I have no idea( )he will win.是填whether还是that?如果改成I have some

I have no idea( )he will win.是填whether还是that?如果改成I have some i have no idea that he will come back. I have no idea _when___he will come back.(whether可以吗?如果可以那if i have no idea （that） he will go abroad next week 请问that引导的是 i have no idea that when he will come back .错在哪? I have no idea _____ he is .填whom还是 who I have no idea whether the the traffic is terrible on that w 为啥I have no idea when he will be back是同位语从句 I have no idea _____ he will come there.When he comes,I will I have no idea I have no idea （that） when he will come back home那个位置可以有that I have no idea 还是 ideas
