Question

当我尝试动态选择的样式不加载时，我试图想出一种默认为标准样式的方法。例如，如果ORG_ID与有效文件无关，我会尝试404访问它。

<head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=0" />
    <title>WhiteLabel</title>
    <link rel="shortcut icon" href="images/favicon.png" />
    <link rel="apple-touch-icon" href="images/apple-touch-icon.png" />
    <script>
        try {
            var ORG_ID = window.location.search.match(/org_id=([0-9]+)/)[1];
        } catch (e) {
            console.log("Error encounterd: " + e);
            document.write("<link rel='stylesheet' href='js/jquery.mobile-1.2.0/jquery.mobile-1.2.0.min.css'>");
        }
        if (ORG_ID[1]) {
            document.write("<link rel='stylesheet' href='themes/" + ORG_ID + ".min.css'>");
            document.write("<link rel='stylesheet' href='js/jquery.mobile-1.2.0/jquery.mobile.structure-1.2.0.min.css'>");
        } else {
            document.write("<link rel='stylesheet' href='js/jquery.mobile-1.2.0/jquery.mobile-1.2.0.min.css'>");
        } 
    </script>

</head>

如何在未加载动态样式表时选择默认样式表
