I have a very similar requirement specified here.
I need to have the user's browser start a download manually when
$('a#someID').click();
But I cannot use the
window.href
method, since it replaces the current page contents with the file you're trying to download. Instead I want to open the download in new window/tab. How is this possible?

Use an invisible
<iframe>
:To force the browser to download a file it would otherwise be capable of rendering (such as HTML or text files), you need the server to set the file's MIME Type to a nonsensical value, such as
application/x-please-download-me
or alternatively application/octet-stream
, which is used for arbitrary binary data.If you only want to open it in a new tab, the only way to do this is for the user to a click on a link with its
target
attribute set to _blank
.In jQuery:
Whenever that link is clicked, it will download the file in a new tab/window.

2019 modern browsers update
This is the approach I'd now recommend with a few caveats:
- A relatively modern browser is required
- If the file is expected to be very large you should likely do something similar to the original approach (iframe and cookie) because some of the below operations could likely consume system memory at least as large as the file being downloaded and/or other interesting CPU side effects.
2012 original jQuery/iframe/cookie based approach
I have created the jQuery File Download plugin (Demo) (GitHub) which could also help with your situation. It works pretty similarly with an iframe but has some cool features that I have found quite handy:
- Very easy to setup with nice visuals (jQuery UI Dialog, but not required), everything is tested too
- User never leaves the same page they initiated a file download from. This feature is becoming crucial for modern web applications
- successCallback and failCallback functions allow for you to be explicit about what the user sees in either situation
- In conjunction with jQuery UI a developer can easily show a modal telling the user that a file download is occurring, disband the modal after the download starts or even inform the user in a friendly manner that an error has occurred. See the Demo for an example of this. Hope this helps someone!
Here is a simple use case demo using the plugin source with promises. The demo page includes many other, 'better UX' examples as well.

I'm surprised not a lot of people know about the download attribute for a elements. Please help spread the word about it! You can have a hidden html link, and fake a click on it. If the html link has the download attribute it downloads the file, not views it, no matter what. Here's the code. It will download a cat picture if it can find it.
Note:This is not supported on all browsers: http://www.w3schools.com/tags/att_a_download.asp

I recommend using html5 for download instead of jQuery:
This will download your file, without opening it.

I don't know if the question is just too old, but setting window.location to a download url will work, as long as the download mime type is correct (for example a zip archive).

Maybe just have your javascript open a page that just downloads a file, like when you drag a download link to a new tab:
With the opened window open a download page that auto closes.

I have had good results with using a FORM tag since it works everywhere and you don't have to create temporarily files on server. The method works like this.
On the client side (page HTML) you create an invisible form like this
Then you add this Javascript code to your button:
This means that a lot of the annotation for the different plans & sections is the same, just in a different location on the drawing. Nesty,I am having a brand new problem that I suspect is something to do with 'selectsimilar'.My drawing contains numerous plans & sections of the same object (cable ladder) as it travels through a building.
The on the server-side you have the following PHP code in
download.php
:You can even create zip files of your data like this:
The best part is it does not leave any residual files on your server since everything is created and destroyed on the fly!

I suggest you use the mousedown event, which is called BEFORE the click event. That way, the browser handles the click event naturally, which avoids any code weirdness:

This is crazy but I don't know how to do this, and because of how common the words are, it's hard to find what I need on search engines. I'm thinking this should be an easy one to answer.
I want a simple file download, that would do the same as this:
But I want to use an HTML button, e.g. either of these:
Likewise, is it possible to trigger a simple download via JavaScript?
I'm definitely not looking for a way to create an anchor that looks like a button, use any back-end scripts, or mess with server headers or mime types.

You can trigger a download with the HTML5
download
attribute.Where:
path_to_file
is a path that resolves to an URL on the same origin. That means the page and the file must share the same domain, subdomain, protocol (HTTP vs. HTTPS), and port (if specified). Exceptions areblob:
anddata:
(which always work), andfile:
(which never works).proposed_file_name
is the filename to save to. If it is blank, the browser defaults to the file's name.

You can do it with 'trick' with invisible iframe. When you set 'src' to it, browser reacts as if you would click a link with the same 'href'. As opposite to solution with form, it enables you to embed additional logic, for example activating download after timeout, when some conditions are met etc.
It is also very silient, there's no blinking new window/tab like when using
window.open

If you can't use form, another approach with downloadjs fit nice. Downloadjs use blob and html 5 file API under the hood:
{downloadjs(url, filename)})/>
*it's jsx/react syntax, but can be used in pure html
