[Solved] exam with timer in javascript [closed]

by


you could store the question and answers in a multidimensional array like follows

// [question number, answer, question]
var qanda =[ 
[1,15,"Add 11 + 4"],
[2,7,"Add 4 + 3"],
[3,7,"Subtract 9 - 2"]
];


function getQuestion(n){


document.getElementById("disp_question").innerHTML = qanda[n][2];

document.getElementById("intp_div").style.display = "block";

}

function checkAnswer(n){


if(document.getElementById("intp_answer").value != undefined){

if(document.getElementById("intp_answer").value == qanda[n][1]){

alert("correct")

    }else{
   alert("incorrect")
    }

}
}

And you could add this below your retry button

<div id="intp_div" style="display:none">
<h3 id="disp_question"></h3><input id="intp_answer" type="text" value=""><input type="button" value="Submit Answer" onclick="checkAnswer(2)" />
</div>`

this it just to hepl you get on your way Note:

onclick="checkAnswer(2)" the “2” is the question your refferencing from the q and a array
