js局部刷新页面时间具体实现

复制代码 代码如下:
<head>
    <title></title>
    <script type="text/javascript">
        function GetTime() {
            var time = new Date();
            var year = time.getFullYear();
            var month = time.getMonth() + 1;         // 月份从0开始
            var day = time.getDate();                // 注意是getDate()
            var hour = time.getHours();
            var minute = time.getMinutes();
            var sec = time.getSeconds();
            var timestring;
            if (minute < 10) {
                timestring
                    = year + "-" + month + "-" + day + " " + hour + ":0" + minute + ":" + sec;
            }
            else {
                timestring
                    = year + "-" + month + "-" + day + " " + hour + ":" + minute + ":" + sec;
            }
            // div没有value属性
            document.getElementByIdx_x("timeDiv").innerHTML = timestring;
            window.setInterval("GetTime()", 1000);
        }
    </script>
</head>
<body onload="GetTime()">
    <div id="timeDiv">
    </div>
</body>
