web页面下TextBox控件下得到焦点

Question

script language="javascript">
  document.getElementById("txt1").focus(); 
</script>

Answer 1

你在页面的Page_Load方法中写这么一段代码：
if(!Page.IsStartupScriptRegistered("dgscript"))
Page.RegisterStartupScript("dgscript","<script Language=\"Javascript\">document.all."+this.TextBox.ClientID.Trim()+".focus()</script>");

Answer 2

RegisterStartupScript("getFocus",<script>document.all.control.focus();</script>");
