After dynamically adding a Select Box with empty options to the DOM, what is the best way to populate it with options (ng-options)? I am facing a situation where users can add multiple select boxes to the DOM during runtime and then input values into these dynamically added select boxes.
I would greatly appreciate any assistance regarding this matter. Thank you very much.
Utilizing the ng-options attribute within a select element can assist in dynamically generating options. By keeping track of your dynamic options in the controller, the select element's options will automatically refresh when the data model is updated.
See It In Action
<div ng-controller="myCtrl">
<select ng-model="selected" ng-options="o.label for o in options">
<option value="">-------</option> <!--not selected option-->
</select>
<button ng-click="addOption('option'+(options.length+1))">Add</button>
</div>
Controlling the Functionality
angular.module('app',[])
.controller("myCtrl",function($scope){
$scope.options = [{label:"option1",value:"1"},{label:"option2",value:"2"},{label:"option3",value:"3"}];
$scope.addOption = function(text){
$scope.options.push({label:text,value:text});
}
});
Take a look at this demo on jsFiddle.
We hope this solution proves to be beneficial for your needs.
