In addition to DevlshOne's answer, you could also use css to make it not display:
除了 DevlshOne 的答案，您还可以使用 css 使其不显示：
var divOne = document.getElementById('1');
divOne.style.display='none';
There's a difference between the two. With visibility hidden, the space will still be consumed by the div, but you can't see it. With display='none', its as if its not there.
两者是有区别的。隐藏可见性后，该空间仍会被 div 占用，但您看不到它。使用 display='none'，就好像它不存在一样。
Pick the better one for you.

you will need to use something like this:
你将需要使用这样的东西：
document.getElementById("1").style.display = "none";

Answers above are all basically correct, but you need to be aware of a difference between display = "none" & visibility = "hidden". With display "none" the element is removed from the layout of elements on the page. With visibility "hidden" the element still occupies its space, you just don't see it anymore.
上面的答案基本上都是正确的，但是您需要注意 display = "none" 和visibility = "hidden" 之间的区别。显示为“none”时，元素将从页面上的元素布局中删除。随着可见性“隐藏”，元素仍然占据它的空间，你只是看不到它了。
