<div ng-controller="ngselect">
  <p>usage:label for value in array</p>
  <p>選項(xiàng)，{{selected}}</p>
  <select ng-model="selected" ng-options="o.id for o in optData">
    <option value="">-- 請(qǐng)選擇 --</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(lǐng)短袖',
    ProductColor: '黃'
  },{
    id: 10003,
    MainCategory: '女',
    ProductName: '圓領(lǐng)短袖',
    ProductColor: '黃'
  }];
}]);

2.自定義下拉顯示名稱(chēng)(label for value in array)

label可以根據(jù)需要拼接出不同的字符串

<div ng-controller="ngselect2">
  <p>usage:label for value in array(label可以根據(jù)需求拼接出不同的字符串)</p>
  <p>選項(xiàng)，{{selected}}</p>
  <select ng-model="selected" ng-options="(o.ProductColor+'-'+o.ProductName) for o in optData">
    <option value="">-- 請(qǐng)選擇 --</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(lǐng)短袖',
    ProductColor: '黃'
  },{
    id: 10003,
    MainCategory: '女',
    ProductName: '圓領(lǐng)短袖',
    ProductColor: '黃'
  }];
}]);

3.ng-options 選項(xiàng)分組

group by分組項(xiàng)

<div ng-controller="ngselect3">
  <p>usage:label group by groupName for value in array</p>
  <p>選項(xiàng)，{{selected}}</p>
  <select ng-model="selected" ng-options="(o.ProductColor+'-'+o.ProductName) group by o.MainCategory for o in optData">
    <option value="">-- 請(qǐng)選擇 --</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(lǐng)長(zhǎng)袖',
    ProductColor: '黃'
  },{
    id: 10003,
    MainCategory: '女',
    ProductName: '圓領(lǐng)短袖',
    ProductColor: '黃'
  }];
}]);

4.ng-options 自定義ngModel的綁定

下面selected的值為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>選項(xiàng)，{{selected}}</p>
  <select ng-model="selected" ng-options="o.id as o.ProductName for o in optData">
    <option value="">-- 請(qǐng)選擇 --</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(lǐng)長(zhǎng)袖',
    ProductColor: '黃'
  },{
    id: 10003,
    MainCategory: '女',
    ProductName: '圓領(lǐng)短袖',
    ProductColor: '黃'
  }];
}]);
