- 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)

}

})

}
