Functionalities can be performed on CROS Domain

• Get, Set Cookie

• Get, Set & Delete Local Stroage

• Bi-directional message thread

• Run JS expression from one domain to other

• DOM Manipulation from one domain to other domain ( Iframe )

All above methods are wrapped in a promise.

Initialize Bifrost-CORS You have to Initialize Bifrost-CORS in both domain

var bifrostCors = new bifrostCors(address, iframeBoolean,iframeId)	

Parameter	Required	Value
address	YES	Exact Address of the other domain
iframeBoolean	No	true :- If you already rendering the other domain in iframe false If you are not rendering the other domain in iframe Default false
iframeId	No	if iframeBoolean is set to true then you need to pass the ID for your Iframe in which you loading the other domain

Implementation of methods and how to handle promise

var bifrostCors = new bifrostCors("http://example.com/",false)

//Calling Methods without promise
var result = bifrostCors.getLocalStorage(key)

//Hanlde Promise

//1. Using .then()
bifrostCors.getLocalStorage(key).then((data) => {
	console.log(data)
 })

//2. Using async function
async function grabLocalStorage(){
	let result = await  bifrostCors.getLocalStorage(key)
}

Functionalities

• Cookies

  • Get Cookies

  // return type Object, return all cookies
  bifrostCors.getCookie() 
  
  // return type string
  bifrostCors.getCookie("key")
  

  • Set Cookies

  bifrostCors.setCookie(name,value,days)   
  

  • Parameter
    • name String, name for cookie
    • value String, value for cookie
    • days int, expiration days for cookie
  • return type Boolean

• LocalStorage

  • Get local Storage

  // return type stirng
  bifrostCors.getgetLocalStorage("key") 
  
  // return type array
  bifrostCors.getLocalStorage(["key1","key2"])
  

  • Set local Storage

  // return type Boolean
  bifrostCors.setLocalStorage({key: "user", value: "user-1"}) 
  

  • Delete local Storage

  // return type Boolean
  bifrostCors.deleteLocalStorage("key") 
  
  // return type Boolean
  bifrostCors.deleteLocalStorage(["key1","key2"])
  

• Bi-directional message thread

  • Request Message Thread

  // return type Boolean, parameter type funtion
  bifrostCors.requestMessageThread(Listner)
  

  Listner is your custom function which will be invoked every time new message recivied, and it should expect a new message as a parameter

  Here's exapmle

  function myCustomListner(newMessage){
  	cosnole.log("Hurray I got new message ",newMessage)
   }
   
   bifrostCors.requestMessageThread(myCustomListner)
  

  • Send Message

  // return type Boolean, parameter type string|int|array|object
  bifrostCors.send(message)
  

• Run JS expression

  // return type Boolean, parameter type string
  bifrostCors.runExpression(expression)
  

• DOM Manipulation

  • DOM Manipulation by ID

  // return type Boolean, parameter type string
  bifrostCors.domManipulationById("yourElementID")
  

  • DOM Manipulation by class name

  // return type Boolean, parameter type string,int,Objet
  bifrostCors.domManipulationById(class,index,style)
  

  • Parameter
    • class String your element class name
    • index int index no of that element in class array
    • style Object Style object
  • Example:a if you can access element by document.getElementsByClassName("myElementClass)[4]
    so parameter will be
    
    • class "myElementClass"
    • index 4
    • style {background:"red"}
