JavaScript - Auto Resizing A Container Div With No Scrollbar

I have a Java script chat,

How would I make a scroll bar for it?

Does any one have any code for that? or do you know what I have to do?

thanks,

So, here is my question:

Is there some possibility with php to put the horizontal scroll bar of the web browser into the center if the "width" of web page are bigger then the "width" of the web browser screen?

So I don't need to scroll to right if I open the page, but the horizontal scroll bar will be positioned in the center.

That code should do the same think like I when I take the scroll bar and put it in the center position, but this should be happen when I load the page automatically.

Or how can I do that?

thanks to all . . .

When Scroll Bar is scrolling, at that time how can we find using js what is the element at the topmost position in that window pane only.

When the user scrolls down, the value of element at the time of that at topmost position


I'm trying to figure out which elements of a document are visible as
the user scrolls the Firefox browser. I haven't written the code yet
but I think I should be able to do it by keeping track of the current
display using the following properties:
window.content.scrollX, window.content.scrollY,
window.content.innerWidth, window.content.innerHeight. -- with these 4
I can determine which part of the document is visible.

Then for each element I can figure out its display position using,
offsetWidth, offsetHeight, offsetTop, offsetLeft. This would entail
traversing the DOM and perculating the offset values down to all the
children.

While this would likely work, it seems inefficient. Do you know of any
other ways to determine which elements are actually on the screen?

Hi, I'm currently working on a JavaScript scrollbar on my website: http://allotrope-dome.net.

I managed to get most of the code working. The only part that isn't working is that users can't click and drag on the scrollbar (click on the "About" section in the navigation bar to get a better idea of what I'm talking about). If any of you could help me out with that, I'd really appreciate it. Thanks!

To see the code, go to http://allotrope-dome.net/about.php and click "View Source."

Hello. Could you guys point me in the right direction. I have a DIV that I woul like to move along with the users vertical scrollbar. So when the user scrolls down on the page the DIV will follow. Where can I find information on how I can do this.

Hi,

I want to let my scrollbar start at a random point when a page opens. I would like the page to load each visit somewhere else and always random like let's say one time more in the middle of the page and the other time more at the end of the page and an other time somewhere else. Someone in php-forums told me that this can by done by Javascript. How do I do that?

Thanx for helping me out.

Best regards,

Thoaren

I am working on a ajax chat system right now and I've ran into a little problem. I have no idea how to go about doing this but I know there has to be a way of doing this because I've seen it done before on other ajax chats I've seen. How do I ago about moving the scrollbar of a div to the bottom so that it shows the last that has been entered into the chat.

If you need me to explain more then just let me know. But basically I'm wanting the scrollbar when it overflows in the window of a div to go and to the bottom when someone enters something new to the chat.

So here is what I have done so far:
- Used FlexCroll (1) to make custom scrollbars on the top image panel
- In the scrollbar - I have used a no-repeat background image that is 17px in width

Problems:
- When loading a vertical scrollbar appears
- The horizontal scrollbar does not go all the way to the end

Here is what I want to do:
- Disable the vertical scrollbar for ONLY this div (this same script is used for another vertical scrollbar - http://www.hannahdesign.co.nz/client/summary)
- Make the horizontal scrollbar limited to 17px or another set width.

I have included both my CSS and the uncompressed JS.


(1) - FlexCroll - http://www.hesido.com/web.php?page=customscrollbar

I am using this code to control scrolling of 2 divs at the same time, but i want to be able control 3 (or more) divs at the same time.. what am i missing?

JS in head:
<script type="text/javascript">
function scrollDiv(controllingElement, controlledElementID)
{
var controlledElement = document.getElementById(controlledElementID);
controlledElement.scrollTop = controllingElement.scrollTop;
controlledElement.scrollLeft = controllingElement.scrollLeft;
}
</script>


JS in body applied to parent / controlling div:
<div id="master" onscroll="scrollDiv(this,'top');" > ...</div>


Names of the 2 divs controlled by "master":
<div id="top" >...</div>
<div id="bottom" >...</div>

Appending to a div (id=right) over time. There is a scrollbar on the right side. At some point, the scrollbar appears but the user has to manually move the scrollbar to the bottom to see the newest appends.

Googled and found a number of "solutions" that I can't get to work. The ideal would be to always have the scrollbar move to the bottom after each append.

Code:

 #right {
    background-color: #FF0;
    width: 150px;
    height: 300px;
    float: right;
    overflow : auto;
  }

$("#right").append("<p>something important here");

Hi all,

I am currently building a PHP based site and need some help with a Javascript problem I have. I am relatively new to PHP and have not started on learning any Javascript yet!

I copied some Javascript that I found on 'http://www.javascriptkit.com/script/script2/htmltooltip.shtml' so that I could use tooltips. It works well and I have edited the CSS a bit to suit my needs. However I still have one problem which I can't solve as I believe it is the Javascript that is causing the problem.

My page (which has the tooltips and code on) has vertical and horizontal scrollbars that only allow you to move a tiny bit. They are unnecessary and even when I remove almost all the elements of the page, the scrollbars remain. When I remove the line '<script type="text/javascript" src="scripts/jquery-1.2.2.pack.js"></script>' from my code, the scrollbars dissappear, but this line is vital for the tooltips to function.

This script is available for download at the given URL above (it is in the center of the page called 'jquery-1.2.2.pack.js').

Please could somebody take a look and see if they can help, any advice appreciated.

Thanks Very Much
Dan

Ok, told you I'd be asking lots of questions ...

Code:

	<div id="resizetest" style="width:200px;height:200px;border:2px solid blue">
		<div style="background:#000033">
			<a href="#" style="float:right;background:#ffffff" onclick='document.getElementById("resizetest").height="50";'>_</a>
			&nbsp;		
		</div>	
		This is a resize test
	</div>

Why doesn't this resize? I've looked at examples, and I don't see what's wrong.

Hi All,

I have a javascript scrollbar in the middle of the webpage, with two images as arrow at both end. Onclick of up and down arrow images the inside content moves up and down respectively. All works fine. What I need is, when I scroll down the down arrow should be disabled or invisible (as there is nothing to scrolldown) and same way when the content is at the top, the up arrow should be disabled or invisible. Please help...
