JavaScript not loading

HI,

I am trying to make a Sqlite project using gears API. I have downloaded the gears_init.js file locally. The sample application for Gears povided by BB is woking fine. But when I am tring to modify the same & use in my application the javascripts do not load. The index.heml page is loaded but none of the javascripts are invoked.

BB simulator : Storm 9550, 5.0.0.469

Browser :blackberry

N/w : both CDMA & GSM

THe index.html file:

title>Data Storage Example</title>
    <link href="Styles/styles.css" rel="stylesheet" type="text/css" />
    <script src="http://www.google.com/jsapi?key=ABQIAAAAsm1sbQmJWbgLoP7i4K2WdBR_SoAUqeLrvjUVmFG1nkbo-KiRrxRswNhze0oP..." type="text/javascript"></script>  
    <script src="Scripts/action.js" type="text/javascript"></script>
    <script src="Scripts/gears_init.js" type="text/javascript"></script>
    <script type="text/javascript">
    function myAlert(){
    	alert("Alert from HTML");
    }
    </script>
</head>
<body onload="javascript&colon; demoAlert(); myAlert(); openDatabase(); populateShoppingListTable()">
	<div>
	    <p class="header">Save shopping list items</p>
	</div>
    <div>
		<p class="listTitle">Items</p>
		<input type="text" id="txtItem" />
		<br/>
		<br />
		<input type="button" value="Add item to list" onclick="addShoppingListItem(document.getElementById('txtItem').value)" />
	</div>

The action.js file:

// Global handle to the database
var _db;

// Open the database using Google Gears API and create a table if needed
function openDatabase() {
	alert("kasiey ho anna");
    var db = google.gears.factory.create('beta.database1');
    db.open('itemSet1');
    db.execute('create table if not exists ShoppingListTable (Serial text unique, ItemName text, PurchaseStatus text, Rate text, Qauntity text)');
    _db = db;
}

function demoAlert(){
	alert ("I am  a jokings");
}

// Save the selected Items
/*function saveItems(item) {
    try {
        // Add the link into the database if the checkbox is checked
        _db.execute('insert into Items values (?)', [item]);
        // Update the table
        populateTable();
    }
    catch (e) {
        alert(e);
    }
}*/

function addShoppingListItem(itemname) {
    try {
    	alert(itemname);
    	var count = _db.execute('Select COUNT(ItemName) from ShoppingListTable');
    	var serialNum = count+1;
        // Add the link into the database if the checkbox is checked
        _db.execute('insert into ShoppingListTable (Serial, ItemName) VALUES ('+ serialNum + ', '+itemname+')');
        //@@@@@@@@@@@@@@@@@Select COUNT(Supplier_ID) from suppliers
        // Update the table
        populateShoppingListTable();
    }
    catch (e) {
        alert(e+"In add Shopping Item");
    }
}

Check your onload statement

<body onload="javascript&colon; demoAlert(); myAlert(); openDatabase(); populateShoppingListTable()">

what does "javascript&colon;" perform?

Also, I believe that:

"google.gears.factory.create('beta.database');"

is a fixed term, so you cannot change the classname to "beta.database1".

If you want to change the database name, you have to change the parameter for "db.open('database1')".

I think, this one will cause problems, too - I may be wrong, though.

_db.execute('insert into ShoppingListTable (Serial, ItemName) VALUES ('+ serialNum + ', '+itemname+')');

Instead use:

_db.execute('insert into ShoppingListTable (Serial, ItemName) values (?,?)', [serialNum, itemname]);

Along with this I also had to change some other JScripts which were giving errors.
