Php Get Image Height Without The Use Of Input Box?
Aug 15, 2007
I'm looking around and it looks like there is lots of good info on pulling a var from php and using it in javascript, but no the other way around. All the info I can find says to just use hidden input boxes to hold the data, then post them with a submit button. But I have like 40 images, and I want to store their 'left' 'top' width' height'. Thats a lot of hidden input boxes to write (160+). It would be nice not to have those html'd into my script. Is there anyway to get the image height and set it as php data without a input box?
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 relatively new to coding in javascript, so I'm hoping that some kind souls could help me out! I'm trying to make an animated image height changer (example: changing an image's height from 50px to 500px). I'm working on a new web site using HTML5 and want to add some Flash-like animation to my page using javascript and <canvas>.The animation would only need to "play" one time once the web page has loaded. No looping is required and no user interaction (ie mouseovers, etc) is needed.
[code]The image's height is 376px. So once the content goes after 376px, the blue bgcolor alternate takes over. But what i want is, once the content crosses the 376px height, the background image should dynamically stretch and not repeat.If this is not possible please do tell me how to increase the height of image in <img> using DOM methods.Again this should increase when the image's original height becomes greater than 376px
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 am trying to do something with a sprite image, which is changing the height of it when an action button is clicked. The sprite image is 602x5485px. For clarity here's the link [url] and here's the image [url] and when the "Run sequence" button is clicked the height of the background image is supposed to change (each image is 602x399) so I need to add another 399px to move to the next one. The sequence will run till the last picture and then come back so that it gives a kind of movie animation (so in brief adding 399px till it reaches the last pic and then removing 399px till it gets to the first one).
Here's the html page without the script:
HTML Code:
And here's the css just for the sprite image:
Code:
Ok let's get to the script now (which won't be an external file but within the html page, I separated it temporarily for the sake of clarity). What the script should do, I think, is to get the background image which is in the css, and change the css background position adding - as said - 399px. When it gets to the end, remove 399px till it gets to the first image.
So in practice here are my last (believe me of many!) attempt:
Code:
I am not sure whether this is correct but I am not quite sure how to continue. The thing is, I want to change the height of the background image as said and the above should change at least one image but it doesnt work. If somebody has the patience to talk me through that (I am a beginner so I would like to attempt to build the code myself.
I have an image that I set to have a width of 100%. I want its height to be no greater than the visible height of the browser web-page area. This could distort the image, but thats OK. To makes things difficult, the image is in a div, and I want the div to be higher than the visible area. So I can't just set the div to height of 100%, and then within that set the image to a height of 100%. I know there is a javascript way of getting the height of the entire screen (screen.height) but that includes the extra areas of the browser such as toolbars etc. I know there is a 'offsetHeight' attribute, but I think I would have to use that on the BODY tag, and the BODY of the page could be several screens in height. So is there a solution to this? If there isn't then can I detect the aspect ratio of the screen?
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..

Can I get Images to resize to window height when called from an 'a' link created in a cell of 'insertRow'.
Something like this Code: var additemlink=top.frames['register'].document.createElement('a'); additemlink.setAttribute('id','itemlink'+count); additemlink.setAttribute('href','zanfeld/p'+code+'.jpg'); additemlink.setAttribute('target','display'); additemlink.setAttribute('title','Review this item then click your back button to return'); additemlink.className='itemlink'; additemlink.appendChild(document.createTextNode(item)); additemlink.onclick=function(){resize(this, 100, 100);}; additem.appendChild(additemlink);
I've seen a lot of inline scripting for this but no dynamic unobtrusive 'resize' image examples are to be found.
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.
Using a UI dialog I'd like to load in 10 or so images. Each would be unique and after you click on one the following needs to happen:
1. Image appears on the parent page in a specified ID.
2. A "hidden" field is updated so that when the user submits the db is updated with their selection.
3. Dialog closes automatically.
That's it. Basically it would work similar to "datepicker".I'm using the latest 1.4 and ui and been making great progress as learning basics. I need to do the above and it seems like such a no brainier and or it should already exist but after 2 days of searching and trial and error...
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 have a hidden popup that I populate with content and it dynamically expands to the size of the content. I then show the popup. When a user clicks on another link, it populates the popup with longer or shorter content. When the content is SHORTER, it seems to show the background image that I'm using expanding to the height of the previous size of the popup. I've tried setting the height manually with JS, no luck. This only happens on IE6.
I am working on a UI that, when you click on a menu option, a div opens and show three divs inside. These divs all have different heights. The heights are based on the divs content.The problem I'm having is... how do I measure what the divs height should be? IE, how do I grab the height for a div BEFORE it has had any style applied to it.
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
I am in need of a JS script that matches the "li" height with the un-defined height of a absolute positioned block? Sort of like a matching columns script - is this possible? It's for IE6! Oh ya, and it's dynamic un-defined height. I only want it to match the height on hover. Here is a little test page I put together.[code]
how to adjust the iframe height by itself if my html height increases. My html code includes a facebook comment at the bottom of my page and the comment will show making it expand the height once users post comments. On the other hand, I'm using a CMS that have its own iframe. I've tried many solutions that can be found on the web but none works. It only can work if I don't put in CMS. Is it possible to adjust the iframe height using CMS or there is no way?
capturing just the file name rather than the entire path of the SRC on my input type="image". Basically when I hover over an image, the Default Image should change to the image being hovered on. Here is my code, can't quite get it to work. Sorry I'm very new to JavaScript
<html> <head> <script language = "Javascript"> function ChangeDefault(src) { //document.frmMain.DefaultImage.src = src <--Doesn't work at all alert(src) //<---Displays the entire file path, want just file name [Code]...
