How do you get the rendered height of an element?
Let's say you have a <div> element with some content inside. This content inside is going to stretch the height of the <div>. How do you get the "rendered" height when you haven't explicitly set the height. Obviously, I tried:
var h = document.getElementById('someDiv').style.height;
Is there a trick for doing this? I am using jQuery if that helps.
Try one of:
var h = document.getElementById('someDiv').clientHeight;
var h = document.getElementById('someDiv').offsetHeight;
var h = document.getElementById('someDiv').scrollHeight;
clientHeight includes the height and vertical padding.
offsetHeight includes the height, vertical padding, and vertical borders.
scrollHeight includes the height of the contained document (would be greater than just height in case of scrolling), vertical padding, and vertical borders.
It should just be
$('#someDiv').height();
with jQuery. This retrieves the height of the first item in the wrapped set as a number.
Trying to use
.style.height
only works if you have set the property in the first place. Not very useful!
NON JQUERY since there were a bunch of links using elem.style.height in the top of these answers...
INNER HEIGHT:
https://developer.mozilla.org/en-US/docs/Web/API/Element.clientHeight
document.getElementById(id_attribute_value).clientHeight;
OUTER HEIGHT:
https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement.offsetHeight
document.getElementById(id_attribute_value).offsetHeight;
Or one of my favorite references: http://youmightnotneedjquery.com/
I use this to get the height of an element (returns float):
document.getElementById('someDiv').getBoundingClientRect().height
It also works when you use the virtual DOM. I use it in Vue like this:
this.$refs['some-ref'].getBoundingClientRect().height
For a Vue component:
this.$refs['some-ref'].$el.getBoundingClientRect().height
You can use .outerHeight() for this purpose.
It will give you full rendered height of the element. Also, you don't need to set any css-height of the element. For precaution you can keep its height auto so it can be rendered as per content's height.
//if you need height of div excluding margin/padding/border
$('#someDiv').height();
//if you need height of div with padding but without border + margin
$('#someDiv').innerHeight();
// if you need height of div including padding and border
$('#someDiv').outerHeight();
//and at last for including border + margin + padding, can use
$('#someDiv').outerHeight(true);
For a clear view of these function you can go for jQuery's site or a detailed post here.
it will clear the difference between .height() / innerHeight() / outerHeight()
style = window.getComputedStyle(your_element);
then simply: style.height
Definitely use
$('#someDiv').height() // to read it
or
$('#someDiv').height(newHeight) // to set it
I'm posting this as an additional answer because theres a couple important things I just learnt.
I almost fell into the trap just now of using offsetHeight. This is what happened :
I used the good old trick of using a debugger to 'watch' what properties my element has
I saw which one has a value around the value I was expecting
It was offsetHeight - so I used that.
Then i realized it didnt work with a hidden DIV
I tried hiding after calculating maxHeight but that looked clumsy - got in a mess.
I did a search - discovered jQuery.height() - and used it
found out height() works even on hidden elements
just for fun I checked the jQuery implementation of height/width
Here's just a portion of it :
Math.max(
Math.max(document.body["scroll" + name], document.documentElement["scroll" + name]),
Math.max(document.body["offset" + name], document.documentElement["offset" + name])
)
Yup it looks at BOTH scroll and offset. If that fails it looks even further, taking into account browser and css compatibility issues. In other words STUFF I DONT CARE ABOUT - or want to.
But I dont have to. Thanks jQuery!
Moral of the story : if jQuery has a method for something its probably for a good reason, likely related to compatibilty.
If you haven't read through the jQuery list of methods recently I suggest you take a look.
I think the best way to do this in 2020 is to use vanilla js and getBoundingClientRect().height;
Here's an example
let div = document.querySelector('div');
let divHeight = div.getBoundingClientRect().height;
console.log(`Div Height: ${divHeight}`);
<div>
How high am I? 🥴
</div>
On top of getting height this way, we also have access to a bunch of other stuff about the div.
let div = document.querySelector('div');
let divInfo = div.getBoundingClientRect();
console.log(divInfo);
<div>What else am I? 🥴</div>
I made a simple code that doesn't even need JQuery and probably gonna help some people.
It gets the total height of 'ID1' after loaded and use it on 'ID2'
function anyName(){
var varname=document.getElementById('ID1').offsetHeight;
document.getElementById('ID2').style.height=varname+'px';
}
Then just set the body to load it
<body onload='anyName()'>
document.querySelector('.project_list_div').offsetHeight;
Hm we can get the Element geometry...
var geometry;
geometry={};
var element=document.getElementById(#ibims);
var rect = element.getBoundingClientRect();
this.geometry.top=rect.top;
this.geometry.right=rect.right;
this.geometry.bottom=rect.bottom;
this.geometry.left=rect.left;
this.geometry.height=this.geometry.bottom-this.geometry.top;
this.geometry.width=this.geometry.right-this.geometry.left;
console.log(this.geometry);
How about this plain JS ?
