JavaScript Array Help

Can somebody have a look at this bit of code.

HTML Code:

<html>
<script>

        var studentNum = new Array(2)
        var students = new Array(2)
        var eMail = new Array(2)
        
        for(var i = 0; i < studentNum.length; i++)
        {
            studentNum[i] = eval(prompt("Enter Student Number: " + i));
            students[i]= prompt("Enter Student Name: " + i)
            eMail[i] = prompt("Enter Students E-Mail: " + i)
        }

        var searchingFor = eval(prompt("Enter Students Number "));
        var j = 0;
        for(j in studentNum)
        {
            if (studentNum[j] == searchingFor)
            {
                alert("Student Number: " + searchingFor + "\nName: " +
                students + "\nE-Mail: " + eMail);
                break;
            }
        }    
</script>
</html>

Can anyone spot the problem and help with a solution please.

What I've been trying to do is search for a single value in an array of strings, yet when it outputs as seen below more than one value is outputted in the Name and E-Mail.

This line;

HTML Code:

students + "\nE-Mail: " + eMail);

Should be this;

HTML Code:

students[j] + "\nE-Mail: " + eMail[j]);
