1.先构建杏彩源码出售 <Q> 2952777280【链接】 huaxianym.com 一个表单
this.form = this.fb.group({
Cust_Moblie: [null, [Validators.compose([this.saleService.mobileRegxValidator])], [this.mobilequeValidator]],
Cust_Tel: [null, [Validators.compose([this.saleService.telValidator])], [this.telValidator]],
Cust_QQ: [null, [Validators.compose([this.saleService.qqValidator])], [this.qqValidator]],
Cust_Wechat: [null, [Validators.compose([this.saleService.weChatValidator])], [this.weChatValidator]],
Cust_Email: [null, [Validators.compose([this.saleService.emailValidator])], [this.emailValidator]],
});
2.fromgroup的三个参数。官方文档还是要好好看的，当初就是面向百度编程，搜了好久才在百度上找到的解决方案
Cust_Email: [null, [Validators.compose([this.saleService.emailValidator])], [this.emailValidator]]
数组中第一项表示字段的默认值，null表示没有
数组第二项为一个数组，其中填写所需同步校验器的方法名，即不需要后台校验的校验方法
数组第三项仍为一个数组，其中填写所需异步校验器的方法名
第三点的异步验证会在同步验证通过之后再验证
3.同步邮箱验证
/**邮箱验证 */
emailValidator(control: FormControl) {
const val = control.value;
const mobieReg = regEx.email;
const result = val == "" || val == null ? true : mobieReg.test(val);
return result ? null : { Data: { info: '邮箱格式不正确' }, errors: true, required: true };
}
4.异步邮箱验证，判断是否已被注册
timers: any;
/**异步调用方法 */
asycValidateFunction(observer, val, field1, field2, functionName, timers) {
if (timers) {
clearTimeout(this.timers)
}
if (val == "" || val == null) {
observer.next(null);
observer.complete();
} else {
timers = setTimeout(() => {
this.http.get(CUSTOMER_DIC_VALUE.Customer[functionName], {
param: val, field1: field1, field2: field2
}).subscribe((data: any) => {
if (data.Code === 'fail') {
observer.next({ error: true, duplicated: true, Data: { info: data.Data } });
observer.complete();
}
else {
observer.next(null);
observer.complete();
}
})
}, 1000)
}
}
5.结合ng-zorror-ant的格式表现的验证提示信息
<nz-form-item class="mb-sm">
<nz-form-label [nzSm]="6" [nzXs]="24">Email</nz-form-label>
<nz-form-control [nzSm]="10" [nzXs]="24" nzHasFeedback>
<input nz-input formControlName="Cust_Email" placeHolder="Email">
<nz-form-explain *ngIf="
(form.get('Cust_Email')?.dirty && form.get('Cust_Email')?.errors) ||
form.get('Cust_Email')?.pending
">
<ng-container *ngIf="form.get('Cust_Email')?.hasError('required')">
{{form.getError('Data','Cust_Email')?.info}}
</ng-container>
<ng-container *ngIf="form.get('Cust_Email')?.hasError('duplicated')">
{{form.getError('Data','Cust_Email')?.info}}
</ng-container>
<ng-container *ngIf="form.get('Cust_Email')?.pending">
验证中...
</ng-container>
</nz-form-explain>
</nz-form-control>
</nz-form-item>
