You can use javascript with this naming convention, just not the way you're
probably doing it. Here's a working example:
<html>
<head>
<title></title>
</head>
<body>
<script language="javascript" type="text/javascript">
function getValue(field)
{
var form = document.testform;
var temp = form[field].value;
return(temp);
}
function getArrayValue(field, index)
{
var form = document.testform;
var temp = new Array();
var type = form.type;
for (i=0; i<form.length; i++)
{
if (form[i].name == field)
{
temp.push(form[i].value);
}
}
if (temp.length >= index)
{
return(temp[index]);
}
else
{
return(false);
}
}
function test()
{
test_0 = getValue("test[0]");
test_1 = getValue("test[1]");
test_2 = getValue("test[2]");
test2_0 = getArrayValue("test2[]", 0);
test2_1 = getArrayValue("test2[]", 1);
alert(
"test_0 = " + test_0 + "\n" +
"test_1 = " + test_1 + "\n" +
"test_2 = " + test_2 + "\n" +
"test2_0 = " + test2_0 + "\n" +
"test2_1 = " + test2_1 + "\n"
);
}
</script>
<form name="testform">
<table>
<tr>
<td>test[0]</td>
<td><input type="text" name="test[0]" value="this is test
0"></td>
</tr>
<tr>
<td>test[1]</td>
<td><input type="text" name="test[1]" value="this is test
1"></td>
</tr>
<tr>
<td>test[2]</td>
<td><input type="text" name="test[2]" value="this is test
2"></td>
</tr>
<tr>
<td>test2[]</td>
<td><input type="text" name="test2[]" value="this is test2
0"></td>
</tr>
<tr>
<td>test2[]</td>
<td><input type="text" name="test2[]" value="this is test2
1"></td>
</tr>
<tr>
<td colspan="2"><input type="button" value="test"
onclick="javascript:test();"></td>
</tr>
</table>
</form>
</body>
</html>
Hope this helps.
