### 前言 ###

![3a7c8820d31bc5d410ef41314a3055cc.png][]vant ui有h5版和微信小程序版。其h5版只能用于h5，其微信小程序版[（vant weapp）][vant weapp]可用于微信和App，从![b2b8703d44461698bd23eae195beb86e.png][]uni-app 2.4.7起，H5和QQ小程序也支持了微信小程序组件。

### 使用步骤 ###

下载代码

*  在项目根目录下新建 `wxcomponents` 目录 ，此目录应该与`components` 目录同级。
 *  直接通过 `git` 下载 `vant-weapp` 最新源代码，并将`dist`目录拷贝到新建的`wxcomponents`目录下，并重命名`dist`为`vant-weapp`。
 *  在pages.json的globalStyle中 引入所需要的组件

<template>
      <div>
        <van-picker
          v-if="flag"
          :columns="columns"
          @change="changePicker"
        />
        <van-button @click="show">显示</van-button>
      </div>
    
    </template>
    
    <script>
    export default {
      data() {
        return {
          columns: ["杭州", "宁波", "温州", "嘉兴", "湖州"],
          flag: false
        };
      },
      methods: {
        show() {
          console.log("1 =", "show");
          this.flag = !this.flag;
        },
        changePicker(event) {
          console.log("1 =", event);
        }
      }
    };
    </script>

### 注意事项 ###

Vant组件中`Notify` 消息提示比较特殊

不仅需要在pages.json的globalStyle中 引入还需要再main.js中添加到vue原型上

//main.js
    
    import Notify from './wxcomponents//vant/notify/notify';
    
    Vue.prototype.$notify = Notify

然后在页面中使用

<template>
        <view>
            <van-button @click="showNotify">弹出提示</van-button>
     	<van-notify id="van-notify" />
        </view>
    </template>
    
    <script>
    export default {
      methods: {
        showNotify() {
           this.$notify({ type: "danger", message: "通知内容" });
        }
      }
    };
    </script>

### ***综上所述：*** ###

首先我不是在 [官网下载][Link 1] 的组件库，而是在这里 [https://ext.dcloud.net.cn/plugin?id=302][https_ext.dcloud.net.cn_plugin_id_302]，直接下载到了HBuilderX里面。因为官网下载的组件库没有做如何兼容处理，强拉取整合会出现很过错误，整合成本大，可以去 [uni官网][uni] 搜索下载 [Vantui Weapp For Uni-app][https_ext.dcloud.net.cn_plugin_id_302]
