Question

AngularJs（1）。我有2个HTML选择。每个select都使用ajax调用（$ http.get）

中的值

第一：

<option ng-repeat="lab in getLabels('A')" value="{{lab}}">{{lab}}</option>

第二：

<option ng-repeat="lab in getLabels('X')" value="{{lab}}">{{lab}}</option>

问题是因为ajax，getLabels返回一个promise，而不是一个直接列表。如何解决这个问题，知道我必须为2个选项中的每一个使用特定参数？

这是 my test pen （我使用＆＃34; $ q＆＃34;服务模拟ajax调用）

不要直接绑定。使用调解员:(更新！）像这样的Smth

Reload servers from a list of IPs

This script looks for a server with a determinate IP address and reload it from an image template.

print("The reload failed for these IPs:")
print(json.dumps(failedServers, sort_keys=True, indent=2, separators=(',', ': ')))

使用$ http.get获取select的值
