Ive found a fancy shopping cart tutorital which gives a decent break down of how to do it step by step, i followed pretty well until i got up to a line of code which i dont under stand

(function($){	
	    $.fn.smartCart = function(options) {  	
        var options = $.extend({}, $.fn.smartCart.defaults, options);
                
        return this.each(function() {
        	
                var obj = $(this);
                // retrive all products
                var url = "shoppingItems.json";//essentially new products
                var products = $("input[type=hidden]",obj);//what is this for
}); 
    };
})( jQuery );

The code which im not sure about is var products =$("input[type = hidden]",obj); From what i understand, this is a multiple selector which is being put into products, which i cant see a use of. obj is simply a empty div tag in whihc i call from my html

<script type="text/javascript">
   
    $(document).ready(function(){
    	// Call Smart Cart instead of features maybe something more higher up to include more features    	
  		$('#featured').smartCart();
		});
</script>

the <input> is comprised of a list of shopping items which i have now moved into json file(so i will soon not be needing to use input rather my json url)
Essentially i would like to know if var products is a multiple selector, and if so why. understanding this will make the transition to making it json rather than from html easier.

cf. http://api.jquery.com/jQuery/. search for hidden form fields in obj. (similar to document.getElementById("x").getElementsByTagName("y"))

[skyerz]

so find elements within

<input>

that are also inside obj??? in that case by taking obj out it shouldnt really effect anything more just the search results ?

and what if you have hidden input fields elsewhere in your page that do not belong to the smartCart?

PS. obj == $("#featured")
