AngularJS select default value with ng-model and ng-repeat instead ng-option
提问by amcdnl
I have the following code:
我有以下代码：
<select ng-model="model.RemediationCredentials" name="remediationCredential" id="remediationCredential">
<option value="0">---</option>
<option ng:repeat="cred in credentialsList"
data-index="{{$index}}" value="{{cred.Value}}">{{cred.Key}}</option>
</select>
and credentialsListlooks like:
和credentialsList看起来像：
credentialsList = [ { Key: "Panda", Value: "Zoo: } ]
I think I need to use ng-repeatvs ng-optionto do some basic things like the no selection and do the data-index. However, when I try to set the model it doesn't work...
我想我需要使用ng-repeatvsng-option来做一些基本的事情，比如没有选择和做data-index. 但是，当我尝试设置模型时，它不起作用......
$scope.model.RemediationCredentials = "Zoo"
Any suggestions?
有什么建议？

use the Angular Select Directive:
使用角度选择指令：
http://docs.angularjs.org/api/ng.directive:select
http://docs.angularjs.org/api/ng.directive:select
Should look something more like this:
应该看起来更像这样：
<select ng-model="model.RemediationCredentials" name="remediationCredential" id="remediationCredential" ng-options="cred.value as cred.key for cred in credentialsList">
<option value="0">---</option>
</select>
