推荐答案
您只需将javascript放在表单上，并将其直接呈现到html中.然后，您可以将事件处理程序等置于控件中，框架无法识别的任何内容都将通过逐字记录传递.
You just put the javascript on the form and it''s rendered directly into your html. Then you can put event handlers etc in your controls, any thing not recognised by the framework is passed through verbatim.
尝试一下....
Try this....
<form runat="server">
<script type="text/javascript" language="javascript">
//put javascript here
<table>
<tr>
<td>Name:</td>
<td><asp:TextBox ID="name" runat="server" /></td>
</tr>
<tr>
<td>Roll:</td>
<td><asp:TextBox ID="roll" runat="server" /></td>
</tr>
<tr>
<td><asp:ImageButton ID="ImgSubmit" runat="server" ImageUrl="~/images/submit.gif"/></td>
</tr>
</table>
</form>

JavaScript是客户端脚本，主要用于验证.
您可以在< HEAD>下编写脚本标签
将光标放在文本框上的功能
Javascript is client side scripting mostly used for validation.
U can write a script under <HEAD> tag
Function to put cursor on textbox
function putFocus()
{
document.getElementById("TextboxID").focus();
return false;
}
调用html正文标签的加载上的函数
call the function on Load of html Body tag
<body onload="return putFocus()"></body>
