i am using jquery to detect picture width and height in a page. if the size exceeds a specified value, then a maximum size will be assigned to the <img > attribute.
this jquery is run with $(window).load, because when $(document).ready the pictures may not be loaded and the script may fail
this theory is good. however, if the internet speed is slow, or the picture link is dead, user would have to wait for a long long time before the jquery executes.
is there any way to do the resizing job wisely? for example, resize each picture once each of the pictures is loaded?
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.
I've written a small plugin to serve as a feature rotator and am having one strange problem.You can see some demos of the plugin and documentation here:
http://pbskids.org/pbskidswidgets/carousel.html.The plugin does a number of things that involve reading the width and height of DOM elements and using them to set the width and height of other elements. The problem is that sometimes in Firefox and Safari, when the page loads, the widths and heights of panels in the carousel are fracked.
Reload the page and the problem's fixed. In Safari, I can't get it to happen again on many reloads. In Firefox, though, if I reload repeatedly, I can get the problem to happen again: maybe once every seven or eight times.It looks like something's happening with page loading, but I'm at a loss to diagnose it further: is the script firing before the elements have fully loaded sometimes, and then works on subsequent tries because those elements are in the cache? Also: I've never seen this error in any of the IE versions.
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 am building a web application that a part of it will create ID cards. I am wondering if there is a way though JavaScript (or maybe flash) to detect if there is a connected camera and then take the picture by previewing it on the actual web application and then upload it to a DB using php. Does anyone know of anything like that? I have searched the forums but did not find anything similar.
Is there any way to detect the width of the window in which a page is displayed? I know how to detect the screen width, but that only helps if the page is always maximized.
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?
Is there a way to detect with javascript the scrolling bar with of the browser?
My problem is that the the following script assing to the pos variable the browser window size but only internet explorer substracts the scrolling bar with from the result.
<script language="JavaScript" type="text/JavaScript"> <!-- var pos; if (window.innerWidth) { pos =window.innerWidth; } else if (document.documentElement && document.documentElement.clientWidth) { pos= document.documentElement.clientWidth; } else if (document.body) { pos= document.body.clientWidth; } //--> </script>
At least i want to ask if there is a script that return exactly the width of the browser's window that i have to output any text or graphic?
I know 800x600 screens occupy a shrinking part of Web surfers, but I want to accommodate them by offering an alternate style sheet where my site pages don't break when someone from this smaller group visits. Yes, there are examples of how to do this on the Web, but I have one more requirement and don't know how to code it. Not only do my pages break on 800x600, they also break if the browser widow is sized smaller on a 1024x768 screen. (I'm studying css that will dynamically respond to this but I'm not there yet.) Do I just need an appropriate if/or statement to deliver different style sheets? Is there even a JS that detects browser window changes?
I am very new to javascript, it is on my list of things to learn... but I have a wide range of other traditional programming languages so I understand functions, etc
however in the mean time I am looking for a way to detect the height of a specific div.
My goal is that I have a div that is set to overflow: auto ,
If the content of the div goes beyond its set height, I would like to make a div visible. So basicly I need to get the height of a div element, and compair it to a pixel number.
To go a step beyond, it would be cool to make the div that is visible when there is scrolling, to disapear once you got to the bottom of the div.
I've been looking around all day for a script that would detect the height of one div (can't be predefined because of dynamic text content), and set a second div as that same height.
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.
Is there a way to detect with javascript the height and width of a browser window that's open? Much the opposite of a pop-up where you define the height and width I guess you could say - anyone know if this is easily possible?
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.
