It sounds strange that value="2" would be the number of points.
Usually, a value would be used to indicate a unique answer for a
question. Usually, 1, 2, 3, 4 if you have 4 possible answers for one
question. I would suggest using the ID or CLASS attribute, or
Javascript objects to store that type of info.
Do you have another attribute that determines what the "correct"
answer is for a question? Or is there no correct answer? Just a
selection?
Otherwise, to do what you want to do, you can do something like
(untested):
(You might have to double-check this, but it's an idea.)
var total = 0;
$("#submit_btn").click(function() {
$("input[name^='question_']).each(function() {
var answer_value = $(':checked', this).val();
if (answer_value)
total += parseInt(answer_value);
});
});
Question 1:
<input type="radio" name="question_1" value="1"> Answer 1
<input type="radio" name="question_1" value="2"> Answer 2
<input type="radio" name="question_1" value="3"> Answer 3
<input type="radio" name="question_1" value="4"> Answer 4
Question 2:
<input type="radio" name="question_2" value="1"> Answer 1
<input type="radio" name="question_2" value="2"> Answer 2
<input type="radio" name="question_2" value="3"> Answer 3
<input type="radio" name="question_2" value="4"> Answer 4
<input type="button" id="submit_btn" value="Submit">
