【问题描述】：
我之前问过一个关于 JavaScript 代码的问题，您可以在这里看到它：How can I scroll down to a multiline TextBox's bottom line, Javascript's scrollIntoView is not working for this。好吧，它已经解决了，并且接受的答案正在起作用。
之后，我不得不将您在该问题中看到的代码部分移动到最终看起来像这样的用户控件：
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="LiveChatPart.ascx.cs" Inherits="BeyzamComArayuz.LiveChatUserControl.LiveChatPart" %>
<%@ Register src="/LiveChatUserControl/GenelOdaFlashPart.ascx" tagname="GenelOdaFlash" tagprefix="gOF" %>
<script language="javascript" type="text/javascript">
function buttonClicked() {
// var el = document.getElementById("TxtBxOdaMesajlari");
var textBox = $get("TxtBxOdaMesajlari");
textBox.scrollTop = textBox.scrollHeight;
// $get("TxtBxOdaMesajlari").scrollIntoView("false");
}
</script>
<asp:ScriptManager ID="ScrptMngr" runat="server"></asp:ScriptManager>

在 asp.cs 文件中我有
protected void BttnGonder_click(object sender, EventArgs e)
{
string cariId = "";
if (KullaniciTuru == 1)
{
cariId = Session["ModelId"].ToString();
}
else
{
cariId = Session["UyeId"].ToString();
}
string uyeHesapAdi = BAL.Cari.Cari.GetCariHesapAdi(int.Parse(cariId));
string mesaj = uyeHesapAdi + " : " + TxtBxMesaj.Text;
TxtBxOdaMesajlari.Text = TxtBxOdaMesajlari.Text + Environment.NewLine + mesaj;
//TxtBxOdaMesajlari.Focus();
ScriptManager.RegisterStartupScript(this, this.GetType(), "txtbxmesajlarslide", "buttonClicked();", true);
TxtBxMesaj.Text = string.Empty;
}
我的问题是buttonClicked() 功能不再起作用，我尝试使用ScottS's answer 中的Page.ClientScriptManager.RegisterClientScriptInclude 和这个Page.ClientScript.RegisterClientScriptBlock，它们都不起作用。我该怎么办？
编辑：我尝试使用 IE9 的内置调试器调试网页，并在 buttonClicked() 函数中设置断点，但从未命中。然后我使用了按钮的 OnClientClick 事件并为其添加了 buttonClicked 函数，它适用于每次点击，但随后文本框会跳回到 buttonClicked() 函数之前的位置。
