记账是管理个人财务的重要工具,它可以帮助用户跟踪收入和支出,了解资金流向,并做出明智的财务决策。本篇技术博客将指导你使用 Vue.js 构建一个全面的记账应用,它具有以下功能:
该记账应用的核心功能包括:
1. 数据管理
使用 Vuex 状态管理库管理应用程序数据。创建 store.js
文件,定义 state
、getters
、mutations
和 actions
:
import Vue from "vue";
import Vuex from "vuex";
Vue.use(Vuex);
export default new Vuex.Store({
state: {
incomes: [],
expenses: [],
},
getters: {
totalIncome(state) {
return state.incomes.reduce((acc, curr) => acc + curr.amount, 0);
},
totalExpense(state) {
return state.expenses.reduce((acc, curr) => acc + curr.amount, 0);
},
},
mutations: {
addIncome(state, income) {
state.incomes.push(income);
},
addExpense(state, expense) {
state.expenses.push(expense);
},
},
actions: {
addIncome({ commit }, income) {
commit("addIncome", income);
},
addExpense({ commit }, expense) {
commit("addExpense", expense);
},
},
});
2. 图表展示
使用 ECharts 库生成图表。在 main.js
文件中导入 ECharts:
import * as echarts from "echarts";
在 App.vue
组件中,使用 ECharts
组件创建饼图和折线图:
<template>
<div>
<ECharts :options="options" style="width: 100%; height: 300px;"></ECharts>
</div>
</template>
<script>
import { ref } from "vue";
import * as echarts from "echarts";
export default {
setup() {
const options = ref({
title: {
text: "财务状况",
},
tooltip: {
trigger: "item",
},
legend: {
data: ["收入", "支出"],
},
series: [
{
name: "收入",
type: "pie",
data: [
{ value: 100, name: "工资" },
{ value: 50, name: "兼职" },
],
},
{
name: "支出",
type: "pie",
data: [
{ value: 50, name: "餐饮" },
{ value: 30, name: "交通" },
],
},
],
});
return {
options,
};
},
};
</script>
3. 记账功能
使用 Vue Formulate 库创建用户友好的记账表单。在 AddTransaction.vue
组件中,使用 Form
和 Input
组件构建表单:
<template>
<Form @submit.prevent="onSubmit">
<Input v-model="transaction.amount" label="金额" type="number" required />
<Input v-model="transaction.category" label="类别" required />
<Input v-model="transaction.note" label="备注" />
<Button type="submit">提交</Button>
</Form>
</template>
<script>
import { ref } from "vue";
import { useStore } from "vuex";
export default {
setup() {
const transaction = ref({
amount: 0,
category: "",
note: "",
});
const store = useStore();
const onSubmit = () => {
if (transaction.amount > 0 && transaction.category) {
transaction.type = transaction.amount > 0 ? "income" : "expense";
store.dispatch("addTransaction", transaction);
transaction.amount = 0;
transaction.category = "";
transaction.note = "";
}
};
return {
transaction,
onSubmit,
};
},
};
</script>
4. 备注和附件
使用 Wangeditor 库添加富文本编辑器,允许用户为收支添加备注。在 AddTransaction.vue
组件中,使用 Editor
组件:
<template>
<Form @submit.prevent="onSubmit">
<!-- 其他代码 -->
<Editor v-model="transaction.note" placeholder="请输入备注" />
<!-- 其他代码 -->
</Form>
</template>
<script>
import { ref } from "vue";
import { useStore } from "vuex";
import { Editor } from "@wangeditor/editor-for-vue";
export default {
setup() {
const transaction = ref({
amount: 0,
category: "",
note: "",
});
const store = useStore();
return {
transaction,
onSubmit,
Editor,
};
},
};
</script>
5. 数据导出
使用 FileSaver 库导出收支数据。在 App.vue
组件中,添加导出按钮:
<template>
<div>
<!-- 其他代码 -->
<Button @click="exportData">导出数据</Button>
</div>
</template>
<script>
import { ref } from "vue";
import { useStore } from "vuex";
import FileSaver from "file-saver";
export default {
setup() {
const store = useStore();
const exportData = () => {
const data = JSON.stringify(store.state);
const blob = new Blob([data], { type: "application/json" });
FileSaver.saveAs(blob, "transactions.json");
};
return {
exportData,
};
},
};
</script>
本篇技术博客提供了分步指南,指导你使用 Vue.js 构建一个全面的记账应用。该应用具有数据管理、图表展示、记账功能、备注和附件以及数据导出等核心功能。
未来,该记账应用可以进一步拓展和优化,例如:
