Javascript quiz timer

Hi I am making a quiz using javascript but am struggling to put in a functioning countdown timer. This may be a simple question but how can I make it so that once the timer reaches zero it'll submit the quiz and tell the user times up? I have tried a few different ways but to no avail. Any help is appreciated.
My code for the countdown timer:
<script>
var total_seconds = 30*1;
var c_minutes = parseInt(total_seconds/60);
var c_seconds = parseInt(total_seconds%60);
function CheckTime(){
document.getElementById("quiz-time-left").innerHTML
= 'Time Left: ' + c_minutes + ' minutes ' + c_seconds + ' seconds ' ;
if(total_seconds <=0){
setTimeout('document.quiz.submit()',1);
} else {
total_seconds = total_seconds -1;
c_minutes = parseInt(total_seconds/60);
c_seconds = parseInt(total_seconds%60);
setTimeout("CheckTime()",1000);
}}
setTimeout("CheckTime()",1000);
</script>
My code for the quiz:
<form name="form" onsubmit="return score()">
<h3>1. How many yellow cards equal a red card in football?</h3>
<input type="radio" name="q1" value="a">a. 1<br>
<input type="radio" name="q1" value="b">b. 2<br>

for (var i = 0; i < total; i++)
{
if (questions[i] == answers[i]) {
points = points + 1; //Increment the score by 2 for every correct answer given
}
}
//CSS for questions
var q = document.getElementById("p");
q.style.fontSize = "40px";
q.style.textAlign = "center";
q.innerHTML = "You got " + points + " out of " + total;
return false;
}
</script>

Your html were divided into several forms, you only need one. You were missing the quiz time left div in your example so i added it to the top.
As a little extra touch i disabled the input when the timer runs out.
var total_seconds = 30 * 1;
var c_minutes = parseInt(total_seconds / 60);
var c_seconds = parseInt(total_seconds % 60);
var timer;
function CheckTime() {
document.getElementById("quiz-time-left").innerHTML = 'Time Left: ' + c_minutes + ' minutes ' + c_seconds + ' seconds ';
if (total_seconds <= 0) {
score();
} else {
total_seconds = total_seconds - 1;
c_minutes = parseInt(total_seconds / 60);
c_seconds = parseInt(total_seconds % 60);
timer = setTimeout(CheckTime, 1000);
}
}
timer = setTimeout(CheckTime, 1000);
function score() {
// stop timer
clearInterval(timer);
//Referencing the value of the questions
var q1 = document.forms.form.q1.value;
var q2 = document.forms.form.q2.value;
var q3 = document.forms.form.q3.value;
// disable form
var elements = document.getElementById("questions").elements;
for (var i = 0, len = elements.length; i < len; ++i) {
elements[i].disabled = true;
}

change label text of all radio button in quiz as red and green

Below is the code of a sample radio button quiz where multiple radio buttons are provided. Correct answers and wrong answers are defined in the code. User may check any answer or keep all blank. If user checks any radio button and finally clicks "Grade Me" button, label text of radio button of any wrong answers checked by the user shall appear as red and at the same time correct answer of that particular question shall appear in green (This will help the user know which question he answered wrong and what is its correct answer). I have tried several steps and searched many forums and failed. I think it will be really simple.
Example:
var numQues = 3;
var numChoi = 3;
var answers = new Array(3);
answers[0] = "doesn't like";
answers[1] = "don't come";
answers[2] = "come";
var wrong = new Array(3);
wrong[0] = "don't like";
wrong[1] = "doesn't come";
wrong[2] = "comes";
var wrong1 = new Array(3);
wrong1[0] = "doesn't likes";
wrong1[1] = "doesn't comes";
wrong1[2] = "coming";
function getScore(form) {
var score = 0;
var currElt;
var currSelection;
for (i = 0; i < numQues; i++) {
currElt = i * numChoi;
answered = false;
for (j = 0; j < numChoi; j++) {
currSelection = form.elements[currElt + j];
if (currSelection.checked) {
answered = true;
if (currSelection.value == answers[i]) {
score += 3;
break;
}
if (currSelection.value == wrong[i]) {
score -= 1;
break;
}
if (currSelection.value == wrong1[i]) {
score -= 1;
break;
}
}
}
}
var scoreper = Math.round(score * 100 / 9);
form.percentage.value = scoreper + "%";
form.mark.value = score;
}

Here is a rewrite of your code.
I fixed the illegal HTML and used best practices with event listeners, querySelectors and CSS

In your getScore function, when you find out that a certain element has a correct answer selected (whichever var is the label - unless you are using a custom radio button which I would recommend since changing the background of the label element would simply highlight the words), you can give it a new class using JS.
currSelection.classList.add("correct");
or
currSelection.classList.add("incorrect");
Then in your CSS file you can have rules saying
.correct { background: green !important; }
.incorrect { background: red !important; }

WoW!....Close....Thanks for support. But still all the wrong answers are showing red color. This will let the user know which question he answered wrong. That part is Okay. But once the wrong answers are marked with red(I mean only the wrongly selected radio button choice texts and not the entire question and answer choices
the correct answer of that wrong attempt to be shown in green to enlighten the user. And the sad part is that I again failed with the CSS thing. I wanted to create a quiz in blog and added custom CSS with conditional tag in html of blogger post.....Not Working. However, I will add the modified code here so that you get a clear picture if I am doing rightly as you said.(How and where to add the CSS rules inside this code(if that is what you mean))
var answers = ["doesn't like", "don't come", "come"];
var rads, quiz; // need to be set after load

quiz = document.getElementById("quiz");
rads = quiz.querySelectorAll("input[type=radio]"); // all radios in the quiz

var score = 0;
var checked = quiz.querySelectorAll("input[type=radio]:checked"); // all checked radios
for (var i = 0; i < checked.length; i++) { // loop over all checked radios in the form
var idx = checked[i].name.substring(1) - 1; //remove the q from the name - JS arrays start at 0
var correct = checked[i].value == answers[idx];
checked[i].closest("p").classList.toggle("error", !correct)
checked[i].closest("p").classList.toggle("correct", correct)
score += correct ? 3 : -1; // this is called a ternary
}
var scoreper = Math.round(score * 100 / rads.length);
document.querySelector("#percentage").innerHTML = scoreper + "%";
quiz.mark.value = score;

You have two options instead of using an alert ...
1) Create a layered popup that pops up in front of all your page content (you could darken the BG as well like most modals do). This would allow you to pop the message up in the same page and not require the user to open another window.
2) Your other option would be to popup a new window and use javascript to write the information to that window. See the following link for more information on this: http://www.electrictoolbox.com/write-content-dynamic-javascript-popup/
I personally would go with the first because it guarantees that it will work even if the user has a popup blocker.
