Array - for loop

Jul 23 '05, 10:09 AM

Hi is there any other way of writing this function, I am just wondering if
there is another way of reading through the array like using a for loop or
something. Can you do this using a for loop?

Thanks

var base = 799;
var RAM = [ 0, 70, 150, 280 ];
var HD = [ 0, 30, 70 ];
var OS = [ 0, 70, 20, 90 ];
function calcPrice() {

var price = base;
var form = document.forms[ 'myForm' ];

price += RAM[ form.elements[ 'RAM' ].selectedIndex ];
price += HD[ form.elements[ 'HardDrive' ].selectedIndex ];
price += OS[ form.elements[ 'OS' ].selectedIndex ];

alert(myForm.cu stomerName.valu e+ " your new computer costs "+"$"+price +
".00");
}

<-- this is my entire code for this program.

And what array would that be. I see three, four if you include the forms
collection, and no need to loop through any of them.
