View 1 RepliesAll my font-sizes are set as relative sizes in CSS (large, medium, small,
x-small, etc). Let's say something is set in CSS to be xx-large, but a
visually impaired user wants it displayed even bigger. Can a script
determine an element's absolute size, *as it is being rendered by the
browser*, and then increment the element's font-size in absolute terms?
I'm attempting to make a web page that adapts to the size of your browser size when it maximized. Because I'm only 15 I'm not such a great programmer or coder. I've done my best with the resources I have though (Fluent in Lua and a natural ability to pick languages syntax up quickly)
Here is what I have so far, it doesn't work and it is starting to puzzle me. As it seems correct as I look at it. I'm sorry if this question show my ignorance. I try my best to hide it.
Some of it is Copy pasted from sources on Google. But only for educational purposes, I learn off reading, examining and testing out snippets.
I'm basically trying to get the max size of the window and resize the div accordingly.
I am using javascript to load and parse a big xml file (around 1 mb) save some values to an array and draw a picture using google Flot. Unfortunately, this causes the browser to crash! Is there a way to clear the memory of the browser?

However the problem is that once the tabs/iframes are removed the browser does not release the memory. This happens both in IE8 and FireFox. So over a period of time the memory consumed by the browsers are huge because of the creation and deletion of new tabs/iframes and the application slows down. Is there a way to make the browser release memory when an iframe is removed.
How can I change my text or font size when the user changes the browser size. Example: When the browser is maximized, the font goes to normal, when the browser window decreased, the font size is reduce.

When I use mouse wheel in Firefox to scroll contents of the DIV, memory usage in Firefox goes through the roof. Code above is a fully working page, if anyone would like to see what's up, just load it up, and start moving your mouse wheel in the area with text. You don't actually have to scroll the text, just moving the wheel back and forth in that DIV will do. Memory usage will start going up quite fast, and after you stop moving the wheel, it will finally come down a bit after a short while. I've highlighted in red the line where mousewheel event is registered for Firefox. I'm not sure if it's really a problem, but since Opera and IE don't have any strange memory usage, and Firefox does, maybe I did something wrong. In everyday use it shouldn't matter [don't expect to have kilometers of content to scroll], but anyway, it is a bit unsettling.
Well after playing around a little I have created a solution that works although it appears a little chunky. The problem was finding the browser size to use the width as a variable for size conditional aspects to a site. Code:

Code:

I am working on Javascript code that gets the size of the browser viewport. My code works perfecty if the page has content. But my code does not work at all if the page has no content. Try the code examples above to see what I am talking about. How can I make it work regardless of whether or not the page has content?
I'm curious if it is possible to detect the browsers default font and
size? Most of the posts on this topic predate Windows XP, IE 5.5,
Mozilla Firefox, et al.
I've searched up and down the DOM properties, looped through most
objects and collections alerting properties and values, and I can't
find anything. This leads me to believe it is not possible to detect
the browsers default font settings.
I'm using a little javascript to help my site's design to fit the visitor's entire browser window.
Everything works great apart from one problem. If a visitor first loads the page and the browser isn't maximised, the page loads correctly BUT if the visitor then proceeds to maximize the browser, the page is still set for the minimised browser. This condition stays until the visitor goes to another section of the site or refreshes the page. When this happens, the page again loads correctly.
I would like to force a page reload whenever the browser is minimizedmaximized or is in any other way changed size. How can I do this?
I want to resize the div based on browser size, I mean when first it load I want it to fit on browser window and no scrolling bars should be appear and when I resize the browser size by dragging, it should be fix on that size.for example visit this link:I WANT THE SAME BEHAVIOR (SIZE BASED ON BROWSER) BUT USING JQUERY.

