AngularJS populate textbox from array - arrays

Question

I am facing a problem with AngularJS. I have made an application where a user can
select a value from a dropdown list. If the user presses the "add" button, then an array is created that holds all his selections. I want to populate a textbox with all these selections. I have tried ng-repeat but it creates multiple textbox with each array value. This is what I've made so far:
Controller
$scope.multiCompare= [];
// Create the function to push the data into the "multiCompare" array
$scope.newCompare = function () {
$scope.multiCompare.push($scope.compareDate);
$scope.multiComparedate = '';
};
HTML
<div class="form-group">
<label for="installation_year" class="col-sm-2 control-label">Period</label>
<div class="col-sm-4">
<select class="form-control" ng-model="compareDate" ng-options="res for res in compareDates " ng-disabled="disableFormInput()" ></select>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default" ng-click="newCompare()">Add</button>
</div>
</div>
<div class="form-group">
<label for="from_date" class="col-sm-2 control-label">Compare</label>
<div class="col-sm-4">
<div ng-repeat="num in multiCompare" track by $index>
<input class="form-control" type="text" ng-model="$parent.multiCompare[$index]">
<div> {{num}}</div>
</div>
</div>
The first image shows the result I'm getting when adding 2013 and 2014 and the second shows what I would like it to return.
Can someone help me through this?
Thanks in advance..

Answer 1

For rendering your Compare field input, you can take use of ngList directive. That will bind your comma(,) separated output directly to the input element.
Change
<label for="from_date" class="col-sm-2 control-label">Compare</label>
<div class="col-sm-4">
<div ng-repeat="num in multiCompare" track by $index>
<input class="form-control" type="text" ng-model="$parent.multiCompare[$index]">
<div> {{num}}</div>
</div>
</div>
TO
<label for="from_date" class="col-sm-2 control-label">Compare</label>
<div class="col-sm-4">
<input class="form-control" type="text" ng-model="multiCompare" ng-list/>
</div>
This could help you, Thanks.

I have managed to do what I wanted. I changed my html code to this:
<div class="form-group">
<label for="from_date" class="col-sm-2 control-label">Compare</label>
<div class="col-sm-4">
<div data-ng-repeat="num in multiCompare" track by $index>
<input class="form-control" type="text" ng-model="multiCompare" ng-list {{num}} ng-show="$last" />
</div>
</div>
</div>
And it worked!
Your ng-list suggestion was really helpful! Thank you very much!
