jQuery-如何将滚动视为单个事件? [英] jQuery - how to treat scroll as single event?

问题描述

当我将功能绑定到滚动和滚动鼠标滚轮一次时，该功能将运行七或八次.我希望它在滚动鼠标滚轮一次时仅运行一次，这可能吗?我使用以下代码:

When I bind function to scroll and scroll mousewheel once, the function runs seven or eight times. I want it to run only once when I scroll the mousewheel once, is this possible? I use this code:

$(document).ready(function () {
    $(window).bind('scroll', function() {
        alert("Scroll.");          
    }   
    });
});

推荐答案

尝试

$(document).ready(function () {
    var timerId;
    $(window).bind('scroll', function() {
        clearTimeout(timerId)
        timerId = setTimeout(function(){
            alert("Scroll.");          
        }, 200)
    });
});
