我有一个选择
<select name='shape_id' ngModel (change)='changeShape($event.target.value)'>
<option *ngFor="let shape of shapes" [ngValue]="shape.id">{{shape.name}}</option>
</select>
这是数据.
shapes = [
{id:'1',name:'Angle'},{id:'2',name:'Bar'},];
我无法获得价值.
changeShape(shape){
console.log(shape);
}
这输出“0：1”,但我想要值1.
以下是检查器中的选项.
<option value="0: 1" ng-reflect-ng-value="1">Angle</option>
我如何获得id值1？
解决方法
将[ngValue]更改为[value]
<select name="shape_id" (change)="changeShape($event.target)">
<option *ngFor="let shape of shapes" [value]="shape.id">
{{shape.name}}
</option>
</select>
并塑造形状.价值.
changeShape(shape){
console.log(shape.value);
}
