Question

我正面临着Angular和Ionic的问题。我有以下代码段：

控制器：

  <head runat="server">
        <title></title>
         <script type="text/javascript">
             function IsValidUrl()
             {
                 var emailbox = document.getElementById('<%=TextBox4.Text %>');<!--textbox4 is used to receive the email entered by the user-->
                 var email = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
                 if (textbox.value.length > 0)<!--the email field should be non empty-->
                 {
                     if (email.test(emailbox.value))
                     {
                         return true;
                     }
                     else
                     {

                         alert("Please enter valid Email");<!--incase of an invalid email-->
                         return false;
                     }

                 }
                 else
                 {
                     alert("please enter text");
                     return false;
                 }


             }
            </script>
    </head>
    <body>
        <form id="form1" runat="server">
    <asp:Button ID="Button1" runat="server" style="margin-left: 340px" Text="Submit" Width="96px" OnClick="Button1_Click1" OnClientClick="javascript:IsValidUrl();"/>
      </form>
    </body>``

HTML：

app.controller('CatagoryItemsContoller', ['$scope', function($scope) {
  'use strict';

  $scope.stringArr = ["Yes","No","MayBe"];
  $scope.selectedItem = "Yes";

}]);

我总是得到一个空的选择框。这里发生了什么？

注意：我通过角度路由登陆此页面。

Answer 1

ng-model 而非 ng-modal

更改

发件人：

<select ng-modal="selectedItem" ng-options="o as o for o in stringArr"></select>

要

<select ng-model="selectedItem" ng-options="o as o for o in stringArr"></select>

工作Plunker

具有离子角度ng选项的空选择框
