举一反三
- 下列哪种实验可用来测定致癌物质: A: Aems test B: transformation test C: fluctuation test D: eplica plating test E: Widal test
- 假设有类Test,下列可以正确创建对象的语句是( ) A: Test t=1; B: Test t=new Test(); C: Test t=new Test; D: Test t= Test();
- 当前目录是~,在/tmp目录建立test子目录,可用的命令是( ) A: mkdir /tmp/test B: mkdir test C: mkdir /test D: mkdir ./test
- 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
- 请选BC A: test B: test C: test D: test
