ionic2 + Angular2 选择列表
ionic2 + Angular2 selection of list
http://ionicframework.com/docs/v2/components/#select
我正在尝试显示 select 选项并捕获 select 离子。我试过从方法、onChanges 甚至在单击时内联,但没有任何效果。
<ion-list>
<ion-item>
<ion-label>List </ion-label>
<ion-select [(ngModel)]="selected" multiple="true" cancelText="Cancel" okText="Okay!">
<ion-option *ngFor="#row of list;" value="{{row.id}}" (click)="checkSelected(row.id)" checked="{{ gq.isSelected(row.id) }}">{{ row.english_name }}</ion-option>
</ion-select>
</ion-item>
</ion-list>
设置页面class
export class SettingPage implements OnChanges{
selected;
list = [];
constructor(private nav:NavController, public gq: gq)
{
this.gq
.list()
.subscribe(data => this.list.push(data));
}
stpSelect() {
console.log('STP selected');
console.log(this.selected);
}
ngOnChanges(changes) {
console.log(changes);
}
checkSelected (data)
{
console.log('test');
console.log(data);
}
}
我只想在函数发生变化时从函数中捕获 selected 模型值。
由于 ion-select 组件利用了 ngModel,您可以尝试监听 ngModelChange 事件:
<ion-select [(ngModel)]="selected" multiple="true" cancelText="Cancel" okText="Okay!" (ngModelChange)="doSomething()">
(...)
</ion-select>
