Dmjpro.

你不是吗？以为我已经在那里搜索了？另外，我没有在这里发帖。谢谢你的回复。 ：）

Didn''t you think that I already searched there? Else I didn''t post here.Thanks for your reply anyway. :)

是的，这是可能的。你给要消失的元素一个id。然后onChange of select你调用一个使用document.getElementById（" theId"）并将其样式设置为display：none

Yes it''s possible. You give the element that you want to disappear an id. Then onChange of the select you call a function that uses document.getElementById("theId") and sets its style to "display:none"
