这一直在推动我。我几乎使用了ngx-bootstrap手册中的示例:https://valor-software.com/ngx-bootstrap/#/buttons#radio-reactiveforms并且它不起作用。这是我的模板和组件:
模板:
<pre class="card card-block card-header">{{ myForm.value | json }}</pre>
<form [formGroup]="myForm" class="form-inline">
<div class="form-group">
<div class="btn-group" btnRadioGroup formControlName="radio">
<label btnRadio="A" class="btn btn-primary">A</label>
<label btnRadio="B" class="btn btn-primary">B</label>
<label btnRadio="C" class="btn btn-primary">C</label>
</div>
</div>
</form>
组件:
import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup } from '@angular/forms';
@Component({
selector: 'demo-buttons-radio-reactiveforms',
templateUrl: './keyed-payment.component.html',
styleUrls: ['./keyed-payment.component.scss']
})
export class KeyedPaymentComponent implements OnInit {
myForm: FormGroup;
constructor(private formBuilder: FormBuilder) {}
ngOnInit() {
this.myForm = this.formBuilder.group({
radio: 'C'
});
}
}
此外,我还在app.module.ts中添加了以下内容:
import { FormsModule } from '@angular/forms';
import { ReactiveFormsModule } from '@angular/forms';
并在进口数组中:
imports: [
....
FormsModule,
ReactiveFormsModule,
....
],
这是我得到的错误:
错误错误:表单控件的值访问器没有名称:&#39; radio&#39; at _throwError(forms.js:2432) at setUpControl(forms.js:2302) 在FormGroupDirective.addControl(forms.js:6658) 在FormControlName._setUpControl(forms.js:7308) 在FormControlName.ngOnChanges(forms.js:7221) 在checkAndUpdateDirectiveInline(core.js:12365) at checkAndUpdateNodeInline(core.js:13893) at checkAndUpdateNode(core.js:13836) 在debugCheckAndUpdateNode(core.js:14729) 在debugCheckDirectivesFn(core.js:14670)
有什么想法吗?
答案 0 :(得分:2)
我已经弄明白了。我所要做的就是将它添加到我顶部的app.module.ts:
import { ButtonsModule } from 'ngx-bootstrap';
这在我的进口中:
imports: [
....
FormsModule,
ReactiveFormsModule,
ButtonsModule,
....
]
