更新：将函数以及其他函数和变量一起加载到范围中时
String script = "function abc(x,y) {return x+y;}" + "function def(u,v) {return u-v;}";Context context = Context.enter();try { scriptableObject scope = context.initStandardObjects(); context.evaluateString(scope, script, "script", 1, null); Function fct = (Function)scope.get("abc", scope); Object result = fct.call( context, scope, scope, new Object[] {2, 3}); System.out.println(Context.jsToJava(result, int.class));} finally { Context.exit();}
