Access an array outside of a function
<p>I have a shopping cart, within the cart I want to store 4 items for each item </p>

<pre><code>[0] DB id
[1] description
[2] cost
[3] item id
</code></pre>

<p>So I have whipped up a 2d array</p>

<pre><code>var x=0;
var items= new Array();
var itemNum = 0

Function add(id, desc, cost )
{
items[x]=new Array(4);
items[x][0]=item;
items[x][1]=desc;
items[x][2]=cost;
items[x][3]=itemNum;
x++
itemNum++
}
</code></pre>

<p>How do access the array outside the function?</p>
