将 类 切换为 jQuery 中的事件处理程序
Toggle classes with this as an event handler in jQuery
我想在单击与其关联的可折叠 class 按钮时独立切换内容 class。我简要阅读了有关在事件处理程序中使用它的信息。到目前为止,我使用它的方式是切换可折叠的 class(即按钮)。
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<title></title>
<style>
.collapsible {
background-color: #777;
color: white;
cursor: pointer;
padding: 18px;
width: 100%;
border: none;
text-align: left;
outline: none;
font-size: 15px;
}
.active, .collapsible:hover {
background-color: #555;
}
.content {
padding: 0 18px;
overflow: hidden;
display: none;
background-color: #f1f1f1;
}
</style>
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$(".collapsible").on("click", function(){
$(".content").toggle();
});
});
</script>
</head>
<body>
<button type="button" class="collapsible">Open Section 1</button>
<div class="content contentDisp">
<p>Hello There.</p>
</div>
<button type="button" class="collapsible">Open Section 2</button>
<div class="content contentDisp">
<p>Hello there.</p>
</div>
<button type="button" class="collapsible">Open Section 3</button>
<div class="content contentDisp">
<p>Hello there.</p>
</div>
</body>
这接近我想要的,但我不想切换按钮,而是想在单击按钮时切换 div。
<script type="text/javascript" charset="utf-8">
$(document).ready(function(){
$(".collapsible").on("click", function(){
$("this").toggle();
});
});
</script>
您可以通过指定按钮的 class 名称将 this
与 next()
结合使用。
$(document).ready(function(){
$(".collapsible").on("click", function(){
$(this).next('.content').toggle();
});
});
.collapsible {
background-color: #777;
color: white;
cursor: pointer;
padding: 18px;
width: 100%;
border: none;
text-align: left;
outline: none;
font-size: 15px;
}
.active, .collapsible:hover {
background-color: #555;
}
.content {
padding: 0 18px;
overflow: hidden;
display: none;
background-color: #f1f1f1;
