Question

这是我的下拉列表

 <select class="form-control" data-ng-options="obj.text for obj in options track by obj.value" data-ng-model="submission.issue" ng-init="submission.issue = options[0]" required></select>

这是填充我的下拉菜单，但是当我查看“submission.issue”的值时，我没有看到select中的选项项的值如预期，而是像

"Query {"text":"Select your query","value":""} "

默认情况下，我只想将submission.issue默认项目作为列表中第一个值为“”的项目。

以下是我填充列表的方法

$scope.options = [
          { text: $scope.select_default, value: "" },
          { text: $scope.select_issue_1, value: $scope.select_issue_1 },
          { text: $scope.select_issue_2, value: $scope.select_issue_2 },
          { text: $scope.select_issue_3, value: $scope.select_issue_3 },
          { text: $scope.select_issue_4, value: $scope.select_issue_4 },
          { text: $scope.select_issue_5, value: $scope.select_issue_5 }
        ];

Answer 1

将ng-options表达式更改为如下所示：

"obj.value as obj.text for obj in options track by obj.value"

$ scope.submission.issue应该等于下拉列表中所选项目的值。

Angular Dropdown所选项目未获得正确的值
