一.通过 Npm方式下载构建
1.下载和安装Npm：Npm https://docs.npmjs.com/downloading-and-installing-node-js-and-npm
或者 https://nodejs.org/en/download/
未安装npm 提示
以下以安装node安装包为例
按任意键继续
安装完成后
2. 下载和安装小程序开发工具 ：https://developers.weixin.qq.com/miniprogram/dev/devtools/download.html
3.安装使用weui
https://github.com/wechat-miniprogram/weui-miniprogram
3.1 在小程序根目录下初始化npm
按以下方式避免npm初始化报错
message： NPM packages not found. Please confirm npm packages which need to build are belong to `miniprogramRoot` directory. Or you may edit project.config.json's `packNpmManually` and `packNpmRelationList`
appid: wxfdcdeefd46e93725
openid: o6zAJs4UHtxoUdwBMYwoYl2bQM9Y
ideVersion: 1.06.2401020
osType: win32-x64
time: 2024-03-07 14:31:03 
根目录下初始化
npm init -y 
安装npm
npm install 
配置project.config.json文件
"packNpmManually": true,"packNpmRelationList": [{"packageJsonPath": "./package.json","miniprogramNpmDistDir": "./miniprogram/"}],
安装小程序weui npm包
npm install --save weui-miniprogram 
重新打开此项目
打开工具菜单=>构建npm
二.通过 useExtendedLib扩展库方式下载构建
1.通过微信开发者工具创建项目
2.配置项目根目录下app.json，添加如下内容:
"useExtendedLib": {"weui": true},
3.以官网-progress 进度条实例为例:
编辑index目录下 index.js
const app = getApp()Page({data: {},onLoad: function () {console.log('代码片段是一种迷你、可分享的小程序或小游戏项目，可用于分享小程序和小游戏的开发经验、展示组件和 API 的使用、复现开发问题和 Bug 等。可点击以下链接查看代码片段的详细文档：')console.log('https://mp.weixin.qq.com/debug/wxadoc/dev/devtools/devtools.html')},
})
编辑index目录下 index.wxml
<progress percent="20" show-info />
<progress percent="40" stroke-width="12" />
<progress percent="60" color="pink" />
<progress percent="80" active />
<progress percent="100" active />
编辑index目录下 index.wxml
progress {margin: 10px;}
编译运行即可
4.以官网-checkbox实例为例:
编辑index目录下 index.js
Page({data: {items: [{ name: 'USA', value: '美国' },{ name: 'CHN', value: '中国', checked: 'true' },{ name: 'BRA', value: '巴西' },{ name: 'JPN', value: '日本' },{ name: 'ENG', value: '英国' },{ name: 'TUR', value: '法国' },]},checkboxChange: function (e) {console.log('checkbox发生change事件，携带value值为：', e.detail.value)}
})编辑index目录下 index.json
{ "componentFramework": "glass-easel" }编辑index目录下 index.wxml
<checkbox-group bindchange="checkboxChange"><label class="checkbox" wx:for="{{items}}"><checkbox value="{{item.name}}" checked="{{item.checked}}"/>{{item.value}}</label>
</checkbox-group>编辑index目录下 index.wxss
.intro {margin: 30px;text-align: center;
}
page {margin-top: 80px;
}
.checkbox, checkbox {display: flex;flex-direction: row;height: 30px;line-height: 30px;
}
.checkbox {justify-content: center;
}编译预览
5.以官网-input实例为例:
编辑index目录下 index.js
Page({data: {focus: false,inputValue: '',placeholderStyle: {color:'#F76260'}},onLoad() {// 兼容console.log(this.renderer)if (this.renderer == 'skyline') {this.setData({placeholderStyle: {color:'#F76260'}})} else {this.setData({placeholderStyle: "color:#F76260"})}},bindKeyInput: function (e) {this.setData({inputValue: e.detail.value})},bindReplaceInput: function (e) {var value = e.detail.valuevar pos = e.detail.cursorvar leftif (pos !== -1) {// 光标在中间left = e.detail.value.slice(0, pos)// 计算光标的位置pos = left.replace(/11/g, '2').length}// 直接返回对象，可以对输入进行过滤处理，同时可以控制光标的位置return {value: value.replace(/11/g, '2'),cursor: pos}// 或者直接返回字符串,光标在最后边// return value.replace(/11/g,'2'),},bindHideKeyboard: function (e) {if (e.detail.value === '123') {// 收起键盘wx.hideKeyboard()}}
})编辑index目录下 index.js
{ "componentFramework": "glass-easel" }编辑index目录下 index.wxml
