ASP.Net MVC - 处理多个复选框 [英] ASP.Net MVC - Handle Multiple Checkboxes

问题描述

好吧，我有一个适当的基于角色的权限系统，并希望管理员对能够编辑权限，每个角色。要做到这一点，我需要装载大量的复选框，但是我从视图

Ok, I have a role based permission system in place and would like admin's to be able to edit the permissions for each role. To do this I need to load lots of checkboxes, however I'm struggling with getting the return data from the View

请注意：我环顾四周，我也发现了类似的问题，但由于目前还找不到一个解决方案

Please Note: I have looked around, I have found similar questions but as of yet cannot find a solution.

 <%
     Html.BeginForm();

    string lastGroup = "";
    foreach (var CurPermission in Model)
    {

%>
        <%=Html.CheckBox("Permissions", CurPermission.Checked, new { ID = CurPermission.PermissionId}) + " " + CurPermission.PermissionValue%> 

        <br />
<%
    } 
    %>
        <input type="submit" value="Submit" />
    <%
    Html.EndForm();
%>

和控制器，

[AcceptVerbs(HttpVerbs.Post)]
        public ActionResult EditPermissions(String[] Permissions)
        {
            foreach (var CurPermission in Permissions)
            {
                Debug.WriteLine(CurPermission);
            }

            return View();
        }

很显然，我需要知道哪些箱不检查，以及是的人。但是因为整个的（真，假）的返回值我不能工作，这值与该复选框。

Obviously I need to know which boxes are not checked as well as the ones that are. But in the return values because of the whole ("true,false") I cant work out which value relates to which checkbox.

以修复或$ P $有什么建议phaps另一种方法将appriciated。

Any suggestions as to a fix or prehaps an alternate method would be appriciated.

推荐答案

下面是code的一些片段，我们使用成员分配给项目，希望这可以帮助你！

Here are some snippets of code that we use to assign members to a project, hopefully this helps you out!

在我们的观点：

<p>
    <label>
       Select project members:</label>
    <ul>
        <% foreach (var user in this.Model.Users)
           { %>
        <li>
            <%= this.Html.CheckBox("Member" + user.UserId, this.Model.Project.IsUserInMembers(user.UserId)) %><label
                for="Member<%= user.UserId %>" class="inline"><%= user.Name%></label></li>
        <% } %></ul>
</p>

在控制器中，我们有：

// update project members	
foreach (var key in collection.Keys)	
{	
	if (key.ToString().StartsWith("Member"))
	{
		int userId = int.Parse(key.ToString().Replace("Member", ""));	
		if (collection[key.ToString()].Contains("true"))	
			this.ProjectRepository.AddMemberToProject(id, userId);
		else
                        this.ProjectRepository.DeleteMemberFromProject(id, userId);
	}
}

主要的事情与HTML复选框助手工作时，记得是使用含有（）来判断真或假的。

The main thing to remember when working with the Html Checkbox Helper is to use contains() to determine true or false.
