本文实例为大家分享了vue实现图书管理系统的具体代码，供大家参考，具体内容如下

组件代码

<template> <div id="app"> <div class="grid"> <div> <h1>图书管理</h1> <div class="book"> <div> <label for="id" v-focus> 编号： </label> <input type="text" id="id" v-model="id" :disabled="flag"> <label for="name"> 名称： </label> <input type="text" id="name" v-model="name"> <button @click="add(addOrUpdate)" :disabled="subFlag">提交</button> </div> </div> </div> <div class="total"> <span>图书总数：</span> <span>{{ totalNum }}</span> </div> <table> <thead> <tr> <th>编号</th> <th>名称</th> <th>时间</th> <th>操作</th> </tr> </thead> <tbody> <tr v-for="book in books"> <td> {{ book.id }} </td> <td> {{ book.name }} </td> <td> {{ book.date | date-format }} </td> <td> <a href="" @click.prevent=" rel="external nofollow" updateBook(book.id)">修改</a> <span>|</span> <a href="" @click.prevent = 'deleteBook(book.id)'>删除</a> </td> </tr> </tbody> </table> </div> </div></template><script> export default { data(){ return{ books:[ { id: 1, name: '三国演义', date: 2525609975000 }, { id: 2, name: '水浒传', date: 2525609975000 }, { id: 3, name: '红楼梦', date: 2525609975000 }, { id: 4, name: '西游记', date: 2525609975000 } ], id:'', name:'', flag:false, // id输入框是否可修改标识 addOrUpdate: 0, // 0代表添加 1代表修改 subFlag:false, // 提交按钮是否禁用（图书存在时禁用） } }, methods:{ // 添加图书的方法 add() { if(this.addOrUpdate===0){ // 添加图书 this.books.push({ id: this.id, name: this.name, date: new Date() }); }else{ const book = this.books.filter((book)=>{ return book.id === this.id; }); book[0].name = this.name } // 添加之后清空input框 this.id = ''; this.name = ''; this.flag = false }, // 更新图书的方法 updateBook(id){ this.addOrUpdate = 1; // 需要修改的当前图书信息 const book = this.books.filter((book)=>{ return book.id === id; }); // 让input框显示相应内容 this.id = book[0].id; this.name = book[0].name; this.flag = true; }, deleteBook(id){ // 获取当前图书的索引 const index = this.books.findIndex((book)=>{ return book.id === id }); this.books.splice(index, 1) } }, computed:{ totalNum(){ return this.books.length } }, // 自定义局部指令 directives:{ focus:{ inserted(el){ // 自动聚焦 el.focus() } } }, // 监视图书是否存在 watch:{ name:{ deep:true, handler(val){ const book = this.books.find((book)=>{ return book.name === val }); if(book){ this.subFlag = true }else{ this.subFlag = false } } } } }</script><style type="text/css"> .grid { margin: auto; width: 530px; text-align: center; } .grid table { border-top: 1px solid #C2D89A; width: 100%; border-collapse: collapse; } .grid th,td { padding: 10px; border: 1px dashed #F3DCAB; height: 35px; line-height: 35px; } .grid th { background-color: #F3DCAB; } .grid .book { padding-bottom: 10px; padding-top: 5px; background-color: #F3DCAB; } .grid .total { height: 30px; line-height: 30px; background-color: #F3DCAB; border-top: 1px solid #C2D89A; }</style>

过滤器文件index.js

import Vue from 'vue'import format from 'date-fns/format'// 自定义过滤器Vue.filter('date-format', function (value, formatStr='yyyy-MM-dd HH:mm:ss') { return format(value, formatStr)});

main.js引入

import './filters'
