首先引入Vue这个就不解释了
HTML部分
<div id="app"> <input v-model=‘search‘ /> <ul v-if="searchData.length > 0"> <li v-for="item in searchData">{{item.name}},价格:￥{{item.price}}</li> </ul> <div v-else>暂无数据</div> </div>
JS部分
var vm = new Vue({ el: ‘#app‘, data: { search: ‘‘, products: [{ name: ‘苹果‘, price: 25, category: "水果" }, { name: ‘香蕉‘, price: 15, category: "水果" }, { name: ‘雪梨‘, price: 65, category: "水果" }, { name: ‘宝马‘, price: 2500, category: "汽车" }, { name: ‘奔驰‘, price: 10025, category: "汽车" }, { name: ‘柑橘‘, price: 15, category: "水果" }, { name: ‘奥迪‘, price: 25, category: "汽车" }] }, 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; } } })
非常实用把，试一下哦
