我正在构建Ionic 2(typescript)应用程序。在复选框(ion-checkbox tag)中进行了简单的模型驱动表单验证后,发现问题仅限。表单验证不适用于Ionic 2中的Angular 2 FormBuilder
我正在使用FormBuilder构建表单模块。我希望表单根据复选框输入控件的选中状态进行验证/未验证。但它的工作只有单向。这里是我的代码:
reg.html
<ion-content padding>
<form class="client_profile" [formGroup]="regForm">
<div class="profile_pic" id="profile_pix">
<img src="build/images/home.svg" id="client_camera_pic" />
</div>
<ion-item>
<ion-label floating>What we would call you?</ion-label>
<ion-input type="text" formControlName="client_name"></ion-input>
</ion-item>
<ion-item>
<ion-label floating>Choose your username</ion-label>
<ion-input type="text" name="client_username" value="" #client_username formControlName="client_username"></ion-input>
</ion-item>
<ion-item>
<ion-label floating>Where we will drop your Email?</ion-label>
<ion-input type="email" name="client_email" value="" #client_email formControlName="client_email"></ion-input>
</ion-item>
<ion-item>
<ion-label floating>We also need your phone number</ion-label>
<ion-input type="number" name="client_phone" value="" #client_phone formControlName="client_phone"></ion-input>
</ion-item>
<ion-item class="reg_terms">
<ion-checkbox secondary #terms name="terms" value="" checked="false" formControlName="terms"></ion-checkbox>
<ion-label>I accept the <a href="#">Terms & Conditions</a></ion-label>
</ion-item>
</form>
<div>
<ion-buttons right class="client_reg_done">
<button danger class="reg_complete" (click)="process_client_reg()" [disabled]="!regForm.valid">NEXT</button>
</ion-buttons>
</div>
</ion-content>
reg.ts
import { Component, ViewChild, ElementRef } from '@angular/core';
import { FORM_PROVIDERS, FormBuilder, FormControl, FormGroup, AbstractControl, Validators, REACTIVE_FORM_DIRECTIVES } from '@angular/forms';
import { App, NavController, ViewController, ModalController, LoadingController, LoadingOptions } from 'ionic-angular';
@Component({
templateUrl: "build/pages/registration/reg.html"
})
export class Registration {
ngAfterViewInit(){
}
regForm: FormGroup;
constructor(public app: App, public nav: NavController, public viewCtrl: ViewController, public elem: ElementRef, public modalCtrl: ModalController, public loading: LoadingController, public fb: FormBuilder){
}
ngOnInit() {
this.regForm = this.fb.group({
client_name: ['', Validators.compose([Validators.required, Validators.maxLength(30), Validators.pattern('^[a-zA-Z\. ]+$')])],
client_username: ['', Validators.compose([Validators.required, Validators.maxLength(20), Validators.pattern('[a-zA-Z0-9-_\.]+')])],
client_email: ['', Validators.compose([Validators.required, Validators.pattern('^[a-zA-Z0-9-_][email protected][a-zA-Z]+\.[a-zA-Z]{2,4}$')])],
client_phone: ['', Validators.compose([Validators.required, Validators.pattern('^[\+0-9]{10,12}$')])],
terms: [null, Validators.required]
});
}
}
实际视图:
检查/取消条款&条件复选框不会更新验证逻辑,并且'NEXT'按钮的禁用状态不会更新。它的表单验证没有考虑这个复选框。一些帮助表示赞赏。
