Pass ng-repeat expression to ng-click function

Question

The html template contains a list of items filtered

        <ul class="gift_info">
         <li ng-repeat="code in codes | filter:{id_id:detail.id}">{{code.discount}}</li>
        </ul>

Below this list there is a button with code like

<button type="button" ng-click="add_something(repeat_expression_needed)">Add more</button>

The goal is to feed the items from ng-repeat above to function below as a param (collection, array, whatever). Is it doable via mere template directives or some controller tricks need to be involved?

Answer 1

The code using the method @Jonathan pointed out

<ul class="gift_info">
    <li ng-repeat="code in (filteredCodes = (codes | filter: {id_id:detail.id})">{{code.discount}}</li>
</ul>

and then

<button type="button" ng-click="add_something(filteredCodes)">Add more</button>

Answer 2

You can use an expression inside of the ng-repeat to assign a variable that will hold the collection and will then be available inside the scope.
