Listing 6-23. Binding to a Persona Login and Logout

document.querySelector("#login").addEventListener("click", function() {

navigator.id.request();

}, false);

document.querySelector("#logout").addEventListener("click", function() {

navigator.id.logout();

}, false);

Persona also needs you to implement a watch function that will listen for these events. When one is detected, it will send an XMLHttpRequest to the /persona/verify or /persona/logout routes in your Express.js application.

Listing 6-24. Persona Navigator watch Method

navigator.id.watch({

onlogin: function(assertion) {

var xhr = new XMLHttpRequest();

xhr.open("POST", "/persona/verify", true);

xhr.setRequestHeader("Content-Type", "application/json");

xhr.addEventListener("loadend", function(e) {

var data = JSON.parse(this.responseText);

if (data && data.status === "okay") {

console.log("You have been logged in as: " + data.email);

}

}, false);
