jQueryでnoscriptを実装するためのお作法

More than 5 years have passed since last update.

自分のブログの過去記事からの転載ですが。

example.html
<html>
<head>
<style type="text/css">
.jsenabled {
    font-weight:bold;
    border: 2px solid #0000ff;
    padding: 5px;
    width: 400px;
    display: none;
}
.jsdisabled {
    font-weight:bold;
    border: 2px solid #ff0000;
    padding: 5px;
    width: 400px;
}
</style>
<script type="text/javascript" src="js/jquery.js"></script>
<script>
    $(document).ready(function() {
    $(".jsenabled").show();
    $(".jsdisabled").hide();
})
</script>
</head>
<body>
    <div class="jsenabled">JavaScript is enabled</div>
    <div class="jsdisabled">JavaScript is disabled</div>
</body>
</html>

CSSでJavaScriptが有効なときに見せたい領域を非表示(display: none)にしておき、JavaScriptが有効な場合のみjQueryで表示に切り替えるというやり方です。
