通过键盘访问复选框 [英] Checkbox access by keyboard

问题描述

我正在创建一个登录页面，并希望通过使用键盘让用户灵活地控制焦点。我正在使用AccessKey，但它似乎无法正常工作。任何帮助将不胜感激。



以下是我的电子邮件HTML字段。

I am creating a login page and want to give user the flexibility to control the focus by using keyboard. I am using AccessKey but it seems not working. Any help will be appreciated.

Below is my HTML for Email field only.

<table>
    <tr>
      <td>
          <div class="loginLabel">
                <span class="emailPasswordText">Email</span>
          </div>
          <asp:TextBox ID="txtUserName" runat="server"
               TabIndex="1" CssClass="inputCredential" MaxLength="60"
               AccessKey="E">
           </asp:TextBox>
      </td>
   </tr>
</table>
<pre lang="text">

我尝试在Mozilla中使用Alt + E和Ctrl + E Firefox。

I tried by using Alt+E and Ctrl+E in Mozilla Firefox.

推荐答案

您可以检查这些来控制键盘上的事件：

http://msdn.microsoft.com/en-us/library/ms171538.aspx [ ^ ]

http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keypress.aspx [ ^ ]

正如您在问题标题中提到的复选框，是否要从键盘中选择并取消选择？如果是，那么您可以使用：

You can check these to control events from keyboard:

http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keypress.aspx[^]
As you mentioned checkbox in problem title,do you want to select and deselect it from keyboard?If that,then you can use:

private bool YesKey = false
     private void Form1_KeyPress(object sender, KeyPressEventArgs e)
     {
         if (YesKey)
         {
             chkbox1.Checked = true;
         }
         else
         {
             //uncheck it
         }
     }

     private void Form1_KeyDown(object sender, KeyEventArgs e)
     {
         if (e.KeyCode == Keys.Y)
         {
             YesKey = true;
         }
     }
