好吧,我动态创建Asp.net验证控件,并将其插入到一个更新面板。 验证工作在IE和Firefox,但不是在Chrome或Safari。
这里是aspx文件。 不要问我为什么不使用一个按钮服务器控件...
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<div>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<asp:UpdatePanel ID="UpdatePanel1" UpdateMode="Always" runat="server">
<ContentTemplate>
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
<input id="Button1" type="button" value="submit" onclick='javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("Button1", "btnNext", true, "", "", false, true))' />
</ContentTemplate>
</asp:UpdatePanel>
</div>
这是后面的代码:
Dim Survey As New Survey
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Request("__EVENTARGUMENT") = "btnNext" Then
NextClick()
End If
Label1.Text = Date.Now.ToString
End Sub
Private Sub NextClick()
Survey.RenderPage(PlaceHolder1)
End Sub
这里是类:
Public Class Survey
Public Sub RenderPage(ByVal PlaceHolder As PlaceHolder)
Dim textbox As New TextBox
textbox.ID = "testing"
PlaceHolder.Controls.Add(textbox)
Dim val As New RequiredFieldValidator
val.ControlToValidate = textbox.ID
val.Text = "required"
val.EnableClientScript = True
PlaceHolder.Controls.Add(val)
End Sub
End Class
有没有人对如何让这个在Chrome和Safari浏览器工作任何想法?
