我试图创建一个动态下拉列表，但它显示未定义，这是我的代码

Answer 1

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>

像这样的

和$ scope变量

$scope.categorys = [{
            "id": 1,
            "name": "A",
            "select": true
        }, {
            "id": 2,
            "name": "B",
            "select": true
        }, {
            "id": 3,
            "name": "C",
            "select": true
        }, {
            "id": 4,
            "name": "D",
            "select": true
        }, {
            "id": 5,
            "name": "E",
            "select": true
        }, {
            "id": 6,
            "name": "F",
            "select": true
        }, {
            "id": 0,
            "name": "G",
            "select": true
        }];

//并且调用方法是

    $scope.callFunction = function(data) {
        console.log(data);
      //you selected any data from list show in console.
    }

上面的代码当我从列表中选择任何一个ng-change事件被称为

ng-change="callFunction(selectedcategory)"

并且callFunction不是必需的（它取决于使用）。

您可以从 selectedcategory 变量中选择数据。

角度js或离子的动态下拉
