Use the browser back button with pages loaded by Ajax?

$(document).ready(function () {
$('#gnav a').click(function (e) {
        e.preventDefault();
        $('#contents').load(this.hash.substr(1) +'.php')
    });
});

That is my jQuery cod开发者_JAVA技巧e that loads some content into a div via Ajax. How can I make use of the browser back button with that code?

Thanks!

You could use the HTML5 history APIs described at http://diveintohtml5.ep.io/history.html -- that gives you complete control of back/forward behaviour for your internal navigation.

There is a nice jquery plugin called BBQ http://benalman.com/projects/jquery-bbq-plugin/ Easy to use, documentation is on the page

Another plugin you should consider is JQuery Address. I used it on a project and found it pretty flexible.

Enables "Deep linking" so you can use it to fire ajax calls based on anchor/query string. http://www.asual.com/jquery/address/
