我在角度4中声明了反应性
this.userForm = this.fb.group({
"id": [user ? user.id : ""],
"profile": this.fb.group({
"email": [user && user.profile.email ? { value: user.profile.email, disabled: true } : "", Validators.compose([Validators.required, Validators.email])],
}),
"username": [user && user.username ? { value: user.username, disabled: true } : "", Validators.compose([Validators.required, GlobalValidator.usernameFormat])],
})
默认情况下,如果我的表单填写了表单字段被禁用的数据(电子邮件,用户名)。 我面临的问题是,如果我刷新页面,表单字段就会启用。
(修改)
ngOnInit() {
this.buildForm()
if (this.activatedRoute.snapshot.params.id) {
this.service.getUser(Number(this.activatedRoute.snapshot.params.id)).subscribe((user) => {
this.buildForm(user)
})
}
}
buildForm(user?:any){
this.userForm = this.fb.group({
"id": [user ? user.id : ""],
"profile": this.fb.group({
"email": [user && user.profile.email ? { value: user.profile.email, disabled: true } : "", Validators.compose([Validators.required, Validators.email])],
}),
"username": [user && user.username ? { value: user.username, disabled: true } : "", Validators.compose([Validators.required, GlobalValidator.usernameFormat])],
})
}

解决此问题我更改了我的代码:
之前:
"username": [user && user.username ? { value: user.username, disabled: true } : "", Validators.compose([Validators.required, GlobalValidator.usernameFormat])],
之后:
this.userForm = this.fb.group({
username : this.fb.control("")
})
if(user){
this.userForm.get("username").setValue(user.username)
this.userForm.get("username").disable()
}

我遇到了同样的问题,但是调用this.userForm.get(“ username”)。disable()并没有解决它,因为我正在重新加载我的视图(使用router.navigate())。
就我而言,我必须在重新加载之前重置表单:
this.userForm =未定义; this.router.navigate([path]);
