Retrieving application state information in the detail page

The detail page defines an onload function that executes as soon as the page is loaded:

<body onload="onloadHandler()"...>

The onloadHandler() function accesses the specific data for the customer row that the user tapped and binds it to the detail page template:

function onloadHandler() {
    // Retrieve dbname and CustomerID.
    var dbname = avantgo.preferences.getStringValueForKey("ListPage_dbname");
    var id = avantgo.preferences.
        getStringValueForKey("detailPage_"+dbname+"Id");

    dbset = dbMgr.open(dbname, r");
    if(dbset == null) {
        alert("Could not open the '" + dbname + "' database.");
        return;
    }

    // Locate the customer record that matches CustomerID.
    var search = dbset.createSearch("CustomerID ==" + id);
    dbset.setFilter(search);
    dbset.moveFirst();

    // Bind customer data to detail page template.
    document.getElementById("customer_name").firstChild.data = 
         dbset.ContactName;
    document.getElementById("customer_title").firstChild.data = 
         dbset.ContactTitle;
    document.getElementById("customer_company").firstChild.data =
         dbset.CompanyName;
    document.getElementById("customer_address").firstChild.data =
         dbset.AddressLine1;
    document.getElementById("customer_city").firstChild.data =
         dbset.City;
    document.getElementById("customer_zip").firstChild.data =
         dbset.PostalCode;
    document.getElementById("customer_country").firstChild.data =
         dbset.Country;
    document.getElementById("customer_phone").firstChild.data =
         dbset.Phone;
    document.getElementById("customer_fax").firstChild.data =
         dbset.Fax;
    }

Note

The labels above following .firstChild.data = dbset. match the data object labels in the XML file downloaded to the mobile device.
