     <script language="JavaScript" type="text/javascript">

                 //时间显示在页面中哪个标签里,这里是其id
                 this.toShow = function (element) {
                     document.getElementById(element).innerHTML = format;
                 }
             }
    </script>

    调用

    <div id="time" >
    <script language="JavaScript" type="text/javascript" defer="defer">
