本文實例為大家分享了vue實現搜索功能的具體代碼，供大家參考，具體內容如下
methods (要有一定的觸發條件才能執行，如點擊事件)
<template> <div class="safetyInfo"> <input type="text" name="" id="" placeholder="搜索" v-model="search"/> <button @click="btn">搜索</button> <ul v-for="list in searchData"> <li> <span>{{list.name}}</span> <span>{{list.date}}</span> <span>{{list.depart}}</span> </li> </ul> </div></template> <script>export default { name: 'HelloWorld', data () { return { search:'', searchData: '', products:[ //假數據 {name:"數據1",date:'2018-01-04',depart:'瀘化工1'}, {name:"數據2",date:'2018-01-25',depart:'瀘化工2'}, {name:"數據3",date:'2018-02-10',depart:'瀘化工3'}, {name:"數據4",date:'2018-03-04',depart:'瀘化工4'}, {name:"數據5",date:'2018-05-24',depart:'瀘化工5'}, {name:"數據6",date:'2018-10-29',depart:'瀘化工6'} ] } }, methods:{ btn:function(){ var search = this.search; if (search) { this.searchData = this.products.filter(function(product) { console.log(product) return Object.keys(product).some(function(key) { console.log(key) return String(product[key]).toLowerCase().indexOf(search) > -1 }) }) } } }}</script>computed (在HTML DOM加載后馬上執行的，如賦值):
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"> <title>Document</title><script src="https://unpkg.com/vue/dist/vue.js"></script></head><body> <div id="app"><input v-model='search' /><ul v-for="item in searchData "><li>{{item.name}},價格:￥{{item.price}}</li></ul></div> <script>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;}}})</script> </body></html>注：some()為數組中的每個元素執行一次callback函數，直到它找到一個返回值為可以轉化為布爾值true的值,此時some()方法將立刻返回true，否則立刻返回false
by the way:
watch 它用于觀察Vue實例上的數據變動。對應一個對象，鍵是觀察表達式，值是對應回調。值也可以是方法名，或者是對象，包含選項。
所以他們的執行順序為：默認加載的時候先computed再watch，不執行methods；等觸發某一事件后，則是：先methods再watch。
