之前工作中有一个需求，就是在一堆图片列表中，点击具体的图片，并从界面移除；点击具体的图片，下载；这是一个思路
<style type="text/css" media="screen">
.box {
50px;
height: 60px;
margin: 5px 0;
}
.box:nth-child(1) {
background: red;
}
.box:nth-child(2) {
background: blue;
}
.box:nth-child(3) {
background: red;
}
.box:nth-child(4) {
background: pink;
}
</style>
<body>
<div class="father">
<div class="box">1</div>
<div class="box">2</div>
<div class="box">3</div>
<div class="box">4</div>
</div>
<button type="button" class="btn">删除</button>
<script src="https://cdn.bootcss.com/jquery/3.3.1/jquery.js"></script>
<script>
$(function() {
var deleteIndex=0;
$(".box").click(function() {
console.log($(this).index());
deleteIndex = $(this).index();
$(this).siblings().css({"border":"none"});
// $(this).css({"border-width":"1px","border-style":"solid","border-color":"yellow"});
$(this).css({"border":"10px solid yellow"});
});
$(".btn").click(function() {
// $("father").find[]
$(".father").find(".box")[deleteIndex].remove();
});
});
</script>
</body>
