我想通过滚动页面上的任何位置来触发具有溢出内容的 div 滚动,而不仅仅是通过移动鼠标并在 div 内单击。另外,我想隐藏 div 的滚动条,以便只有页面的滚动条可见。

该解决方案最好是基于 CSS 的,但也可以使用 JS 解决方案。

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

我会在这里复制代码,但在那里我放了一堆填充文本来触发滚动条。

不过,供您参考,我想在滚动页面时滚动的内部 div 的名称有一个id="scrollMeToo".

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 {

这应该可以满足您的需要,如果您不希望文档滚动,只需return true;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;
}

为了改变滚动速度,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值更改为您需要的任何值。

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;
}); 

根据您的描述,此修改应该适合您的需要。我还稍微更改了一些常规修复的功能。

内容将在到达 div 底部之前出现,并且只会出现一次

您可以为 div 设置溢出:隐藏,并将 css 设置为取消选择 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)) ;
})
