表单提交
<script>  
 function   my() 
 { 
 	f=document.myform; 
 	if(f.ming.value== " ") 
 	{ 
 		alert( "请填写完整! "); 
 		f.ming.focus(); 
 		return   false; 
 	} 
 	return   true; 
 var   ming=f.ming.value; 
 	document.write( " <h2> 您的注册信息如下: </h2>  "); 
 	document.write( " <hr>  ");	 
 	document.write( " <br> 物业名称: "+ming); 
 } 
  </script>  
  </head>    
 我的表单提交后怎么就刷新了一下,就没有显示注册的信息啊? 
  <body   bgcolor= "#CAE4FF ">  
  <h1   align= "center ">  <font   color= "#0033FF "   face= "华文彩云 "> 请输入房源信息 </font>  </h1>  
  <form   name= "myform "   onSubmit= "return   my() ">  
  <table   bgcolor= "#CAE4FF "   align= "center "   border= "2 ">  
  <tr>  
 	 <td> 物业名称: <input   type= "text "   name= "ming "   value= " ">  </td>  
  </tr>  
  </table>  
  <p   align= "center ">  <input   type= "submit "   name= "cheng "   value= "完成 ">        
  <input   type= "reset "   name= "chong "   value= "重写 ">  </p>  
  </form>  
  </body>
