    • 移动组件代码

    执行 npm install @yidun/swan-ne-captcha(如已执行,可忽略)

    node_modules/@yidun/swan-ne-captcha 拷贝到 Taro 开发目录中,比如 components

    • 在页面配置文件中引入组件
    // index.json
    export default {
      usingComponents: {
        "ne-captcha": "../../components/swan-ne-captcha/dist/index"
      }
    }
    
    • 使用验证码组件
    // index.js
    import { Component } from 'react'
    import { View, Text, Button } from '@tarojs/components'
    import './index.scss'
    import { getCurrentInstance } from '@tarojs/taro'
    export default class Index extends Component {
    
      saveCaptchaRef = (node) => this.captchaIns = node
      componentWillMount () { }
      componentDidMount () { }
      componentWillUnmount () { }
      componentDidShow () { }
      componentDidHide () { }
      handleClick () {
        const { page } = getCurrentInstance()
        const ins = page.selectComponent(this.captchaIns.uid)
        ins.popup() // 常规验证码使用 ins.popup(), 智能无感知验证码调用 ins.verify()
      }
      handleVerify (ev) {
        // ev.detail 包含 validate 信息
      }
      render () {
        return (
          <View className='index'>
            <Button onClick={() => this.handleClick()}>验证码</Button>
            <View>
              <ne-captcha
                captchaId="业务id"
                width="640rpx"
                ref={this.saveCaptchaRef}
                onVerify={this.handleVerify}>
              </ne-captcha>
            </View>
          </View>
        )
      }
    }
