I have a template:
<div class="oss-object cp-def cp-row" ng-repeat="(key, value) in data" ng-init="viewables = getViewables(value.versions[0].objectInfo);">
<div class="cp-def">
{{value.info.name}} OssStatus: {{value.versions[0].objectInfo.status}}
, 3D-Viewables:
<select ng-change="viewableSelected(value.versions[0].urn, viewables, '3d')" ng-model="viewables.selected3d" ng-options="viewable as viewable.name for viewable in viewables['3d']">
<option value="">---Please select---</option>
</select>
, 2D-Viewables:
<select ng-change="viewableSelected(value.versions[0].urn, viewables, '2d')" ng-model="viewables.selected2d" ng-options="viewable as viewable.name for viewable in viewables['2d']">
<option value="">---Please select---</option>
</select>
</div>
</div>
And when data gets updated (the data property used in the top ng-repeat
) in my controller with a new data set, it doesn't automatically refresh the child scopes in the ng-options
. which are derived from the data set. Does anyone know how to refresh child scopes
? I have tried calling $apply
and $digest
but with no success.
If you look at the docs for ngInit
, you'll see they basically say "never use this except in nested ngRepeats
". One way to do what you want is to create a controller for each repeated item, and create a $watch
on the data that changes (or expression in this case), and set viewables
equal to that.
eg
function ViewablesCtrl($scope){
$scope.$watch($scope.getViewables, function(){$scope.viewables = $scope.getViewables($scope.value.versions[0].objectInfo);}
})
--
<div class="oss-object cp-def cp-row" ng-repeat="(key, value) in data" ng-controller="ViewablesCtrl()">
正如我在评论中所说,您可以尝试将ng-options中的viewables['3d']
替换为getViewables(value, '3d')
并让控制器返回数组。