So is this the answer?
"If you need to calculate something but not show it, set the element to visibility:hidden and position:absolute, add it to the DOM tree, get the offsetHeight, and remove it. (That's what the prototype library does behind the lines last time I checked)."
I have the same problem on a number of elements. There is no jQuery or Prototype to be used on the site but I'm all in favor of borrowing the technique if it works. As an example of some things that failed to work, followed by what did, I have the following code:
// Layout Height Get
function fnElementHeightMaxGet(DoScroll, DoBase, elementPassed, elementHeightDefault)
{
var DoOffset = true;
if (!elementPassed) { return 0; }
if (!elementPassed.style) { return 0; }
var thisHeight = 0;
var heightBase = parseInt(elementPassed.style.height);
var heightOffset = parseInt(elementPassed.offsetHeight);
var heightScroll = parseInt(elementPassed.scrollHeight);
var heightClient = parseInt(elementPassed.clientHeight);
var heightNode = 0;
var heightRects = 0;
//
if (DoBase) {
if (heightBase > thisHeight) { thisHeight = heightBase; }
}
if (DoOffset) {
if (heightOffset > thisHeight) { thisHeight = heightOffset; }
}
if (DoScroll) {
if (heightScroll > thisHeight) { thisHeight = heightScroll; }
}
//
if (thisHeight == 0) { thisHeight = heightClient; }
//
if (thisHeight == 0) {
// Dom Add:
// all else failed so use the protype approach...
var elBodyTempContainer = document.getElementById('BodyTempContainer');
elBodyTempContainer.appendChild(elementPassed);
heightNode = elBodyTempContainer.childNodes[0].offsetHeight;
elBodyTempContainer.removeChild(elementPassed);
if (heightNode > thisHeight) { thisHeight = heightNode; }
//
// Bounding Rect:
// Or this approach...
var clientRects = elementPassed.getClientRects();
heightRects = clientRects.height;
if (heightRects > thisHeight) { thisHeight = heightRects; }
}
//
// Default height not appropriate here
// if (thisHeight == 0) { thisHeight = elementHeightDefault; }
if (thisHeight > 3000) {
// ERROR
thisHeight = 3000;
}
return thisHeight;
}
which basically tries anything and everything only to get a zero result. ClientHeight with no affect. With the problem elements I typically get NaN in the Base and zero in the Offset and Scroll heights. I then tried the Add DOM solution and clientRects to see if it works here.
29 Jun 2011,
I did indeed update the code to try both adding to DOM and clientHeight with better results than I expected.
1) clientHeight was also 0.
2) Dom actually gave me a height which was great.
3) ClientRects returns a result almost identical to the DOM technique.
Because the elements added are fluid in nature, when they are added to an otherwise empty DOM Temp element they are rendered according to the width of that container. This get weird, because that is 30px shorter than it eventually ends up.
I added a few snapshots to illustrate how the height is calculated differently.
The height differences are obvious. I could certainly add absolute positioning and hidden but I am sure that will have no effect. I continued to be convinced this would not work!
(I digress further) The height comes out (renders) lower than the true rendered height. This could be addressed by setting the width of the DOM Temp element to match the existing parent and could be done fairly accurately in theory. I also do not know what would result from removing them and adding them back into their existing location. As they arrived through an innerHTML technique I will be looking using this different approach.
* HOWEVER * None of that was necessary. In fact it worked as advertised and returned the correct height!!!
When I was able to get the menus visible again amazingly DOM had returned the correct height per the fluid layout at the top of the page (279px). The above code also uses getClientRects which return 280px.
This is illustrated in the following snapshot (taken from Chrome once working.)
Now I have noooooo idea why that prototype trick works, but it seems to. Alternatively, getClientRects also works.
I suspect the cause of all this trouble with these particular elements was the use of innerHTML instead of appendChild, but that is pure speculation at this point.
offsetHeight, usually.
If you need to calculate something but not show it, set the element to visibility:hidden and position:absolute, add it to the DOM tree, get the offsetHeight, and remove it. (That's what the prototype library does behind the scenes last time I checked).
Sometimes offsetHeight will return zero because the element you've created has not been rendered in the Dom yet. I wrote this function for such circumstances:
function getHeight(element)
{
var e = element.cloneNode(true);
e.style.visibility = "hidden";
document.body.appendChild(e);
var height = e.offsetHeight + 0;
document.body.removeChild(e);
e.style.visibility = "visible";
return height;
}
If you are using jQuery already, your best bet is .outerHeight() or .height(), as has been stated.
Without jQuery, you can check the box-sizing in use and add up various paddings + borders + clientHeight, or you can use getComputedStyle:
var h = getComputedStyle(document.getElementById('someDiv')).height;
h will now be a string like a "53.825px".
And I can't find the reference, but I think I heard getComputedStyle() can be expensive, so it's probably not something you want to call on each window.onscroll event (but then, neither is jQuery's height()).
