I'm creating a mini quiz, if the answer is correct the background will be green, if is wrong will be red

}
}
}
}
var radio1 = document.getElementByName("0").value;
if (answers[0] == radio1) {
document.getElementById("0").style.backgroundColor="#00FF00";
} else {
document.getElementById("0").style.backgroundColor="#e83f3f";
}
if(score > 3) {
document.getElementById("rezultati").innerHTML = "Congratulation!";
} else {
document.getElementById("rezultati").innerHTML = "Try again!";
}
form.percentage.value = score;
form.solutions.value = correctAnswers;
}
// End -->
</script>
I get always red background and if the answer is correct, maybe document.getElementByName("0").value is not getting a number to make true the condition
var radio1 = document.getElementByName("0").value;
if (answers[0] == radio1) {
document.getElementById("0").style.backgroundColor="#00FF00";
} else {
document.getElementById("0").style.backgroundColor="#e83f3f";
}
var radio1 = document.getElementByName("0").value;
if (answers[0] == radio1) {
Probably your error is in this line of code, the id="0" is a div and you are trying to get the value of it, this might result into undefined and the value answer[0] is 1, thus 1 is not equal to radio1, thus it is always getting into the else block.

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
Please study the code and see if you understand. I can add more comments if needed
var answers = ["doesn't like","don't come","come"];
var rads, quiz; // need to be set after load
window.addEventListener("load",function() { // when page loads
quiz = document.getElementById("quiz");
rads = quiz.querySelectorAll("input[type=radio]"); // all radios in the quiz
document.getElementById("scoreButton").addEventListener("click",function(e) { // on click of scoreme
var score = 0;
for (var i=0;i<rads.length;i++) { // loop over all radios in the form
var rad = rads[i];
var idx = rad.name.substring(1)-1; //remove the q from the name - JS arrays start at 0
var checked = rad.checked;
var correct = rad.value==answers[idx];
if (correct) {
rad.closest("label").classList.toggle("correct");
if (checked) score +=3;
}
else if (checked) {
score--;
rad.closest("label").classList.toggle("error")
}
}
var scoreper = Math.round(score * 100 / rads.length);
document.querySelector("#percentage").innerHTML = scoreper + "%";
quiz.mark.value = score;

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
window.addEventListener("load", function() { // when page loads
quiz = document.getElementById("quiz");
rads = quiz.querySelectorAll("input[type=radio]"); // all radios in the quiz
document.getElementById("scoreButton").addEventListener("click", function(e) { // on submit
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;

This is just a readonly. See the docs:
hidden
Is a Boolean attribute indicates that the element is not yet, or is no longer, relevant. For example, it can be used to hide elements of the page that can't be used until the login process has been completed. The browser won't render such elements. This attribute must not be used to hide content that could legitimately be shown.
What you must really do is:
document.getElementById("classic").style.display = 'none';
document.getElementById("quizr").style.display = 'block';

return false;
}
answer1 = (form.q1.value);
a=Math.floor(answer1);
document.getElementById("result").innerHTML= "The selected values are "+"</br>"+answer1;
}
you should declare a answer variable .and you should access "q1" elements by giving index since you have 3 "q1" elements .basically form.q1 is a object NodeList .you can't get value from object NodeList.so actually in your case you should add brake to for loop and find the clicked radio button index .
you should use
answer1 = form.q1[i].value;
instead of
answer1 = form.q1.value;
explain
form.q1 is a object NodeList so
form.q1.value --> undefined since object NodeList/collection has no property "value"
and
form.q1[0] --> HTMLInputElement so
form.q1[0].value --> is not undefined
fixed code .WORKING DEMO http://jsfiddle.net/madhawa11111/3rywkdvf/
function hp(form) {
var i;
var answer;
var count1 = 0,count2 = 0,count3 = 0,count4 = 0,count5 = 0,count6 = 0,count7 = 0,count8 = 0,count9 = 0,count10 = 0, a;
for (i = 0; i < 3; i++) {
if (form.q1[i].checked === true) {
count1++;
break;
}
}
if (count1 !== 1) {
alert("Please Answer 1st Question");
return false;
}
answer1 = form.q1[i].value; //error was here .
a = Math.floor(answer1);
document.getElementById("result").innerHTML = "The selected values are " + "</br>" + answer1;
}
if it worked in google chorm that's because browsers ignore some errors.
I am basically trying to have a word (page 2) be clickable and act as a link to display different div content. When they select option 2, then click the next button, they should be able to click "Page 2" test and cause that to display the id="test1" (Choice 1, Page 1) content. I have tried a few variables but haven't been able to get any to work. The best I could do is get it to take you back to the choice options, but I'd like to eliminate any users error and just go straight to the first page of the choice they should have made.
Any help would be grateful. And sorry, JQuery is not an option.

Okay, I think this is what you want, it may be a bit big, but it's a full solution for your problem, I guess. Mainly, you have some pages, the user may choose, which page to see first, but then you force the user to see all next pages one by one till the end. At least, it's what I did here.
You may add as much text pieces (pages) as you like in textContent array, just check that you have a corresponding number of radio buttons.

I think this is what you may be looking for
function showPage(id)
{
document.getElementById(id).style.display = 'block';
}
Choice 1
Ok, so here I've added consequent steps, that can be split into some categories (here: 3), if you select a step from some category, you will just read it. Hope that helps ;)
