使用jQuery在Bootstrap 4中过滤卡片

Question

我正在尝试使用bootstrap 4的新卡组件创建一个由许多卡填充的页面.

我想创建一个搜索栏,搜索时会筛选出标题与搜索查询不匹配的卡片.

这是我想到的东西.Plunker

我希望卡片能够得到类似的东西display: none,或者opacity:0它们是否匹配.

我目前正在尝试编写onChange搜索栏的功能.我会发布,如果我能弄明白的话.

我也试过使用内置代码段功能.

Answer 1

这是一个快速示例,说明如何使用jQuery的contains选择器来完成它:

$('.searchbox-input').change( function () {
    $('.card').show();
    var filter = $(this).val(); // get the value of the input, which we filter on
    $('.container').find(".card-title:not(:contains(" + filter + "))").parent().css('display','none');
});

目前这是设置为在更改搜索输入时发生,您可能需要设置一个提交按钮并将其激活提交.
