I'd like to trigger scrolling of a div with overflowing content by scrolling anywhere on the page, not just by moving the mouse and clicking within the div. Also, i'd like to hide the div's scrollbar such that only the page's scrollbar is visible.

Preferably the solution would be CSS-based but a JS solution would work too.

here's my jsfiddle that demonstrates the problem: /

I'd copy the code here but there I put a bunch of filler text to trigger the scrollbars.

For you reference though, the name of the internal div I'd like to scroll on scrolling the page has an id="scrollMeToo".

• javascript
• css
• scroll
• scrollbar
• overflow

• That is not a simple thing to implement. Do you have any javascript experience? – laymanje Commented May 16, 2012 at 20:58
• @laymanje yes, i have javascript experience. let me try perdickss's solution below to see if that solves the problem... – tim peterson Commented May 16, 2012 at 21:58

$(window).bind('mousewheel DOMMouseScroll', function(e){

    var delta = evt.detail? evt.detail*(-120) : evt.wheelDelta;
    if(delta < 0) {

This should do what you need, if you don't want the document to scroll, just change the return true; to return false;.

Non-jQuery method:

var curScroll = 0;

function controlScroll (e) {
    var evt = window.event || e;
    var delta = evt.detail? evt.detail*(-120) : evt.wheelDelta;
    if(delta < 0) {
        //scroll down
        curScroll += 10;
    }
    else {
        //scroll up
        curScroll -= 10;
    }
    document.getElementById('scrollMeToo').scrollTop = curScroll;
}; 

if (document.attachEvent) {//if IE (and Opera depending on user setting)
    document.attachEvent("onmousewheel", controlScroll)
        
}
else if (document.addEventListener) { //WC3 browsers
    document.addEventListener("mousewheel", controlScroll, false)
}

#scrollMeToo {
    height: 200px;
    width:150px;
    overflow: auto;
    position: relative;
    overflow-y: hidden;
}

In order to change the scrolling speed, simply modify this block to suit your needs:

if(delta < 0) {
    //scroll down
    curScroll += 10;
}
else {
    //scroll up
    curScroll -= 10;
}

Just change the 10 values to whatever you need.

Update:

var curScroll = 0;

$(window).on('mousewheel DOMMouseScroll', 'body', function(e){
    var evt = window.event || e;
    var delta = evt.detail? evt.detail*(-120) : evt.wheelDelta;
    var loc = $('#scrollMeToo').scrollTop() + $('#scrollMeToo').innerHeight();
    var height = $('#scrollMeToo')[0].scrollHeight - 10;
    var height2 = $('#scrollMeToo')[0].scrollHeight - $('#scrollMeToo').innerHeight();
    if(delta < 0) {
        //scroll down
        if (curScroll < height2) {
            curScroll += 10;
        }
    }
    else {
        //scroll up
        if (curScroll > 0) {
            curScroll -= 10;
        }
    }
    if (loc >= height && !$('#scrollMeToo').hasClass('appended')) {
        var moreContent ='<a href="google.">a link</a>';
        $('#scrollMeToo').append(moreContent);
        $('#scrollMeToo').addClass('appended');
        console.log('appended');
    }
    $('#scrollMeToo').scrollTop(curScroll);
    return true;
}); 

This modification should suit your needs, according to what you've described. I've also altered the function slightly for some general fixes.

The content will appear just before the bottom of the div is reached, and will only appear once.

you can set overflow:hidden for div .and set css to deselection div content.

 var clicking = false;
 var position;
 var scrollpos;
$(window).mousedown(function(e){
    clicking=true;
    position = e.pageY;
});
$(window).mouseup(function(){
      clicking = false;
})
$(window).mousemove(function(e){
      if(clicking == false) 
            return;
      scrollpos=$('#scrollMeToo').scrollTop();
      $('#scrollMeToo').scrollTop(scrollpos + (e.pageY-position)) ;
})
