Scenario: You have a div with some text, this div has no css width, no jquery width, no width attribute assigned to it in any way. However it has a width due to the content that is inside it, this is undefined, reports as "null" in jQuery. My question is: is there any way to retireve the width of this div?
$(element).width() should give you the actual width. With $(element).outerWidth(includeMargin) you can even get the width including padding, border, and, if desired, the margin.
with jquery you can do below
$('#id').width()

What is the difference between Element.scrollHeight and the height returned by the JQuery $(ElementSelector).height() method.
I have seen this and this and I know that scrollHeight is the height of content, including the content which overflows outside the viewport. My question is that isn't that the same as the height returned by the height() method. I wrote this JSFiddle as a test of that.
Another difference is...
The height property sets the height of an element and does not include padding, borders, or margins; it sets the height of the area inside the padding, border, and margin of the element.
scrollHeight includes the element's padding, but not its border or margin.

height():
returns the actual height of an element in pixels.
scrollHeight():
is a measurement of the height of an element's content including content not visible on the screen due to overflow

I want to get inner html height by JavaScript. Suppose I have
<div>Content</div>
either if the div font size has increased or many divs nested inside the parent, how do I get the height of parent div?
edit: even if the nested div has border and padding too.
The accepted answer is incorrect in the case that the parent element has a height of 0, and you want the height of the content within it (which is what I believe the OP was asking for). In that case, scrollHeight is the property you want.
const divInnerContentHeight = document.querySelector('div').scrollHeight;
Using clientHeight or offsetHeight would return 0;
If it must be in vanilla JS...
var height = document.getElementById('content').clientHeight;
That will not include any borders or scrollbars in the element, just padding. If you want to include borders and scrollbars you may use offsetHeight instead.
Use clientHeight and getElementsByTagName div to get spcific div height
document.getElementsByTagName('div')[0].clientHeight
http://codepen.io/nagasai/pen/XKoxZw
Something like this?
<div id="MyDiv">Content</div>
console.log(document.getElementById("MyDiv").offsetHeight);
Include padding and border in your height calculation:
document.getElementById('myDiv').offsetHeight;
//We can do his using JQuery
//Returns the element's height
$('#content').height();
// Returns the height with padding
$('#content').innerHeight();
// Returns the height with padding and border
$('#content').outerHeight();
// Returns the height with padding,border and margin
$('#content').outerHeight(true);
you can you content(ele) scrollheight to height of content.
ele.scrollHeight
I am having trouble with inline-block elements with
width: auto;
and programatically changing the height with javascript.
Here is a jsFiddle that demonstrates it;
http://jsfiddle.net/uJZjB/2/
The idea is that if you resize your window, the javascript sets the elements' height, and the inline-block element's width automatically adjusts to fit the content.
However, the width does not auto update and it remains at the original width rather than resizing to match the width of the content.
If you cause the dom to refresh by hiding and showing the element, or changing the display style e.t.c. the widths are updated!
Please see this modified jsfiddle;

This one on chrome, now forces the width:auto; to kick in and work, on Firefox it still appears not to update.
Is there a reason why the widths wont update when set this way?
Regards,
You can set the width of the elements alongside the height to what would be expected with width:auto by taking the width of the children:
$('#myul li').css('width',$('#myul li').children().width() + 2); // compensate for border

I have a div where it nest text, images that is changed more often and so the height of the div changes accordingly..
I need to get the height of div.
I have tried the jquery $("div#ID").height(); but it always returns a value smaller than the actual height, any help please?
May be you should try,
$("#divID").outerHeight();
$("#divID").outerHeight(true); //includes margin of element
I notice that offsetwidth is a slightly bigger number. Similarly for style.height and offsetheight.
offsetWidth returns computed element's width, while el.style.width just returns width property defined in element.style by javascript and does not reflect real element's dimensions.
This means that if you will try to get a width of the element by accessing el.style, you will probably get nothing (sample), even if the width was defined in your CSS. You will get the number only if it was defined in el.style by javascript.
Furthermore, offsetWidth gives you real width of your element, including padding and border if you use content-box css box model which is default value for box-sizing. So you can think about that like you set width of the contents of the element and padding/border go on top of that (sample).
If you are using border-box css box model, you set the total width of the element, including padding and border make the content area smaller (sample). So, in this case, offsetWidth and el.style.width would return exactly the same numbers (if el.style.width was previously set by javascript).
Typically, an element's offsetWidth is a measurement which includes the element borders, the element horizontal padding, the element vertical scrollbar (if present, if rendered) and the element CSS width.

So, it's the width of your element with border and padding included. Same thing for height.
offsetWidth is a measurement in pixels of the element's CSS width, including any borders, padding, and vertical scrollbars.
clientWidth is the inner width (ie. the space inside an element including padding but excluding borders and scrollbars)
with only return the css with defined
