javascript and []

<form name=f>
<input type=text name="apple[]" value=1>
</form>

<script>
document.f.appl e[].value=2
</script>

///////////////////////////
this generates an script error in IE
because of apple[]
so how do I get around the error?
(must use "apple[]" for server cgi)

thanks in advance :)

document.getEle mentsByName("ap ple[]") //returns an object array

Not really. I assume that you are using php, which also supports an
always_populate _raw_post_data directive.

With this directive enbled, you can simply use normal names and still use
arrays:

<form method="post" action="...">
<input type="checkbox" name="fruit" value="apple" /> Apple<br />
<input type="checkbox" name="fruit" value="banana" /> Banana<br />
<input type="checkbox" name="fruit" value="pear" /> Pear<br />
<input type="submit" />
</form>
.....
<?
if (!isset($HTTP_R AW_POST_DATA) ||
!strstr($HTTP_R AW_POST_DATA, 'fruit=')) {
print "Please select some fruits";
} else {
parse_str(
str_replace(
"fruit=",
"fruit[]=",
$HTTP_RAW_POST_ DATA
),
$fruits
);
print "Selected fruits:<br />";
foreach ($fruits['fruit'] as $fruit) {
print "$fruit<br />";
}
}
?>

document.forms['yourForm'].elements['apple[]'].value = 2;

Now you don't need to remember form input indices or use a
browser that is completely W3C compliant.

[snip]
That would depend on if the compilation of your version of PHP
supports ALWAYS_POPULATE _RAW_POST_DATA. . you're safer using an array
construct, sorry.

<input type="checkbox" name="fruit[]" value="apple">A pple

in Javascript you would call this element cross-browser:
document.forms['myForm'].elements['fruit[]']
