We're going to do this on the input field on the add page.…So go to add.js,…and the first thing we need to do…is we need to declare…var app is equal to winJS.Application.…We need a reference to the application…because that is where session data lies.…That's how we're going to access it.…On the ready function, we are going to add a listener…to that room input, which is the ID…of that input in the DOM.…And we are going to say addEventListener.…
And the event that we're listening for is input,…and we're going to say…
