<div class="ceo-container">
    	<!--多图广告位-->
    	<div class="ceo_ads">

        </div>
        <script>
            /* jQuery定时显示广告 */
            var obj = [{
                time: '2024-06-20 12:30:00',
                imgUrl: '/images/1.jpg',

            }];
            var date = new Date(),time = date.getTime();
            for(i = 0; i < obj.length; i++) {
                var o = obj[i],
                    t = (new Date(o.time)).getTime(),
                    boo = t - time > 0 ? true : false;
                if(boo) {
                    var li=$('<li><a href="'+o.href+'" target="_blank"><img src="'+o.imgUrl+'" alt="'+o.desc+'"></a></li>');
                }else{
                    var li=$('<li><a href="/ad" target="_blank"><img src="/images/default.png" alt="广告位招租"></a></li>');
                }
                //追加到广告盒子内部最前面位置
                $('.ceo_ads').prepend(li);
