Having trouble selecting a default option in a dynamically populated select dropdown using ng-model in the dropdown

For my Angularjs application, I needed to dynamically return a select drop down with its selected option. To accomplish this, I implemented the following function:

 function getCellRendererMapping(data) {

     if (data.order == 6) {
         return function(params) {
             params.$scope.payRateRegDataOptions = data.data;
             var dynamicScopename = "data.' + params.colDef.field + data.order +'"
             $scope.dynamicScopename = data.data[0];
             // console.log("dynamic scope value" +  $scope[dynamicScopename]);
             return '<select ng-options="eachPayRate.text for eachPayRate in payRateRegDataOptions" name="payrate_s' + params.column.index + '" id="payrate_s' + params.column.index + '" ng-model="dynamicScopename"></select>';
         }
     }

 }

Although the dropdown is forming correctly and being populated with options, I am facing an issue with setting the default selection. Even though I have tried to set the default option using the code below, the ng-model, (dynamicScopename), is not being properly configured.

   $scope.dynamicScopename = data.data[0];

Answer №1

In my opinion, it would be beneficial to include the ng-selected="dynamicScopename" attribute. Hopefully this suggestion proves helpful.

return '<select ng-options="eachPayRate.text for eachPayRate in payRateRegDataOptions" name="payrate_s' + params.column.index + '" id="payrate_s' + params.column.index + '" ng-model="dynamicScopename" ng-selected="dynamicScopename"></select>'
