Fullpage.js。添加滚动延迟 [英] Fullpage.js. Adding a scroll delay

问题描述

我有一个divbox，当用户滚动到下一页时，使用.fp-viewing作为锚点逐渐淡出，以启动过渡效果。当触发.fp-viewing时，页面开始滚动，并在动画结束前将框滚动到视图之外。

I have a div "box" which fades gradually using ".fp-viewing" as an anchor to start the transition effect when a user scrolls to the next page. The thing is the page starts scrolling when .fp-viewing is triggered and scrolls box out of view before the finish of the animation.

当触发.fp-viewing直到box在4s内完成动画时，如何延迟滚动的开始？

How can I delay the start of the scrolling when .fp-viewing is triggered till box has done its animation in 4s?

.box{
  transition: all 4s ease-out;
  -webkit-transition: all 4s ease-out;
}

.fp-viewing-2 .box{
  opacity: 0;
}

var delay = 2000; //milliseconds
var timeoutId;
var animationIsFinished = false;

new fullpage('#fullpage', {
      sectionsColor: ['yellow', 'orange', '#C0C0C0', '#ADD8E6'],
    onLeave: function(origin, destination, direction){
        var curTime = new Date().getTime();

        //animating my element
        $('#element').addClass('animate');

        clearTimeout(timeoutId);

        timeoutId = setTimeout(function(){
            animationIsFinished = true;

            fullpage_api.moveTo(destination.index + 1);
        }, delay);

        return animationIsFinished;
    },
});
