I wrote a small html/js as shown below:

//ODATA Root Service URI
var CUSTOMERS_ODATA_SVC = "http://services.odata.org/Northwind/Northwind.svc/Customers";
//Page Load Actions
function OnPageLoad()
{
GetCustomers();
}
//Page Events:

function GetCustomers()
{
$("#loadingCustomers").show();
alert("ok");
OData.read(CUSTOMERS_ODATA_SVC, GetCustomersCallback);
}
//GetCustomers Success Callback
function GetCustomersCallback(data, request)
{
$("#loadingCustomers").hide();
$("#customers").find("tr:gt(0)").remove();
ApplyTemplate(data.results)
}
//*************************Helper Functions***************************
//Helper function to apply UI template
function ApplyTemplate(data)
{
var template = "<tr id=\"customerRow${CustomerID}\">" +
"<td>${CustomerID}</td>" +
"<td>${CompanyName}</td>" +
"<td>${ContactTitle}</td>" +
"<td>${Address}</td>" +
"<td>${City}</td>" +
"</tr>";
$.tmpl(template, data).appendTo("#customers tbody");
}
Could not understand what went wrong here.
Got it. Have to add the following line:
OData.defaultHttpClient.enableJsonpCallback = true;
Hopefully, this would help others.
