ng-select只给出字符串，但是我想要一个整数

问题描述

这是我的有角html文件代码.在我的mongo数据库中，将 frequencyType 添加为 frequencyType ="1" ，但是我要 frequencyType = NumberInt(1);

This is my angular html file code. In my mongo database frequencyType added as frequencyType = "1", but I want frequencyType = NumberInt(1);

<div class="span4">
  <select class="span12 combobox" ng-model="frequencyType" required>
    <option value="1">Daily</option>
    <option value="2">Weekly</option>
    <option value="3">Monthly</option>
    <option value="4">Yearly</option>
  </select>
</div>

我进入数据库 frequencyType ="1" ，但是我想要 frequencyType = NumberInt(1).

I get in my database frequencyType = "1" but I want frequencyType = NumberInt(1).

推荐答案

我建议您尝试使用 indexOf .

JS

function MyCtrl($scope) {
    $scope.values = ["Daily","Weekly","Monthly","Yearly"];
    $scope.selectedItem = 0;
}

HTML

<div ng-app ng-controller="MyCtrl">
    <select ng-model="selectedItem" ng-options="values.indexOf(selectedItem) as selectedItem for selectedItem in values"></select>
    selectedItem: {{selectedItem}}
</div>

演示

因此发送到mongoDB $ scope.selectedItem 值

So send to mongoDB $scope.selectedItem value
