예:

<FORM NAME='myform' ....>
...
<INPUT TYPE='checkbox' NAME='_check[name]' VALUE=1 CHECKED>
<INPUT TYPE='checkbox' NAME='_check[addr]' VALUE=1>
<INPUT TYPE='checkbox' NAME='_check[email]' VALUE=1>
...
</FORM>


<SCRIPT ...>
...
var form = document.myform; // form 정의
var check_name_value = form.elements["_check[name]"].value; // 값
var check_name_check = form.elements["_check[name]"].checked; // checked
유무

// 이와 같이 elements["폼변수이름"]
 을 사용

</SCRIPT>


<INPUT TYPE='text' NAME='_address[]' VALUE='011'>
<INPUT TYPE='text' NAME='_address[]' VALUE='1234'>
<INPUT TYPE='text' NAME='_address[]' VALUE='5678'>

address[0].value ==> elements["_address[]"][0].value
address[1].value ==> elements["_address[]"][1].value
address[2].value ==> elements["_address[]"][2].value
