一、前期准备工作

软件环境：微信开发者工具

官方下载地址：https://mp.weixin.qq.com/debug/wxadoc/dev/devtools/download.html

1、基本需求。

• 实现一维条码，二维码的快速生成

2、案例目录结构

二、程序实现具体步骤

1.条码index.wxml代码

<!--index.wxml-->

<view class="container page">

  <view class="panel">

    <view class="header">

    </view>

    <view class="barcode">

      <view class="barnum">{{code}}</view>

      <canvas canvas-id="barcode" />

    </view>

    <view class="qrcode">

      <canvas canvas-id="qrcode" />

    </view>

  </view>

</view>

2.条码index.wxss代码

/**index.wxss**/

page {

    background-color: #439057;

}

.page {

    display: flex;

    flex-direction: column;

    justify-content: center;

    align-items: center;

}

.container {

	padding-bottom: 10rpx;

}

.panel {

    display: flex;

    flex-direction: column;

    justify-content: space-between;

    align-items: stretch;

    box-sizing: border-box;

    width: 710rpx;

    margin-top: 40rpx;

    border-radius: 10rpx;

    background-color: #fff;

}

.header {

    height: 140rpx;

    background-color: #f0f0f0;

    border-radius: 10rpx 10rpx 0 0;

}

.barcode {

    display: flex;

    height: 320rpx;

    flex-direction: column;

    justify-content: center;

    align-items: center;

}

.barnum {

    width: 670rpx;

    height: 100rpx;

    line-height: 100rpx;

    font-size: 38rpx;

    font-weight: bold;

    text-align: center;

    letter-spacing: 10rpx;

    white-space: nowrap;

}

.barcode > canvas {

    width: 680rpx;

    height: 200rpx;

}

.qrcode {

    height: 420rpx;

    display: flex;

    flex-direction: column;

    justify-content: flex-end;

    align-items: center;

}

.qrcode > canvas {

    width: 420rpx;

    height: 420rpx;

}

3.条码index.js逻辑代码

//index.js

var wxbarcode = require('../../utils/index.js');

Page({

    data: {

        code: 'http://blog.geekxz.com'

    },

    onLoad: function() {

        wxbarcode.barcode('barcode', 'http://blog.geekxz.com', 680, 200);

        wxbarcode.qrcode('qrcode', 'http://blog.geekxz.com', 420, 420);

    }

})
