這篇文章介紹了Jquery倒數(shù)計時按鈕setTimeout的實例，有需要的朋友可以參考一下

復制代碼代碼如下:

<head runat="server">
    <title></title>
    <script type="text/javascript" src="js/jquery-1.3.2.js"></script>
    <script type="text/javascript">
        var timeout;
        var count = 10; // 倒數(shù)十下
        $(function() {
            timeout = setTimeout(BtnCount, 1000); // 1s執(zhí)行一次BtnCount
        });
        BtnCount = function() {
               // 啟動按鈕
               if (count == 0) {
                $('#btnSubmit').attr("disabled", "");
                $('#btnSubmit').val("確定");
                clearTimeout(timeout);           // 可取消由 setTimeout() 方法設置的 timeout
            }
            else {
                count--;
                $('#btnSubmit').val("確(" + count.toString() + ")定");
                setTimeout(BtnCount, 1000);
            }
        };
    </script>
</head>
<body>
    <form runat="server">
    <div>
        <asp:Button runat="server" Text="確定" Enabled="false"
           />
