角度选择模型未在控制器中更新

Question

我试图在控制器中获取 $scope.selectedBranch 但它没有更新。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"

全部

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


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

Answer 1

在 $scope 前加上数据。 应该是这样的：

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