Question

当我点击选择值列表时，我正在尝试相应地更改选择内的选定值。

我的第一个想法是尝试将这两个模型绑定在一起，但它并没有像我预期的那样工作。

＆＃13;

(function(angular) {
  'use strict';
  angular.module('staticSelect', [])
    .controller('ExampleController', ['$scope', function($scope) {
      $scope.data = {
        options: [
          1, 2, 3, 4, 5, 6, 7
        ]
      };
      $scope.selectOption = function(option) {
        // To check that I get the correct value
        alert(option);
        // I want whenever I click on a value, it will toggle the select option box sync with that value
        $scope.option1 = option;
      }

    }]);
})(window.angular);

Answer 1

你可以试试这个

<select ng-options="c.Id as c.Name for c in data" ng-model="option1">

所以在option1中，您将获得选择项目的 ID 和控制器

angular.module('staticSelect', [])
.controller('ExampleController', ['$scope', function($scope) {
  $scope.option1 = 1;
  $scope.data = [{"Id":1,"Name":"Theme1"},
                 {"Id":2,"Name":"Theme2"},
                 {"Id":3,"Name":"Theme3"}];
}]

Answer 2

使用

修改select语句

 <select name="" id="" ng-model="option1">
  <option value="option" ng-repeat="option in data.options" ng-selected="option1 == option">{{option}}</option>
</select>

希望这会对你有所帮助。
