Coding to Display Result

Hi mubasher99,
as you can imagine, HD Quiz has changed a lot in the past 5 years, including a major rewrite 7 months ago. The following code should replace everything I previously gave you.

NOTES:

• Requires you to have full marking enabled (“Show correct answers on completion”).
• Not compatible with all question types (Example: Text based answers will always show as being answered since marking fills in the values automatically)
• Will not work with an upcoming new feature for Weighted Answers.
• Feel free to edit the STEP 3. Print the result onto the page part of the code to modify the HTML output however you feel works best for you.
• Based on the code you referenced, it looks like you only wanted this data to print if the user does not pass the quiz?

function hdq_before_mubasher99($quizID)
{
?>
	<script>
		function hdq_custom_submit() {
			// STEP 1. Figure out how many questions were not answered
			let unanswered = 0;
			const questions = document.getElementsByClassName("hdq_question");
			for (let i = 0; i < questions.length; i++) {
				if (parseInt(questions[i].getAttribute("data-weight")) == 0) {
					continue; // make sure this is a markable question
				}

				const answeredWrong = questions[i].getElementsByClassName("hdq_wrong");
				const answeredCorrect = questions[i].getElementsByClassName("hdq_correct");
				if (answeredWrong.length === 0) {
					if (answeredCorrect.length === 0) {
						unanswered = unanswered + 1;
					}
				}
			}

			// STEP 2. Calculate each paremeter
			const correct = HDQ.VARS.hdq_score[0]; // answers that were correct
			const incorrect = HDQ.VARS.hdq_score[1] - HDQ.VARS.hdq_score[0]; // total questions - correct answers
			let p = (parseFloat(HDQ.VARS.hdq_score[0]) / parseFloat(HDQ.VARS.hdq_score[1])) * 100;
			p = p.toFixed(2);
			console.log("Correct: " + correct)
			console.log("Incorrect:" + incorrect)
			console.log("Unanswered: " + unanswered)

			// STEP 3. Print the result onto the page
			const html = <p class="Online-Test-result-sheet"><br>    Correct Answers: <strong>${correct}</strong><br/><br>    Incorrect Answers: <strong>${incorrect}</strong><br/><br>    Unanswered Questions: <strong>${unanswered}</strong><br/><br>    Percentage: <strong>${p}%</strong><br></p>;
			let results_section = document.getElementsByClassName("hdq_result_fail")[0];
			results_section.insertAdjacentHTML("beforebegin", html);

			return JSON.stringify('{}'); // expects a JSON string to be returned
		}
	</script>
