1.基本下拉效果(lable for value in array)
其中select标签中的ng-model属性必须有,其值为选中的对象或属性值。
<div ng-controller="ngselect"> <p>usage:label for value in array</p> <p>选项,{{selected}}</p> <select ng-model="selected" ng-options="o.id for o in optData"> <option value="">-- 请选择 --</option> </select> </div> m1.controller("ngselect",['$scope',function($sc){ $sc.selected = ''; $sc.optData = [{ id: 10001, MainCategory: '男', ProductName: '水洗T恤', ProductColor: '白' },{ id: 10002, MainCategory: '女', ProductName: '圓領短袖', ProductColor: '黃' },{ id: 10003, MainCategory: '女', ProductName: '圓領短袖', ProductColor: '黃' }]; }]);
2.自定义下拉显示名称(label for value in array)
label可以根据需要拼接出不同的字符串
<div ng-controller="ngselect2"> <p>usage:label for value in array(label可以根据需求拼接出不同的字符串)</p> <p>选项,{{selected}}</p> <select ng-model="selected" ng-options="(o.ProductColor+'-'+o.ProductName) for o in optData"> <option value="">-- 请选择 --</option> </select> </div> m1.controller("ngselect2",['$scope',function($sc){ $sc.selected = ''; $sc.optData = [{ id: 10001, MainCategory: '男', ProductName: '水洗T恤', ProductColor: '白' },{ id: 10002, MainCategory: '女', ProductName: '圓領短袖', ProductColor: '黃' },{ id: 10003, MainCategory: '女', ProductName: '圓領短袖', ProductColor: '黃' }]; }]);
3.ng-options 选项分组
group by分组项
<div ng-controller="ngselect3"> <p>usage:label group by groupName for value in array</p> <p>选项,{{selected}}</p> <select ng-model="selected" ng-options="(o.ProductColor+'-'+o.ProductName) group by o.MainCategory for o in optData"> <option value="">-- 请选择 --</option> </select> </div> m1.controller("ngselect3",['$scope',function($sc){ $sc.selected = ''; $sc.optData = [{ id: 10001, MainCategory: '男', ProductName: '水洗T恤', ProductColor: '白' },{ id: 10002, MainCategory: '女', ProductName: '圓領长袖', ProductColor: '黃' },{ id: 10003, MainCategory: '女', ProductName: '圓領短袖', ProductColor: '黃' }]; }]);
4.ng-options 自定义ngModel的绑定
<div ng-controller="ngselect4"> <p>usage:select as label for value in array</p> <p>选项,{{selected}}</p> <select ng-model="selected" ng-options="o.id as o.ProductName for o in optData"> <option value="">-- 请选择 --</option> </select> </div> m1.controller("ngselect4",['$scope',function($sc){ $sc.selected = ''; $sc.optData = [{ id: 10001, MainCategory: '男', ProductName: '水洗T恤', ProductColor: '白' },{ id: 10002, MainCategory: '女', ProductName: '圓領长袖', ProductColor: '黃' },{ id: 10003, MainCategory: '女', ProductName: '圓領短袖', ProductColor: '黃' }]; }]);
