vant组件库的使用 - - - vue篇&小程序篇

vue篇官方文档

创建好vue项目后
使用

npm install vant

安装 vant 组件库
安装好后

组件引入方法

一、全局引入（引入所有组件会增加代码包体积，官方不推荐）

在 main.js 文件中添加上

import Vant from "vant"
import 'vant/lib/index.css';
Vue.use(Vant)
在其他vue文件可以直接使用
<van-button type="default>默认按钮</van-button>

二、单个文件引入

直接在vue文件里添加

import Button from 'vant/lib/button';
import 'vant/lib/button/style';
注册一下 Button 组件
然后可以直接使用
<Button type="default">默认按钮</Button>

三、局部组件引入

在main.js中添加

import { Button } from 'vant';
import 'vant/lib/index.css';
这个是全部的,分细些就是
import "vant/lib/button/style;
Vue.use(Button);
在其他vue文件可以直接使用
<van-button type="default">默认按钮</van-button>

四、自动按需引入插件（官方推荐）

不会用,没看懂官方文档

小程序篇官方文档

创建项目后
打开终端
使用

npm init

初始化组件库
然后使用

npm i @vant/weapp -S --production

安装Vant Weapp
点击上方导航栏 - - - 工具 - - - 构建npm
完成后会生成一个 miniprogram_npm 这个玩意
然后右上角 - - - 详情里的使用npm模块勾上
然后就可以引入组件了

组件引入方法

一、全局引入

在 app.json 文件加入
"usingComponents": {
    "van-button": "/miniprogram_npm/@vant/weapp/button"
}
"usingComponents" 内为要使用的组件
然后在 wxml 直接使用即可
<van-button type="default">默认按钮</van-button>

这个应该挺全的
app.json文件加
"usingComponents": {
    "van-action-sheet": "./miniprogram_npm/@vant/weapp/action-sheet/index",
    "van-area": "./miniprogram_npm/@vant/weapp/area/index",

    "van-calendar": "./miniprogram_npm/@vant/weapp/calendar/index"
},
app.wxss文件加
  @import '/miniprogram_npm/@vant/weapp/common/index.wxss';

二、局部引入

在需要使用组件的页面的json文件的 "usingComponents" (使用组件)内加入想要使用的组件即可
{
  "usingComponents": {
    "van-button": "/miniprogram_npm/@vant/weapp/button"
  }
}
然后在 wxml 里就可以使用了
<van-button type="default">默认按钮</van-button>
