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:

复制代码

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:

复制代码 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 } ] }); 复制代码 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: 复制代码 /// /// /// ///

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(); } } } 复制代码 组件对应的模板定义: 复制代码

查询部分 :

复制代码

这里关于事件处理绑定,官网推荐简写的@click,但这里没有采用,而是使用了完整绑定V-on:click,因为考虑到以后可能会和Razor整合,@符可能会冲突

查询JS:

复制代码 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" })); } 复制代码

API请求采用了Vue开源社区的vue-resource,简单轻便,再搭配ES6 Promise,写起来很顺手。

添加/编辑的实现:

这里使用了el-dialog嵌套el-form

复制代码 确 定 取 消 复制代码 复制代码 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; } }); } 复制代码

其中包括了表单验证部分,也是采用Element-UI文档中介绍的验证方式,目前有些验证支持不是很好,比如number,可能是哪里用的不对吧,所以上边对金额部分采取了正则自定义验证。

底部分页部分:

 </el-pagination>

如上所示,直接使用了饿了么分页组件,设置几个属性, 再绑定几个JS属性、分页事件处理程序即可,十分方便

Vue Date对象中分页相关的属性:

页索引及分页大小变动事件处理:

复制代码 sizeChange: function (pageSize) { this.pageSize = pageSize; this.fetchData(); }, pageIndexChange: function (pageIndex) { this.pageIndex = pageIndex; this.fetchData(); } 复制代码 没什么特别, 根据最新页索引或页尺寸大小从新拉取一遍数据就行了。
