Arrays and Prompt

[JoeForts]

I'm doing a deck of cards javascript code.

What I want: Ask the user to pick a card between 1-52.
What I have to so far: is 0-51...how would I kick that up so that I get the 0 out of the way.

<script language="javascript" type="text/javascript">


var name = prompt("Choose a Card between 1 and 52",0);
var card = new Array(51);

//Cards Name, Suit, Value and Display from ace to king
card[0] = new Array("Ace","Club","1","\u2663");
card[1] = new Array("Ace","Spade","1","\u2660");
card[2] = new Array("Ace","Heart","1","\u2665");
card[3] = new Array("Ace","Diamond","1","\u2666");

^^These go all the way up to the king[51]^^

document.write("Card Name : " + card[name][0] + "<br>");
document.write("Suit : " + card[name][1] + "<br>");
document.write("Value : " + card[name][2] + "<br>");
document.write("Symbol : " + card[name][3] + "<br>");

Everything works, I just want to know how I make it so that card [0] will be card 1 when the user types it in.

Thanks, Joe

Add 1.

Subtract 1.

Sorry but your gonna have to tell me where in the code to put it...

I know I have to do a -1 somewhere.

I got 0 to 51, thats 52 arrays I just want the numbers to match so that when the user types in 1 he gets card[0]

What size array is created by the following:

var card = new Array(51);

Hint: the specified number is not the highest index value.

I just want the numbers to match so that when the user types in 1 he gets card[0]

If the user enters 1 and you read it into the variable 'name', and you want card[name] to be card[0], what do you have to do to 'name'? In other words, what mathematical operation do you have to perform on 1 to make the result equal to 0?
