Like this?
像这样？
$('.m-carousel-inner').find('img:first');
See :first
见：第一
First part $('.m-carousel-inner')is the selector for your container element with class .m-carousel-innerwhich will return the jquery wrapped DOM element, and apply .find('img:first')to find the first instance of img as its child at any level.
第一部分$('.m-carousel-inner')是带有 class 的容器元素的选择器.m-carousel-inner，它将返回 jquery 包装的 DOM 元素，并应用于.find('img:first')在任何级别查找 img 的第一个实例作为其子元素。

in jquery you could
在 jquery 中你可以
<script>$('.m-carousel-inner img:first');</script>
回答by XxANxX
you can also use jQuery first()function with the jQuery selector
您还可以将 jQueryfirst()函数与 jQuery 选择器一起使用
<script> $('.m-carousel-inner img').first(); </script>
