Proper use of focus events can improve the user's experience on the web page. This article will explore how to leverage the potential of jQuery focus events to improve web page user experience through introduction and sample code.

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<style>
input:focus {
background-color: #f0f0f0;
}
</style>
</head>
<body>
<input type="text" placeholder="请输入内容">
</body>
</html>In this example, when the user clicks on the input box, the background color of the input box will turn to light gray. When the input box loses focus, The background color will return to the default value.

<!DOCTYPE html>
<html>
<head>

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<style>
.nav-item {
padding: 10px;
background-color: #f0f0f0;
}
.nav-item:focus {
background-color: #ccc;
}
</style>
</head>
<body>
<ul>
<li class="nav-item" tabindex="1">首页</li>
<li class="nav-item" tabindex="2">关于我们</li>
<li class="nav-item" tabindex="3">产品</li>
<li class="nav-item" tabindex="4">联系我们</li>
</ul>
</body>
</html>In this example, when the user switches focus through the keyboard Tab key, the background color of the navigation bar menu will change, letting the user clearly know the currently selected navigation item.
