Question

您好我无法预先显示屏幕上所有复选框的值。让我解释一下，我有5个复选框，例如2是增强而不是其他我想要一个包含所有5个复选框的数组，包括2个真和其他假有人可以帮助我。

与此同时我尝试做另一个我创建了一个类

的系统

public class PresenzaAO    
        (    
           public List <Presenti> listapresenti = new List <Presenti> ();    
            public string conteggiototale (get;)    
            public long idalunno (get;)    
           public string radio (get;)    
       )    

        public class Present    
        (    
           public string presents{get;set;}    
        )   
and then in the view I created this: 



<% Using (Html.BeginForm (ModificaPresenzaAlunno "," Presence ", FormMethod.Post))    
       (%>    
    <% = Html.Hidden ( "conteggiototale" Viewdata [ "conteggiototale"])%>    
   <% = Html.Hidden (idalunno "Viewdata [" student "])%>    
    <table>    
        <tr>    
            <td>    
                <% = Html.Encode (nomealunno)%>    
            </ td>    
            <td>    
                <% = Html.Encode (cognomealunno)%>    
            </ td>    
            <%    
                if (Viewdata [ "conteggio_presenze"]. ToString () == Viewdata ["conteggiototale"]. ToString ())    
               (%>    
           <td>    
               Absent    
                <input type = "radio" name = "radio" checked = "checked" id = "assente_"    
                    onclick = "getassentemod (<% = Viewdata [" student "]%>, 0);" value = "true_assente" />    
                  This    
                <input type = "radio" name = "radio" id = "presente_" value = "false_presente"    
                    onclick = "getassentemod (<% = Viewdata [" student "]%>, 0);" />    
           </ td>    
            <% Int i = 0;%>    
            <% Foreach (var p in (List <PresenzaAlunnoOra>) Viewdata [ "presenze_alunno"])    
               (    

                   i + = 1;    

            %>

            <%)%>    
            <%)    
                else    
                (%>    
            <td>

                    if (p.presente == true)    
                    (

将控制器参数PresenzaAO存在

我读了除复选框

之外的所有参数

Answer 1

不，它不包含空格，但我注意到在复选框名称中发布的示例中缺少某些内容说复选框的名称应如下所示：

<input type = "checkbox" id = "check_ <% = Viewdata [" pupil "]%>,<%= i%> "value ="<%= i%>" name = "Present [<% = i% >].presents"
                    onclick = "modificapresenzaalunno (this);" />

但我甚至不工作

从Checkbox获取价值
