Populating another field via Ajax

[patsfans]

I've got a form where I have two text fields. The first one is an autocomplete field that loads two variables, "item" and "description" via AJAX as a user enters in letters.

What I'm trying to do is the following:

When they click on the item, it populates the field with the item name, but I'd like for it to next populate the adjacent textfield with the description onblur (ie: when the user moves on to another field).

Here's the code:

PHP Code:

$().ready(function() {
    $("#item1").autocomplete("model_query.php", {
        width: 260,
        matchContains: true,
        //mustMatch: true,
        //minChars: 0,
        //multiple: true,
        //highlight: false,
        //multipleSeparator: ",",
        selectFirst: false
    });
}); 


and the PHP script:

PHP Code:

$q = strtolower($_GET["q"]);
if (!$q) return;

$sql = mysql_query("SELECT item as item_name, description from catalog where item LIKE '%$q%'");

while($rows = mysql_fetch_array($sql)) {
    $item= $rows ['item_name'];
    $descq = $rows ['description'];
    echo "$item\n";
} 


HTML:

PHP Code:

<div id="content">
    <form autocomplete="off">
        <p>
            ITEM: <input type="text" name="item1" id="item1" />
</div> 


These all work for the autocomplete form, but I'm at a loss as to how to move the "$description" variable into the javascript to populate that other field. Thanks in advance, and I appreciate any guidance you can provide.
