------解决方案-------------------- <script>  
 function check() 
 { 
 	o = document.f.getElementsByTagName( "input "); 
 	checks = new Array(); 
 	for(c=0; c <o.length; c++) 
 	{ 
 		if(o[c].type== "checkbox " && o[c].checked) checks[checks.length]=o[c].value; 
 	} 
 	alert( "选择了: "+checks); 
 	return false; 
 } 
  </script>  
  <form name= "f " onsubmit= "return check() ">  
  <input type= "checkbox " name= "c " value= "1 "> 1 
  <input type= "checkbox " name= "c " value= "2 "> 2
