第二篇来快速讲解vue,以及设计个抽象js,没有抽象的js是无法完成高效率的

Vue每个页面的编写基本框架

<template>
//你的网页内容
</template>
<script setup>
//你的脚本内容
</script>
<style scoped>
//页面的css
</style>

抽象的js就和main.js放在同个文件内,我这里命名为function.js,其中我写的抽象库参考如下:

import { ref, onMounted, onUnmounted } from 'vue'
import axios from "axios";
import xmljs from 'xml-js';
import NProgress from 'nprogress';
import 'nprogress/nprogress.css'; // 导入NProgress的样式

// 按照惯例，组合式函数名以“use”开头
export function useMouse() {
    // 被组合式函数封装和管理的状态
    const x = ref(0)
    const y = ref(0)

    // 组合式函数可以随时更改其状态。
    function update(event) {
        x.value = event.pageX
        y.value = event.pageY
    }

    // 一个组合式函数也可以挂靠在所属组件的生命周期上
    // 来启动和卸载副作用
    onMounted(() => window.addEventListener('mousemove', update))
    onUnmounted(() => window.removeEventListener('mousemove', update))

    // 通过返回值暴露所管理的状态
    return { x, y }
}

export function nuotime() {
    const nowdate = ref(null)
    const currentTime = ref(null)
        setInterval(() => {
            const date = new Date();
            const hours = date.getHours();
            const minutes = date.getMinutes();
            const seconds = date.getSeconds();
            const year = date.getFullYear();
            const month = date.getMonth() + 1;
            const day = date.getDate();
            nowdate.value = year;
            currentTime.value = `${year}年${month}月${day}日 ${hours}时${minutes}分${seconds}秒`;
        }, 1000);
    return { nowdate, currentTime }
}

export function nuorequst(url) {
    const nuostatus = ref(200);
    const nuodata = ref(null);

    const get = () => {
        NProgress.start(); // 启动进度条

        axios.get(url)
            .then(response => {
                handleResponse(response);
            })
            .catch(error => {
                handleError(error);
            })
            .finally(() => {
                NProgress.done(); // 无论请求成功或失败都停止进度条
            });
    };

    const post = (data) => {
        NProgress.start(); // 启动进度条

        axios.post(url, data)
            .then(response => {
                handleResponse(response);
            })
            .catch(error => {
                handleError(error);
            })
            .finally(() => {
                NProgress.done(); // 无论请求成功或失败都停止进度条
            });
    };

    const handleResponse = (response) => {
        // 判断响应的Content-Type是否为XML
        const contentType = response.headers['content-type'];
        if (contentType && contentType.includes('xml')) {
            // 如果是XML，则将其解析为JSON
            const jsonResult = xmljs.xml2js(response.data, { compact: true, spaces: 4 });
            nuodata.value = jsonResult;
        } else {
            // 如果是JSON，则直接使用响应数据
            nuodata.value = response.data;
        }
        nuostatus.value = response.status;
    };

    const handleError = (error) => {
        nuostatus.value = error.response ? error.response.status : 500;
        nuodata.value = error.response ? error.response.data : error;
    };

    return { nuostatus, nuodata, get, post };
}

你需要安装以下内容(终端或cmd)

pnpm i axios
pnpm i nprogress
pnpm i xml-js

引用axios方法

<script setup>
import { nuorequst } from '@/function.js'
const { nuostatus, nuodata, get, post } = nuorequst('url')
//get方式
get(); 
//post方式
const postData = { canshu:'canshu' };
const fetchData = () => {
  post(postData);
};
</script>

引用时间方法

import { nuotime } from '@/function.js'
const { nowdate, currentTime } = nuotime()

与上面内容结合起来示例(api),其中v-if v-else是判断，想必写过代码的同学都很熟悉了，for循环和python也有很多相似之处。如果你想class类哪个标签带变量，就得加上一个冒号,如<a :href="nuodata.url"></a>

<template>
  <div class="nuoyis-api-main">
    <p v-if=" nuostatus===200 ">api接口名单请求状态:正常</p>
    <p v-else>api接口名单请求状态:异常<br/>请联系站长修复</p>
    <p v-if=" nuostatus===200 ">目前推出的API调用</p>
    <div class="nuoyis-api" id="nuoyis-api" v-if=" nuostatus===200 ">
        <router-link class="nuoyis-api-url" v-for="api in nuodata" :to="{ path:'/apiquery',query:{id:api.id}}">
        <i class="nuoyis-api-images"></i>
        <div class="nuoyis-api-text">
          <h2>{{ api.name }}</h2>
          <p>
            说明:无
            <br />
            状态:{{ api.state }}
          </p>
        </div>
      </router-link>
    </div>
  </div>
  <button @click="$router.push('/')" class="routerbtn">首页</button>
</template>
<script setup>
import nuotitle from '@/wabpages/nuotitle.vue'
import { nuorequst } from '@/function.js'
const { nuostatus, nuodata, get, post } = nuorequst('https://server-api.nuoyis.net/jiekou.json')
