需要单击两次才能激活文本框 [英] Need click twice to active a textbox

问题描述

在aspx页面中，有几个文本框（例如txtBoxA和txtBoxB）。理想情况下，在txtBoxA中输入值后，单击TAB和RETURN键将激活txtBoxB。但是，最初加载页面时，需要单击两次才能激活txtBoxB。如何调试此问题？谢谢。

相关代码如下：

In am aspx page, there are a couple of textbox (e.g. txtBoxA and txtBoxB). Ideally, after entering values in txtBoxA, clicking a TAB and RETURN key will make txtBoxB activated. However, when the page is initially loaded, it needs to click twice to activate txtBoxB. How can this problem be debugged? Thanks.

            <asp:TextBox ID="txtUser" runat="server" Font-Size="Small"  AutoPostBack="true"
                TabIndex="2" onkeydown="onFocus(event);"
                Text =""
                ></asp:TextBox>
        </td>
    </tr>
    <tr>
        <td class="style1">
            <asp:TextBox ID="txtPassword" ClientID="txtPassword" runat="server" Font-Size="Small" AutoPostBack="true"
                TextMode="Password" TabIndex="3" >
            </asp:TextBox>
        </td>

    function onFocus(event) {
        var e1 = document.getElementById('<%=txtUser.ClientID%>').value;
        if (e1.length > 5) {
            if (event.keyCode == 13) {      // RETURN
                event.keyCode = 9;
                return event.keyCode;
            }
        }
    }
    </tr>
</table>

推荐答案

标签会移动关于链接等事情。如果默认的Tab键顺序不适合您，请尝试使用tabindex定义您自己的选项卡

Tab will move on to things like links etc too. If the default tab order isn't working for you, try defining your own using tabindex
