我想在窗體中使用Angular FormGroup(我正在使用Angular 4)將下拉控件的默認值設置爲下拉控件。下拉與給定列表填充好,但默認值不set.Also它沒有顯示的代碼之後的任何錯誤是我使用的代碼 -在Angular Formgroup中初始化下拉列表
HTML代碼
<div class="col-xs-2">
<label class="control-label" for="Country">Country</label>
<select formControlName="CountryID" [(ngModel)]="CountryID" class="form-control">
<option *ngFor="let country of Countries" [ngValue]="country.CountryID">{{country.CountryName}}</option>
</select>
</div>
打字稿代碼
ngOnInit() {
this.Countries = [
{ "CountryID": 0, "CountryName": "Select Country" },
{ "CountryID": 1, "CountryName": "Country 1" },
{ "CountryID": 2, "CountryName": "Country 2" },
{ "CountryID": 3, "CountryName": "Country 3" },
{ "CountryID": 4, "CountryName": "Country 4" },
{ "CountryID": 5, "CountryName": "Country 5" }
];
this.inputProcessingForm = this._domBuilder.group({
CandidateBuilderAppId: [''],
FirstName: ['Amit'],
MiddleInitial: '',
LastName: '',
Gender: 'S',
DateOfBirth: new Date(),
SocialSecurityNumber: 0,
PersonalEmail: '[email protected]',
CorpEmail: '',
HomePhone: '',
WorkPhone: '',
WorkCellPhone: '',
WorkFax: '',
WorkExtension: '',
RemoteFax: '',
Address1: '',
Address2: '',
CountryID: 0,
State: 0,
City: 0,
ZipCode: 0
});
}
請建議如果我做錯了什麼。任何幫助,將不勝感激。
謝謝阿邁勒,我這樣做,它的工作 –
