关于javascript:RazorPage复杂Model绑定自定义类型属性-CheckboxList

这里是援用
自定义类型属性

很多时候，咱们在PageModel中会搁置一个或多个自定义类型属性（又被称之为Model）

Register是一个自定义的类：

public class Register{    public string UserName { get; set; }    public string Password { get; set; }}

这样的属性是怎么被绑定赋值的？

咱们须要给FormData一个用点（.）分隔非凡格局的name：

比方，Regiter.UserName。这样ASP.NET进行Model绑定时，会主动将其解析为：Register属性的UserName值。
点（.）的档次没有限度，比方Register.User.Name会被解析为：Register属性中的User属性中的Name值。
@想一想@：为什么应用 input TagHelper 时，生成的原生HTML代码name是这样的值？

留神：TagHelper为咱们的Model绑定带来了便当，然而

TagHelper自身 没有魔力，没有魔力，没有魔力！重要的事说三遍，^_^

肯定要了解：TagHelper和Model绑定之间没有关系，没有TagHelper一样能够进行Model绑定

CheckboxList汇合绑定

foreach和for

@for (int i = 0; i < Model.Options.Count; i++)
{

<label>@i <input type="checkbox" asp-for="Options[i]" /></label><br />

}在PageModel中申明：

public IList<bool> Options { get; set; }

留神，不要应用foreach

@foreach (var item in Model.Options)
{

<label><input type="checkbox" asp-for="@item" /></label><br />

}
须要

public class Message{    public int Id { get; set; }    public bool Seleted { get; set; }}Id等不会主动传回PageModel

@for (int i = 0; i < Model.Messages.Count; i++)
{

<label>@i <input type="checkbox" asp-for="Messages[i].Seleted" /></label><input asp-for="Messages[i].Id" type="hidden" />    <br />

}
绑定的Model不是Entity
