Ocado Password Autocompletion

[elvum]

So, I finally got sufficiently annoyed by Ocado arbitrarily deciding to stop me choosing whether or not to store the password for their website to write a trivial Greasemonkey script to enable the functionality again. You can get it here, if you would find it useful.

// ==UserScript==
// @name           Enable Ocado password retention
// @namespace      net.elvum.ocado
// @description    Enables the retention of passwords for the Ocado website.
// @include        http://www.ocado.com/*
// ==/UserScript==

var passwordBoxes = document.evaluate("//input[@type='password']", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
for (var i = 0; i < passwordBoxes.snapshotLength; i++) {
  passwordBoxes.snapshotItem(i).setAttribute("autocomplete","on");
}
