Suppose I have 2 html files: form.html and confirm.html
form.html just have a text field and a submit button, when you hit submit it will display what you just typed
What you could do is submit the form using a get method (method="get"), and send it to your confirm.html page (action="./confirm.html").
Then, you could use jQuery to retrieve the values from the URL from your confirm.html page.
This website provides a method to do that: http://jquerybyexample.blogspot.com/2012/06/get-url-parameters-using-jquery.html .
Then, all you have to do is call your display() method.
