Jqmodal在Updatepanel中不起作用

问题描述

我有一个名为raise_alarm()的方法，该方法显示基于jquery的消息框.但是，当我从Updatepanel内部的控件事件(例如，提交按钮)中调用此方法时，它将无法正常工作.相关代码如下.我该如何解决?

I have a method named raise_alarm() which, show a message box based on jquery. But when I call this method from an event of a control(such as submit button) which is inside of Updatepanel, it isn't working. Related codes are below. How can I fix it?

 Public Sub Raise_Alarm(ByVal p_Page As Page, ByVal p_Message As String, Optional ByVal p_IsError As Boolean = True)
        Dim strScript As String
        strScript = "$(function() { Mesaj('" & p_Message & "'); });" & ControlChars.NewLine
        p_Page.ClientScript.RegisterStartupScript(p_Page.GetType(), "alert", strScript, True)
end sub

Private Sub dtlQuestion_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles dtlQuestion.ItemCommand
        If Not User.Identity.IsAuthenticated Then
            Raise_Alarm(Me, "Giriş Yapmadan Oy Veremezsiniz")
            Exit Sub
        End If
end sub

推荐答案

您必须使用ScriptManager而不是p_Page.ClientScript.

示例.我在您的代码中将p_Page.ClientScript替换为ScriptManager.

EDIT : Example. I replaced p_Page.ClientScript by ScriptManager in your code.

Public Sub Raise_Alarm(ByVal p_Page As Page, ByVal p_Message As String, Optional ByVal p_IsError As Boolean = True)
        Dim strScript As String
        strScript = "$(function() { Mesaj('" & p_Message & "'); });" & ControlChars.NewLine
        ScriptManager.RegisterStartupScript(p_Page.GetType(), "alert", strScript, True)
end sub

Private Sub dtlQuestion_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataListCommandEventArgs) Handles dtlQuestion.ItemCommand
        If Not User.Identity.IsAuthenticated Then
            Raise_Alarm(Me, "Giriş Yapmadan Oy Veremezsiniz")
            Exit Sub
        End If
end sub

ClientScript未启用Ajax，ScriptManager知道如何处理部分回发.请快速浏览有关msdn的文章.

ClientScript is not ajax enabled, ScriptManager knows how to deal with partial postbacks. Please have a quick look at this article on msdn.
