求助，用jq 删除过多的img标签
<div class"detail"> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> <img alt="" src="/img/img.jpg"/> </div>
如以上html 代码 只保留前三个img标签，剩下全部删掉？ 请高手帮帮忙。使用jq

代码第一行少个等于号，你试试：获取大于2的img元素，remove（）$("img:gt(2)").remove() -
