Fraction number in Javascript

I'm working on a JavaScript project in which I need to display an array of numbers. This numbers can be integers or fractions. I need to display the fraction in the classic way, I mean, the top number, below a line and below the other number, as shown in this example:

http://jsfiddle.net/xW7d8/

The thing is that the array that I was talking about is the one that contains the numbers, and using Jquery I change the text of a div so I display the numbers, just like this:

97,30,58,53,42,60,77,11

69/90,10/32,74/74,9/54,69/2,17/86,62/72,55/85

First thing that I do is to fill the array, save the numbers to a string, and then, change the text of the div. Below is what I do in code:

var array = fillArray();//this fill an array of numbers, integers or fractions
var stringArray;//will contains the numbers of the array
for(var i=0;i<array.length;i++)
{
  stringArray+= array[i];
}
$("#num1").text(stringArray);

In this way, I cannot put a div ID to each number, if I try to do this its not interpreted as HTML, what I take is the text of the HTML tag itself, for example, for the number 1/2 if I try to do:

<span class="fraction">1/2</span>

I literally get the span class, it is not read as HTML code.

I tried also to generate the format for the fraction in the JavaScript code itself doing this:

var number = x + "\n" + "-" + "\n" + y;

This do not work, it don't recognize the "\n", neither "\r", etc (if I try with < br/ > is written literally)

Is there some way to get the fraction numbers the way I want? Probably I will need to generate the number in this format in the JavaScript itself without the help of the HTML tags.

Try this with the string containing the tags. It should begin with a tag, though:

$("#num1").html(stringArray);

But since your fiddle rewrites the div with the fraction class you probably just want to generate the whole html of the fractions yourself. <span class="top">1</span><span class="bottom">2</span> instead of doing the <span class='fraction'>1/2</span> and then running the code to convert.

Sounds to me like you want to use JQuery's html() function instead of text()

$("#num1").html(stringArray);

Does this help?
