1. 安装vue项目 npm init webpack project
2 安装iview npm i iview --save (这里是结合iview框架使用的 可根据自己的需求安装 当然也可以不安装)
3 在src目录下建一个utils文件夹 里面需要放5个js 都是封装好的js文件 功能不仅仅局限于加密 可以研究一下 你会学到很多东西
1.api.js
/** * 为vue实例添加http方法 * vue.use(http) */ import http from './http' export default { /** * install钩子 * @param {vue} vue vue */ install (vue) { vue.prototype.http = http } }
2. filters.js
// 公共使用的filters
import vue from 'vue';
import {gettime, getprdtype} from '../utils/time';
// 区分支付方式的filter
vue.filter('paywaytype', function (value) {
return value;
});
// 时间
vue.filter('newdate', function (value) {
return gettime(value);
});
// 时间-分钟
vue.filter('minute', function (str, n) {
const num = parseint(n);
return str.split(' ')[num];
});
// 分割以：连接多个参数的string
vue.filter('valstr', function (str, n) {
const num = parseint(n);
return str.split(':')[num];
});
// 根据提供时间计算倒计时
vue.filter('countdown', function (str) {
const datestr = new date(str).gettime();
const timenow = new date().gettime();
const countdown = datestr - timenow;
const countdownday = math.floor((datestr - timenow) / 86400000);// 计算剩余天数
const countdownhour = math.floor((datestr - timenow) / 3600000 % 24);// 计算剩余小时
const countdownmin = math.floor((datestr - timenow) / 60000 % 60);// 计算剩余分钟
// const countdownsec = math.floor((datestr - timenow) / 1000 % 60);// 计算剩余秒
if (countdown <= 0) {
return '- - - -';
} else {
return countdownday + '天' + countdownhour + '小时' + countdownmin + '分钟';
}
});
// 取绝对值
vue.filter('numberfn', function (numberstr) {
return math.abs(numberstr);
});
// 处理图片地址的filter
vue.filter('imgsrc', function (src) {
const env = getprdtype();
switch (env) {
case 'pre':
return `https://preres.bldz.com/${src}`;
case 'pro':
return `https://res.bldz.com/${src}`;
case 'test':
default:
return `https://testimg.bldz.com/${src}`;
}
});
// 直接转化剩余时间
vue.filter('dateshow', function (datestr) {
const countdownday = math.floor(datestr / 86400);// 计算剩余天数
const countdownhour = math.floor(datestr / 3600 % 24);// 计算剩余小时
const countdownmin = math.floor(datestr / 60 % 60);// 计算剩余分钟
// const countdownsec = math.floor((datestr - timenow) / 1000 % 60);// 计算剩余秒

} else if (countdownday <= 0) {
return countdownhour + '小时' + countdownmin + '分钟';
} else {
return countdownday + '天' + countdownhour + '小时' + countdownmin + '分钟';
}
});
// 处理图片
vue.filter('imglazy', function (src) {
return {
src,
error: '../static/images/load-failure.png',
loading: '../static/images/default-picture.png'
};
});

4.配置main.js
import vue from 'vue'
import app from './app'
import router from './router'
import vuerouter from 'vue-router';
import iview from 'iview';
import 'iview/dist/styles/iview.css'
import http from './utils/http'
import api from './utils/api'
import utils from './utils/utils'
import './utils/filters'
vue.config.productiontip = false
vue.use(vuerouter);
vue.use(iview);
vue.use(http)
vue.use(api)
vue.use(utils)
/* eslint-disable no-new */
global.base_url = process.env.api_host
new vue({
el: '#app',
router,
components: { app },
template: '<app/>'
})
5.找到config文件夹下的dev.env.js
module.exports = merge(prodenv, {
node_env: '"development"',
api_host: '"开发环境接口地址"'
})
6.页面中具体使用方法
<template>
<div class="hello">
<select v-model="model8" clearable style="width:200px">
<option v-for="item in citylist" :value="item.productcode" :key="item.productcode">{{item.productname }}</option>
</select>
</div>
</template>
<script>
export default {
name: 'helloworld',
data () {
return {
citylist:[],
model8:"code"
}
},
mounted(){
this.http
.post(base_url + "请求路径",{})
.then(data => {
if (data.code == "success") {
this.citylist = data.data;
this.citylist.splice(0,0,{ productcode: "code", productname: "所有产品" })
}
})
.catch(err => {
console.log(err);
});
}
}
</script>
<style scoped>
</style>
