我搜索了这个问题并进行了探索并得到了解决方案,但它们并不适合我,我想在打字稿的下拉选项中显示静态数据/列表,我正在使用对象数组leaveType
。但是,当我这样做,然后得到这个错误:在Angular 2中,无法找到类型为'leaveType'的不同支持对象'[object Object]'。 NgFor只支持绑定到Iterables,比如数组
原来的例外:无法找到类型'leaveType'不同的支持对象'[object object]'。 NgFor仅支持与阵列等Iterables绑定。
请建议我在哪里做错了。
我的代码是:
团队component.ts
import { Component, OnInit, HostBinding } from '@angular/core';
import { FormGroup, FormBuilder, Validators } from '@angular/forms';
import { IMyOptions, IMyDateModel } from 'mydatepicker';
import { CONSTANT } from '../../constants/dash-constant';
import { TeamService } from '../../services/team-component.service';
import { slideInDownAnimation } from '../../animations/animations'
@Component({
selector: 'team-component',
templateUrl: `../app/modules/dashboard/dashComponents/teamComponents/team.component.html`,
animations: [slideInDownAnimation],
})
export class TeamComponent implements OnInit {
@HostBinding('@routeAnimation') routeAnimation = true;
@HostBinding('style.display') display = 'block';
@HostBinding('style.position') position = 'absolute';
constructor(private teamService: TeamService) {
}
ngOnInit() {
this.leaveType.push({ id: 0, type: 'Earned Leave' });
console.log(this.leaveType);
}
private leaveType:any=[];
public leave:any= { "employee": null, "from": null, "to": null,'leaveType':null };
}
团队component.html:
<div class="row">
<h4>Leave Type:</h4>
<div class="form-group col-md-10">
<select id="leaveType" class="form-control" name="leaveType" [(ngModel)]="leave.leaveType" required #leaveType="ngModel">
<option *ngFor="let p of leaveType" [value]="p.type">{{p.type}}</option>
</select>
<div *ngIf="leaveType.errors && leaveType.touched" class="alert alert-danger">
<div [hidden]="!leaveType.errors.required && leaveformSubmitted">Leave type is required</div>
</div>
</div>
</div>
你说得对@苏拉杰,我用leaveTypes然后它的工作。非常感谢。 –
