ACF 背景图片

Question

我有一个从 ACF 获取数据的 wordpress 网站。该网站的主页有 6 个帖子，其背景图片可以延伸到屏幕的高度。 我想在网站主页中添加另一个帖子/部分。但是当我这样做时，所有图像都会从背景中消失。 谁能帮我这个？ 这些是我的代码；

function bannerLoad(){
     var getHeight = $(window).height();
    $(".home-banner").css('height', getHeight);

    $('.home-banner').each(function(){
        var homebannerid = $(this).attr('id');
        var imgsrc = $(this).find('img.slide-img').attr('src');
        $("#"+homebannerid).backstretch(imgsrc, {speed: 300});
    });
