我尝试将多个角度验证器参数[即Validators.minLength(8)和Validators.maxLength(12)]添加到我的表单中,我似乎无法使其工作......这些参数附加到(密码和密码c)实例在下面的代码中。有什么帮助吗?
export class signupComponent {
signupform: FormGroup;
constructor(public fb: FormBuilder) {
this.signupform = this.fb.group({
firstname: ['', Validators.required],
lastname: ['', Validators.required],
account: this.fb.group({
email: ['', Validators.required],
**password: ['', Validators.minLength(8), Validators.maxLength(12), Validators.pattern('[A-Za-z]{5}')],
passwordc: ['', Validators.minLength(8), Validators.maxLength(12), Validators.pattern('[A-Za-z]{5}')],
}, { validator: passwordMatcher }),**
shortbio: ['', Validators.required]
});
}
}

要支持多个验证器,您必须使用接受验证器数组的Validators.compose([])方法。在你的情况下:
password: ['', Validators.compose([Validators.minLength(8), Validators.maxLength(12), Validators.pattern('[A-Za-z]{5}')])]

password: ['', [Validators.minLength(8), Validators.maxLength(12), Validators.pattern('[A-Za-z]{5}')]]
这应该适合你。
