If an <IMG> specifies a WIDTH but not a HEIGHT, then height is internally determined so as to maintain the image's aspect ratio. Aspect ratio is also preserved if HEIGHT but not WIDTH is specified.
What is the value of an unspecified HEIGHT or WIDTH attribute. How do I dynamically set the attribute to unspecified, after having previously used the <IMG> with explicit HEIGHT and WIDTH attributes?
How do I standardise the width of the top menu items in a (Superfish) Suckerfish style menu (V 1.4.8) as each is sizing to the text and I would like all to be equal
View 3 Replies View RelatedI'm working on my personal website [URL] and I'm trying to use Javascript to edit some of the height and size attributes of elements on the page, based on the user's window size. I've got the code that gets the window size working, and calculates what I want to set as the "boxSize" but the part that goes into the external CSS to change the values is not working. "boxSize" is a variable that holds just a number. I'm not sure if it's really stored as a number or a string, but I don't think that's supposed to affect anything.
I'm just putting in the relevant part of the code right where it's failing. I figured out (using alert() statements) that the script is definitely working right up until before the two lines given, and failing to get through them.

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" />
</div>
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 myWidth=myImage.style.width; //attempt to capture width of <img>
var myHeight=myHeight.style.height; //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.
I have the correct height and width for an image, however when I set the Javascript pop up to this height and width it does not display all of the image.
Does Javascript use different dimensions or what? And how can I set the height and width for it to compensate for Javascript's mistake?
I have the following code:

I can't make the browser to read the style.width and style.height from the CSS. Does anyone know a fix for that, so that I don't have to use inline styles for every div?
How can I get the width and height of an object? I try
document.getElementById('tooltip').width
but it returns "undefined" in IE / Mozilla
My object is a DIV with dynamically changed "style.width" from "" to "600"
--------------------
Basically I want a DIV layer with at most 600px width
(if text inside has greater width then 600 else text width)
So, I try this:
my_object.style.width="";
if (my_object.width > 600) then my_object.style.width=600;
But as I say, my_object.width is not working
I was wondering if you can in CSS create an <img> tag with an Id? Then use that image tag in the body tag to refer to make it the background image. If you can I think I would then be able to resize the background image using DOM and javascript to fill the browser window without having to repeat the image, maybe?
I'm thinking this might work because.
1. Can't you create a style for any html or xhtml tag (element)?
2. The image tag has a height and width attribute.
3. If a tag (element) has an Id in the CSS you can control its attributes with DOM or javascript?
4. I should be able to use the Image tag by Id reference in the body tag - background attribute?
Suppose I have an image - "image.gif" How to know its width and height ?

I don't need to modify the page in anyway. Just get the width and
height. I can reference the page in an iframe, cfhttp (CFMX) or
something if it needs to be on my server.
How can I get visible viewport dimensions of any browser?

I can't for the life of me figure out how to do this or find anyone in Google trying to either. This has to be the first time I've ran into a limitation of jQuery and it isn't even something that should be such a problem.

i need the innerHeight and innerWidth of the clients browser window to be returned from a function. here is what i have however some times the value being returned is in fact greater than the browser window (only by a few pixles) i'm assuming this has something to do with 'tabs' in my browser.
function getW(){
var w;
if(document.innerWidth){ w=document.innerWidth;
} else if(document.documentElement.clientWidth){ w=document.documentElement.clientWidth;
} else if(document.body){ w=document.body.clientWidth; }
return w;
}
function getH(){
var h;
if(document.innerHeight){ h=document.innerHeight;
} else if(document.documentElement.clientHeight){ h=document.documentElement.clientHeight;
} else if(document.body){ h=document.body.clientHeight; }
return h;
}
i'm returning the value into a Math.random()*getH();
i'm using the value from that to randomly position a single character on the page.
I have a simple form with file control. I want to check out uploaded image's width and height on client side.
View 2 Replies View RelatedHow can I change the height and width of an element with Javascript? I have tried and so far I can only change either the width or height but not both, doing something like this…
Code:
<HTML>
<HEAD>
<script type = "text/javascript">
function changeSize(){document.getElementById('test').style.height = '200'}

And this works fine but if I try to change both height and width it doesn’t work. Doing something like this doesn’t work

im using the following javascript function to popup a new window that will display the full size of thumbnail images.
However, whenever I click on an image, the full image will not appear. Only a very small window will appear. How can I alter the function below so that the full image will appear?
function popUp(URL) {
day = new Date();
id = day.getTime();
eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=100%,height=100%');");
}
I heard it's not possible to get the width and height of a flash file using PHP and that's only possible through JavaScript.
View 3 Replies View RelatedI set the height of an object to "100%", via its HTML definition. I later want to determine the actual height of it, using JavaScript. If I access its "height" property it returns the string "100%". How do I get the actual height, in pixels, that it ended up being when it got displayed by the browser?
View 1 Replies View RelatedI want to preload some images for a webpage _and_ determing their width and
height. The problem is that the scripts continue while the images are loaded in the
background, while I need the thus undefined values of image.width and image.height.
Thus I'm looking for a function which stops executing my script until the
images are all fully loaded.
Some non-working sample code included. Notice this only doesn't work well on Firefox. The code runs without errors, but it doesn't get the correct height and width. To see the
problem the images used shouldn't be in the browser cache. Code:
I wonder to show the images in a table format... and to set a box of
width 100px and height 100px, is there a way?
Right now, if I set width to 100px, then height can be 180px...
If I set height to 100px, then width can be 260px...
What I really want is, to have the greatest width and greatest height
so long as none of them exceed 100px, and maintaining the aspect
ratio. (I don't want to set both width and height to 100px for the
aspect ratio will be weird...)
so powerful as HTML and CSS is, is the above possible?
So it might be possible to use Javascript... but what about for users
who have javascript turned off? and because I am loading the jpg
files in one .php, and posting to another .php file and setting the
HTML in the second file... so getting the width and height info in the
first page and passing it to the second .php can be kind of messy.
Im working on a site for a friend, and we've setup a popup window for a couple pages, but with the code we have, the variables for the width and height are in the <script> portion of the code, and not on each individual popup code segment. Is there a way I can add "width=400" or something to each popup to change its width? Code:
