jQuery中是否有垂直滚动事件 [英] Is there a vertical scroll event in jQuery

问题描述

我有一个与scroll()事件绑定的函数，但事实是我希望仅在垂直滚动(我也有一些水平滚动)的情况下才触发该函数.

I have a function that I bound with scroll() event, but the fact is I want the function to be triggered only in case of vertical scroll ( I have some horizontal scroll too).

我在jQuery文档中没有看到这种可能性，这样做有技巧吗?

I didn't see such possibility in the documentation of jQuery, might there be a trick to do so?

推荐答案

没有特定事件，但是您可以测试.scrollLeft()位置以查看它是否已从先前存储的位置移出.

There isn't a specific event, but you could test the .scrollLeft() position to see if it has moved from a previously stored position.

类似这样的东西:

var prevLeft = 0;
$(document).scroll( function(evt) {
    var currentLeft = $(this).scrollLeft();
    if(prevLeft != currentLeft) {
        prevLeft = currentLeft;
        console.log("I scrolled horizontally.");
    }
});
