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

下面selected的值为optData的id 效果 http://sandbox.runjs.cn/show/nhi8ubrb

<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' }];}]);
