Suppose, I have :
$scope.head1="abc";
$scope.head2="bfc";
...
...
$scope.head12="bfc";
and, I do this :
<div ng-repeat="count in [3,4,5,6,7,8,9,10,11,12]" class="padding-top-10">
<span>{{head + count}}</span>
</div>
I want to get the values of head1, head2, head3.. head12 in the div. How to do that ?
Any reason you're not doing this?
$scope.head = ["abc", "bfc", ..., "bfc"];
View:
<div ng-repeat="count in [3,4,5,6,7,8,9,10,11,12]" class="padding-top-10">
<span>{{ head[count - 1] }}</span>
</div>
If that's not an option, you can define this method:
$scope.getHead = function (num) {
return $scope["head" + num];
};
And then:
<div ng-repeat="count in [3,4,5,6,7,8,9,10,11,12]" class="padding-top-10">
<span>{{ getHead(count) }}</span>
</div>
You can do this
<div ng-repeat="count in [1,2,3,4,5,6,7,8,9]" class="padding-top-10">
<span>{{$parent['head'+count]}}</span>
</div>
</body>
Like this you do not need an extra scope function to get the values from your scope variables. $parent is necessary because your ng-repeat creates its own scope.
angular docs--> ngRepeat - directive in module ng The ngRepeat directive instantiates a template once per item from a collection. Each template instance gets its own scope,
Use property accessor bracket notation with the this context keyword:
<div ng-repeat="count in [3,4,5,6,7,8,9,10,11,12]" class="padding-top-10">
<span>{{this["head"+count]}}</span>
</div>
With Angular Expressions the this keyword evaluates to the $scope of the expression.
Be aware that the ng-repeat directive creates child scopes and that this expression finds the value by prototypical inheritance. This can cause problems when using this in ng-model directives. (This issue with primitives can be easily avoided by following the "best practice" of always have a '.' in your ng-models)

head1head2etc and simply display the values in the array?
