我正在构建一个带有包含日志消息的文本框的网站.使用 AJAX 更新日志.
I'm building a website with text box containing log messages. the log is getting updated using AJAX.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" >
<ContentTemplate>
<asp:TextBox ID="TextBox1" runat="server"
onload="textbox_load"
Height="110px"
TextMode="MultiLine"
Width="100%">
</asp:TextBox>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
</Triggers>
</asp:UpdatePanel>
每次更新时我都需要向下滚动文本框.怎么样?
I need to scroll the text box down every time it gets updated. How?
处理Sys.WebForms.PageRequestManager.endRequest 事件并向下滚动文本框:
Handle the Sys.WebForms.PageRequestManager.endRequest event and scroll the textbox down:
var tbox = $get('<%= TextBox1.ClientID %>');
tbox.tbox.scrollTop = tbox.scrollHeight;
