Angular 2 : Logout all open tabs automatically when user logs out in one of them -


i have created login page, based on sessionstorage. on loading page have checked value of sessionstorage. if opened web page in more 1 tab , logout 1 of tabs, remaining pages should logout automatically.

please me run script, when user view page or other way solve problem.

on click of logout button

logout() {   const userloggedout = this.loginservice.changestatuslogout(this.isauthenticated.getloginstatus(),                                                            this.isauthenticated.getloggedinuserid()); if (userloggedout) {   const link = ['login'];   this.router.navigate(link);  } }  changestatuslogout(status: boolean, userid){   if (userid && status) {     sessionstorage.removeitem('userid');     sessionstorage.removeitem('usergroup');     sessionstorage.removeitem('userlogedin');   return true;   } }  getloginstatus() {     const checkstaus = sessionstorage.getitem('userlogedin');     if (checkstaus === 'true') {     return this.userloggedin = true;     } }  getloggedinuseridgroup() {   const loggedinusergroup = sessionstorage.getitem('usergroup');   return loggedinusergroup;   }

you can use storage events notified when localstorage values changed.

function storagechange (event) { if(event.key === 'logged_in') {     alert('logged in: ' + event.newvalue) }}  window.addeventlistener('storage', storagechange, false)

if, example, 1 of tabs logs out:

window.sessionstorage.setitem('logged_in', false)

then other tabs receive storageevent, , alert appear:

logged in: false
