虽然ng-model用于选择框,ng-selected也用于选项,其中某些条件是ng-selected时间不起作用.

如果我将删除ng-model而不是ng-selected正在工作,但是如果我将删除ng-model而不是我应该如何获得控制器中选择框的值.

请帮忙 !

这是我的代码......

HTML:

<select class="form-control" ng-change="accessModeSelected()">
     <option ng-selected="mode.status == '1'"  ng-repeat="mode in storageResult.accessMode" ng-value="mode.name" name="accessMode{{$index}}" id="accessMode">
           {{mode.name}}
     </option>
</select>

AngularJS:

$scope.storageResult   = {
           "storageAccount":"Enable", 
           "user": "sdcard",
           "pass": "sdcard",
           "wifiIP": "0",
           "ipAddr": "0",
           "accessMode": [
                {"name": "Local Storage","status": "0"},
                {"name":"WiFi Storage", "status": "1"},
                {"name":"Internet Storage", "status": "0"}
            ]
         }

我在父组件中有一个要检测发出的事件的地方。

child.component.ts

@Component({
    selector: 'child-component',
    templateUrl: './child.component.html',
    styleUrls: ['./child.component.scss']
})   
export class ChildComponent implements OnInit { 

    @Input() public state: String = 'CLOSED';

    @Output() public stateChanged: EventEmitter<String> = new EventEmitter<String>();

    this.stateChanged.emit(this.state);

}

parent.component.html

<router-outlet (stateChanged)="onStateChange($event)"><router-outlet>

parent.component.ts

onStateChange(event){
    console.log(event);
}

这对我不起作用！

编译后的HTML代码如下所示：

<router-outlet></router-outlet>
<child-component>
    // all child component code
<child-component>

有什么方法可以推(stateChanged)="onStateChange($event)"入<child-component>元素吗？

有人可以帮忙吗？
