Introduce error handling on loadImage

[desytech]

Is there any reason to resolve the loadImage promise even if some image failed loading? Need some identification on my project if there is a failure on image loading. I was not able to add a pull request. Put my changes in this issue.

能有重现的例子么?

是偶尔出现的，目前100条数据，也就出现了5次左右，返回的code是正常的，就是name不对； 代码如下： location.changeLocation(selectSsq[0], selectSsq[1], selectSsq[2]); let selectLocation = location.getCurrentAddress(); formData.provinceCode = selectLocation.province.code; formData.provinceName = selectLocation.province.name; formData.cityCode = selectLocation.city.code; formData.cityName = selectLocation.city.name; formData.areaCode = selectLocation.district.code; formData.areaName = selectLocation.district.name;

出现错误的是哪些城市/区错了？直接调方法100次，还是通过页面联动点击那种？

[sesntt]

通过页面联动，在提交数据时，获取到选择的省市区code，再执行我发的那段代码，获取省市区名字，目前遇到出现错误的有： 陕西省/新城区/新城区、江苏省/海陵区/海陵区、江苏省/鼓楼区/鼓楼区、安徽省/镜湖区/镜湖区、贵州省/南明区/南明区、广东省/香洲区/香洲区、北京市/东城区/东城区

以上城市/区是偶尔出现，不是每次都出现

试了几次重现不了 😅
