How to download file with javascript?
since the answer from @saibbyweb does not work in all browsers as I write this, i recommend an other but similar solution, tested and working in latest (as of writing) Firefox, Chrome, Opera, Edge, Safari, mobile Safari, mobile Chrome:
function downloadUrl(url){
window.open(url, '_self');
}
Needless to say you could also open links in new Tabs with _blank instead of _self, but you potentially startle Popup-Blockers by opening new tabs/windows with Javascript.
You can provide the link to this function to download the file :
function downloadURI(uri, name)
{
var link = document.createElement("a");
link.download = name;
link.href = uri;
link.click();
}
