I am attempting to create a div in a container within a container which is scrollable with up and down arrows in jQuery.
The only thing I can find which I wish to use was http://www.dynamicdrive.com/dynamicindex11/scrollc2.htm
I would've started attempting to convert that to jQuery, however it apepars to use tags like ilayer and layer. I would like to use more standard tags if possible.
Any pointers in the right direction would be highly appreciated.
This question is related to
javascript
jquery
html
css
I don't know if this is exactly what you want, but did you know you can use the CSS overflow property to create scrollbars?
CSS:
div.box{
width: 200px;
height: 200px;
overflow: scroll;
}
HTML:
<div class="box">
All your text content...
</div>
I was looking for this same answer and I couldn't find anything that did exactly what I wanted so I created my own and posted it here:

Working Demo: http://jsbin.com/azoji3
Here is the important code:
function ScrollDown(){
//var topVal = $('.up').parents(".container").find(".content").css("top").replace(/[^-\d\.]/g, '');
var topVal = $(".content").css("top").replace(/[^-\d\.]/g, '');
topVal = parseInt(topVal);
console.log($(".content").height()+ " " + topVal);
if(Math.abs(topVal) < ($(".content").height() - $(".container").height() + 60)){ //This is to limit the bottom of the scrolling - add extra to compensate for issues
$('.up').parents(".container").find(".content").stop().animate({"top":topVal - 20 + 'px'},'slow');
if (mouseisdown)
setTimeout(ScrollDown, 400);
}
Recursion to make it happen:
$('.dn').mousedown(function(event) {
mouseisdown = true;
ScrollDown();
}).mouseup(function(event) {
mouseisdown = false;
});
Thanks to Jonathan Sampson for some code to start but it didn't work initially so I have heavily modified it. Any suggestions to improve it would be great here in either the comments or comments on the blog.
This worked for me:
<html>
<head>
<title>scroll</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js" type="text/javascript"></script>
</head>
<body>
<style>
div.container {
overflow:hidden;
width:200px;
height:200px;
}
div.content {
position:relative;
width:200px;
height:200px;
overflow:hidden;
top:0;
}
</style>
<div class="container">
<p>
<a href="javascript:up();"><img src="/images/img_flecha_left.png" class="up" /></a>
<a href="javascript:down();"><img src="/images/img_flecha_left.png" class="down" /></a>
</p>
<div class="content">
<p>Hello World</p><p>Hello World</p>
<p>Hello World</p>
<p>Hello World</p>
<p>Hello World</p>
<p>Hello World</p>
<p>Hello World</p>
<p>Hello World</p>
<p>Hello World</p>
</div>
</div>
<script>
function up() {
var topVal = $(".content").css("top"); //alert(topVal);
var val=parseInt(topVal.replace("px",""));
val=val-20;
$(".content").css("top", val+"px");
}
function down() {
var topVal = $(".content").css("top"); //alert(topVal);
var val=parseInt(topVal.replace("px",""));
val=val+20;
$(".content").css("top", val+"px");
}
</script>
</body>
</html>
There's a plug-in for this if you don't want to write a bare-bones implementation yourself. It's called "scrollTo" (link). It allows you to perform programmed scrolling to certain points, or use values like -= 10px for continuous scrolling.
Relatively-position your content div within a parent div having overflow:hidden. Make your up/down arrows move the top value of the content div. The following jQuery is untested. Let me know if you require any further assistance with it as a concept.
div.container {
overflow:hidden;
width:200px;
height:200px;
}
div.content {
position:relative;
top:0;
}
<div class="container">
<p>
<a href="enablejs.html" class="up">Up</a> /
<a href="enablejs.html" class="dn">Down</a>
</p>
<div class="content">
<p>Hello World</p>
</div>
</div>
$(function(){
$(".container a.up").bind("click", function(){
var topVal = $(this).parents(".container").find(".content").css("top");
$(this).parents(".container").find(".content").css("top", topVal-10);
});
$(".container a.dn").bind("click", function(){
var topVal = $(this).parents(".container").find(".content").css("top");
$(this).parents(".container").find(".content").css("top", topVal+10);
});
});
An excellent plug-in is jscrollpane
I know this is ages old, but upon searching for something similar this morning, and reading up on Atømix' response (as this is what we're aiming on achieving), I found this: http://www.switchonthecode.com/tutorials/using-jquery-slider-to-scroll-a-div.
Just putting that there in case anyone else needs a solution. :)
