Adding array element into the preview box

[drianautz]

Hello, actually how to add array content inside the preview box, i mean if i have the attribute like this, i try it >
HTML at a data

data-size1="Small"
data-size2="Medium"

data-price1="$ 23"
data-price2="$ 49"

On // update preview´s content
var $itemEl = this.$item.children( 'a' ),
eldata = {

size1 : $itemEl.data( 'size1' ),
price1 : $itemEl.data( 'price1' ),
size2 : $itemEl.data( 'size2' ),
price2 : $itemEl.data( 'price2' )

On html push

this.$size1.html( eldata.size1 );
this.$price1.html( eldata.price1 );
this.$size2.html( eldata.size2 );
this.$price2.html( eldata.price2 );

On Preview.prototype =
create : function()

this.$size1 = $( '

' );
this.$price1 = $( '

' );
this.$info1 = $( '

' ).append( this.$size1, this.$price1 );
this.$addtocart1 = $( '' );
this.$item1 = $( '

' ).append( this.$info1, this.$addtocart1 );
this.$variant1 = $( '

' ).append( this.$item1 );

this.$size2 = $( '

' );
this.$price2 = $( '

' );
this.$info2 = $( '

' ).append( this.$size2, this.$price2 );
this.$addtocart2 = $( '' );
this.$item2 = $( '

' ).append( this.$info2, this.$addtocart2 );
this.$variant2 = $( '

' ).append( this.$item2 );

this.$clearfix = $( '

' ).append( this.$variant1, this.$variant2 );

but it's only limit for 2 items, actually how to add an array into this,

Thanks
