I just need to get the height of the content of an object tag when assuming the object is a webpage(on the same site.)
I appreciate any help in advance.
Thanks guys! I know there's a way to do it.
EDIT
<object id="blogs-and-stuff" data="blog/index.php" class="blog-stuff" type="text/html" style="width:900px; margin-left:50%;">
I want the height of index.php in the preceeding, not the height of ".blog-stuff".
$(".blog-stuff").height() //does not return what I need.
EDIT EDIT
Im trying to grab the height of the webpage inside the object tag and apply it to the object tag. This would increase the size of the object to show the entire webpage its holding rather than using scroll bars. Overflow is not working as planned. This screen shot shows only the object with the webpage in it
Sorry for the confusion guys.

Give an example. Right now I understand that you want to get the height of a webpage – Huangism Commented Mar 12, 2014 at 19:14

Reset to default 6Access the content of Object
The real challenge seem to be how to access the content of the Object element. The solution I found is to use the contentDocument
property of the object
element. I put together a small test case where you log the height of the object
content.
document.getElementById("object_id").contentDocument.body
Make sure the object
content is loaded before you try and access its height.
<object id="test" data="test.html" ></object>
<button id="button">Log height</button>
<script src="//ajax.googleapis./ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script>
$("#button").click(function() {
console.log(document.getElementById("test").contentDocument.body.getBoundingClientRect().height)
});
</script>
However, you will run into problem if try to load an external URL in your object. https://developer.mozilla/en-US/docs/Web/JavaScript/Same_origin_policy_for_JavaScript
Then there are a few different methods that will get the height of an HTML element.
Pure JavaScript options:
element.style.height
document.getElementById("input_id_here").style.height;
Description:
The height CSS property specifies the height of the content area of an element. The content area is inside the padding, border, and margin of the element.
https://developer.mozilla/en-US/docs/Web/CSS/height
element.getBoundingClientRect().height
element.getBoundingClientRect().height
Description:
Returns a text rectangle object that encloses a group of text rectangles.
https://developer.mozilla/en-US/docs/Web/API/Element.getBoundingClientRect
element.clientHeight
element.clientHeight;
Description:
Returns the inner height of an element in pixels, including padding but not the horizontal scrollbar height, border, or margin.
clientHeight can be calculated as CSS height + CSS padding - height of horizontal scrollbar (if present).
https://developer.mozilla/en-US/docs/Web/API/Element.clientHeight
HTMLelement.offsetHeight
document.getElementById("input_id_here").offsetHeight;
Description:
Height of an element relative to the element's offsetParent.
https://developer.mozilla/en-US/docs/Web/API/HTMLElement.offsetHeight
jQuery options
*height("input_selector_here")*
$("input_selector_here").height()
Description:
Get the current puted height for the first element in the set of matched elements.
https://api.jquery./height/
outerHeight()
$("input_selector_here").outerHeight()
Description:
Get the current puted height for the first element in the set of matched elements, including padding, border, and optionally margin. Returns a number (without "px") representation of the value or null if called on an empty set of elements.
https://api.jquery./outerHeight/
innerHeight()
$("input_selector_here").innerHeight()
Description:
Get the current puted height for the first element in the set of matched elements, including padding but not border.
https://api.jquery./innerHeight/
I do not like jQuery so my answer will use native javascript....
document.getElementById('your-object-id').getBoundingClientRect().height;
document.getElementsById("object").style.height
This should be the fastest solution, as it does not rely on an extra function call like the other jQuery solutions.
