Html5 download attribute file name

The download attribute also triggers a force download , something that I used to do on the server side with PHP. This attribute is extremely useful in cases where generated files are in use -- the file name on the server side needs to be incredibly unique, but the download attribute allows the file name to be meaningful to user.

The download attribute is one of those enhancements that isn't incredibly sexy but is a practical and easy to add. I work with an awesome cast of developers at Mozilla, and one of them in Daniel Buchner. Daniel's shared with me an awesome strategy for detecting when nodes have been injected into a parent node without using the deprecated DOM Events API. Some are APIs we knew we've needed for years, others are cutting edge mobile and desktop helpers.

Regardless of API strength or purpose, anything to help us better do our job is a The code on this page is no longer best practice. I've chosen to use the power of Dojo and Dijit to At present, Chrome is the only browser to support this attribute. I look forward to more in the future though! Looks like it will be coming to Firefox. I still suggest both setting a proper content disposition server side, as well as a proper filename.

When people link to it directly or copy the URL location to send it by mail, the same behaviour can be maintained, as well as that it has browser support across the board. You know there is a HTTP header to do this? I can just hardly find a use-case where the download attribute is useful. Unfortunately the data: URL and download property only works as intended in Chrome.

Thank you! Since a[download] is only supported in Chrome and only the desktop, not the mobile I was needing this alternative. Very informative : all the post you have in your blog i have visited this blog a long along ago… but now i am feeling guilty that how i can forgot such awesome blog link….

If this attribute is present and Content-Disposition: is set to inline, Firefox gives priority to Content-Disposition, like for the filename case, while Chrome gives priority to the download attribute. This actually is possible with JavaScript, though browser support would be spotty. You can use XHR2 to download the file from the server to the browser as a Blob, create a URL to the Blob, create an anchor with its href property and set it to that URL, set the download property to whatever filename you want it to be, and then click the link.

This works in Google Chrome, but I haven't verified support in other browsers. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?

Specify a value for the download attribute, which will be the new filename of the downloaded file "w3logo. We just launched W3Schools videos. Get certified by completing a course today! The code then gets a list of files from the Images folder. This is done using Directory.

GetFiles method. Note that the Select method picks only the file names skipping the folder information. We do this because we don't need complete physical path of these files. Notice the code marked in bold letters.

The code iterates through all the image files from the ImageFiles page model property. The download attribute sets a different name to be displayed in the file download dialog. The download name adds a date stamp to the original file name. Now run the Index page in the browser and try clicking on any of the links. You will be prompted with a file download dialog. The download attribute can also be used in situations where some kind of content such as images, CSV, or XML is being generated in the browser dynamically.

Suppose you are using HTML5 canvas to draw some graphics in the browser. You want to allow the end user to download the canvas content as an image file. How would you do that? The download attribute along with data URLs can be used to accomplish this task. Let's see how. The download hyperlink placed below the canvas allows you to download the canvas graphics. The Download JavaScript function is responsible for doing this job for us.

It is shown below :. The Download function first draws a rectangle on the canvas and then clears a region from the rectangle. We won't go into any details of canvas element here. Then we grab the reference to the download anchor element and set its href and download properties. The href property is set to a data URLntaining the base64 encoded e data. This is done using the toDataURL method of the canvas.

The download property is set to MyCanvas. Another use of the download attribute could be when you want the user to download dynamically generated CSV or XML data.
