我正在处理杂货清单，您可以在其中搜索杂货并将其添加到清单中。我的杂货项目是从MySQL表填充的，文本已添加到称为“ foodcard”的div中。我的Jquery脚本almost完全按照我的要求工作，除了可以看到所有150多个卡片，并且只有当您开始在输入框中键入内容时，卡片才会在相关搜索词中隐藏并消失。我在弄清楚如何隐藏页面加载时仅显示搜索字词时遇到麻烦。请给我我的所有代码，但请告诉我是否需要添加]
$(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;
