This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
This code is in the prototype library (prototype.js) and works fine in many IE 6 browsers. The very same page just breaks on a couple of machines where I suspect the JS engine maybe older although the browser version is IE 6. Is there a quick way to determine the JS engine version.
I ran my code through a JS debugger and (typeof __method) returns "function".
