The file will be downloaded as BLOB using jQuery AJAX and XmlHttpRequest (XHR) request and then the file will be downloaded using the Response inside the Success event handler of jQuery AJAX function. TAGs: Excel, AJAX, jQuery, Word, PDFEstimated Reading Time: 2 mins I want users can download a certain files generated but I can't force to download this files, and I tried several ways to do it. Mails with files attached (3 different ways) or by forcing the file download through the web browser Nothing happens. I have this configuration in JS (jQuery) to PHP script 18/05/ · jQuery File Download is a cross server platform compatible jQuery plugin that allows for an Ajax-like file download experience that isn’t normally possible using the web. Demo of blogger.com in action with some different examples. Example VS MVC 3 application using blogger.com
Jquery download file from server
Tags: Ajax File Download · Javascript File Download · jquery file download · jQuery Plugin · jquery. The href in the instructs the browser to browse to the location indicated.
This is equivalent to setting the window. location of a page using JavaScript. When the response comes back the HTTP response headers can contain many different things in fact almost anything. Here are some examples:. The browser responds by opening up a file download dialog or ribbon for the user to download the file.
The response from a file download error is generally no different from a jquery download file from server HTML response, the only difference here is that is has an error message as HTML content. The browser will now happily replace your existing page and address with the new error message, jquery download file from server.
Not only have we now displayed an ugly error message to the user but we have also caused them to leave whatever page they were on. Imagine you have created a nearly exclusively Ajax site like Gmail. A response like this from the server will cause your entire DOM to be replaced by an error message. Imagine this happening to you in Gmail and having to load up everything all over again. Well how the heck does that work? The answer is:.
I have to rely on Web. An iframe which is generally a mortal sin of modern web development can exist in a DOM but in most respects is treated like an entirely different window. By dynamically inserting a hidden iframe into the DOM and setting its location to the desired file path we can initiate a file download just like it was occurring in the main application window.
This directly gets us around one of the nasties of file downloads — if an error occurs the user has now been forced off of the page they were on which may contain an Ajax application like Gmail to see an ugly error message, jquery download file from server.
Like a normal file download in the main window an iframe will never fill with content when a successful file download occurs. It simply contains an empty DOM. Well how do we detect what is going on if nothing happens when jquery download file from server file download is successful.
Well this is where the cookie comes in:. Since the creation of cookies exists in HTTP headers, which is standard fare for all web requests and responses, we can actually write a cookie to indicate that a file download has been initiated properly instead of an error page.
The response from the web server will now look something like this:. Once a download is initiated on the iframe a configurable duration poll of cookies and the iframe contents occurs.
If the iframe fills with contents then we know a file download has occurred in most cases, make sure to set a MIME type! jQuery File Download is easy to use in the simple case but also allows for various callback options as well, jquery download file from server.
Use of the very simple approach only protects you from the page changing in the event of a file download error. This alone is pretty useful, jquery download file from server. This will result in an alert dialog telling you a file download initiation has just occurred for jquery download file from server specified URL. If a failure occurred it will display the attempted URL and error message in a dialog. You can see this one running at the top of the demo page. In order for the below code to work for you, you will also need jQuery UI installed and an image if you want as a downloading spinner.
This demo does almost the same thing as above but handles the modals manually by using the callbacks and it uses modal HTML that already exists on the page. HTML for jQuery UI Modals place anywhere on page.
Only the MVC 3 server code has been tested. Actually if you want to see it running just head over to the demo page. Just make sure to write a cookie in the same HTTP response as the file download occurs with, that results in this HTTP Response Header using default configuration :. If you are using a Controller Action to serve up your files I hope you are! you can very easily enable automatic cookie writing by inheriting your Controllers from a base class that writes the cookie automatically for you, jquery download file from server.
