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">

jquery width() and height() functions are consistently returning the wrong values for the viewport size (i.e. $(window).width). Anyone know why..or what I can do to fix it?
I'm using height() and width() to find the dimensions of some inline images in the html. FF and IE work fine, but Opera is returning incorrect values. For example, it returns 92px as the width of an image that is actually 160px wide. How can I fix this?
How can I create a popup window in a form without showing the status, menubar, location and with width of 502 and height 550?
I was doing something like this, it will popup a window, but I do not want to show the status, menubar, location, etc. The form is submitted to other site.
I have x amount of draggable & resizable divs, they work as I want them to, I am outputting the coordinates of each div in a textfield. My problem is that the textfield only displays coordinates when a div is CLICKED, so when holding the mouseBtn and dragging a div around then releasing the mouseBtn the coordinates aren't displayed in the textfield. I tried to set 'mouseup' instead of 'click' but then the divs are being dragged around all the time even tho you released the mouseBtn. The second thing is that i want to output the size of the div in another textfield, so when a div is resized the new size of that div should be displayed in the textfield.
For the size I tried to work with function showWidth(ele, w) { $("div").text("The width for the " + ele + " is " + w + "px."); } $('#test').click(function () { showWidth("paragraph", $(this).width()); }); I want to send both size and x&y of each div to a database.
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.
I'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 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.
However, I finally ran into a problem that I can't figure out. When I try and get the width of any cell in a table it's returning a width of 83 or 84. I have the table inside a div that has a width of 757px. I don't have a width set on the table itself, but each cell is set to 100px. I've tried to set the width in a css file and inline neither of which give me the 100px that I'm thinking it should return. I've tried both width(), outerWidth() and innerWidth(). The only one that returns a different number is outerWidth.
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;
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?
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.
