I need to dynamically initiate a download with javascript. I have seen how people do this by doing something like
window.open("some url", "Download"); but I need to do it without changing the url of the current page (and not using frames if I can help it, or created and destroying a frame dynamically). Anybody know how to do this?

To trigger a file download on a button click we will use a custom function or HTML 5 download attribute. The download attribute simply uses an anchor tag to prepare the location of the file that needs to be downloaded.
Did you know you can create files using JavaScript right inside your browser and have users download them? You can create files with a proper name and mime type and it only takes a few lines of code.
You don't need window.open(). It's plain ugly and prone to popupblockers (where you have no control over in clients). Just window.location is sufficient if the response header of the requested download URL contains Content-Disposition: attachment. This won't change the current URL in the browser address bar nor the current page, but just pop a Save As dialogue.
E.g.
window.location = 'http://download.winzip.com/winzip145.exe'; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
