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。
Win10 + VS2015 + Sqlserver2008R2 + WebAPI + Dapper + Vue2.0 + Element-UI
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。

初始界面:
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。
这里以日消费明细组件为例来详细介绍,里边囊括了CRUD。

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:
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" }));
}
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
<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">
<el-date-picker v-model="manifest.Date"></el-date-picker>
</el-form-item>
<el-form-item label="金 额" prop="Cost">
<el-input v-model="manifest.Cost"></el-input>
</el-form-item>
<el-form-item label="备 注" prop="Remark">
<el-input v-model="manifest.Remark"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" v-on:click="save">确 定</el-button>
<el-button type="primary" v-on:click="cancel">取 消</el-button>
</el-form-item>
</el-form>
</el-dialog>
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;
}
});
}
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 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>
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:
sizeChange: function (pageSize) {
this.pageSize = pageSize;
this.fetchData();
},
pageIndexChange: function (pageIndex) {
this.pageIndex = pageIndex;
this.fetchData();
}
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。
