一个简单的编程
<form action= " " method=post>
<input type= "checkbox " name= "a1 " value= "11 ">
<input type= "checkbox " name= "a2 " value= "11 ">
<input type= "checkbox " name= "a3 " value= "11 ">
<input type= "checkbox " name= "a4 " value= "11 ">
.
.
.
<input type= "checkbox " name= "a15 " value= "11 ">
</form>
==============================
请编一个程序循环获取这些值。
[解决办法]
使用同一个名字，获取的值会自动以逗号隔开。

<form action= " " method=post>
<input type= "checkbox " name= "a1 " value= "11 ">
<input type= "checkbox " name= "a2 " value= "11 ">
<input type= "checkbox " name= "a3 " value= "11 ">
<input type= "checkbox " name= "a4 " value= "11 ">
<input type= "checkbox " name= "a15 " value= "11 ">
</form>
<script>
f = document.forms[0];
for(c=0; c <f.length; c++) alert(f.elements[c].value);
</script>
