角度選擇模型在控制器中不更新

Question

我想在控制器中獲得$ scope.selectedBranch，但它沒有更新。如果我在HTML中使用$ scope.selectedBranch，它工作正常。

<select ng-model="selectedBranch" ng-change="onBranchChange()" ng-options="branch for branch in data.branches" 

所有

$scope.onBranchChange= function(){ 
    console.log($scope.selectedBranch) 
}; 


data = {"branches" : ["343dfds","dfdf43","sdfsd","sadser343"]} 

Answer 1

前綴$範圍與數據。 它應該像下面：

$scope.data = {"branches" : ["343dfds","dfdf43","sdfsd","sadser343"]}
