Or for cleaner mark-up, bind the event in code-behind at PageLoadlike this
或者为了更清晰的标记，PageLoad像这样在代码隐藏中绑定事件
if (!IsPostBack)
{
string script = String.Format("GetTextBoxValue('{0}')", rowID.ClientID);
Click.Attributes.Add("onclick", script);
}
Now your mark-up can be like this.
现在您的标记可以是这样的。
<asp:TextBox ID="rowID" runat="server"> </asp:TextBox>
<asp:Button ID="Click" runat="server" />
