$(document).ready(function () {

    //Namespace
    window.AppLevelECT = window.AppLevelECT || {};

    //Constructor
    AppLevelECT.Grid = function (hostElement, surlWeb) {
        this.hostElement = hostElement;
        if (surlWeb.length > 0 && surlWeb.substring(surlWeb.length - 1, surlWeb.length) != "/")
            surlWeb += "/";
        this.surlWeb = surlWeb;
    }

    //Prototype
    AppLevelECT.Grid.prototype = {

        init: function () {

            $.ajax({
                url: this.surlWeb + "_api/lists/getbytitle('Customers')/items?$select=BdcIdentity,CustomerID,ContactName",
                method: "GET",
                headers: { "Accept": "application/json; odata=verbose" },
                success: this.showItems
            });
        },

        showItems: function (data) {
            var items = [];

            items.push("<table>");
            items.push('<tr><td>Customer ID</td><td>Customer Name</td></tr>');

            $.each(data.d.results, function (key, val) {
                items.push('<tr id="' + val.BdcIdentity + '"><td>' +
                    val.CustomerID + '</td><td>' +
                    val.ContactName + '</td></tr>');
            });

            items.push("</table>");

            $("#displayDiv").html(items.join(''));
        }
    }

    ExecuteOrDelayUntilScriptLoaded(getCustomers, "sp.js");
});
