AngularJS: How to eliminate empty select options in ng-repeat using Angular framework

My code is utilizing ng-repeat to display options with different values and texts, while also designating a default selection. However, Angular is introducing an additional empty undefined option.

<select ng-model="newItem.financial_year_id" required style="min-width:180px;">
   <option ng-repeat="financial in account_year" value="{{financial.id}}" ng-selected="financial.status=='Active'">{{financial.financial_year}}</option>
</select>

Although the active option is correctly selected, an unwanted empty option continues to appear.

Answer №1

When using ng-model with ng-options, an empty option can be generated if the value referenced by ng-model is not present in the set of options provided.

You can refer to a comprehensive answer and example on stackoverflow by following this link

UPDATE:

Here's a demonstration:

 <select ng-model="newItem.financial_year_id" required style="min-width:180px;">
   <option ng-repeat="financial in account_year" value="{{financial.id}}" ng-selected="financial.status=='Active'">{{financial.financial_year}}</option>
</select>

In the controller:

$scope.newItem={};
$scope.account_year=[{id:1,financial_year:"2013-2014",status:"Active"},
                     {id:2,financial_year:"2014-2015",status:"Inactive"}] 
//remove empty option
$scope.newItem.financial_year_id=$scope.account_year[0].id;

Consider using ng-options instead:

<select ng-model="selectedFinancial" ng-options="c.financial_year for c in account_year"
        required style="min-width:180px;">
</select>

DEMO

Your data model could benefit from utilizing ng-options. When using <select>, ensure there is only one selected item which should be a property of $scope referring to an item in the list, eliminating the need for additional properties like "active" and "inactive" for each object.

The current model design is suitable for multiple selected items, otherwise consider using checkboxes rather than <select>

To bind with Id, you can try this approach:

<select ng-model="selectedFinancialId" ng-options="c.id as c.financial_year for c in account_year"
        required style="min-width:180px;">
</select>

Answer №3

When it comes to handling options in Angular, ng-option is a great choice. However, if you prefer using ng-repeat, make sure to follow this syntax:

$scope.newItem.financial_year_id = "";

It's important to initialize the variable at the start of the controller. Failure to do so may result in the variable being undefined, leading to an initial empty value.
