Controling Google Earth from JScript

Simon's recent post on controlling Google Earth from C++ got me thinking about doing the same thing in JScript. It turns out it's pretty easy: you just need set up an <object> element with the right class id. As an example, here's a small HTML document that launches Google Earth and then navigates to my house on the click of a button:

(Note that may need to enable ActiveX controls to get this to work. You'll also need to have Google Earth installed too)

function moveToCoordinates(lat, long)
var viewInfo = googleEarth.currentView;
viewInfo.latitude = lat;
viewInfo.longitude = long;
viewInfo.range = 1000;
viewInfo.tilt = 45;
viewInfo.azimuth = 30;
googleEarth.setView(viewInfo, 0.1);
catch (e)
onclick="moveToCoordinates(51.5256937588635, -3.20453415360346)"
Go To Steve's House

(Interestingly, inserting the <object> element into this post causes Google Earth to launch everytime this blog entry loads).

Is this just for IE-based browsers?

Has anyone figured out how to call SaveScreenShot? I've tried and can't seem to get the "quality" paramter correct.

This does not work for me. The line 'var viewInfo = googleEarth.currentView;' always returns NULL. I have google earth plus, so I uninstalled that and reinstalled plain google earth, but the behaviour did not change. Any ideas?
