Jquery - How to pass multiple variable through class name?

I want to create a generic/scalable class that is able to accept none or multiple variables and process it. I want to learn how to check which field is present, number of field passed and do something with it. The 'fruitstall' class can accept 0 or multiple number of fruits variable.

HTML:

<div class="fruitstall(apple,orange)"></div>

Script:

$('.fruitstall').click(function(event){
   if (get first variable value and check if it is an apple) {
      //Show apple image 
   } elseif (get the next variable value and check if it is an orange) {
      //Show orange image
   }
   alert('Number of fruit chosen are ' + (count number of variable passed to class) + ' ; ' fruit(index0) + fruit(index1));
});

Pardon my fruit stall example, I thought it would be interesting to ask question in a more lively method. :)

Thank you very much.

I don't know if that could work, but if you prepare you class String as a JSON one, you could use eval() to get an object from which you could enumerate arguments

 function prepareAsJSON(className){
        var JSON = "{list:function" + className + "{return arguments}}"
        return JSON
 }

 var className = $("div").attr('class');
 var st = prepareAsJSON(className);
 var obj = eval(st)
 obj.list() //should return arguments as an array

I would never do that in production code, but that's pretty funny

Another way might be to use HTML5 data attributes:

<div class="fruitstall" data-fruits="apple,orange"></div>

Then your JS code could go:

var fruits = $(this).data('fruits').split(',');

which would get an array of all the fruits for the stall.

You can have multiple classes assigned:

<div class="apple orange" id="divId"></div>

And then do a split on them like so:

var classList =$('#divId').attr('class').split(/\s+/);
$.each( classList, function(index, item){
    if (item=='someClass') {
       //do something
    }
});
