vue.js快速搭建图书管理平台

前言

上一期简单讲解了 vue 的基本语法，这一次我们做一个小项目，搭建一个简单的图书管理平台，能够让我们更深刻的理解这门语言的妙用。

1、DEMO 样式

　　首先我们需要搭建一个简单的 demo 样式，推荐大家使用 bootstrap，可以很快的搭建出一个清晰简洁的页面。

　　给大家分享一段我的代码吧。

        <div class="container">
            <div class="col-md-6 col-md-offset-3">

　　运用了 bootstrap 的栅格系统，和一些简单的组件，不光简单快捷，还能自动实现响应式呢。

　　而且做出来的效果也不难看，挺整洁的。

　　给大家看下刚开始的效果图。

　　如果对这个 CSS 框架没有了解的话，自己写一下样式也没关系。

2、创建 vue 实例

　　接下来，我们导入自己的 JS 文件，创建一个 vue 实例。

new Vue({
    el: '#app',
    data: {
        book: {
            id: 0,
            author: '',
            name: '',
            price: ''
        },
        books: [{
            id: 1,
            author: '曹雪芹',
            name: '红楼梦',
            price: 32.0
        }, {
            id: 2,
            author: '施耐庵',
            name: '水浒传',
            price: 30.0
        }, {
            id: '3',
            author: '罗贯中',
            name: '三国演义',
            price: 24.0
        }, {
            id: 4,
            author: '吴承恩',
            name: '西游记',
            price: 20.0
        }]
    }
 });

　　data 中是一些初始的数据，可以随意填写。

3 、将各种指令添加到 HTML

　　我们说过，vue 的核心聚焦在视图层，所以指令是最重要的一步，我们一点一点说。

　　不过因为指令分布的比较乱，所以直接附上全部代码，然后我一个一个的解释。

                <div id="app">
                    <table class="table table-hover">
                          <caption></caption>
                        <thead>
                            <tr>
                                <th>序号</th>
                                <th>书名</th>
                                <th>作者</th>
                                <th>价格</th>
                                <th>操作</th>
                            </tr>
                        </thead>
                        <tbody>
                            <tr v-cloak v-for="book in books"> 
                                <td>{{book.id}}</td>
                                <td>{{book.name}}</td>
                                <td>{{book.author}}</td>
                                <td>{{book.price}}</td>
                                <template v-if="book.id%2==0">
                                    <td class="text-left">

                                        <button type="button" class="btn btn-success" @click="updateBook(book)">修改</button>
                                    </td>
                                </template>
                                <template v-else>
                                    <td class="text-left">

                                    </td>
                                </template>
                            </tr>
                        </tbody>
                    </table>

　　首先，将 id 为 app 的 vue 实例挂载到 DOM 节点上，如果对于这些基本内容还不了解的话，可以去看我的上一篇博客，详细的介绍了关于 vue 的基础知识。

　　下面的表格，在 tr 中通过一个 v-for 循环，将 vue 实例 data 中的数据，全部载入到表格里。

　　细心的读者应该发现了，我在 v-for 前写了一个 v-cloak，这是干什么的呢？

　　用过 angular，vue 这种框架的人应该都知道，当我们用 {{}} 绑定数据的时候，当页面刷新的瞬间，会看到闪烁而过的原始代码。

　　当信息量比较大的时候，这种体验无疑是十分恶劣的，这个时候，v-cloak 这个指令保持在元素上直到关联实例结束编译。

　　和 CSS 规则如 [v-cloak] { display: none } 一起用时，这个指令可以隐藏未编译的 Mustache 标签直到实例准备完毕。

　　这样就解决了刷新的瞬间页面出现大量乱码的情况。

　　下面的 v-if 和 v-else 就是为了练习一下各种指令啦，让我们的按钮生成的时候可以轮流生成两种颜色 ~

　　而 v-model 是为了在 input 中输入内容时，可以动态的取到输入的内容。

　　还是那句话，这些基本指令不认识的话，可以去我的上一篇博客查看。

　　那些 v-on:click 绑定的函数，一会一个一个详细解释，现在先来看一下效果。

　　还不错吧 ~ 接下来我们就开始说一下各个函数。

addBook: function() {
            //计算书的 id
            this.book.id = this.books.length + 1;
            this.books.push(this.book);
            //将 input 中的数据重置
            this.book = {};}

　　这个是添加函数，大家可以去上面看一下 vue 实例中 data 里面的代码。

　　其实就只是这么几行代码，vue 的强大就已经展现的淋漓尽致了。

　　因为我们在输入框中绑定了 v-model，所以我们输入的内容就会动态的与 book 这个对象同步。

　　这个函数的原理就是给 book 那个对象的 id 赋值，然后将通过 v-model 动态绑定到输入框上的数据，也就是我们输入的数据，push 进 books 那个数组。

　　最后将 book 对象清空，也就是把我们的输入框清空了。

　　区区 3 行代码，信息的录入就完成了，是不是很神奇呢。

　　哦对了，在 vue 实例中，this 指向的就是本身这个 vue 实例，对面向对象的概念没有了解的话，建议百度一下 this 指向问题。

　　下面看一下删除　　

delBook: function(book) {
            var blength = this.books.length;
            this.books.splice(book.id-1, 1);
            for( var i = 0; i < blength ; i++) {
                if(book.id < this.books[i].id) {    
                    this.books[i].id -= 1;
                }
            }  
        }

　　删除的原理是取到当前 books 数组的长度，当前选中的那一条的下标是它的 id-1，用 splice 方法将它删除。

　　然后通过循环，将 id 比被删除数据大的那些项的 id 都减去 1，保持序号的连续。

　　然后是修改

        updateBook: function(book) {
            $("#add-book").css("display","none");
            $("#update-book").css("display","block");
            id = book.id;
        },
        updatesBook:function(book) {
            this.book.id = id;
              this.books.splice(id-1,1,this.book);
              $("#add-book").css("display","block");
            $("#update-book").css("display","none");
            this.book = {};

　　第一个函数就是将修改框弹出来，把添加的框隐藏掉，然后把需要修改的 id 绑定到一个全局的变量上 ~

　　然后第一个函数才是真正的修改命令。

　　将刚才绑定的全局变量，赋值给当前 id，然后还是用 splice 方法，用输入的内容把原来的内容替换掉 ~

　　然后还是同样的，将 book 对象也就是输入框清空。

结尾

　这样一个简单的信息录入平台就完成了，虽然代码不多，但是足以让我们深深感受到 vue 的强大。

　未来页面的发展趋势，一定是绕不开这样的设计思路的。

　下一期为大家带来一个拼图游戏，感兴趣的可以深入了解一下 vue 的系统。
