我的網站有這個問題：80% 的時間網站加載完美，沒有任何問題。有時它會在下圖中出現問題：這是我在索引中調用的 javascript 文件：    <script type='text/javascript' src="js/jquery3.1.1.js"></script>    <script type='text/javascript' src="js/lightgallery.min.js"></script>    <script type='text/javascript' src='js/slick.min.js'></script>    <script type='text/javascript' src='js/lazy.min.js'></script>    <script type='text/javascript' src='js/main.min.js'></script>    <script type='text/javascript' src="js/picker.min.js"></script>    <script type="text/javascript" src="https://nibirumail.com/docs/scripts/nibirumail.cookie.min.js"></script>    <script type="text/javascript" src="https://web4.deskline.net/accommodationtrentino/it/qfind/script/TRN/a2befeb0-66ed-4f20-bf1a-520a5959f8cd/x?pageType=4&containerId=QF1&selAdultsSearchLine1=2&showText=true&showLink=true&lkCS=DEFAULT&width=300"></script>    <script type="text/javascript" src="https://web4.deskline.net/accommodationtrentino/it/qfind/script/TRN/a2befeb0-66ed-4f20-bf1a-520a5959f8cd/x?pageType=4&containerId=QF2&selAdultsSearchLine1=2&showText=true&showLink=true&lkCS=DEFAULT&width=300"></script>    <script type='text/javascript' src="https://cdnmks.suggesto.eu/vtn-hook/lib/sweWidget2.js?t=201704141221" ></script>    在 main.min.js 中調用了 lazy 和 slick 對象：$(function() {        $('.lazy').lazy();    });$(document).ready(function(){        $('.slider-nav').slick({            lazyLoad: 'ondemand',            autoplay: true,  autoplaySpeed: 5000,        dots: true,  infinite: false,  speed: 300,  slidesToShow: 4,  slidesToScroll: 1,  responsive: [    {      breakpoint: 1200,      settings: {          lazyLoad: 'ondemand',        slidesToShow: 3,        slidesToScroll: 1,              }    },    {      breakpoint: 900,      settings: {        slidesToShow: 2,        slidesToScroll: 1      }    }    // You can unslick at a given breakpoint now by adding:    // settings: "unslick"    // instead of a settings object  ]});     });在調用其他腳本之前，似乎沒有正確加載 JQuery。有人能幫忙嗎？
