我有一个引导按钮列表,还有一个搜索框,我想实现一个过滤功能(最好用javascript)来过滤按钮数量:
引导代码在这里:

<div class="row">
<div class="col-lg-2">
<div class="panel">
<input type="text" id="search" placeholder="Type to search">
<br>
<button type="button" class="btn btn-secondary">AA1009</button>
<button type="button" class="btn btn-secondary">AA1010</button>
<button type="button" class="btn btn-secondary">BA1098</button>
<button type="button" class="btn btn-secondary">BB1890</button>
<button type="button" class="btn btn-secondary">C89761</button>
<button type="button" class="btn btn-secondary">CD1667</button>
<button type="button" class="btn btn-secondary">GG7830</button>
<button type="button" class="btn btn-secondary">GF65372</button>
<button type="button" class="btn btn-secondary">BH6537</button>
<button type="button" class="btn btn-secondary">HGB562</button>
<button type="button" class="btn btn-secondary">LK9063</button>
<button type="button" class="btn btn-secondary">CP9871</button>
<button type="button" class="btn btn-secondary">IRON87</button>
<button type="button" class="btn btn-secondary">ACT567</button>
<button type="button" class="btn btn-secondary">MPO760</button>
<button type="button" class="btn btn-secondary">GH5436</button>
<button type="button" class="btn btn-secondary">NBH894</button>
<button type="button" class="btn btn-secondary">GHFDF6</button>
<button type="button" class="btn btn-secondary">US4536</button>
<button type="button" class="btn btn-secondary">MO9854</button>
</div>
</div>
</div>
过滤器应该像这样工作: 如果键入AA,则只显示带有文本&#34; aa&#34;的按钮。应该是可见的。
我在网上搜索时得到的唯一建议是使用list.js,但我想知道是否可以有一个更简单的javascript搜索实现。
答案 0 :(得分:3)

jquery:
var $button = $('.btn');
$('#search').keyup(function() {
var re = new RegExp($(this).val(), "i"); // case-insensitive
$button.show().filter(function() {
return !re.test($(this).text());
}).hide();
});
基本上,每次用户键入输入以过滤元素时,您都希望运行该函数。您隐藏了与用户输入不匹配的所有按钮。
