JS定时跳转

    <script type="text/javascript"> 
       window.onload = function () {
            setInterval(function () {
                document.getElementById('txt1').value++;
                if (document.getElementById('txt1').value == 10) {
                    location.href = 'http://www.luofenming.com';
                }
            },1000)
        }
    </script>
 //setTimeout用法也差不多 不过 只是执行一次

    <input id="txt1" type="text" value="0">
