推荐答案

您可以这样做

You can do like that

function button1()
{
    document.getElementById(''<%= Button1.ClientID%>'').focus()
}
function button2()
{
    document.getElementById(''<%= Button2.ClientID%>'').focus()
}

并在文本框的"onblur"事件上调用这些函数，例如

and call these functions on "onblur" event of the textbox like

<asp:textbox id="TextBox1" runat="server" onblur="button1()" xmlns:asp="#unknown" />

编写JavaScript函数并处理文本框的keyup事件.检查KeyCode是否为13(即按下输入按钮)，调用相应的按钮单击事件.

尝试一下！

Write a JavaScript function and handle the keyup event of the textbox. Check if the KeyCode is 13 (i.e) enter button is pressed, call the corresponding button click event.

Give it a try!

如果要在文本框中按Enter，请参见下文-vb.net

假设button2具有您要调用的代码-通过在文本框中按Enter键

这是一种简单的方法

公告-Textbox1_keydown

If you want to press enter in a textbox - see below - vb.net

Let''s say that button2 has the code you want to call - by pressing enter in a textbox

This is an easy way to do it

notice - Textbox1_keydown

Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
   If (e.KeyCode = Keys.Enter) Then Button2.PerformClick()
End Sub
