<body>
<input type='checkbox' name='likes' value='music'></input><span>音樂</span>
<input type='checkbox' name='likes'></input><span>美術</span>
<input type='checkbox' name='likes'></input><span>資訊科技</span>
<input type='checkbox' name='likes'></input><span>運動</span>
<input type='radio' name='other'><span>單選</span></input>
<script src="js/jquery-1.6.4.min.js"></script>
<script>
var hobbies;
$("input[name=likes]").change(function(){
hobbies='';
//console.log($(this)[0].checked);
$("input:checked[name=likes]").each(function(index){
console.log($(this).next('span'));
if($(this)[0].checked){
hobbies+=$(this).next('span').text();
hobbies+=",";
}
});
console.log(hobbies.slice(0,-1));
});
</script>

若把放裡，用$.fn.children('span')(為空)並不能獲得span。
ps:用jquery可以獲得checkbox的value屬性的值（預設為on, val()），其text(),htm()獲得的值都是空字串。
