#Third, the html between Code

<center><h3>欢迎来到微信jsapi测试界面-V型知识库</h3></center>
    <p class="lbox_close wxapi_form">
     <h3 id="menu-shopping">微信小店接口</h3>
      <span class="desc">跳转微信商品页接口</span>
      <button class="btn btn_primary" id="openProductSpecificView">openProductSpecificView</button>

function

##

wx.config({
