. 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; // 倒數十下
$(function() {
timeout = setTimeout(BtnCount, 1000); // 1s執行一次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 id="form1" runat="server">
<div>
<asp:Button ID="btnSubmit" runat="server" Text="確定" Enabled="false"
onclick="btnSubmit_Click"/>
</div>
</form>
</body>
setTimeout預設只執行一次，但我們可以用遞歸，是它自己啟動自己。
