JavaScript - How I Can Make The Scrollbar Stays In A Certian Point???

Hello

I need to do a portfolio of paintings and i found a site similar of what i have in mind.

The site is http://www.pikaboo.be/

It's great because its using javascript only.
I just don't know how to start my reserach for that transitions and moving objects and that stuff

Anyone can give me a few tips on how to start?
I have been looking at jquery and mootools it does some stuff taht it's on this site but the movement of objects and the way as they appear on the screen one by one and all that pretty stuff i have no idea how to search.

Anyone can help me on where to start and how to do something like this?

THank you

I read somewhere (I think from Douglas Crockford) that void is a completely useless operator. What is its actual purpose? Is there anything it's good for?

I see lots of javascript:void(0) hyperlinks all over the place. From what I gather, it just disables the link's default behavior...buy why not just make the href="#" or return false from an onClick handler?

Can anyone enlighten me?

Hey,

I was wondering if it is possible to make an image change whenever an anchorpoint on my page reaches the center or the side of the screen...

Thanks for your help!

ok i need a bit of advice..

I have a webpage and i want to put a section of another website on to my own website..

i have a www.bebo.com profile and i only want to show the comment section on my website..

my profile is www.bebo.com/thegaadiscos

is there a way to only show the comments div of the bebo site on my own website?

What i want is a bit like the face book section of this website
http://www.alexandraburkeofficial.com/

How would this be done does anyone know..

Someone please point me in the right direction. Basically what i'm trying to do is, Post up a nice image map up top of a page with several diff images (all same dimensions), and when the user clicks on one of the images, it loads down in a section below, without reloading the page.

I have drawn a small diagram to show you guys what i'm talking about. So far, all I've found, are scripts that use some sort of lightbox that covers the entire page.

I would like to try to stay away from flash if I can. The main browser, does'nt necessarily have to be one big image with a map, but it would make it look so much better if it looked matched the games menu. I'm trying to replicate a stats game menu, inside my webpage, so ppl can browse just like they do in game.

Example:



What I'm trying to replicate:



When a weapon on this menu is clicked, it loads up on the right, and gives a brief description. I"m just trying to replicate the functionality of this menu really.

So are there any kind of scripts out there that already exist, where I could accomplish this? or how would i go about this.

just need someone to point me in the right direction. Thanks a million

Hi. I am trying to make one small modification to a website. I just want to make an image that, when clicked, scrolls to a certain point. Pleeeeeeaaaaaase help!

This is the javascript that I think controls the scrolling:

var element_y;
var swiffy;
var cur_groupid;
var group_sortable = new Array();
var lightbox;
var content;

window.addEvent('load', function() {
checkScrollerWidth();
checkImages();
});

function checkImages() {
var check_w = window.getSize().x + 500;
var winh = window.getSize().y;

var divs = $$('.single_image_holder');
for(var i=0; i<divs.length; i++) {
if(divs[i].getChildren().length) continue;
if((parseInt($('main_images').getPosition().x) + parseInt(divs[i].get('xpos'))) >= check_w) return;
var img = new Element('img', {
'src': divs[i].get('source')
});
divs[i].adopt(img);
}
}

window.addEvent('resize', function(){
checkScrollerWidth();
});

function checkScrollerWidth() {
if($('scrollbar2') && $('content2') && $('handle2'))
makeScrollbar( $('content2'), $('main_images'), $('scrollbar2'), $('handle2'), true);
}

function makeScrollbar(content,checkContent,scrollbar,handle,horizontal,ignoreMouse){

if(checkContent.getScrollSize().x < scrollbar.getSize().x) {
handle.setStyle('display','none');
return;
}

handle.setStyle('display','block');

var steps = (horizontal?(content.getScrollSize().x - content.getSize().x)content.getScrollSize().y - content.getSize().y))
var slider = new Slider(scrollbar, handle, {
steps: steps,
mode: (horizontal?'horizontal':'vertical'),
onChange: function(step){
var x = (horizontal?step:0);
var y = (horizontal?0:step);
content.scrollTo(x,y);
checkImages();
}
}).set(230);
if( !(ignoreMouse) ){
$$(content, scrollbar).addEvent('mousewheel', function(e){
e = new Event(e).stop();
var step = slider.step - e.wheel * 30;
slider.set(step);
});
}
}

Hi,

So, i'm using the jkpanel dropdown script in my functional prototype to show context-sensitive design notes for our integrators.

it's pretty cool, but i have an implementation question ..

i have many source html files that call the jkpanel script, and each page requires unique content to be loaded into the dropdown panel ..

but, what i see is that the drop-down content html file is hard-coded in the .js file.

in other words, i need to create a .js 'and' and html for every different set of content i want to load into the dropdown panel ..

so, if i have 12 html files to hold the drop down content, i also have to create 12 different versions of the .js file to point to them ..

this seems like overkill ..

is there a way to always point to the same jkpanel.js file in my <head>, but load a different html file to populate its content?

Thanks!

I am allowing my customers to use a rich text editor (wysiwyg) on a jsp page to create snippets of HTML code that can be used to describe their items. When they want to add an image, table or custom tag (something we wrote), they are presented with a properties box created using javascript on the same page just below the editor. Upon clicking 'Insert' button on the properties box, I use javascript to create an HTML string with the tag information and insert the string into the edited page where the cursor was. The problem is that I can't seem to find a reliable way to know where the cursor was.

More information:

I am a C programmer who morphed to a Java programmer who knows some javascript.

The JSP page looks like this:

--------------------------------------------------------------------

Some text and text fields for some basic information


--------------------------------------------------------------------


The javascript wysiwyg editor


--------------------------------------------------------------------
The properties box (changes depending on the type of item being inserted)
--------------------------------------------------------------------

Submit button, etc. for the page (so the information can be persisted)


I have tried:

1. Seven days of searching the web for helpful hints.

2. Using a popup window to get the properties (doesn't work because in IE7, closing the popup also kills the session... I need to use some of the beans on the main window on the popup.)

3. Processing onMouseDown and onKeyDown events storing the element information in a global variable so I could use it later to know the point of insertion. (Has not been reliable and the arrow keys present real problems with where the cursor ends up as that is different from where it was pressed.)

I am frustrated because I don't seem to be gaining on the problem. I suspect it is because I have missed something very simple.

Does anyone have any ideas?

Thanks in advance.

So, here is my question:

Is there some possibility 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 . . .
