040、Vue3+TypeScript基础,使用nanoid库生成id

01、使用powershell,输入npm i nanoid来安装:

 02、App.vue代码如下:

<template>
  <div class="app">
    <h2 class="title">App.Vue</h2>
    <Page1/>
    <br>
    <Page2/>
  </div>
</template>

<script lang="ts" setup name="App">
import Page1 from "@/view/Page1.vue";
import Page2 from "@/view/Page2.vue";
</script>

<style scoped>
.app {
  background-color: #ddd;
  box-shadow: 0 0 10px;
  border-radius: 10px;
  padding: 20px;
}

.nav-button {
  display: inline-block; /* 让链接显示为块级元素,以便应用宽度和高度 */
  padding: 10px 20px; /* 内边距 */
  margin: 0 5px; /* 外边距,用于按钮之间的间隔 */
  text-decoration: none; /* 移除下划线 */
  color: white; /* 文本颜色 */
  background-color: #007bff; /* 背景颜色 */
  border-radius: 5px; /* 边框圆角 */
  transition: background-color 0.3s; /* 平滑过渡效果 */
}

.nav-button:hover {
  background-color: #0056b3; /* 鼠标悬停时的背景颜色 */
}

.nav-button.router-link-active {
  background-color: #28a745; /* 当前激活(路由匹配)时的背景颜色 */
}

.mai-content {
  /* 添加边框样式 */
  border: 2px solid #000; /* 边框宽度、样式和颜色 */
  border-radius: 5px; /* 可选:添加边框圆角 */
  padding: 20px; /* 可选:给内部内容添加一些内边距 */
  margin: 20px; /* 可选:给元素添加一些外边距,以便与其他元素隔开 */
}
</style>

03、Page1.vue代码如下:

<template>
  <div class="mypage">
    <h2>当前求和为:{{ sum }}</h2>
    <select v-model="n">
      <option :value="1">1</option>
      <option :value="2">2</option>
      <option :value="3">3</option>
    </select>
    <button @click="add"></button>
    <button @click="min"></button>
  </div>
</template>

<script lang="ts" name="page1" setup>
import {ref} from "vue";

let sum = ref(1);
let n = ref(1);

function add() {
  sum.value += n.value;
}

function min() {
  sum.value -= n.value;
}
</script>

<style scoped>
.mypage {
  background-color: #ddd;
  box-shadow: 0 0 10px;
  border-radius: 10px;
  padding: 20px;

  button {
    margin: 0 5px;
  }
}
</style>

03.Page3.vue代码如下:

<template>
  <div class="mypage">
    <button @click="getLoveTalk">获取土味情话</button>
    <ul>
      <li v-for="talk in talklist" :key="talk.id">{{ talk.id }} -- {{ talk.title }}</li>
    </ul>
  </div>
</template>

<script lang="ts" name="page2" setup>
import {reactive} from "vue";
import axios from "axios";
import {nanoid} from "nanoid";

let talklist = reactive([
  {id: 'a001', title: '1今天你想我了没'},
  {id: 'a002', title: '2今天你想我了没'},
  {id: 'a003', title: '3今天你想我了没'},
])

async function getLoveTalk() {
  // 调用接口,获取情话
  let result = await axios.get(
      'https://api.uomg.com/api/rand.qinghua?format=json')
  let obj = {id: nanoid(), title: result.data.content}
  talklist.unshift(obj)
}
</script>
<style scoped>
.mypage {
  background-color: #ddd;
  box-shadow: 0 0 10px;
  border-radius: 10px;
  padding: 20px;

  button {
    margin: 0 5px;
  }
}
</style>

04、效果如下:
