Query regarding checkboxes in JavaScript

I found this code for select/unselect all checkboxes. It works. In each input has a name=list, I want that this code works with the name=list[]

When I change this option in the button in JavaScript appears error:

<input type=button value="Check All" onClick="this.value=check(this.form.list[])">

This is the original code:

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var checkflag = "false";
function check(field) {
if (checkflag == "false") {
for (i = 0; i < field.length; i++) {
field[i].checked = true;}
checkflag = "true";
return "Uncheck All"; }
else {
for (i = 0; i < field.length; i++) {
field[i].checked = false; }
checkflag = "false";
return "Check All"; }
}
// End -->
</script>

<center>
<form name=myform action="" method=post>
<table>
<tr><td>

<input type=checkbox name=list value="2">JavaScript<br>
<input type=checkbox name=list value="3">ASP<br>
<input type=checkbox name=list value="4">HTML<br>
<input type=checkbox name=list value="5">SQL<br>
<br>
<input type=button value="Check All" onClick="this.value=check(this.form.list)">
</td></tr>
</table>
</form>
</center>
