Example 1: Return all sibling elements of each
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script src="js/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function() {
$("li.start").siblings().css({
"color": "red",
"border": "2px solid red"
});
});
</script>
<style>
.siblings * {
display: block;
border: 2px solid lightgrey;
color: lightgrey;
padding: 5px;
margin: 15px;
}
</style>
</head>
<body>
<div style="width:500px;" class="siblings">
<ul>ul (父节点)
<li>li (类名为"star"的上一个兄弟节点)</li>
<li>li (类名为"star"的上一个兄弟节点)</li>
<li class="start">li (兄弟节点)</li>
<li>li (类名为"star"的下一个兄弟节点)</li>
<li>li (类名为"star"的下一个兄弟节点)</li>
</ul>
</div>
<p>在这个例子中,我们选择类名称为“star”的li元素的所有兄弟元素。</p>
</body>
</html>
Example 2: Narrow the search (use two parameters to filter the search for sibling elements)
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<script src="js/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function() {
$("li.start").siblings(".1").css({
"color": "red",
"border": "2px solid red"
});
});
</script>
<style>
.siblings * {
display: block;
border: 2px solid lightgrey;
color: lightgrey;
padding: 5px;
margin: 15px;
}
</style>
</head>
<body>
<div style="width:500px;" class="siblings">
<ul>ul(父节点)
<li>li (类名为"star"的上一个兄弟节点)</li>
<li class="1">li(类名为"star"的上一个兄弟节点)</li>
<li class="start">li (兄弟节点)</li>
<li>li(类名为"star"的下一个兄弟节点)</li>
<li class="1">li (类名为"star"的下一个兄弟节点)</li>
</ul>
</div>
<p>在这个例子中,我们缩小搜索结果只返回在类名为“star”和“stop”的li元素之间类名为“1”的兄弟元素。</p>
