我目前正在尝试摆脱一堆CSS动画并替换为Velocity.js(沿着新动画构建的方式)。
目前我有一个网格项目:
<div class="video-thumbnail">
<img src="http://placehold.it/1280x720" class="imgspacer" alt="{$info['title']}" />
<div class="overlay">
<a href="http://bbc.co.uk" class="thumbnail-link">
<div class="title">
<div class="title-display">
<h5 class="SlideIn">Title One</h5>
<h6 class="SlideIn">Title Two</h6>
</div>
</div>
</a>
</div>
</div>
这是通过CSS来控制淡入.overlay
元素。我当时想做的是h5
&amp; h6
课程可以向上滑动。
我写了以下代码:
$('.overlay').hover(function(){
$(this).find('.SlideIn').velocity("transition.slideUpIn", {stagger: 100, duration: 500});
});
但似乎没有发生任何事情。我对Javascript很陌生,所以我假设我在某个地方犯了一个愚蠢的错误,但是无法弄清楚它是什么。
我在下方添加了一个完整的代码段,也可以找到here
$('.overlay').hover(function(){
$(this).find('.SlideIn').velocity("transition.slideUpIn", {stagger: 100, duration: 500});
});

答案 0 :(得分:0)
正如@ AldoRomo88和@jmcgriz所提到的,页面上脚本的加载顺序存在问题。
我通过简单地首先加载查询(并在我自己的服务器上托管脚本来修复问题!)
