Enter javascript: in the status line to see the console with any error
messages. Trying to click Submit results in:
JavaScript Error: document.quiz.T1 is not a function
Indeed:
if (document.quiz.T1(0).checked)
T1 is an array of inputs. You read an input from the array using the
array[index] syntax, not function(arguments). I'm amazed this ever worked
in any browser. Changing to square brackets fixes it.
BTW you could perhaps change that long script to something like:
var answers= 'bcabc';
function Evaluate() {
var els= document.forms['quiz'].elements;
var el, sel, ans, mark;
for (var i= 0; i<answers.length; i++) {
el= els['T'+(i+1)];
sel= '';
for (var j= 0; j<el.length; j++)
if (el[j].checked) sel='abcdef'.charAt(j);
if (sel!='') {
ans= answers.charAt(i);
mark= (sel==ans) ? 'check' : 'x';
document.images['none'+(i+1)].src= ans+'-'+mark+'.gif';
} }
}
which would allow you to add questions and answers more easily.
