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'
}];
}]);
