Question

我想通过在页面上的任何位置滚动来触发带有溢出内容的div的滚动，而不仅仅是移动鼠标并在div中单击。此外，我想隐藏div的滚动条，只有页面的滚动条可见。

最好是解决方案是基于CSS的，但JS解决方案也可以。

这是我的jsfiddle，它演示了这个问题：http://jsfiddle.net/trpeters1/RMZsX/8/

我在这里复制代码，但是我在那里放了一堆填充文本来触发滚动条。

但是，对于您的参考，我想滚动页面时滚动的内部div的名称为id="scrollMeToo"。

Answer 1

var curScroll = 0;

$(window).bind('mousewheel DOMMouseScroll', function(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;
    }
    $('#scrollMeToo').scrollTop(curScroll);
    return true;
});

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

这应该可以满足您的需求，如果您不想滚动文档，只需将return true;更改为return false;。

非jQuery方法：

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;
}

要更改滚动速度，只需修改此块以满足您的需要：

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

只需将10值更改为您需要的值。

<强>更新

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;
});

根据您所描述的内容，此修改应符合您的需求。我也稍微改变了一些常规修复功能。

内容将在到达底部之前显示为，并且只会出现一次。

Answer 2

你可以设置overflow：hidden for div。并设置css来取消选择div内容。

 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)) ;
})

通过滚动页面上的任何位置滚动溢出的div
