Get value from ng-repeat outside of ng-repeat - angularjs

Question

I got a header bar outside of ng-repeat:
<ion-header-bar class="headerView" ng-show="!hideAll">
<button id="shareImage" class="button button-icon icon ion-share" style="color:#fff" ng-click="shareImageTo({{originalImageSource}})"></button>
<button class="button button-outline button-light close-btn" ng-click="closeModal()">{{::actionLabel}}</button>
</ion-header-bar>
And a slidebox where images are shown:
<ion-slide ng-repeat="single in slides track by $index">
<div class="item item-image gallery-slide-view">
<img ng-src="{{single.original}}">
<input type="text" ng-model="originalImageSource" value="{{single.original}}">
</div>
</ion-slide>
{{single.original}} is an URL to an image. But this URL is not placed in the input field. It is shown when I´m deleting this ng-model statement.
If a user clicks the button #shareImage the ShareImageTo(URL) function is executed. But with an undefined value for {{originalImageSource}}.
Any thoughts on how i could pass the URL in {{single.original}} to this ShareImageTo() function?

Answer 1

With $ionicSlideBoxDelegate you can get the current slide index via currentIndex(). That enables you to get the URL by $scope.slides[$ionicSlideBoxDelegate.currentIndex()].original in your ShareImageTo()-method like that:
$scope.ShareImageTo = function() {
var URL = $scope.slides[$ionicSlideBoxDelegate.currentIndex()].original;
//your logic
};
Another approach would be to use ion-slide-box's directive on-slide-changed.
Template:
<ion-slide-box on-slide-changed="slideHasChanged($index)">
...
</ion-slide-box>
Controller:
$scope.slideHasChanged = function(index) {
$scope.originalImageSource = $scope.slides[index].original;
//.. some more logic
}

Just create a div that wrap around both your navbar and your slidebox, and place your ng-repeat in that div :)
