Question

目标是在鼠标悬停/悬停时，通过向上滑动显示标题（透明度为文本）（在图像上方），并在鼠标不再悬停时通过向下滑动消失。我是javascript的新手，只有中级HTML和CSS技能。我尝试了大量不同的脚本，但这是我最接近它的工作方式。请帮忙，我不明白我做错了什么！谢谢:)）

这段代码有一些错误，您可以使用slideToggle()：

$(this).find('overlay').animate({
    bottom: '0%'}, 'slow' );
    },
    function() {
    $(this).find('overlay').animate({
    bottom: '-100%'
    },'slow');}
);} // Unexpected `;`

// Better
$('.box').hover(function(){ $(this).find('overlay').slideToggle('slow'); });

如何让我的悬停标题仅在鼠标上方显示并向上/向下滑动？
