我正在尝试在延迟后向一个范围添加一个类但没有任何反应。 Jquery的:
$(".arrow-left").delay(1000).queue(function() {
$(this).addClass("active")
});
$(".arrow-right").delay(1000).queue(function() {
$(this).addClass("active")
});
HTML:
<nav>
<span class="arrow-left">
<div class="arrow-l">
<img alt="" src="images/prev-arrow.svg">
</div>
</span>
<span class="arrow-right">
<div class="arrow-r">
<img alt="" src="images/next-arrow.svg">
</div>
</span>
</nav>

你的jQuery是正确的。问题可能是div
不是span
的有效子项,因此可能不会继承active
类的属性(取决于浏览器实现)。
更改为:
<nav>
<div class="arrow-left">
<div class="arrow-l">
<img alt="" src="images/prev-arrow.svg">
</div>
</div>
<div class="arrow-right">
<div class="arrow-r">
<img alt="" src="images/next-arrow.svg">
</div>
</div>
</nav>
$(".arrow-left").delay(1000).queue(function() {
$(this).addClass("active")
});
$(".arrow-right").delay(1000).queue(function() {
$(this).addClass("active")
});

.arrow-left, .arrow-right {
display: inline-block;
}
.active {
zoom: 1.2;
border: 5px solid red;
}
