Specifically, assume I have a div tag of absolute dimensions. I need
to figure out, first, whether or not the text inside the div tag is
partially hidden by the overflow setting, and if so, what the hidden
text is.
Is this even possible? Obviously, the rendering engine in the browser
"knows" this information, but is it accessible through Javascript?
i have a tetxtarea, with the style overflow:hidden, and a long text.
because of the overflow, user does not see the whole text but a part.
is there, in an IE browser, a mode to recovery the effective text
than user see?
I have a pop-up window system on my site that shows an absolutely-positioned div over the entire page as a "pop up" of sorts when someone clicks a link. I use this simple line of Javascript to disable page scrolling when a "pop up" box is opened by a user:
document.documentElement.style.overflow = document.body.style.overflow = 'hidden';
The problem is that when a user is scrolled down on a page and clicks a link to bring up one of my pop up boxes, when the overflow is set to 'hidden' to disable scrolling, the page "jolts" back up to the top (similar as to what would happen if someone clicked an <a> element with href="#" ). However, the links are not actually links, but span tags that are programmed with JS to trigger the scrollbar to be disabled when clicked, so that is not the culprit here. I've narrowed the problem down to that one line of code which I posted earlier. Apparently, setting the documentElement overflow style to 'hidden' scrolls the user to the top of the page automatically along with "disabling" the scroll bar on the page.
I am wondering if there is a way to prevent this jolting to the top of the page each time that JS code is triggered. I don't want users to have to scroll back down to where they were each time they open a pop up dialogue box on my site, as this would be detrimental for usability purposes.
In the top right of the page is a JavaScript (Prototype) Carousel that scrolls through images when you click the arrows. It works properly in all browsers except IE 6 & 7 (it does work properly in IE 8) with my primary concern being IE 7. When you click on the right arrow to scroll to the next image it scrolls properly but the entire strip of images is displayed and it sites on top of the page's content.I've tried all of the overflow:hidden hacks I could find so.
View 1 Replies View RelatedI'm currently building a website that has a flash fullscreen popup at the beginning. The flash popup loads fullscreen, therefor I've set overflow-y to hidden. As soon as the flash popup is done, it removes the div it the flash is in using javascript, but I can't figure out how to put the overflow-y to visible.
I'm assuming I need to build a Javascript function to show overflow-y visible, and then need to call to that function from the flash file. I just can't figure out how to build the javascript function since I suck at javascript.
All the CSS is in the original file, so not in an external stylesheet, this needs to stay that way because I have to implement the code in to several different web sites.
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
the css line
body { overflow:hidden }
doesn't work with the W3C standards
is there another way I can get rid of the scroll-bars on the body of the document, and still be W3C compliant?
I've been trying to implement a smooth scrolling animation in my page, which works fine in firefox and IE8 (haven't tested any older versions yet). But doesn't seem to work in google chrome (and probably safari either I guess). I have 4 divs on my page, positioned absolutely 2 by 2, only one div should be visible at a time, so the body has gotten an overflow:hidden. When an anchor-link to one of those divs is clicked the javascript gets its position,then scrolls towards it. etting the position works, but the scrolling does not work in chrome.
Now, when I remove 'overflow: hidden' from the body element, the scrolling does work in chrome, but of course adds the scrollbars which I don't want.

I'm looking for some javascript that'll toggle hidden content. As I'm not experienced in this, I want something which is cross-browser reliable - and I'm having trouble finding something suitable. Jquery has been suggested as an option... and I found something which appeared to do the job, apart from not validating as it uses a span to include the toggled content - which is a problem as I need to included block level stuff to be hidden. Also, it came as two buttons - show and hide - and I'd prefer a single button, or preferably a normal html link.
View 6 Replies View RelatedI am trying to get a simple set of Javascript tabs to work properly. I have just two tabs and I want to set up the script to have the second tab automatically hidden prior to reading the javascript code because right now it shows the contents of both tabs when the page is loading and then the second tab disappears after all the script has loaded.
I have the jquery script linked to on the page and here is the way my script looks to run the tabs:

I want to add something like style="visibility:hidden;" to the DIV that isn't shown on page load and have it added and removed as necessary when users click on the tabs. So basically I would like the generated code to look like this:
Code:
'When my form is submitted, I have onsubmit pointed to the following
code snippet. But, the button is not actually set to disabled and the
style.visibility changes are not made for several seconds. It appears
that it goes into validateForm and doing the rest of this snippet
before the browser makes the changes.
How can I get the browser to immediately make the UI change?
function submitForm(servleturl) {
var submitbuttonelem = document.getElementById("submit");
submitbuttonelem.disabled = true;
document.getElementById("modgradeform").style.visibility="hidden";
var mydiv = document.getElementById("contentarea");
mydiv.innerHTML = "Validating the form.";
mydiv.style.visibility="visible";
var ret = validateForm();
I need to check if attachEvent was done to an element. The problem is that attachEvent does not save this information anywhere.

I am unsure what is going on with my website? I had flash on it, and I have removed the flash and installed javascript. Everything is installed correctly from what I can see, when I go to the view page button on Dreamweaver the images rotate.

Take a look at my testing website: [url]
You'll find the following javascript in the source code:
Now this all works...well, sorta.
The DIV elements specified are hidden when the page is first loaded.
These DIV elements then re-appear (as programmed above) when the mouse pointer is hovered over them.
These DIV elements are listed on the right-hand side of the test webiste.
They contain the Google Ad's you will see listed along the right-hand side of the website.
However, you were not suppose to see the Google Ad's when the website first loads up.
The DIV elements are initially hidden, but the Google Ad's contained in the DIV elements are always visible!
I want the Google Ad's to only appear if a mouse pointer happens to hover over them ( a little test of mine.)
I don't get it...the DIV elements disappears when appropriate, why not their contents: the Adsense?
I have a class hidden by default at the document ready state. I use the show() function when its parent has been clicked and I want to be able to apply a click function to this newly visible element - when I write it I am finding that it is overriding the initial hide(). How do I work around this? I should say that this element is just a bit of text that says "close x" and will be used to "close" its parent div down...
View 1 Replies View RelatedMy design involves two "layers". On the first layer, I have a circle, with some links in the middle. This is just a div with a background image, and some text in the center. Then I have another circle, same size and shape, on top of the first one, covering it up. This circle just has a one or two word title on it. When a user hovers over the title with their mouse, I want that div to disappear, showing the links underneath it. When you mouse out, the circle with the title should show back up.
Here is the basic HTML:
[Code]...
So what happens, is if you mouse over, the circle fades away just fine. But if you move your mouse at all again, even the slightest bit, the event is triggered again. So the title fades in and then out again real quick. Even if you actually mouse completely out of the CircleTitle div, it still triggers one last time instead of just fading in.
Because mouseenter keeps track of the mouse being over that element, and then that div disappears, it's probably causing some problems. But I don't know any other way to get this to work! If someone has some ideas,
