How do I detect horizontal scrolling with jQuery?

如何使用 jQuery 检测水平滚动？

This will get all scrolls:

这将获得所有卷轴：

$(window).scroll(function () {
    alert('in');
});

I want just the horizontal one.

我只想要水平的。

This seems to work.

这似乎有效。

var lastScrollLeft = 0;
$(window).scroll(function() {
    var documentScrollLeft = $(document).scrollLeft();
    if (lastScrollLeft != documentScrollLeft) {
        console.log('scroll x');
        lastScrollLeft = documentScrollLeft;
    }
});

An update that shows direction left or right in a horizontal scroll based on code above:

根据上面的代码在水平滚动中显示向左或向右方向的更新：

var lastPos = 0;
$(window).scroll(function() {
    var currPos = $(document).scrollLeft();

    if (lastPos < currPos) {
        console.log('scroll right');
    } 
    if (lastPos > currPos) 
    {
        console.log('scroll left');
    }

    lastPos = currPos;
});

dunderwood's jsFiddle link didn't actually contain his code. I've forked his jsFiddle with what a mixture of what he posted here and what's on the jsFiddle:

dunderwood 的 jsFiddle 链接实际上并不包含他的代码。我已经将他的 jsFiddle 与他在这里发布的内容和 jsFiddle 上的内容混合在一起：

var lastPos = 0;
$(window).scroll(function() {
    var currPos = $(document).scrollLeft();

    if (lastPos < currPos) {
        $('#current').html('Right');
    }
    if (lastPos > currPos) {
        $('#current').html('Left');
    }

    lastPos = currPos;
});

window.onresize = function() { 
    if ( $("div").outerWidth() < $("div").get(0).scrollWidth ) {
        console.log("foo bar scrollbar");
    } else {
        console.log(" no scrolling ");
    }
};
