I hope you enjoy this video tutorial so let’s start with a basic HTML structure for the Quiz App Using Javascript.

<script src="app.js"></script>

</html>

HTML Structure :

We’ll add a few links to the external javascript and CSS files inside the header section before adding structure to our website. Additionally, since we utilised Bootstrap for this project, we need to include certain Bootstrap links in it.

Structure:

  •  Now using the div tag we will add the container of our quiz app .
  • Using the div tag we will add two title one is for javascript quiz and another is for counting the total  number of question inside our quiz app.
  • After that, we will add the structure of a form, such as one with a question, using the bootstrap predefined classes, and we will add the 4 alternatives to each question using the radio type input.

  • Next, we will construct two buttons with the button tag: one for going to the previous question and one for the following question.

However, some of the default styling is derived from the bootstrap predefined CSS. We have just contributed a few extra stylings to our quiz app’s CSS. The individual elements of our quiz app will get some extra padding and margin here in our css file using the class selector, making it seem nicer.

$('#previous').click(function (e) {

if (selectedopt) {

}
jsq.changeQuestion(-1);
});

First, we built an object in our Javascript, and then we added a question with a certain ID number to that object. We have built 25 questions in total and placed them within our object. The user will receive the quiz task’s outcome at the end of the quiz by utilising the conditional statements to verify, as the user clicks on any of the alternatives, if and else statements, whether the answer they choose matches the proper response.
