我试图像下面的示例和它的作品。如果您有任何其他问题，请告知我。

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> 
<p> 
    <asp:TextBox ID="txtemail" runat="server"></asp:TextBox> 
    <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" /> 

</p>

的按钮，点击该代码隐藏是

protected void Button1_Click(object sender, EventArgs e) 
    { 
     String name, gender, DOB, email, mob, land, address, state, city, pincode; 
     email = txtemail.Text.Trim(); 
     Response.Write("<script> alert('" + email + "')</script>"); 
    }

此外，调试代码，并找到，如果你的txtemail控制得值。

如果你想弹出你的警报电子邮件ID，你可以试试下面的代码

protected void Button1_Click(object sender, EventArgs e) 
{ 
    String name, gender, DOB, email, mob, land, address, state, city, pincode; 
    email = txtemail.Text.Trim(); 
    ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('"+ email "');", true); 
}

尝试...
