Need Help With Finding The Dimensions Of A Div.

How To Get Div Dimensions In IE

Jul 20, 2005

I want to have an image inside a div section, like a background image. that
adjust its size to the dimensions of div container:

<body
<div class="logo" id "logot">
<img src="logo.png" id="imagelogo">
</div>

a script function retreives the div section:

oLogo = document.getElementById("logot")

but oLogo.clientWidth gets the logo.png's width instead of the div area.

I have no problems with a similar function in mozilla browser,
any idea for IE?

PopUp Dimensions

Feb 20, 2005

My site's encased in a pop-up, and since I don't know JavaScript, well, at all, I got some script from one of the many JS sites out there. I'm having an issue with it, though. It seems that different browsers are rendering its size differently, which is a bit of a hassle. For instance, it's a few pixels too tall in Firefox, but in Safari its a few pixels too wide and too tall. So, uh, what's wrong with it?

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=550,height=450,left = 362,top = 159');");
}

(...)

<a href="javascript:popUp('dLog.html')">Development Log</a>
Looks messy to me, so if anyone wants to completely fix it up...

Underlying Image Dimensions

Jul 23, 2005

Is there any way to determine the pixel height and width of an originalimage?

Specifically, If I have <IMG id=myImg src="pic.jpg" height=200 width=300> can I figure out what the original size of pic.jpg is (had I not placed the height and width attributes on the image, whether in the original tag or later via javascript)?

Crossbrowser Element Dimensions

Jul 12, 2006

I'd like to know where I can find some informations on how to retrive
element dimensions in a cross browser whay. Until now I used
offsetWidth and offsetHeight, but I know their are not standard and
they have a different behaviour on different browsers. I need a way
that includes also margins, padding and eventually border size. I know
I have to deal with doctypes, but my javascript knowledge is not so
advanced.

I would like to force the initial location of a window to the (0,0) coordinate and give it a specific width and height when it loads.

I use the following:

Code:

window.moveTo(0, 0);

}
I call this function at the onload event of the page body.
I get an error saying: "Access is denied"

Rotating Images And Different Image Dimensions

Jul 23, 2005

I am rotating images at one location of my web site. My problem is if I set the width and height of the new image before I show the new image, the old image is stretched first to the new image dimensions, and if I show the new image before setting its dimensions, the new image is stretched first to the old image dimension before it is adjusted to its own dimension. I would like to load a new image with its own dimension at the same time. How can I do this?

Change The Dimensions Of A Pop-up Video Player?

Jul 6, 2009

my website[url]... has a pop-up video player but on certain videos (speeches for example) the video is of slightly different dimensions. I can not re-encode the video so I was wondering if I could easily edit a file in notepad to change the dimensions of the player in order to enable the user to be able to see all of the player controls. In the flash folder I have .swf and .flv files. Is there another file that represents the player dimensions/controls elsewhere?In addition to this, if a video is playing and I click off of the video player (onto the greyed out background) then the video player stops. Does anyone know how to stop this happening?

AddClass On Set Of Images Based On Dimensions?

Jun 16, 2010

I've got the jquery-ui slider working on adjusting the size of my thumbnails, BUT the problem is if the image is portrait, it overflows out of the container´┐Ż*jquery to the rescue, right? Not quite.Below is the js and basic css that i'm using. Shouldn't this be applying a different class on each img element based on the height/width values? They're all getting the same class.Am I needing to do some sort of loop function for this instead?

Code JavaScript:

$("#thumbnail_size").slider({
range: "min",
min: 125,

Can Javascript Detect An Images Dimensions?

Jun 6, 2003

I'm working on an image gallery and want to popup windows that are the size of the images they're meant to show.

In php I would use getimagesize() and plug the dimensions into a new window but the server doesn't support it so I'm sort of stumped on how to dynamically size the windows appropriately. Any suggestions?

How To Set Minimal Dimensions For A Modal Window

Sep 26, 2004

I am trying to resize a modal window so that its dimensions will be minimal (based on its content). For some reason, I am getting a weird result Here is the JavaScript function I am running in the window's onload event:

function resize() {
var height = window.document.body.scrollHeight;
var width = window.document.body.scrollWidth;

var left = screen.availWidth / 2 - width / 2;// center window horizontally
var top = screen.availHeight / 2 - height / 2;// center window vertically

window.dialogLeft = left + "px";
window.dialogTop = top + "px";

window.dialogHeight = height + "px";
window.dialogWidth = width + "px";
}

I believe that I need to do these calculations because only in onload, the browser knows what dimensions it will need for the popup window. I cannot set the dimensions when invoking the window using window.showModalWindow(), because I don't know at that time how much area the browswer will need for the window.

The problem with the calculation I am doing is that sometimes I am getting an extra gray area between the client side right side, and the window's sidebar... I have attached an image to make my point more clear. I think there is a minimal limit on a modal window width and height but I am not sure.

Detecting Image Dimensions With Javascript?

Nov 28, 2006

I have some CSS/javascript which takes an image and re-sizes it on a page with a hover-over state which causes it to expand. However, this will only re-size to specific proportions (in this case 1:1).

