我怎样才能将两个陈述变成三元组(how can I turn two statements into a ternary)

我有两个if语句想要变成三元组但我不知道如何。

if (val === true && optval === 'car' || val === true && optval === 'truck' )view_list.style.display = 'none'; if (val === true && optval === 'buss' || val === true && optval === 'van')view_list.style.display = '';

I have two if statements that'd like to turn into a ternary but I don't know how.

if (val === true && optval === 'car' || val === true && optval === 'truck' )view_list.style.display = 'none'; if (val === true && optval === 'buss' || val === true && optval === 'van')view_list.style.display = '';

最满意答案

因为还没有人说过， switch

if (val === true) switch (optval) { case 'car': case 'truck': view_list.style.display = 'none'; break; case 'buss': case 'van': view_list.style.display = ''; break; }

Because nobody has said it yet, switch

if (val === true) switch (optval) { case 'car': case 'truck': view_list.style.display = 'none'; break; case 'buss': case 'van': view_list.style.display = ''; break; }
