File download with ajax

The HTML will look something like this:. So to add Axios without too much fuss for this case, I added the following script tag in the head of the page:.

So now that the infrastructure is in place, we can go on and start implementing the getArchiveAjax function. We will start simple just so that we can also learn what the issue is. Through this you can find whether download is being started, happenning or has been completed.

The above codes downloads the file and sets the object URL - basically the user has to click twice to download a file.

You can also create the link dynamically, and invoke a click on it so that the user has to click once to download the file. Updated on January 3, Published on February 6, Elvin Acevedo Jun Go to top.

Introduced me to 3 new concepts I did not know about: 1 separating the request for file creation from the further request to download the file; 2 BlockUI jQuery plugin; 3 ActionFitlerAttribute.

Re: My vote of 5 winsonet Aug Thank you for your support. You can put a link on the page with the URL to your file returned from the ajax call or another way is to use a hidden iframe and set the URL of the source of that iframe dynamically. This way you can download the file without refreshing the page. Now a days almost every websites supports download file feature. Now as a developer we face several issue when providing such funtionality. Let see the problems:.

So we have to find a way to overcome such problems and the solution is zipping the file. Zipping files also has its own benefits apart from solving the mentioned problems like it also compress the file size thus making web bandwidth consumption low and thus increasing website as a user experience. So let's start it. The background is the knowledge of MVC. You should know how to add a project in MVC and add a Controller. If you wants to start with MVC first you can learn it from my other articles as listed below: As we will be using ajax so knowledge of Jquery is also pre-requisite.

We will be creating a page which will be having a button that will post a ajax request to server and server will return file as a zip. We also be using javascript FileSaver. Please visit this link FileSaver. Now add an MVC project. I assume that you have created a HomeController and Index method in it.
