I have the following loop in which I'm trying to increment several fields based on the array index each time through the loop.
<div class="individualwrapper" ng-repeat="n in [] | range:4">
<div class="iconimage"></div>
<div class="icontext">
<p>Imagine that you are in a health care facility.</p>
<p>Exactly what do you think this symbol means?</p>
<textarea type="text" name="interpretation_1" ng-model="interpretation_1" ng-required="true"></textarea>
<p>What action you would take in response to this symbol?</p>
<textarea type="text" name="action_1" ng-model="action_1" ng-required="true"></textarea>
</div>
</div>
I'd like to do something similar to this"
ng-model="interpretation_{{$index + 1}}"
Angular is not rendering that value though? What would be the best way to go about adding this kind of logic in the mg-model field?
It becomes an invalid expression with the usage of interpolation with ng-model expression. You need to provide a property name there. Instead you can use an object and use bracket notation.
i.e in your controller:
$scope.interpretation = {};
and in your view use it as:
ng-model="interpretation[$index + 1]"
Demo
angular.module('app', []).controller('ctrl', function($scope) {
$scope.interpretation = {};
$scope.actions = {};
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.8/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
{{interpretation}} {{actions}}
<div class="individualwrapper" ng-repeat="n in [1,2,3,4]">
<div class="iconimage">
</div>
<div class="icontext">
<p>Imagine that you are in a health care facility.</p>
<p>Exactly what do you think this symbol means?</p>
<textarea type="text" ng-attr-name="interpretation{{$index + 1}}" ng-model="interpretation[$index+1]" ng-required="true"></textarea>
<p>What action you would take in response to this symbol?</p>
<textarea type="text" name="action{{$index + 1}}" ng-model="actions[$index+1]" ng-required="true"></textarea>
</div>
</div>
</div>
