关于前端:uniapp使用原生小程序挂载的方法以支付宝营销组件mkt为例

用uni-app构建的支付宝小程序，要用营销组件mkt

   <!-- #ifdef MP-ALIPAY -->    <mkt        mode="AUTOMATIC"        boothCode="MERCHANT_SELF_TINYAPP"        onError="onError" onRender="onRender" onApplySuccess="onApplySuccess"    />    <!-- #endif -->

间接在methods外面写onError，onRender，onApplySuccess办法将获取不到回调
解决办法
在onload外面写

  this.$scope.onRender = this.onRender.bind(this)  this.$scope.onApplySuccess = this.onApplySuccess.bind(this)  this.$scope.onError = this.onError.bind(this)

 methods: {      onError (e) {        console.log('mktError2',e)      },      onRender (e) {        console.log('onRender2',e)      },      onApplySuccess (e) {        console.log('onApplySuccess2',e)      },}

这样就能获取到回调了
