最佳答案
我有一些简单的角2分量与模板。如何清除表单和提交后的所有字段?.我无法重新加载页面。
设置后的数据与 date.setValue('')
字段仍然是 touched
。
import {Component} from 'angular2/core';
import {FORM_DIRECTIVES, FormBuilder, ControlGroup, Validators, Control} from 'angular2/common';
@Component({
selector: 'loading-form',
templateUrl: 'app/loadings/loading-form.component.html',
directives: [FORM_DIRECTIVES]
})
export class LoadingFormComponent {
private form:ControlGroup;
private date:Control;
private capacity:Control;
constructor(private _loadingsService:LoadingsService, fb:FormBuilder) {
this.date = new Control('', Validators.required);
this.capacity = new Control('', Validators.required);
this.form = fb.group({
'date': this.date,
'capacity': this.capacity
});
}
onSubmit(value:any):void {
//send some data to backend
}
}
Load-form. Component. html
<div class="card card-block">
<h3 class="card-title">Loading form</h3>
<form (ngSubmit)="onSubmit(form.value)" [ngFormModel]="form">
<fieldset class="form-group" [class.has-danger]="!date.valid && date.touched">
<label class="form-control-label" for="dateInput">Date</label>
<input type="text" class="form-control form-control-danger form-control-success" id="dateInput"
min="0" placeholder="Enter loading date"
[ngFormControl]="form.controls['date']">
</fieldset>
<fieldset class="form-group" [class.has-danger]="!capacity.valid && capacity.touched">
<label class="form-control-label" for="capacityInput">Capacity</label>
<input type="number" class="form-control form-control-danger form-control-success" id="capacityInput"
placeholder="Enter capacity"
[ngFormControl]="form.controls['capacity']">
</fieldset>
<button type="submit" class="btn btn-primary" [disabled]="!form.valid">Submit
</button>
</form>
</div>
