angularjs - Empty Option field in Select tag - Angualr js -


i getting empty option field in select tag.

my code shown below:

openselectboxmodel="47" openselectlist=[{id:""47",name:"text"}]; valuekey="id"; titlekey="name";  <select id="reportopenselectboxsingle" size="6" ng-style='selectstyle' class="openselectbox" ng-model="openselectboxmodel" ng-change="changefn()" > <option ng-selected="openselectboxmodel===item[valuekey]" ng-repeat="item in openselectlist" id="" ng-value="{{item[valuekey]}}" ng-title="{{item[titlekey]}}" ng-bind="item[titlekey]"></option> </select>

please me solve problem.

you should not use ng-selected ng-model.

the thing bind selected item ng-model before displaying it.

//also, instead of ng-repeat, should use ng-option
far performance regarded : ng-options not create child scopes every iteration. when angular performs digest, ng-repeat slow it. if have list hundreds of elements, feel difference.

<select id="reportopenselectboxsingle"          size="6"          ng-style='selectstyle'          class="openselectbox"          ng-model="openselectboxmodel"          ng-change="changefn()" >      <option ng-repeat="item in openselectlist"               value="{{item[valuekey]}}"               title="{{item[titlekey]}}"               ng-bind="item[titlekey]">      </option> </select>

furthermore, need declare variables inside controller :

$scope.openselectboxmodel="47"; $scope.openselectlist=[{id:"47",name:"text"}]; $scope.valuekey="id"; $scope.titlekey="name";
