我有一个md-select设置如下:
<md-select placeholder="Category" ng-model="current.Category" flex > <md-option ng-repeat="item in categories" ng-value="{{item}}">{{item.Name}}</md-option> </md-select>
@ scope.categories值是
[ { "Name":"Commercial & Industrial","ParentId":null,"Categories":[ { "Name":"Deceptive Marketing","ParentId":19,"Categories":[ ],"Id":24,"ModifiedDate":"2015-08-06T07:49:53.0489545","CreatedDate":"2015-08-06T15:49:51.707" },{ "Name":"Aggressive Agents","Id":25,"ModifiedDate":"2015-08-06T07:50:10.0026497","CreatedDate":"2015-08-06T15:50:08.63" } ],"Id":19,"ModifiedDate":"08/06/2015 @ 7:49AM","CreatedDate":"08/06/2015 @ 3:49PM" },{ "Name":"Competitive Supply","Categories":[ { "Name":"Security Deposit","ParentId":20,"Id":21,"ModifiedDate":"2015-08-06T07:49:30.3966895","CreatedDate":"2015-08-06T15:49:25.8" },{ "Name":"Meter","Id":22,"ModifiedDate":"2015-08-06T07:49:34.6571155","CreatedDate":"2015-08-06T15:49:33.3" },{ "Name":"Bill","Id":23,"ModifiedDate":"2015-08-06T07:49:41.7268224","CreatedDate":"2015-08-06T15:49:40.357" } ],"Id":20,"CreatedDate":"08/06/2015 @ 3:49PM" } ]
md-select工作正常.但是我无法想像的是如何设置选择值.当我尝试将模型current.Category设置为$scope.categories中的一个值时,它不会设置.
文档不明确,但您应该使用ng选择.我创造了一个
codepen来说明,但基本上是:
<md-option ng-repeat="(index,item) in categories" ng-value="{{item}}" ng-selected="index == 1"> {{item.Name}} </md-option>
这将选择第二个类别(您的类别数组中的索引1).
