jQuery Waypoints触发一次

问题描述

我正在使用 http://imakewebthings.com/jquery-waypoints 和当用户向下滚动到类为div1的区域时，我需要执行一些操作.但是，我只需要触发一次，而不是每次用户滚动到该位置时都触发​​它. — 仅一次

I am using http://imakewebthings.com/jquery-waypoints andI need to do some action when the user scrolls down to the area with the class div1. However, I need it only fire once and not every time the user scrolls to that location. — only once

$('.div1').waypoint(function(direction) 
{
    alert(CARRY OUT MY ACTION);
});

这仅需要在该部分的第一个滚动中(向上或向下)进行.

This needs to only happen on the first scroll to that section — up or down.

推荐答案

triggerOnce()被替换为destroy().只需添加this.destroy().

triggerOnce() is replaced with destroy().Just add this.destroy().

$('.div1').waypoint(function(direction){
    alert('CARRY OUT MY ACTION')
    this.destroy()
});
