This script downloads all podcasts from a BBC podcasts page

getPodcasts.js

// Press F12 to get the Developer Console, then paste these 3 lines into the console:
var jq = document.createElement('script');
jq.src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(jq);

// Next, paste these two lines in to start the download.
x = 0;
$('a[href*="download/"]').each(function(){setTimeout(_ => this.click(), x); x = x + 5000;}); 

/*
How it works:
  This uses jquery to find all the 'a' tags (links) which have an href which includes the term "download".
  Then, it triggers the click event for each one, but staggers them (by 5000 milliseconds) so that all don't download at once.
