ho trovato questa guida per inserire questa scrollbar personalizzata: http://livepipe.net/control/scrollbar
allora ho fatto un documento di prova cosi:
codice:
<html>
<head>
<script>
var scrollbar = new Control.ScrollBar('scrollbar_content','scrollbar_track');
$('scroll_down_50').observe('click',function(event){
scrollbar.scrollBy(-50);
event.stop();
});
$('scroll_up_50').observe('click',function(event){
scrollbar.scrollBy(50);
event.stop();
});
$('scroll_top').observe('click',function(event){
scrollbar.scrollTo('top');
event.stop();
});
$('scroll_bottom').observe('click',function(event){
//to animate a scroll operation you can pass true
//or a callback that will be called when scrolling is complete
scrollbar.scrollTo('bottom',function(){
if(typeof(console) != "undefined")
console.log('Finished scrolling to bottom.');
});
event.stop();
});
$('scroll_second').observe('click',function(event){
//you can pass a number or element to scroll to
//if you pass an element, it will be centered, unless it is
//near the bottom of the container
scrollbar.scrollTo($('second_subhead'));
event.stop();
});
$('scroll_third').observe('click',function(event){
//passing true will animate the scroll
scrollbar.scrollTo($('third_subhead'),true);
event.stop();
});
$('scroll_insert').observe('click',function(event){
$('scrollbar_content').insert('<p>Inserted: ' + $('repeat').innerHTML + '</p>');
//you only need to call this if ajax or dom operations modify the layout
//this is automatically called when the window resizes
scrollbar.recalculateLayout();
event.stop();
});
</script>
<style>
#scrollbar_container {
position:relative;
width:500px;
}
#scrollbar_track {
position:absolute;
top:0;
rightright:0;
height:100%;
width:10px;
background-color:transparent;
cursor:move;
}
#scrollbar_handle {
width:10px;
background-color:#5c92e7;
cursor:move;
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
opacity:0.9;
-moz-opacity:0.9;
}
#scrollbar_content {
overflow:hidden;
width:485px;
height:250px;
}
</style>
</head>
<body>
<div id="scrollbar_container">
<div id="scrollbar_track"><div id="scrollbar_handle"></div></div>
<div id="scrollbar_content">prova

purtroppo il risultato è un documento con scritto

fino a che non spariscono le scritte senza scrollbar... c'è qualcuno che mi può aiutare a capire cosa ho sbagliato???
grazie
