax to begin with so that I could have an event happen when the file is requested and another when it actually starts downloading. I think there's a way to read get data using js so then no php would be needed. but I don't know it off hand and the server I'm using supports php so this works for me.

thought I'd share it in case it helps anyone. If the server is writing the file back in the response including cookies if you use them to determine whether the file download started , Simply create a form with the values and submit it:. If you want to use jQuery File Download , please note this for IE. You need to reset the response or it will not download. Your action can implement ServletResponseAware to access getServletResponse. This is helpful in case when you want to decide whether or not file needs to be downloaded after making form.

submit , eg: there can be a case where on form. submit , an exception occurs on the server side and instead of crashing, you might need to show a custom message on the client side, in such case this implementation might help. there is another solution to download a web page in ajax. But I am referring to a page that must first be processed and then downloaded. getElementById 'form1' ; fetch api, { body: form, method: "POST"}. attr 'download', 'Attachement. fadeIn , function { } ; }. I have tried Ajax and HttpRequest ways to get my result download file but I've failed, finally I've solved my problem using these steps:.

this data was encoded to json, and put json in input:. and done! while my result is a file xlsx file for me the page wouldn't be redirected and instantly the file starts to download in last page, so no need to useiframe or window. open etc. I struggled with this issue for a long time. Finally an elegant external library suggested here helped me out. We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here.

Specifically on how you solved the problem. for example, is it instead posting to an iframe? is it instead requiring the remote script to save the file and return a url to it? asgerhallas Sure, but that's completely useless if said link goes away. I agree, a blog is a far better place to place a lengthy description of how to use your plugin and how it works. but you could have at least gave a short overview of how this plugin solves the problem. For example, this solves the problem by having the server set a cookie and having your javascript continuously look for the cookie until it exists. Once it exists, we can assume that the download is complete.

Royi, as I understand it AJAX can never support file downloads that result in a file download popup to save to disk. Have you found a way that I'm unaware of? Show 14 more comments.

Note that this requires the server to be setting a Content-Disposition header value of 'attachment', otherwise the browser will redirect to and display the response content — brichins.

I might suggest this, as a more gracefully degrading solution, using preventDefault :. If you don't want search engines to index certain files, you can use robots. txt to tell web spiders not to access certain parts of your website. If you rely only on javascript, then some users who browse without it won't be able to click your links. JavaScript isn't a good way not to index a page; it won't prevent users from linking directly to your files and thus revealing it to crawlers , and as Rob mentioned, wouldn't work for all users.