View 12 Replies View RelatedDoes jquery have an event defined for when the user changes the size of his browser window? I couldn't find one, but sometimes I don't see the forest for the trees.
View 2 Replies View RelatedI have been trying all sorts of things, but falling short... I'm trying to set up a way to detect a user's browser size and then call a specific background image accordingly...
say (for example) that BKGD1.jpg is for users who have browsers that are 1280x1024 and higher; BKGD2.jpg is for users who have browsers that are smaller than 1280x1024...
i'm even open to an option that only displays a background image if the browser is (as in the example above) 1280x1024, and just a background color if the browser is smaller than that.
The problem:
I have an XHTML STRICT page which has some event listeners attached for onload and resize. I'm doing a bit of Javascript DHTML on these events. When a user changes the browser font size, the javascipt function needs to run. Although the TOPMENU DIV gets resized when the font changes size, its not a page resize so the function doesn't get run. I fixed this in IE6 by using a second function which is run onload and sets an event on the div object in the page after its been defined.
Problem is this doesn't work in Firefox.
Mozilla DOM reference says there is no resize event on a DIV so is there a work around to make it work in FIREFOX? i.e. can I force a resize event to happen on a div in firefox or is there some other event I can trap when a user changes the browser font size?
here's my js code: topmenu is what I'm trying to trap the resize event from.
this code is loaded in the head of the page.
function maindiv(){
estartup=document.getElementById("startup");
econtain=document.getElementById("contain");
emain=document.getElementById("main");
etopmenu=document.getElementById("topmenu");
emaincontent=document.getElementById("maincontent");
nopx = document.childNodes ? 'px' : 0;
contw = document.body.clientWidth - 80;
conth = document.body.clientHeight - 80;
if (contw < 0) { contw = 0;}
if (conth < 0) { conth = 0;}
econtain.style.width = contw+nopx;
econtain.style.height = conth+nopx;
if (conth >= 100 + etopmenu.clientHeight) {
emain.style.height = (conth - etopmenu.clientHeight - 100 )+nopx;
}
if (contw >= 172) {
emaincontent.style.width = (contw - 172 )+nopx;
}
estartup.style.visibility = 'hidden'
}
function fsize() {
etm=document.getElementById("topmenu");
if (typeof window.addEventListener != 'undefined')
{
etm.addEventListener("resize", maindiv, false);
}
else if (typeof document.addEventListener != 'undefined')
{
etm.addEventListener("resize", maindiv, false);
}
else if (typeof window.attachEvent != 'undefined')
{
etm.attachEvent("onresize", maindiv);}
else
{
window.alert('Failed to attach an Event Listener
Please Report');
}
}
if (typeof window.addEventListener != 'undefined')
{
window.addEventListener("load", maindiv, false);
window.addEventListener("load", fsize, false);
window.addEventListener("resize", maindiv, false);
}
else if (typeof document.addEventListener != 'undefined')
{
document.addEventListener("load", maindiv, false);
document.addEventListener("load", fsize, false);
document.addEventListener("resize", maindiv, false);
}
else if (typeof window.attachEvent != 'undefined')
{
window.attachEvent("onload", maindiv);
window.attachEvent("onload", fsize);
window.attachEvent("onresize", maindiv);
}
else
{
window.alert('Failed to attach an Event Listener

}
Any clues?
I build a website with Typo3 and it works fine, except for the text size in Internet Explorer (and Opera). I tried anything from changing the CSS templates (excluding them) to changing px to pt to em and so. Finally, I think i need a Javascript that detects the browser and if it is Internet Explorer (or Opera) the textsize should be reduce by 1. It therfore should be the same like manually clicking in IE on View->text size -> smaller (default is medium).
My javascript (I just use Javascript for this single purpose) does not work/it does not do anything:
function resizeText(){ if (browserName=="Microsoft Internet Explorer") {document.body.style.fontSize = parseFloat (document.body.style.fontSize) -1 ;}}
I have a background image that auto-resizes based on browser window / screen resolution. I want my top header menu, which requires links, to act in the same way and be in roughly the same position/size based on browser window. Is this possible? In the sample below, the image is just part of the background image to give you an idea of the look I am trying to duplicate.Is there a Javascript out there that will help me or will I be stuck having to rework my design?
View 6 Replies View RelatedI have an upload file operation in the web application. UploadForm.jsp
is the form, and UploadAction.jsp is the form processing. The web server is
Websphere.
//UploadForm.jsp
<FORM NAME="InputForm" ACTION="UploadAction.jsp" METHOD="POST"
enctype=multipart/form-data>
<input type="file" name="fileName">
//etc ...
</FORM>
After I deploy the application to the web server, if I upload a small
file size, it is fine.
But if I upload a huge file size more than 10MB, then it cannot even go
to UploadAction.jsp.
After 30 seconds, it has error "The page cannot be displayed" shown on
the web browser.
It cannot even go to UploadAction.jsp. But both UploadForm.jsp and
UnploadAction.jsp are in the same machine.
Interestingly, if I test in local machine, I can upload any file size
without problem. I don't have any hints now. any ideas?
where da boss wants our a large piece of our site to be fully dynamic and integrated on any screen size. This means changing font on size. Well I cam up with a solution, figured if no one has one better, then i'll share

View 2 Replies View RelatedI developed a web application and it is working fine, except for one issue. The application includes uploading files from a JSP to my servlet, and the issue is that i would like to have a limit for the uploaded files on the client side (before actually uploading it).
I investigated alot and found some ways like changing my JSPs to PHPs, which is not feasable for my application. I would also like to add that using the Flash component ("<object>") for uploading is not feasable also at this time. Using ActiveX does not work also (for some security issues in javascript, it can not access the system information, also ActiveX works only on IE).
I would like to add that I have my application running on Oracle application Server, JSPs for displaying the forms, MultiPart Java API for getting the form input values and files to my servlet and everything is developed in JAVA.
Either by limiting the file size or the limiting the whole request size sent to the servlet.

I'd have thought this would be easy but I've been looking for hours and all I can find is info on getting the viewport size, which is normally useful but not in my situation.
In this case I need the actual browser size, including the scrollbars, toolbars, status bars etc. to get an idea of browsers which aren't maximised/full screen and how big they are, and to calculate the amount of the screen taken up by toolbars etc too.
I need help with this code. its a counter.
var count= 0
function onm() {
atextbox.value=ffee
count++
setTimeout(onm(),100)
}
And in the body:
<body onload="onm()">
<input type="text" value="0" name="atextbox">
</body>
I get always an error: Out of memory
