我在角度 7 上工作
我比较旧密码和新密码
如果两个都相同,则必须显示错误
但在我的情况下,旧密码和新密码相同但不显示错误
为什么不显示错误以及如何解决此问题?
当新旧值相同但不显示错误时,函数 CompareOldWithNew 返回 false
更改密码.ts
oldPassword = new FormControl('', [Validators.required, Validators.minLength(6), Validators.maxLength(10)]);
newPass = new FormControl('', [Validators.required, Validators.minLength(6), Validators.maxLength(10),this.CompareOldWithNew("oldPassword")]);
ngOnInit() {
this.createFormResetPassword();
}
get c() { return this.ChangePasswordForm.controls; }
CompareOldWithNew(field_name): ValidatorFn {
return (control: AbstractControl): { [key: string]: any } => {
const input = control.value;
const isnotequalValues = control.root.value[field_name] != input;
return isnotequalValues ? null :{'old password must not match New': {isnotequalValues}} ;
};
}
createFormResetPassword() {
this.ChangePasswordForm = this.formBuilder.group({
oldPassword: this.oldPassword,
newPass: this.newPass
})
}
onSubmit() {
if (this.ChangePasswordForm.invalid) {
return;
}
