专注于PostBack [英] Giving Focus on PostBack
问题描述
我有一个页面，我将焦点放在页面上的第一个文本框中：
< body onLoad =" document.forms [0] .firstName.focus（） ;">
当我退出
我的屏幕上的第3个文本框时，我也去检查一些数据的状态。
问题是当页面回发时，屏幕跳回到第一个文本框，因为
onLoad语句。有没有一种简单的方法来
告诉它只进行一次Onload并转到重新发布的下一个文本框？
谢谢，
Tom
我想这就是你想要的......
Private Sub Page_Load（ByVal sender As System.Object，ByVal e As
System.EventArgs）处理MyBase.Load
如果不是IsPostBack那么
< body onLoad =" document.forms [0] .firstName.focus（）;">
结束如果
End Sub

我尝试了但是得到了错误：
编译器错误消息：BC30636：''>''预计。
我的代码是：
Sub Page_Load（发送者为对象，e为EventArgs）
，如果不是IsPostBack然后
< body onLoad =" document.forms [0] .firstName.focus（）;">
结束如果

< blockquote>您好。
添加Runat =" server"和id =" myBody"到aspx文件中的body标签。然后
把它放在你的代码中：
受保护的WithEvents myBody As System.Web.UI.HtmlControls.HtmlGenericControl
现在你可以在你的页面加载方法中添加javascript，如下所示：
如果不是IsPostBack那么
myBody.Attributes.Add（" onLoad"，
" document.forms [0] .the_id_of_the_first_textbox.focus（）;"）
结束如果

I have a page where I give focus to the first textbox on my page:
<body onLoad="document.forms[0].firstName.focus();">
I also go and check the status of some data when I exit the 3rd textbox on
my screen.
The problem is that the screen jumps back to the first textbox because of
the onLoad statement when the page is posted back. Is there an easy way to
tell it to do the Onload only once and to go the next textbox on the repost?
Thanks,
Tom
I think this is what you want....
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
If Not IsPostBack Then
<body onLoad="document.forms[0].firstName.focus();">
End If
End Sub

Hi.
Add a Runat="server" and id="myBody" to the body tag in the aspx file. Then
put this in your code behind:
Protected WithEvents myBody As System.Web.UI.HtmlControls.HtmlGenericControl
Now you can add the javascript in you page load method, like this:
If Not IsPostBack Then
myBody.Attributes.Add("onLoad",
"document.forms[0].the_id_of_the_first_textbox.focus();")
End If
