指令碼代碼： 複製代碼 代碼如下:<head runat="server">
<title>Recipe2</title>
<script src="Scripts/jquery-1.4.1-vsdoc.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$("input:text:first").focus(); // TextBox轉換成html控制項為<input type="text"/>
$("input:text").bind("keydown", function (e) {
if (e.which == 13) { // 擷取Enter索引值
e.preventDefault(); // 阻止表單按Enter鍵預設行為，防止按斷行符號鍵提交表單
var nextIndex = $("input:text").index(this) + 1;
$("input:text")[nextIndex].focus();
}
});
$("#<%=btnReset.ClientID%>").click(function () {
$("form")[0].reset();
});
