The superior method is to expose the C/C++ API to WebKit to elisp.
However, no one has yet done the work to make this happen.

We do not want to use the JavaScript method you suggest long term
because system safety requires that JavaScript be turned off when
browsing certain content, such as email. If we depend on JavaScript
under such circumstances, we will cease to be able to control the
window and view untrusted content safely at the same time.

For the moment, however, it works okayish.