With MooTools:
$('someDiv').getSize().y
If i understood your question correctly, then maybe something like this would help:
function testDistance(node1, node2) {
/* get top position of node 1 */
let n1Pos = node1.offsetTop;
/* get height of node 1 */
let n1Height = node1.clientHeight;
/* get top position of node 2 */
let n2Pos = node2.offsetTop;
/* get height of node 2 */
let n2Height = node2.clientHeight;
/* add height of both nodes */
let heightTogether = n1Height + n2Height;
/* calculate distance from top of node 1 to bottom of node 2 */
let actualDistance = (n2Pos + n2Height) - n1Pos;
/* if the distance between top of node 1 and bottom of node 2
is bigger than their heights combined, than there is something between them */
if (actualDistance > heightTogether) {
/* do something here if they are not together */
console.log('they are not together');
} else {
/* do something here if they are together */
console.log('together');
}
}
Have you set the height in the css specifically? If you haven't you need to use offsetHeight; rather than height
var h = document.getElementById('someDiv').style.offsetHeight;

I am trying to create a dynamic layout of divs (100% wide top to bottom) that can be opened and closed and I don't want the content to extend beyond the bottom of the page so when the open/closed state changes I run code like this:
// BUG: maxHeight exists in the DOM but apparently cannot be programatically set
e.style.maxHeight = h;
alert('Element ' + e.id + ' was set to have a maxHeight of ' + h + ' but actually has a maxHeight of ' + e.style.maxHeight + '.');
The alert always shows no change to the max-height regardless of its initial value. This happens to be on divs. All elements have a display style of block. The debugger is showing no exceptions. Happens on Chrome, IE and Firefox. Setting max-height via a style string is no problem.
I am not doing any fancy CSS such as float, position, or border-box stuff either.
Other related answers I have seen here would seem to say this should work.
Like all dimension values in JS (height,width,top,bottom,etc.), the value(h in this case) must have a unit defined for this to work:
e.style.maxHeight = h + "px";

I was using padding to restrict the size of the content-box. I need a way to get the size of the content box width and hight in pixels.
I'm open to work around's like nesting elements, pseudo-elements, trying out something like flex box setups.
However, a vanilla JavaScript way to get these values is the subject of the question.
Example: http://codepen.io/anon/pen/lbzJi
Taken from the answer to a similar question; you can use window.getComputedStyle(element, null).getPropertyValue('css-property'); to obtain the value of a computed CSS property. In your case, you can use this for the properties padding-left, padding-right, padding-top and padding-bottom.
For example, to compute the height of the content box of your "box" div you can do something similar to the following where I assume the padding is specified as an integer (hence the parseInt);
function property(e, p) {
return parseInt(window.getComputedStyle(e, null).getPropertyValue(p));
}
var box = document.getElementById('box');
var paddingTop = property(box, 'padding-top');
var paddingBottom = property(box, 'padding-bottom');
var contentHeight = box.clientHeight - paddingTop - paddingBottom;
Try this using jquery: http://codepen.io/anon/pen/shoun
$(document).ready(function(){
$("pre").append("Total Height = " + ($("#box").height() - parseInt($("#box").css("padding-top"))));
});
Well, you could try:
element.clientHeight
element.clientWidth
-or-
element.offsetWidth
element.offsetHeight
depending on what you want, but we'd need some code to really help you out.
I have the following function for calculating the height of .node. It then takes away the height of a possible image, .node-image, from the height of the .node, and sets a column, .node-content-column to have a height that is the difference (i.e. 500 - 50 = 450; column becomes 450 in height).
function initColumnSizer() {
imageHeight = $('.node-image').outerHeight(true);
resizeHeight = ($('.node').outerHeight() + 75) - imageHeight;
$('.node-content-column').removeAttr('style');
$('.node-content-column').css('min-height', resizeHeight);
$('.node-content-column').css('height', 'auto !important');
$('.node-content-column').css('height', resizeHeight);
}
This function gets called on page load, and resizes .node-content-column as expected.
It also gets called when a div within .node is toggled using jQuery.toggle(), but this calculation returns a larger number everytime, instead of reverting back to the original once this toggle is reverted.
Can anyone see where I am going wrong with this calculation? Or if I am going about it the wrong way?
Thanks in advance!

1) Maybe the problem is in outerHeight() function (it takes into account padding and border). Try using just height or clientHeight:
var img = document.getElementById('imageid');
//or however you get a handle to the IMG
var width = img.clientWidth;
var height = img.clientHeight;
2) why do you need to cleanup the whole elements' style?
and then you try to assign height = auto, and after that: height = resizeHeight - what's the purpose for that ? check the logic of your code.
outerHeight(true) will return height + padding + border + margin. Possibly, you might want to use height() ?
Most possible is that "larger number everytime" have always constant difference -- for example 75.
May be you just have some dependecies between .node-content-column and .node?
If your nodes like .node-content-column, .node and .node-image are all singles, then it's better to use IDs for them -- not CSS classes.
