篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Vue2.0 + Element-UI + WebAPI实践：简易个人记账系统相关的知识，希望对你有一定的参考价值。
最近正在学习Vue2.0相关知识，正好近期饿了么桌面端组件Element-UI发布，便动手做了一款简易个人记账系统，以达到实践及巩固目的。
1.开发环境
Win10 + VS2015 + Sqlserver2008R2 + WebAPI + Dapper + Vue2.0 + Element-UI
2.项目解决方案概览
简单介绍下，Account是WebAPI项目，承载前端请求；Account.BLL、Account.DAL、Account.Entity不废话；Account.Common是对Dapper及Log4net等简单封装；KnockoutFE是较早时候弄的一个基于Bootstrap + Knockout的前端；VueFE是主角，待会儿重点介绍。

3.前端实现
初始界面：
1.左边导航部分
使用el-menu + vue-router实现：
<div id="sideBar"> <!--<ul> <router-link to="/manifests" tag="li">日消费明细</router-link> <router-link to="/daily" tag="li">日消费清单</router-link> <router-link to="/monthly" tag="li">月消费清单</router-link> <router-link to="/yearly" tag="li">年消费清单</router-link> </ul>--> <el-menu default-active="manifests" theme="dark" v-bind:router="true"> <el-menu-item index="manifests">日消费明细</el-menu-item> <el-menu-item index="daily">日消费清单</el-menu-item> <el-menu-item index="monthly">月消费清单</el-menu-item> <el-menu-item index="yearly">年消费清单</el-menu-item> </el-menu> </div>
注释掉部分是最开始时候没有采用el-menu组件导航，而是使用了vue-router自己的路由导航。
路由部分对应JS代码：
const router = new VueRouter({ routes: [ { name: "manifests", path: "/manifests", component: Manifests }, { name: "daily", path: "/daily", component: Daily }, { name: "monthly", path: "/monthly", component: Monthly }, { name: "yearly", path: "/yearly", component: Yearly } ] });
其中，Manifests、Daily、Monthly、Yearly分别代表日消费明细、日消费清单、月消费清单、年消费清单自定义Vue组件。
2.具体内容页组件实现
这里以日消费明细组件为例来详细介绍，里边囊括了CRUD。
组件完整定义：
/// <reference path="index.js" /> /// <reference path="vue.js" /> /// <reference path="vue-resource.js" /> /// <reference path="util.js" /> const Manifests = { template: "#manifests", created: function () { this.fetchData(); }, data: function () { let currentDate = new Date(); let costValidator = (rule, value, callback) => { if (!/^[0-9]+(.[0-9]{2})?$/.test(value)) { callback(new Error("请输入合法金额")); } else { callback(); } }; return { start: new Date(currentDate.getFullYear(), currentDate.getMonth() - 3, 1), end: new Date(), manifests: [], title: "", manifest: {}, showOperateManifest: false, isAdd: false, rules: { Date: [ { type: "date", required: true, message: "请选择消费日期", trigger: "change" } ], Cost: [ { required: true, message: "请填写消费金额", trigger: "blur" }, { validator: costValidator, trigger: "change" } ], Remark: [ { required: true, message: "请填写消费明细", trigger: "blur" } ] }, pageIndex: 0, pageSize: 10, total: 0, pageSizes: [10, 20, 50, 100] } }, methods: { fetchData: function () { this.manifests = []; this.$http.get("http://localhost:1500/api/Manifests/paged", { params: { start: this.start.format("yyyy-MM-dd"), end: this.end.format("yyyy-MM-dd"), pageIndex: this.pageIndex, pageSize: this.pageSize } }) .then(response => { this.total = response.body.count; this.manifests = response.body.data; }) .catch(response => this.$alert(response.body.Message, "日消费明细", { type: "error" })); }, add: function () { this.title = "添加消费明细"; this.manifest = { ID: Guid.NewGuid().ToString("D"), Date: new Date(), Cost: "", Remark: "" }; this.isAdd = true; this.showOperateManifest = true; }, save: function () { this.$refs.formManifest.validate(valid => { if (valid) { let operateManifest = JSON.parse(JSON.stringify(this.manifest)); operateManifest.Date = this.manifest.Date.format("yyyy-MM-dd"); if (this.isAdd) { this.$http.post("http://localhost:1500/api/Manifests", operateManifest) .then(() => { this.manifests.push(operateManifest); this.showOperateManifest = false; bus.