我正在使用angular 6应用程序并使用动态表单。
app.component.html:
<form (ngSubmit)="onSubmit()" [formGroup]="form">
<div formArrayName="multiDynamic">
<!-- row -->
<div *ngFor="let record of form.controls.multiDynamic.controls; let i=index">
<div class="row" [formGroupName]="i">
<div class="col-md-6" *ngFor="let question of model.questions">
<div [ngSwitch]="question.controlType">
<div class="form-group form-black label-floating">
<label class="control-label">{{question.text | titlecase}} </label>
<div *ngSwitchCase="'textbox'"><input type="text" class="form-control" [formControlName]="question.key"></div>
</div>
</div>
</div>
</div>
</div>
</div>
<button type="submit> Submit </button>
</form>
app.component.ts: 从'@ angular / core'导入{Component,OnInit,Input}; 从'@ angular / forms'导入{FormBuilder,FormGroup,Validators,FormControl,FormArray};
export class AppComponent implements OnInit {
@Input() model: any;
form: FormGroup;
ngOnInit() {
this.sharedService.getData().subscribe(data => {
this.items = data;
console.log(this.items);
});
this.form = this.fb.group({
multiDynamic: this.fb.array([
this.model.toGroup()
])
});
}
}
console.log(model.questions)给出以下内容(扩展数组)
0:Textbox {controlType: "textbox", key: "url-links", text: "url-links"}
1:Textbox {controlType: "textbox", key: "//input[@id='rcmloginuser']", text: "//input[@id='rcmloginuser']"}
2:Textbox {controlType: "textbox", key: "//input[@id='rcmloginpwd']", text: "//input[@id='rcmloginpwd']"}
3:Textbox {controlType: "textbox", key: "//input[@id='rcmloginsubmit'] ", text: "//input[@id='rcmloginsubmit'] "}
我正在使用上面的html和ts文件,如果我给出这一行,
<input id="i" type="text" class="form-control" [formControlName]="question.text">
我遇到了错误, 无法找到路径为“ multiDynamic-> 0->网址链接”的控件
在标签中,
<label class="control-label"> {{question.text | titlecase}} </label>
正在显示文本值,但是如果我在输入框中输入formControlName,那么我将收到此错误。
我正在使用angular的动态形式。
this.model.toGroup()
具有以下内容,
export class DynamicFormMultiModel {
questions = [];
multiDataResponse: any = [];
form: FormGroup;
toGroup() {
const group: any = {};
this.questions.forEach((question) => {
group[question.key] = new FormControl('');
});
return new FormGroup(group);
}
patchData() {
const arrayGroup: any = {};
const dataRes: any = [];
const resObj: any = {};
// this.multiDataResponse.forEach((element, index) => {
// this.questions.forEach((question, inx) => {
// arrayGroup[question.key] = new FormControl(element[question.key]);
// });
// });
resObj['data'] = this.multiDataResponse;
// return new FormGroup(arrayGroup);
return resObj;
}
}
由于我有嵌套代码,因此无法发布整个代码,但是我正在获取数据及其在标签中的显示,但是输入标签抛出错误。 (两者都包含相同的值question.text
)。
随附该场景的屏幕截图。
请帮助我修复卡在其中的时间过长。.
