Scrolling a div with jQuery

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 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>

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:

http://seekieran.com/2011/03/jquery-scrolling-box/

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.

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. :)

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>

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);
  });
});
