【问题标题】：How to filter/search through materialize css/bootstrap when cards are used?使用卡片时如何通过物化 css/bootstrap 过滤/搜索？

【问题描述】：

我正在尝试使用物化 css 和引导程序制作一个 html 页面。所以我想放置表示 youtube 视频的卡片，并且我想要一个搜索栏，可以浏览卡片并显示正在搜索的卡片...... 所以我找到了一个解决方案，它对我的预期有一半是正确的。

.searchBox{
    margin: 4em;
}

.grid-container{
    display: grid;
    border: 1px solid black;
    grid-template-columns: 70% 10% 20%;
    margin: 4em;
}

.grid-item1{
    display: grid;
    grid-template-columns: repeat(auto-fit, minmax(100px, 1fr));
    grid-gap: 20px;
    border: 1px solid black;
}


.grid-item2{
    border: 1px solid black;
}
.grid-item3{
    border: 1px solid black;
}

如果你运行代码 sn-p 你会知道当你搜索“aaa/bbb/ccc”时，卡片图像和“gsp430/.../...”部分完全消失了。当您搜索“gsp430”之类的内容时，卡片标题和卡片图像也会消失......我想实现一些可以显示整张卡片的东西...... 有什么解决办法吗？

【问题讨论】：

标签： javascript html css bootstrap-4 materialize

【解决方案1】：

您正在运行 Bootstrap 3 .JS (bootstrapcdn) 和 Bootstrap 5 .CSS (jsdelivr)。

这肯定会导致布局问题，但对于卡片，一切都很好……不要调用 2 个不同的版本。你不需要他们两个。

【讨论】：

好的，我改一下再试一次

【解决方案2】：

我在两点更改了您的脚本：

过滤器将仅应用于.card-content 元素：$("#myDIV .card-content").filter(...)
然后将实际的toggle() 应用于过滤元素的closest() 父级：$(this).closest(".card").toggle(vis);

变量vis之前计算为let vis=$(this).text().toLowerCase().indexOf(value) > -1;。

$(document).ready(function() {
  $("#myInput").on("keyup", function() {
    var value = $(this).val().toLowerCase();
    $("#myDIV .card-content").filter(function() {
      let vis = $(this).text().toLowerCase().indexOf(value) > -1;
      $(this).closest(".card").toggle(vis)
    });
  });
});

document.addEventListener('DOMContentLoaded', function() {
      var elems = document.querySelectorAll('.sidenav');
      M.Sidenav.init(elems);
});

.searchBox {
  margin: 4em;
}

.grid-container {
  display: grid;
  border: 1px solid black;
  grid-template-columns: 70% 10% 20%;
  margin: 4em;
}

.grid-item1 {
  display: grid;
  grid-template-columns: repeat(auto-fit, minmax(100px, 1fr));
  grid-gap: 20px;
  border: 1px solid black;
}

.grid-item2 {
  border: 1px solid black;
}

.grid-item3 {
  border: 1px solid black;
