OffsetHeight - Get The Height Of A <div> Tag

Sep 16, 2007

I'm trying to get the height of a <div> tag so I can use it as a reference in a function to change image height, but I can't seem to get it.

function getdimensions()
RightContent = document.getElementById("Right").offsetHeight;
LeftContent = document.getElementById("Left").offsetHeight;
return LeftContent, RightContent;
window.onload = function() {

I have that, and the div tags have the corresponding ID's, but when I try one of these html buttons to test I just get 'undefined'.

<button onclick="alert(RightContent.offsetHeight);">Right Height</button><br>
<button onclick="alert(LeftContent.offsetHeight);">Left Height</button>

What's going wrong?

Offsetheight Displays 0 In IE

Nov 14, 2007

i've got a .net page with a table sitting in it that has no specified height.
I want to be able to grab the height of a specific table (ID="printIntro"). Firefox spits out a number, but IE regardless of version spits out a big fat 0.

from what i understood, IE should be able to understand offsetheight, no?
here's a snippet of a VERY simplified version of what .net generates, as you will see IE will return 0: Code:

Apr 28, 2011

Getting The Height Of A Div

Dec 21, 2006

i am trying to get the pixel height of a div containing some text. i did not manually set the height in the style.

i have tried the following:

var pHeight = document.getElementById("artComment").scrollHeight;

var pHeight = document.getElementById("artComment").offsetHeight;

both of the above examples worked fine in firefox but not in IE 6 or 7. IE writes a zero. firefox writes the actual height (261).

Height Of A Page

Oct 28, 2005

I need to know the height of the *page,* not the viewport. So if I've
got a page that is like twice or three times the height of the viewport,
does anyone know of any way to calculate that using JS?

It's a nutty idea I suppose, but here's the backstory: I have a client
who has a site whose content is being generated by some crappy database
software he is pretty much married to. The site looks like the Web era
1994, and he wants to give it a facelift, but get this -- he doesn't
want to change the css stylesheet that the database company is supplying
him with, because everytime they issue an update to their software,
there's a new stylesheet, and he doesn't want to have to integrate their
changes into whatever stylesheet he's using. Whatever.

So I mulled this over for a while and suggested that we put the db crap
into an iframe and then surround it with a nice, well-designed margin
that matches that of the larger institution. Far from perfect, but I
thought it was a pretty good idea. Unfortunately he says the iframe
can't have a scrollbar -- it has to fit all the content of the page.

So I made the iframe really big, and his response: oh, but it has all
this ugly whitespace at the bottom.

Long story short (too late), I have to figure a way to adjust the height
of the iframe on the fly. I've got no idea if this is humanly possible.

Any clever ideas?

<img> Width Height

Apr 21, 2006

I am trying to be able to manipulate the width and height of an <img> but do
not seem to be able.

"Yes", I know the JavaScript will "not" manip anything, which is ok. I
simply do not know how to capture the width or height. Once I can do that I
can manipulate them.

Here is the HTML for the <img>
<div class="ImgMnp" id="myImg" onmouseover="imgSize('myImg','fpImg)">
<img src="images/FirePlace.jpg" width="480" height="640" id="fpImg" />

Here is the JavaScript I tried to manipulate the <img>
function imgSize(myID,myImg)
var myDiv= document.getElementById(myID); //get correct <div>
var myImage=document.getElementById(myImg); //get correct <img>
var; //attempt to capture width of <img>
var; //attempt to capture height of <img>
alert("myWidth+, +myHeight"); //show if I this function works

Will someone please tell me what I am doing wrong.
