Validation with js of two dimensional array

Dec 20th, 2006

In html i have some question, and the answers are radio buttons ...
the names of variables in html are array ... like question[1], question[2] ... etc.
and every question has multiple value, depending of the answer.

[html]<form action="thx.php" method=POST name=form onSubmit="return check(this)">[/html]

In javascript i have to determinate if the question is answered, if it is not then return false ...

Help with Code Tags

(Toggle Plain Text)

function check(form) {


    a=0;
    for (i=0;i<form.question[1].length;i++){
    if (form.question[1][i].checked===true)  {a=1;}
    }
    if (a==0) {
    alert("question[1] no.1: You didn't answer the question");
    return false;
    }
}

Everything work fine until i changed my variables into arrays.
What is wrong now?
How javascript handle two dimensional array?

pls help

O_o maybe javascript doesn't do what you think it does... or maybe that's too incomplete a code snippet to see what your trying to do. forms.question[1] doesn't look like a DOM object reference.. and it wont neccessarily relate to any input element(s) on your HTML page...

what is the HTML code you are using?

If it only works in Internet Explorer; it doesn't work.
