获取MVC 4中的复选框值 [英] Getting checked checkboxes value in MVC 4

问题描述

我的视图中有4个复选框，这些复选框是动态生成的，因为数据库中存在的值。所以在点击提交按钮时我想保存所有选中的复选框的值。请让我知道这方面的解决方案

推荐答案

< input type =checkboxname =selectedRolesid =chkRolesvalue =@ role.RoleID>

@foreach（userRoles中的var userRole）

{

if（userRole.UserID == curID&& role.RoleID == userRole.RoleID）< br $>
{



isChecked2 = true;

@（Html.Raw（isChecked2？checked = \）已检查\：））

}

}

/>



如果您在运行时运行代码，请执行此操作名字字段将获得您选择的角色

然后将您的控制器写成这样的东西



[HttpPost]

[ValidateAntiForgeryToken]

public ActionResult Edit（[Bind（Include =UserID，Name，Email）]用户用户，string [] selectedRoles，string userRoleID）

{< br $>




int s = Convert.ToInt32（user.UserID）;



if（ModelState.IsValid）

{



foreach（selectedRoles中的var项目）

{

userRole.RoleID = Convert.ToInt32（item）;



db.UserRole.Add（userRole）;

db.SaveChanges（）;

}

}





ViewBag。 RoleID = new SelectList（db.Roles，RoleID，RoleName，user.RoleI D）;

返回查看（用户）;

}< / input>

<input type="checkbox" name="selectedRoles" id="chkRoles" value="@role.RoleID">
@foreach (var userRole in userRoles)
{
if (userRole.UserID == curID && role.RoleID == userRole.RoleID)
{

isChecked2=true;
@(Html.Raw(isChecked2 ? "checked=\"checked\"" : ""))
}
}
/>

In this if you run the code at runtime name field will get your selected roles
then write your controller as something like this

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit([Bind(Include = "UserID,Name,Email")] User user, string[] selectedRoles,string userRoleID)
{


int s=Convert.ToInt32(user.UserID);

if (ModelState.IsValid)
{

foreach (var item in selectedRoles)
{
userRole.RoleID = Convert.ToInt32(item);

db.UserRole.Add(userRole);
db.SaveChanges();
}
}


ViewBag.RoleID = new SelectList(db.Roles, "RoleID", "RoleName", user.RoleID);
return View(user);
}</input>
