我需要使用反应式表格angular2来检查密码和确认密码字段是否具有相同的值.我确实在这里看到了很多答案,Angular 2表格验证了重复密码,比较验证器中的字段和angular2,但似乎没有人对我有用.有人请帮忙."这个"在我的验证函数中是未定义的: (.分享我的代码,

this.addEditUserForm = this.builder.group({
            firstName: ['', Validators.required],
            lastName: ['', Validators.required],
            title: ['', Validators.required],
            email: ['', Validators.required],
            password: ['', Validators.required],
            confirmPass: ['', [Validators.required, this.validatePasswordConfirmation]]
        });
validatePasswordConfirmation(group: FormGroup): any{
        let valid = true;
        // if (this.addEditUserForm.controls.password != this.addEditUserForm.controls.confirmPass) {
        //     valid = false;
        //     this.addEditUserForm.controls.confirmPass.setErrors({validatePasswordConfirmation: true});
        // }
        return valid;
    }
