如何在点击时过滤项目？

772

我有一个包含一组不同元素的容器。所有物品均采用颜色编码。只有三种颜色。每个元素都有一个样式类名称 ( class)，它允许您将每个元素与其所需的样式相关联。一般容器中的元素是不按颜色分组的，实际上是分散在里面的。在视觉上它看起来像这样：

这html是css代码：

body {overflow: hidden; width: 100%; margin: 0; text-align: center;}

.container {width: 100%; margin: 0 auto;}

.filter {
  float: left; cursor: pointer; width: 23%;
  margin: 0.5%; margin-bottom: 10px; padding: 0.5%;
  background: white; text-align: center; color: black;
  box-shadow: 0 1px 3px rgba(0, 0, 0, 0.1), 0 1px 2px rgba(0, 0, 0, 0.2);
}

.item {
  float: left; width: 23%; height: 20px; line-height: 20px;
  margin: 0.5%; padding: 0.5%;
  box-shadow: 0 1px 3px rgba(0, 0, 0, 0.1), 0 1px 2px rgba(0, 0, 0, 0.2);
  transition: all 1s;
}

.blue {background: deepskyblue;}
.red {background: orangered;}
.green {background: limegreen;}

<div class="container">
  <div class="filter">Синий</div>
  <div class="filter">Красный</div>
  <div class="filter">Зеленый</div>
  <div class="filter">Показать все</div>

  <div class="item blue">1</div>
  <div class="item red">2</div>
  <div class="item blue">3</div>
  <div class="item green">4</div>
  <div class="item blue">5</div>
  <div class="item red">6</div>
  <div class="item red">7</div>
  <div class="item green">8</div>
  <div class="item blue">9</div>
  <div class="item green">10</div>
  <div class="item red">11</div>
  <div class="item green">12</div>
  <div class="item blue">13</div>
  <div class="item blue">14</div>
  <div class="item green">15</div>
  <div class="item red">16</div>
</div>

问题：点击颜色名称时，如何过滤所有元素，只显示所选颜色的元素，隐藏所有其他元素？例如，当您单击“红色”时，它应如下所示：

对问题标签中指示的任何方式和技术的实施感兴趣。它可以是：CSS、jQuery、Native Script。

带有 JS 的选项，最好使它们更通用 - 与颜色数量无关。

const btsFilter = Array.from(document.querySelectorAll('[data-filter]'))

const colors = ['blue', 'green', 'red' /*, .... */]
const map = colors.reduce((a, e) => {
  const bt = btsFilter.find((btel) => btel.dataset.filter === e)
  const els = Array.from(document.querySelectorAll(`.item.${e}`))
  let hide = false
  a.set(e, (fl, reset) => {
    if (fl) {
      reset || bt.classList.add('selected')
      if (!hide) return
      hide = false
      els.forEach((e) => e.classList.remove('hide'))
    } else {
      bt.classList.remove('selected')
      if (hide) return
      hide = true
      els.forEach((e) => e.classList.add('hide'))
    }
  })
  return a
}, new Map())
map.set('reset', (fl) => fl && colors.forEach((e) => map.get(e)(fl, true)))

btsFilter.forEach((i) => i.addEventListener('click', ({ target: { dataset: { filter } } }) => {
  for (let [key, show] of map.entries()) {
    show(filter === key)
  }
}))
