View 2 Replies View RelatedI'm just starting my first jQuery project (tutorial from this months Web Designer) and I've got a background image that I want to spread across the entire background, regardless of browser size. It's big, so I originally had an onload function. This works fine in Mozilla and Safari but not in IE.
My question is, can jQuery set a width and height of 100% and have it work in IE?[code]...
I have a strange issue with jQuery while using the following code :
$("#image").append('<img src="'+json.filename+'" id="cropje" alt="None" />');
$('#cropje').load(function() {
alert($(this).width());
}) .error(function(){
alert("FAIL TO LOAD IMAGE");
And the result is : 0 But it looks like the image gets loaded after the alert... How is that possible?
I am FAR FROM BEING KNOWLEDGEABLE about javascript. On my web page, I want to have a slideshow run that'll show small-ish versions of images. I don't want the whole thing re-displaying every time, so I put together a little javascript to figure out how to show the images.....
I have one ALERT in here to show me the dimensions of the window and the image, and I'm getting one or more values coming up as "0"...... Which means that image doesn't display. The image(s) are NOT zero width or height, and neither is the window..
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">

I have the task of creating an asp page that generates a standard email newsletter. The HTML Image Width and Height tags need to be set to the actual image size (no they haven't been set to a standard size on the server) as they are read in via an while loop. I believe in ASP, you are out of luck for a function that does this, so Javascript may be the way forward.
My code is as follows for the image inside an anchor tag, as you can see i tried the min and max style properties for the image, but this does not set them exactly. e.g. width="120px" height="94px", which is what is required.
I've set up jcarousel and configured it to work how I need it to, apart from one thing; I need the images to keep their width - height ratio when the browser is resized.
I'm using the Flexible carousel configuration and the width of the images changes appropriately when the window is resized, but the height stays the same, I need it to change.
I got this working in chrome and was happy until I got to check out IE8! Enough said about that.The code I have now will work (in both chrome and IE8) if I manually set the height and width of the image but I cannot get them dynamically, for instance if images have different sizes, I've been trying for a while now but cannot get anywhere with it.The code I am currently using (of my own creation) is;
$("#lightbox_image_container").html('<img id="lightbox_image" src="http://www.veritywebdesign.com/gallery/gallery_images/image.jpg" />');
$("#lightbox_image").load(function() {
// image_width = $("#lightbox_image").width();

How do I get the height and width dynamically after loading the image?
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?
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.
How can I get visible viewport dimensions of any browser?

View 3 Replies View RelatedI'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.
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’}
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?
