- 预期表现
不应报错
- 复现路径


- 提供一个最简复现 Demo
chooseAddress:function(){
var that = this
wx.chooseAddress({
success:function(res){
var trade_addr =
res.provinceName +
res.cityName +
res.countyName +
res.detailInfo+" "
res.userName+"收 "
"电话:" + res.telNumber
"邮编:" + res.postalCode
var buyerInfoStr = "{" +
"\"userName\":\"" + res.userName + "\"," +
"\"postalCode\":\"" + res.postalCode + "\"," +
"\"provinceName\":\"" + res.provinceName + "\"," +
"\"cityName\":\"" + res.cityName + "\"," +
"\"countyName\":\"" + res.countyName + "\"," +
"\"detailInfo\":\"" + res.detailInfo + "\"," +
"\"nationalCode\":\"" + res.nationalCode + "\"," +
"\"telNumber\":\"" + res.telNumber + "\"" +
"}"
that.setData({
trade_addr: trade_addr,
buyerInfo: JSON.parse(buyerInfoStr)
})
console.log(that.data.buyerInfo)
}
})
}

微信小程序开发问题解答

微信小程序开发者回答：

希望尽快吧，强迫症看到bug咬牙启齿

微信小程序开发者回答：

嗯，开发者工具在 v2.4.4 和 v2.5.0 的基础库中只要发生切后台的行为，都会产生这个错误。真机上不会产生这个错误。我们会在下个基础库版本中进行修复。
