【问题描述】：
我正在制作一份杂货清单，您可以在其中搜索杂货并将其添加到您的清单中。我的杂货商品是从 MySQL 表中填充的，文本被添加到名为“foodcard”的 div 中。我的 Jquery 脚本几乎完全按照我的意愿工作，除了所有 150 多张卡片都是可见的，并且只有当您开始在输入框中输入时，卡片才会隐藏并在相关搜索词中淡出。我无法弄清楚如何在页面加载时隐藏卡片并仅显示搜索词。生病给你我所有的代码，但请告诉我是否需要包含更多
$(document).ready(function(){
$('#grcsearch').on('keyup', function () {
var grcsearch = $('#grcsearch').val().toLowerCase();
$('.foodcard').each(function(){
var $this = $(this);
if($this.text().toLowerCase().indexOf(grcsearch) === -1)
$this.closest('.foodcard').fadeOut();
else $this.closest('.foodcard').fadeIn();
})
});
});.wrapper {
text-align: center;
}
.grocerylistcard {
width: 85%;
height: 90%;
border-radius:15px;
padding-bottom: 20px;
padding-top: 20px;
