VUE-搜索過濾器

VUE很是實用的搜索過濾，喜歡點個贊哦

廢話很少說，先來看看效果

1 引入vue

<script src="https://cdn.jsdelivr.net/npm/vue"></script>

2 HTML

<div id="app">
    <input v-model='search' />
    <ul v-if="searchData.length > 0">
      <li v-for="item in searchData">{{item.name}},價格:￥{{item.price}}</li>
    </ul>
    <div v-else>暫無數據</div>
</div>

3 JS

var vm = new Vue({
  el: '#app',
  data: {
    search: '',
    products: [{
      name: '蘋果',
      price: 25,
      category: "水果"
    }, {
      name: '香蕉',
      price: 15,
      category: "水果"
    }, {
      name: '雪梨',
      price: 65,
      category: "水果"
    }, {
      name: '寶馬',
      price: 2500,
      category: "汽車"
    }, {
      name: '奔馳',
      price: 10025,
      category: "汽車"
    }, {
      name: '柑橘',
      price: 15,
      category: "水果"
    }, {
      name: '奧迪',
      price: 25,
      category: "汽車"
    }]
  },
  computed: {
    searchData: function() {
      var search = this.search;

      if (search) {
        return this.products.filter(function(product) {
          return Object.keys(product).some(function(key) {
            return String(product[key]).toLowerCase().indexOf(search) > -1
          })
        })
      }

      return this.products;
    }
  }
})
