General Practices

is this correct ?

x = "SomeName";

function Add() {

x = "Add";

console.log("Add");

}

//Functions

window.Add();

//Global variables,window object

console.log( window.x );

Window Object

Window.add = function () { };Window.x = “SomeName”

Own Namespace

Self-Executing Anonymous Function

(function(mySpace,undefined ) {

}( window.mySpace = window.mySpace || {}));

Check the global space for mySpace and assign a new one if not available

Leave the undefined as undefined.

Properties

(function(mySpace,undefined ) {

//Private

var x = 1;

//Public

mySpace.y = "2";

}( window.mySpace = window.mySpace || {}));

Console.log(mySpace.y)

Console.log(mySpace.x) – Not accessible

Methods

(function(mySpace,undefined ) {

//Public

mySpace.add = function() {

console.log("Add")

};

//Private

function addItem( ) {

console.log("AddItem")

}

}( window.mySpace = window.mySpace || {}));

Classes and Objects

mySpace.Class1 = function () { };

mySpace.Class1.prototype = {

methodOne: function () {

return "methodOne";

},

methodTwo: function (para) {

console.log(para);

}

};

var a = new Class1();

a.methodOne();

JSOMJavaScript Object Model

Use Js files available in Web Server Extensions\15\TEMPLATE\LAYOUTS

JSOM

SharePoint Hosted

SP.SOD.executeFunc('sp.js', 'SP.ClientContext', function () { // Do });
