Question

I have an application which open several windows (with javascript) in the same domain.

I would like to share some javascript objects between these windows (an object which contains some configurations for example).

Is it possible to do this in javascript and how to do this ?

Thanks.

There are 2 possibilities: local storage and session storage

The session storage stores value for duration of the session, the value gets deleted when browser is closed and re-opened.

// Store value
sessionStorage.setItem('key', 'value');
//or
sessionStorage['key'] = value; 
// Retrieve value
alert(sessionStorage.getItem('key'));

The local storage stores value beyond the duration of the session, the value can be retrievedeven after closing and re-opening the browser.

// Store value
localStorage.setItem('key', 'value');
//or
localStorage['key'] = value; 

// Retrieve value 
alert(localStorage.getItem('key'));
