The standard trick is to use a hidden IFRAME - that lets you download
without replacing your current page. My code looks like:
url = 'full-size/' + encodeURIComponent(album.title).replace(/'/g, '%27') +
'/' + encodeURIComponent(metadata.fileName).replace(/'/g, '%27');
if (/webOS\/\d+\.\d+|hpwOS\/\d+\.\d+\.\d+|Mobile\S* Safari\/\S+|Android
\d+\.\d+/.test(window.navigator.userAgent)) {
window.open(url, '_blank');
} else {
iframe = document.getElementById(hiddenIFrameID);
if (iframe === null) {
iframe = document.createElement('iframe');
iframe.id = hiddenIFrameID;
iframe.style.display = 'none';
document.body.appendChild(iframe);
}
iframe.src = url;
}
The if-statement handles several mobile browsers that don't work with the
hidden IFRAME trick. There, the code just opens the file in a new window.
If it's a picture, you can long-tap or some such to save it. I've never
tried to download a PDF, so iOS may still not play nice.
