Firefox thinks <fieldset> is a form element; Chrome doesn't

In my JavaScript program, I get values from a form through its elements and then print them in order, in an alert. This works fine in Firefox, but in Chrome the order is wacky and it ends with the "Submit" button.

I tried getting rid of the fieldset and adjusting the numbers, and it worked, but I liked the fieldset! Also, I can't just make an array and iterate through it because the fields are tab-order adjusted and I want to print them accordingly. Any suggestions?

Upon trying to validate I found that I do indeed need the fieldset for XHTML Strict. I've been storing the elements in an array, like so:

var $ 开发者_StackOverflow中文版= function (id) { return document.getElementById(id); }

function check() {
var x = $("myForm");

var user = new Array();
user[0] = x.elements[0].value;  
user[1] = x.elements[2].value;  
user[2] = x.elements[4].value;  
user[3] = x.elements[1].value;  
user[4] = x.elements[3].value;  
user[5] = x.elements[5].value;  

And then checking them using another couple of arrays and displaying the results in a pop-up:

var answers = new Array();
answers[0] = "sample1";
answers[1] = "sample2";
answers[2] = "sample3";
answers[3] = "sample4";
answers[4] = "sample5";
answers[5] = "sample6";

var display = new Array();
for (var i=0;i<6;i++) {
    if (user[i] == "") {
        display[i] = "You entered nothing.";
        }
    else if (user[i] == answers[i]) {
        display[i] = "Correct!";
        }
    else {
        display[i] = "Wrong. The correct answer is \"" + answers[i] + "\".";
        }
    }
alert(display[0] + "\n" + display[1] + "\n" + display[2] + "\n" + display[3] + "\n" + display[4] + "\n" + display[5]);
}

I think you'll be better off using IDs:

<form ...>
  <input ... id="q0" />
  <input ... id="q1" />
  <input ... id="q2" />
</form>

So you can write this JavaScript code:

var answers = new Array();
answers[0] = "sample1";
answers[1] = "sample2";
answers[2] = "sample3";
answers[3] = "sample4";
answers[4] = "sample5";
answers[5] = "sample6";

var display = new Array();
for (var i=0;i<6;i++) {
  var user = $('q' + i).value;
  if (user == "")
    display[i] = "You entered nothing.";
  else if (user == answers[i])
    display[i] = "Correct!";
  else
    display[i] = "Wrong. The correct answer is \"" + answers[i] + "\".";
}
alert(display[0] + "\n" + display[1] + "\n" + display[2] + "\n" + display[3] + "\n" + display[4] + "\n" + display[5]);

Your code can receive a lot of improvement, too:

var answers = [ "sample1", "sample2", "sample3", "sample4", "sample5", "sample6" ];

var display = new Array();
for (var i=0;i<6;i++) {
  var user = $('q' + i).value;
  if (user == "")
    display.push( "You entered nothing." );
  else if (user == answers[i])
    display.push( "Correct!" );
  else
    display.push ( "Wrong. The correct answer is \"" + answers[i] + "\"." );
}
alert(display.join('\n'));
