var foo = '123';function print() { this.foo = '789'; console.log(foo);}print();

varmyObject={foo:"bar",func:function(){varself=this;console.log(this.foo);console.log(self.foo);(function(){console.log(this.foo);console.log(self.foo);}());}};myObject.func();程序的输出是什么? A: barbarbarbar B: barbarbarundefined C: barbarundefinedbar D: undefinedbarundefinedbar

查看一下代码 ，请问输出正确的是|var Test ={| foo:"test",| func:function () {| var self=this;| console.log(this.foo);| console.log(self.foo);| (function () {| console.log(this.foo);| console.log(self.foo);| })();| }|};|Test.func(); A: test test undefined test B: test undefined undefined test C: test test undefined D: test test test test

下面哪个程序是语法正确的？ A: foo::IO() foo=do line=getLine printline B: foo::IO() foo=do letline=getLine printline C: foo::IO() foo=do letline-getLine printline D: foo::IO() foo=do line-getLine printline

下面哪个程序是语法正确的？ A: foo::IO() foo=do line-getLine n=readline::Int printn B: foo::IO() foo=do line-getLine n-readline::Int printn C: foo::IO() foo=do line-getLine letn=readline::Int printn D: foo::IO() foo=do letline=getLine letn=readline::Int printn

下面哪个程序是语法类型正确的？ A: foo::IO() foo=do line-getLine letn=readline::Int putStrLnn B: foo::IOString foo=do line-getLine letn=readline::Int putStrLnline C: foo::IO() foo=do line-getLine letn=readline::Int putStrLnn D: foo::IO() foo=do line-getLine letn=readline::Int putStrLn(shown)

在JavaScript中每隔一秒调用函数 foo( ) ，下面哪种方法是正确的？ A: setInterval("foo( )",1000) B: clearInteval("foo( )",1000) C: clearTimeout("foo( )",1000) D: setTimeout("foo( )",1000)

def foo(): y = "local" foo() print(y)

读代码: public class Test { public static void main (String args[]) { class Foo { public int i = 3; } Object o = (Object) new Foo(); Foo foo = (Foo)o; System.out.println(foo.i); } } 结果是：
