Javascript & PHP conflict in multiple select f

[Anon]

I have a form with multiple select field which I validate with javascript before posting. PHP likes to have

<select name=test[] multiple>

kind of declaration to store the vars in an array. On the other hand, javascript does not allow [] in the name of the component, therefore I cannot access the the component such as

document.forms.myform.test[].options.length

for example.

There must be a way to access the posted vars even if the var names are the same. In other words I want to see the http request string "?test=1;test=2;test=3" so that I myself can parse it and I can keep the name of the component name free of []s.

Thanks,

You cannot access the component as
document.myform.test[].options.length
but you can as:
document.myform.elements[index].options.length
where index is the order of the form element (the select box, in this case) as it appears in html source code.

I had the same problem and I solved this way.
Hope it helps.

You can also do (bit more robust):

document.myform.elements[\'test[]\'].options.length

I didnt put the slashes before the quote mark by the way.