This is fine in the case of e.g. an 86x86 image but what I want to be able to do is detect if the image has a height greater than it's width, and if so, crop the image accordingly to make it a square.

Is there a way of doing this with javascript?

Jquery :: Image Replacement Dimensions Won't Reset

Feb 12, 2010

I have a photo gallery built with XML and PHP (pulling images from a client's Myspace albums).The gallery works fine, displays thumbnails and captions, paginates properly, etc.The whole thing is loaded by AJAX into a div, which complicates things a bit, but it works.When a visitor clicks a thumbnail, the full-sized image displays in a div overlay on top of the gallery div.The overlay is hidden until a thumbnail is clicked, when it is toggled to "visibility:visible". When the overlay "close" link is clicked, the overlay is hidden again.That also works. Some of the images are too large to display properly inside the div without throwing off the layout, so I had to set a max height and width.I can't just use CSS to set the dimensions or it'll size EVERY image to those dims, and the photos are all different sizes...some wider, some longer.So I used javascript to check the image size when the thumbnail is clicked.

All of that worked.(Although strangely, if I try to toggle the visibility as part of the function rather than putting it into the link, it doesn't work!)The problem is that once the dimensions of "img1" are set, they STAY that size even when the next thumbnail is clicked.So if the first image is 800px tall, the script crops it to 640px...then the next image may only be 400px pix tall but it displays as 640px high, making it distorted.I tried to add a "resetImgSize" function to the "close" link in the overlay, setting the img1 dimensions back to 2px x 2px when the overlay is closed, but the same thing happens...Once the img1 dimensions are set to 2x2px, they stay that way even when a new thumbnail is clicked.

Script To Calculate Image Resize From Pixel Dimensions?

Oct 13, 2009

I will have two text boxes that will accept numeric values and an image. What I need is if the user change the value of box 1, the value in box 2 will automatically update depending on the pixel dimensions of the image and vice versa.

Basically I need to automatically calculate the pixel ratio of an image and then use that value to multiply by the user inputted size.

Imitate Browser Zoom - Change All Content Dimensions?

May 9, 2010

how to imitate browser zoom with javascript?I know you are not allowed to control browser's zoom capabilities, but perhaps there's a way to change all content dimensions with javascript?In firefox, when you press ctrl+, the whole page resizes appropriately, even background images.With this imitation JS zoom, background images would not zoom since there is no scale size numer or anything like that in CSS.It would simply be cool to have a script that resizes everything on the page. That way, you can design highdefinition content that fits a 1280 * 960 browser frame, but can zoom out for smaller resolutions (1024 or 800).

Get An Image's Dimensions / Large Images Always Fail To Load

Oct 29, 2010

I have also Googled this issue plenty of times, but nothing seems to be working 100% and/or the "solution" found is several years old.I have a text field on a webpage where a user enters in a URL to an image and then clicks a button to preview it. I want to restrict the image's size, so if it is larger than 600x450 then it will be automatically resized to those dimensions.The problem I have with this code is that the myImage.onerror event always fires if the image is large. My question is: how do you make the script "wait" for the image to load completely before trying to retrieve the width and height? Or, even better, how do you prevent the image failing to load?

Also, I know how to get the image's dimensions via PHP; however, according to the getimagesize() function's documentation on php.net, the function downloads the image to the server before retrieving the image's width and height, which could be potential trouble if a malicious or ignorant user enters a URL to an excessively large image.

JQuery :: Pass Dimensions To Mouse Functions Instead Of HTML Element?

Mar 9, 2011

I'm developing an image slider. I'd like to be able to trigger functions when the mouse leaves an area, sort of like

$('#someDiv').mouseout or $('#someDiv').mouseleave

except instead of passing the div to the function I have a dimension I'd like to pass to it.

I have box like so[code]...

I have calculated the dimensions from the left of the box to 25% of the width of the box to the right (or 100px from the left of the box) and also calculated the height of the box and top offset. I want to be able to say if the mouse leaves those dimensions, run a function.

Can I pass the dimensions and use mouseout or mouseleave? is this possible without using an HTML element?

JQuery :: Load A Flot Chart Inside A Tab - Invalid Dimensions For Plot

Jun 24, 2009

I am trying to load a jquery chart (Flot) inside the second tab of jQuery tabs. It works fine on the opening tab, but if i bury the chart in any tab, it breaks and throws the js error "Invalid dimensions for plot..."I looked around and the problem might be that because the second tab is hidden at page load, it is breaking something... I dug up a possible jquery fix/plugin called frameReady, which allows for you to load iframes, but I am not sure how to apply it.

[URL]

how I can enable the second tab to show the chart?

Finding Value In Array

Feb 3, 2006

This is just some functionality missing in the Array object that I'd find very useful...

Array.prototype.inArray=function(oObject){
for(var i in this){
if(this[i]===oObject){
return true;
}
}
return false;
}

to use:

var oObj=new Object();
var aArray=[1,oObj,"string"];
aArray.inArray(1); // returns true
aArray.inArray(oObj); // returns true
aArray.inArray("string"); // returns true
aArray.inArray(2); // returns false
