 </head>
 <body>
 <p style="text-align:center;">
  当前时间：<input type="text" name="timeBox" id="time" />

 function showLeftTime() {  
 var now = new Date();

 var day = now.getDate();  
 var hours = now.getHours();  
 var minutes = now.getMinutes();

 } 
 
 </script> 
 </head>
 <body onload="showLeftTime()">