$emit("manifestChanged"); this.$message({ message: "添加成功", type: "success" }); }) .catch(err => { //console.log(err); this.$alert(err.body.Message, "添加日消费明细", { type: "error" }); }); } else { this.$http.put("http://localhost:1500/api/Manifests", operateManifest) .then(response => { let updatedManifest = this.manifests.find(x => x.ID == this.manifest.ID); updatedManifest.Date = operateManifest.Date; updatedManifest.Cost = operateManifest.Cost; updatedManifest.Remark = operateManifest.Remark; this.showOperateManifest = false; bus.$emit("manifestChanged"); this.$message({ message: "修改成功", type: "success" }); }) .catch(err => { //console.log(err); this.$alert(err.body.Message, "修改消费明细", { type: "error" }); }); } } else { return false; } }); }, cancel: function () { this.manifest = {}; this.showOperateManifest = false; }, edit: function (ID) { let currentManifest = this.manifests.find(x => x.ID == ID); this.manifest = JSON.parse(JSON.stringify(currentManifest)); this.manifest.Date = new Date(this.manifest.Date); this.title = "编辑消费明细"; this.isAdd = false; this.showOperateManifest = true; }, del: function (ID) { this.$confirm("是否删除？", "警告", { type: "warning" }) .then(() => { this.$http.delete("http://localhost:1500/api/Manifests/" + ID) .then(response => { let index = this.manifests.findIndex(x => x.ID == ID); this.manifests.splice(index, 1); bus.$emit("manifestChanged"); this.$message({ message: "删除成功", type: "success" }); }) .catch(err => { this.$alert(err.body.Message, "删除消费明细", { type: "error" }); //console.log(err); }); }); }, dialogClosed: function () { this.$refs.formManifest.resetFields(); }, sizeChange: function (pageSize) { this.pageSize = pageSize; this.fetchData(); }, pageIndexChange: function (pageIndex) { this.pageIndex = pageIndex; this.fetchData(); } } }
组件对应的模板定义：
<script type="text/x-template" id="manifests"> <div> <div> 开始日期： <el-date-picker v-model="start" type="date" placeholder="选择日期"></el-date-picker> 结束日期： <el-date-picker v-model="end" type="date" placeholder="选择日期"></el-date-picker> <el-button type="primary" size="small" v-on:click="fetchData" icon="search">查 询</el-button> <el-button type="primary" size="small" v-on:click="add" icon="plus">添 加</el-button> </div> <div class="table"> <el-table v-bind:data="manifests" highlight-current-row border height="500"> <el-table-column prop="Date" label="日期"></el-table-column> <el-table-column prop="Cost" label="金额"></el-table-column> <el-table-column prop="Remark" label="备注"></el-table-column> <el-table-column inline-template label="操作"> <span> <el-button type="text" size="small" v-on:click="edit(row.ID)" icon="edit">编 辑</el-button> <el-button type="text" size="small" v-on:click="del(row.ID)" icon="delete">删 除</el-button> </span> </el-table-column> </el-table> </div> <div class="pager"> <el-pagination v-bind:current-Page="pageIndex" v-bind:page-size="pageSize" :total="total" layout="total,sizes,prev,pager,next,jumper" v-bind:page-sizes="pageSizes" v-on:size-change="sizeChange" v-on:current-change="pageIndexChange"> </el-pagination> </div> <div> <el-dialog v-bind:title="title" v-bind:close-on-click-modal="false" v-model="showOperateManifest" v-on:close="dialogClosed"> <el-form v-bind:model="manifest" v-bind:rules="rules" ref="formManifest" label-position="left" label-width="80px"> <el-form-item label="日 期" prop="Date"> <elVue2.0 + Element-UI + WebAPI实践：简易个人记账系统
