Passing data between a parent window and a child popup window with jQuery

Question

I have the following HTML

<tr>
    <td class="label" valign="top">
        Affiliate Party
    </td>
    <td class="field">
        <input type="hidden" name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyId" id="AffiliatePartyId" />
        <input name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyName" type="text" id="AffiliatePartyName" class="PartyLookup" />
    </td>
</tr>

and the following Javascript/jQuery

$(".PartyLookup").after("<img src='Images/book_open.png' class='PartyLookupToggle' style='padding-left:4px;' />");

$(".PartyLookupToggle").click(function () {
    window.open("PartySearch.aspx", "PartySearch", "width=400,height=50");
    return false;
});

I need to be able to flag ANY PartyId input field with class="PartyLookup" so that it will modify the DOM and include the image next to the input field. The popup window returns data to populate both the hidden and text fields, but since the click() is generic I need to pass it the ID of the input field. I have no idea how to do this. Any suggestions?

Script on parent page:

$(".PartyLookupToggle").click(function () {
    var id = $(this).prev().prev().attr("id");
    var name = $(this).prev().attr("id");

    var url = "PartySearch.aspx?id=" + id + "&name=" + name;

    window.open(url, "PartySearch", "width=400,height=50");
    return false;
});

Script on child page:

// Get the values from the URL using the jquery.query plug-in
var id = $.query.get("id");
var name = $.query.get("name");

// Get the values from the drop down
var newPartyId = $("#ddlMatchingParties").val();
var newPartyName = $("#ddlMatchingParties option:selected").text();

// Set them to the parent window
window.opener.$("#" + id).val(newPartyId);
window.opener.$("#" + name).val(newPartyName);

// Close the popup
window.close();
