((Invocable) scriptEngine).invokeFunction("func");
it throws an exception
javax.script.ScriptException: ReferenceError: "document" is not defined in <eval> at line number 1
回答1:
The script engine in Java provides the ability to execute Javascript code, but does not provide an emulation of a browser.
document
, window
and other objects are defined by the browsers but are not mandated to be present by ECMAScript specification (http://www.ecma-international.org/ecma-262/5.1/#sec-15).
