Getting The Height And Width Of Content Fitting DIV Element?
Jul 17, 2005
I'm having an issue getting the height and width of DIV elements that have resized themselves to fit their content.
Note: I do not have a problem getting the height and width of DIV elements that I have set using Javascript. The probel is that this value appears to stick. I.e. the height is set to 150px, then the content is changed and the DIV cosumes as much height as is required (clearly more than 150px), however analysing the DOM indicates that the height is the same (though it is clearly not).
I want to know how to get hold of the 'actual' size of a DIV element that is manipulated by the content of the DIV.
I am also interested in a solution that works in IE and Firefox (at least).
I am currently using a popup window to establish the dimensions of a window, specifically based on the the width/height of the content area.
I would prefer to simply resize it and avoid the need for a popup altogether, but this is made difficult due to inconsistancies as to how resizeTo() accounts for whatever toolbars are 'on' which varies from browser to browser and platform to platform.
The site is coded to W3C (X/HTML, CSS) and the DOM/DHTML content is gradually being rewritten in accordance with the W3C DOM.).
The W3C DOM property to get/set the window content area dimensions are:
How 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'}
[code]....
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
Code:
function changeSize(){document.getElementById('test').style.height = '200' width=’200’}
I have the following DIV, that I need to position in the center of the page, I have the following code, but you can see the div is not exactly center, space I have from the top is not the same I have in the bottom, the space I have from bot side is the same.I was wandering also if I can do this dynamically, meaning the div will receive the width and height in run time, and them I will send the values to my method "centerObj" (How I can get the height and width of the div element.
Trying to get the height of an element whose height is specified in the CSS.
So I am trying to animate the height of an item, where I have: <img id="myButton" src="myimage.jpg" /> <div id="myDiv" style="height:50px;overflow:hidden"> asdklf
[Code]....
However, it only registers as 50, even if the element is 500
Is the next jQuery code the best way to decrease an elements width?[code]I tried using the next code:[code]but that's not working, also not with '-20'.Maybe it's an idea to add this functionality? It's is already used in the .animate() function for changing the position of an element.
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 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?
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?
I have a form and in that form I have a file field through that I can browse for images. Now what I want is that whatever the image file user selected i need the width and height of that image.
How can I find the height and width of a webpage? Say I want to make sure someone's webpage is within an 800X600 viewing area. Width is the most important but if I can get width, I should also be able to get 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.
I've ran into this problem more than once, there are plenty of tutorials on how to toggle/fade a hidden div that already has data placed into it, but I want to $.load() a page into an empty div ID and then toggle/fade it into view.
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'm facing the following problem: I'm using .append() method to add a new <div> on the fly and I need to read its width and height right after it's been created. How can this be doneMy current strategy to accomplish this task is:
$("#container").append( $("<div/>").append( $("<p>").html("This is a content example that goes inside my just created div")
This script changes the image, I wanted to know if there is a way to automatically resize the div's height and width based on the actual image proportions.

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.
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 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?
