推荐答案

我在您的代码中做了一些更改，并编写了一个javascript函数来查找选中的值
请检查

I have changed a bit in your code and written a javascript function to find checked value
plz check

function getSelectedMember(field, count)
{
  var icount = document.getElementById(count).value;
  for (var i = 0; i <icount; i++)
  {
    if (document.getElementById(field + i).checked == true)
    {
      alert(document.getElementById(field + i).value);
      //You can use this value
     }
   }
}

<div id="friend-list">
               <h3>Grouop Member</h3>
                    <div style="height:190px; width:250px;margin-removed10px; text-align:left " id="Group-list">
         <% if (groMoney.Services.UserGroupMemberSevices.get_grpMemberList(groMoney.Services.GroMoneyUserMemberService.getCurrentUser()).Rows.Count != 0)
            {int i=0; %> 
            <% foreach (System.Data.DataRow MemberData in groMoney.Services.UserGroupMemberSevices.get_grpMemberList(groMoney.Services.GroMoneyUserMemberService.getCurrentUser()).Rows)
               {%>
               <ul>
                   <input id="check-name<%=i%>" type="checkbox" value="<%=MemberData[0]%>"title="Do you want to select member from group?" name="chk-name" /><%=MemberData[1]%>
               </ul>
            <% i++; //Added} %>
         <%} %>
                    </div>
                   <div class="lb-content-top">
<input type="text" id="txt" value="<%=i%>" style="visibility:hidden" /> //ADDED
                     <input class="button" style="cursor: pointer;left:20px;top: 2px;" type="button" value="View" name="delMember" tabindex="3" title="Delete selection"  önclick="getSelectedMember('check-name', 'txt')" />
                    </div>
             </div>
