相干配置

  1. 微信js文件版本大于等于1.6.0
    https://res.wx.qq.com/open/js/jweixin-1.6.0.js

  2. 微信受权配置

    window.wx.config({ ...otherConfig, openTagList: ['wx-open-launch-weapp']})

  3. 调用示例

    const style = {  position: 'absolute',  top: 0,  right: 0,  bottom: 0,  left: 0,};function OpenWeapp({ originId, pagePath }) {  return ( <wx-open-launch-weapp username={originId} path={pagePath} style={style}>   <script type="text/wxtag-template">     <div style={style} />   </script> </wx-open-launch-weapp>  );}// 应用形式<div style={{ position: 'relative' }}>点击跳转小程序<OpenWeapp originId="gh_xxxxxxxx" pagePath="pages/home/index?user=123&action=abc" /></div>

为什么给div增加position: relative呢？

因为wx-open-launch-weapp设置款式比拟艰难，故放弃设置款式，将wx-open-launch-weapp作为一个通明的占位元素，撑满父元素，也能达到预期的性能
