マウスを動かしてdiv内をクリックするだけでなく、ページ上の任意の場所をスクロールして、コンテンツがオーバーフローしたdivのスクロールをトリガーしたいと思います。また、ページのスクロールバーのみが表示されるように、divのスクロールバーを非表示にします。

できれば、ソリューションはCSSベースですが、JSソリューションも機能します。

これが問題を示す私のjsfiddleです:http://jsfiddle.net/trpeters1/RMZsX/8/

ここにコードをコピーしますが、スクロールバーをトリガーするために大量のフィラーテキストを配置します。

参考までに、ページをスクロールしてスクロールしたい内部divの名前には。が付いていid="scrollMeToo"ます。

これで必要な処理が実行されます。ドキュメントをスクロールしたくない場合は、をに変更しreturn true;return false;ください。

非jQueryメソッド:

        curScroll -= 10;
    }
    document.getElementById('scrollMeToo').scrollTop = curScroll;

スクロール速度を変更するには、ニーズに合わせてこのブロックを変更するだけです。

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

10値を必要なものに変更するだけです。

アップデート:

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.com">a link</a>';
        $('#scrollMeToo').append(moreContent);
        $('#scrollMeToo').addClass('appended');
        console.log('appended');
    }
    $('#scrollMeToo').scrollTop(curScroll);
    return true;
}); 

あなたが説明したことによれば、この変更はあなたのニーズに合うはずです。また、いくつかの一般的な修正のために関数を少し変更しました。

コンテンツは、divの下部に到達する直前に表示され、1回だけ表示されます。

divのoverflow:hiddenを設定し、cssをdivコンテンツの選択解除に設定できます。

 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)) ;
})
