Using the Javascript console to get at image URLs

I wanted to download 1300+ images from a Dropbox gallery. Unfortunately Dropbox’s UI is so dynamic with Javascript there’s no simple list of URLs. So instead of trying to reverse engineer their code I opened up the Javascript console after the page had loaded to extract the dynamically generated HTML links.


l = document.querySelectorAll("a.filename-link")
a = []
for (i = 0; i < l.length; i++) { a.push(l[i].href); }
for (i = 0; i < a.length; i++) { console.log(a[i]); }

Pretty straightforward, but a lot more tinkering during the process. Those URLs lead to the image page; to get to the actual JPG you have to append “?dl=1” to the URL.
