选择子对象
请选择城市

动态类别列表显示

        <div class="label_EventDetail" align="left">Category</div>
            <select class="ion-input-select" ng-options="category.name for category in categorys" ng-model="selectedcategory" ng-change="callFunction(selectedcategory)">
                <option value="">Select Category</option>
            </select>
        </div>
//调用方法是

    $scope.callFunction = function(data) {
        console.log(data);
      //you selected any data from list show in console.
    }
当我从列表中选择任何ng更改事件时,调用上述代码

ng-change="callFunction(selectedcategory)"
并且callFunction不是必需的(取决于使用情况)

您可以从selectedcategory变量中获取所选数据

ng-change="callFunction(selectedcategory)"
