Hello i'm trying to change the offsetHeight of an element. i used the following
document.getElementById('id').style.offsetHeight = 0;
but i saw no visible change. Can anyone help me please?
The offsetHeight
property indicates the height of the visible area for an element. It's a shorthand that contains the sum of dimensions from padding, scrollbars and borders.
However, it can't be used to change the actual size and as noted in comments, offsetHeight
is a property of an element, not style.
To modify the actual size use height
, padding
or border
.
您应该将style.height
设置为以px
结尾的字符串。
You should set style.height
and remember to add the unit at the end like 'px' , in the case you get it from offsetHeight
for example (well you know what unit you need). It's style and you have all the different units ('px','%','em', 'vh', ...etc). Here is an example:
myHeightInPx = 200;
DomElement.style.height = myHeightInPx + 'px';
Also to note is that offsetHeight return the height as a number, an integer. The unit is px. And if you get a value using it. you need always to add the unit 'px' when setting style.height, just like in above and the bellow example:
DomElement.style.height = AnotherDOMelment.offsetHeight() + 'px';
