我正在研究MEAN Stack Web应用程序。我试图在我的一个模型中使用2D数组。这是特定字段的架构：
alerts: [{ name: String, time: Number}]
现在我正在尝试在我的UI应用程序中访问它。这是我访问数据的方法。
控制器中的代码：
$scope.getalerts = function(){
console.log("Getting Alerts Tasks...!");
for (var i = 0; i < $scope.task.alerts.length; i++) {
if ($scope.task.alerts[i].name == "NewUserAssigned") {
$scope.task.NewUserAssigned = true;
$scope.task.NewUserAssignedtime = $scope.task.alerts[i].time;
}
else if ($scope.task.alerts[i].name == "EditedDeleted") {
$scope.task.EditedDeleted = true;
$scope.task.EditedDeletedtime = $scope.task.alerts[i].time;
}
}
视图中的代码：
<uib-tab index="4" heading="Alerts" class="nav nav-tabs">
<div id="task_alerts" class="tab-pane">
<div class="alert_block">
<div class="task_checkbox">
<input type="checkbox" class="checkbox-custom" id="assign_task_new_user" ng-model="task.NewUserAssigned" ng-checked="task.NewUserAssigned == true" alerts-block>
<label for="assign_task_new_user" class="checkbox-custom-label">When a New User Assigned</label>
</div>
<div class="alert_reminder col-lg-5" ng-if="task.NewUserAssigned == true">
<select class="alert_reminder_dd" ng-model="task.NewUserAssignedtime" >
<option value="1">1 Day Prior</option>
<option value="2">2 Day Prior</option>
<option value="3">3 Day Prior</option>
<option value="4">4 Day Prior</option>
</select>
<div class="dd_caret"></div>
</div>
</div>
<div class="alert_block">
<div class="task_checkbox">
<input type="checkbox" class="checkbox-custom" id="edit_delete_task" ng-model="task.EditedDeleted" ng-checked="task.EditedDeleted == true" alerts-block>
<label for="edit_delete_task" class="checkbox-custom-label">Task is Edited / Deleted</label>
</div>
<div class="alert_reminder col-lg-5" ng-if="task.EditedDeleted == true">
<select class="alert_reminder_dd" ng-model="task.EditedDeletedtime">
<option value="1">1 Day Prior</option>
<option value="2">2 Day Prior</option>
<option value="3">3 Day Prior</option>
<option value="4">4 Day Prior</option>
</select>
<div class="dd_caret"></div>
</div>
</div>
</div>
</uib-tab>
如果我调试它，它会正确保存数据。但是当它从数据库访问数据时，它做的是它正确地检查选项但不更新时间模型中的值。第二件事是它没有在控制台上显示数组值（在从数据库获取值之后）。
