I am trying to write a quiz app.Below is the source code.Currently it is working like as below :
- On Click start Quiz,first questions shows up.
- User selects correct option and it moves to say question number 3.
- if User selects wrong option,it moves to another question say question number 4.
and so on...
Please check link http://plnkr.co/edit/sYG9jjX0JATbQhJ1hNf6
What I want to achieve is as below :
- On Click start Quiz,first questions shows up.
- User selects correct option and it moves to say question number 3. Now at this time,there are two questions on the screen(1st and 3rd).
- Now say user changed the option in 1st question and selected any other answer,3rd question should go off and another question(say question number 4) should be displayed.
- If user has already browsed through 3-4 questions and then changes option of say first question then only next possible question should be displayed and not all 3-4 questions.
Please find below code :
