Question

默认情况下，单选按钮不会显示为已选中。我试图默认选中我的第一个选项。但它没有用......任何想法或建议？

<div Class ="form-group">
    <label>Select your Email Hierarchy</label>

    <div class="radio" ng-switch="deliveryMethod">
    <div ng-switch-when="email">
    <label>
    <input type="radio" id="delivery-email" name="delivery-email"
        ng-model="generated.delivery" ng-change="checkValidGenerate()"
        class="check" value="EE/ER" checked="checked"/>
     EE/ER
     </label><br/>
<!-- some code--other option listed -->

Answer 1

嗯，起初没有必要使用checked。如果您将value归因于ngModel，它应该有效，否则它不会起作用：

$scope.generated.delivery = 'EE/ER';

请参阅以下示例：

＆＃13;

(function() {
  'use strict';

  angular
    .module('app', [])
    .controller('MainCtrl', MainCtrl);

  MainCtrl.$inject = ['$scope'];

  function MainCtrl($scope) {
    $scope.deliveryMethod = 'email';
    $scope.generated = {};
    $scope.generated.delivery = 'EE/ER';
  }
})();

<!doctype html>
<html ng-app="app">

<head>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.7/angular.min.js"></script>
  <script src="script.js"></script>
</head>

<body ng-controller="MainCtrl">
  <div Class="form-group">
    <label>Select your Email Hierarchy</label>
    <div class="radio" ng-switch="deliveryMethod">
      <div ng-switch-when="email">
        <label>
          <input type="radio" id="delivery-email" name="delivery-email" ng-model="generated.delivery" ng-change="checkValidGenerate()" value="EE/ER"> EE/ER
        </label>
        <br/>
      </div>
    </div>
  </div>
</body>

</html>
