It works pretty similarly with an iframe but has some cool features that I have found quite handy:. Just call window. Reading the answers - including the accepted one I'd like to point out the security implications of passing a path directly to readfile via GET.
The given script will happily send any file the webserver-user has access to. Please refer to this discussion for information how to prevent this: How do I make sure a file path is within a given subdirectory?
A agree with the methods mentioned by maxnk, however you may want to reconsider trying to automatically force the browser to download the URL. It may work fine for binary files but for other types of files text, PDF, images, video , the browser may want to render it in the window or IFRAME rather than saving to disk. If you really do need to make an Ajax call to get the final download links, what about using DHTML to dynamically write out the download link from the ajax response into the page?
That way the user could either click on it to download if binary or view in their browser - or select "Save As" on the link to save to disk.
It's an extra click, but the user has more control. To get around the security flaw in the top-voted answer, you can set the iframe src directly to the file you want instead of an intermediate php file and set the header information in an. I suggest to make an invisible iframe on the page and set it's src to url that you've received from the server - download will start without page reloading.
Or you can just set the current document. But that's can cause for user to see an error if the requested document actually does not exists. Using the glob function I tested the download file in a path one folder up from the file to be downloaded I was able to make a quick array of files that are "allowed" to be downloaded and checked the passed path against it. Not only does this insure that the file being grabbed isn't something sensitive but also checks on the files existence at the same time.
I'd suggest window. If it's a download, there will be no window and you will get your file. If there is a or something, the user will see it in a new window hence, their work will not be bothered, but they will still get an error message.
Why are you making server side stuff when all you need is to redirect browser to different window. In the past, popular browsers have made automatic downloads difficult to execute due to safety concerns. This way of making JavaScript download files allows users to retrieve the content provided in the text area. The file reaches the computer device as a simple.
The declared function sets a download attribute where you get to name the file. The encodeURIComponent function then encodes the content.
The click method prompts the download process to start as you click the download button. There is another option for downloading files without contacting the server. This time, we are using a JavaScript library called FileSaver. The example below presents the syntax to implement the saveAs FileSaver interface:. Together they seems to be perfect solution for JavaScript files downloading.
Click on link method also have not such problem as empty window in Chrome or Safari. However we can create hidden link and programmatically click on it by dispatching new mouse event. What else can annoy user? And it can be avoided by using HTML5 download attribute.
This attribute will tell browser that virtual link we created is aimed for download only. Project on GitHub. Header also has one more advantage — it prevents some file types e. Thank you for this code. Report Error.
