Access outer $index when ng-repeat are nested in AngularDart - dart

Question

Consider the following nested ng-repeat directives:
<tr ng-repeat="r in SomeExpr1">
<td ng-repeat="c in SomeExpr2">
<p>c index is {{$index}}, r index is {{???}}</p>
</td>
</tr>
How can I access the $index of the outer ng-repeat (i.e., the one in the parent scope that is hidden by the inner ng-repeat scope $index)?

Answer 1

As #Randal Schwartz pointed out in this post $parent does the trick.
<div ng-controller='demo-ctrl'>
<div ng-repeat="row in ctrl.matrix">
<div ng-repeat="column in row">
<span>outer: {{$parent.$index}} inner: {{$index}}</span>
</div>
</div>
</div>

Answer 2

You need ng-init from Angular.js. Sadly, that hasn't been ported yet, but it would look like this if it worked:
<script>
function Ctrl($scope) {
$scope.list = [['a', 'b'], ['c', 'd']];
}
</script>
<div ng-controller="Ctrl">
<div ng-repeat="innerList in list" ng-init="outerIndex = $index">
<div ng-repeat="value in innerList" ng-init="innerIndex = $index">
<span class="example-init">list[ {{outerIndex}} ][ {{innerIndex}} ] = {{value}};</span>
</div>
</div>
</div>
