I am trying to get option value from select box on button click but it shows undefined in console .Options value are coming from server

Here is my html code

<div class="form-group">
        <label class="control-form" for="cityid">Selct City</label>
        <select type="text" class="form-control" placeholder="City" id="acity" >
            <option value="">--Select City--</option>
            <option ng-repeat="city in cityinfo" ng-value="{{city.id}}"  ng-selected="{{city.id ==cityid}}">{{city.cityname}}</option>

Controller.js file code

Answer 1

Use ng-options instead of ng-repeat.

Like this:

Updated

<select type="text" class="form-control" placeholder="City" id="acity" ng-options="city.id as city.cityname for city in cityinfo track by city.id" ng-model="selectedCity">
    <option value="">--Select City--</option>
</select>
<button class="btn btn-info prevnext pull-right" ng-click="nextpage(selectedCity)">Next <i class="fa fa-arrow-right"></i></button>

JS:

$scope.nextpage = function(selectedCity){
    console.log(selectedCity);
}
