AngularJS学习笔记之ng-options指令
1.基本下拉效果(lableforvalueinarray)
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。
<divng-controller="ngselect">
<p>usage:labelforvalueinarray</p>
<p>选项，{{selected}}</p>
<selectng-model="selected"ng-options="o.idforoinoptData">
<optionvalue="">--请选择--</option>
</select>
</div>
m1.controller("ngselect",['$scope',function($sc){
$sc.selected='';
$sc.optData=[{
id:10001,
MainCategory:'男',
ProductName:'水洗T恤',
ProductColor:'白'
},{
id:10002,
MainCategory:'女',
ProductName:'圓領短袖',
ProductColor:'黃'
},{
id:10003,
MainCategory:'女',
ProductName:'圓領短袖',
ProductColor:'黃'
}];
}]);
2.自定义下拉显示名称(labelforvalueinarray)
label可以根据需要拼接出不同的字符串
<divng-controller="ngselect2">
<p>usage:labelforvalueinarray(label可以根据需求拼接出不同的字符串)</p>
<p>选项，{{selected}}</p>
<selectng-model="selected"ng-options="(o.ProductColor+'-'+o.ProductName)foroinoptData">
<optionvalue="">--请选择--</option>
</select>
</div>
m1.controller("ngselect2",['$scope',function($sc){
$sc.selected='';
$sc.optData=[{
id:10001,
MainCategory:'男',
ProductName:'水洗T恤',
ProductColor:'白'
},{
id:10002,
MainCategory:'女',
ProductName:'圓領短袖',
ProductColor:'黃'
},{
id:10003,
MainCategory:'女',
ProductName:'圓領短袖',
ProductColor:'黃'
}];
}]);
3.ng-options选项分组
groupby分组项
<divng-controller="ngselect3">
<p>usage:labelgroupbygroupNameforvalueinarray</p>
<p>选项，{{selected}}</p>
<selectng-model="selected"ng-options="(o.ProductColor+'-'+o.ProductName)groupbyo.MainCategoryforoinoptData">
<optionvalue="">--请选择--</option>
</select>
</div>
m1.controller("ngselect3",['$scope',function($sc){
$sc.selected='';
$sc.optData=[{
id:10001,
MainCategory:'男',
ProductName:'水洗T恤',
ProductColor:'白'
},{
id:10002,
MainCategory:'女',
ProductName:'圓領长袖',
ProductColor:'黃'
},{
id:10003,
MainCategory:'女',
ProductName:'圓領短袖',
ProductColor:'黃'
}];
}]);
4.ng-options自定义ngModel的绑定
下面selected的值为optData的id效果http://sandbox.runjs.cn/show/nhi8ubrb
<divng-controller="ngselect4">
<p>usage:selectaslabelforvalueinarray</p>
<p>选项，{{selected}}</p>
<selectng-model="selected"ng-options="o.idaso.ProductNameforoinoptData">
<optionvalue="">--请选择--</option>
</select>
</div>
m1.controller("ngselect4",['$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'
}];
}]);
