how would i build a multidimensional array? would it be:
i've figured that out so far.PHP Code:var rinksAndPriceArray = new Array();
rinksAndPriceArray[0] = new Array();
rinksAndPriceArray[1] = new Array();
now, i want to be able to access a part of one of the arrays based on a variable that is passed into the function
the variable i'll send in will be the first part of the array ex: rinksAndPriceArray[0][0] and i'll want to return the rinksAndPriceArray[0][1] value.
any ideas?

Yes, you could use a multidimensional array - and then try to remember if myArray[0][1] or myArray[1][0] contains the value you are looking for...
I vote for this "object oriented" approach:
Code:<html> <head> <script language="javascript"> function Item(id, name, price) { this.id = id; this.name = name; this.price = price; } function findItem(arr, id) { for(var i = 0; i < arr.length; i++) { if(arr[i].id == id) { return arr[i]; } } return null; } var arrItems = new Array(); arrItems[0] = new Item(123, 'A thing', '$99'); arrItems[1] = new Item(456, 'Another thing', '$55'); arrItems[2] = new Item(789, 'Stuff', '$1'); var id = 456; var item = findItem(arrItems, id); if(item) { document.write('The name of the item with id ' + id + ' is ' + item.name + ' and the price is ' + item.price); } else { document.write('There is no item with id ' + id); } </script> </head> <body> </body> </html>
