[Java教程]AngularJS之ng


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'    }];  }]);
